This error is PHP fatal error: and complete display image is

What we need to do to remove this ?

Folllow the below steps:

1. Close the xampp if its running.
2. got to “C:\ProgramData\ComposerSetup\bin” (we can copy the location and paste it in the explorer header)

just press on the above header (after pc) and paste the location and press enter

This will open the file location:

3. We then need to open the composer.bat to edit it (right click on it and click on edit with notepad++)

4. Now just copy the below code and replace it with the code present in composer.bat

Code:

@echo OFF
:: in case DelayedExpansion is on and a path contains ! 
setlocal DISABLEDELAYEDEXPANSION
php -d memory_limit=-1 "%~dp0composer.phar" %*

5. Now save it. For saving it

• Press (Ctrl + S)
• we will be prompted as run as Administrator.
• press Allow

Then we just need to install the passport and do the changes to the places where needed.

Command to install Passport:

php artisan passport:install

Soon after the passport is install we will get the following things:

1. Client id
2. Client secret

We need to put client id in the in env files where required.

Somewhat similar to given below:

We need to change the client id and client secret to all the places where the concern configuration are used.

The post Built-in/Predefined Methods in JavaScript appeared first on scmGalaxy.

Few Important things of Methods:-

• In JavaScript, however, a method is a function that belongs to an object.
• JavaScript methods are the actions that can be performed on objects.
• A JavaScript method is a property containing a function definition.
• Accessing the object method is done with the following syntax: objectName.methodName()

Just similar to the functions in JavaScript methods are also classified in two categories:-

1. Predefined
2. User-defined

Predefined methods can be used directly by calling and giving parameter values (if required). while user-defined methods are first declared, defined, and then used in the program.

Deceleration and definitions of User-defined methods are done together we could understand better seeing the below code.
Syntax of Methods

object = {
    methodName: function() {
        // Content
    }
};

object.methodName()

How to access the Object Methods

we can access the object method with the following syntax stated below:-

objectName.methodName()

How to add the method to Object.

person.name = function () {
    return this.firstName + " " + this.lastName;
};

We could also directly use the built-in method.

var message = "Display message of your choice";
var x = message.toUpperCase();

The above method would just convert the text entered as a message to uppercase.

The post Methods in JavaScript appeared first on scmGalaxy.

• Methods have a “receiver” while functions do not.
• Functions and methods are the same in JavaScript, but a method is a function, which is a property of an object.
• Syntax for calling/ definition/declaration of functions and methods are different.
• A function can be called directly by its name but methods are called by its object name and its method name using dot notation or square bracket notation.
• Function passes the data and methods operates the data passed in the class.
• A function lives on its own but method is a function associated with an object property.
• Data passed to a function is explicit but method implicitly passes the object on which it was called.

Lets see detailed difference between them:-

A function in JavaScript is similar to a procedure —>a set of statements that performs a task or calculates a value, but for a procedure to qualify as a function, it should take some input and return an output

Few Important things of functions:-

• The function is executed when something calls/invokes it.
• The name may contain letters, digits, dollar signs, underscore.
• Parameters are listed inside round parenthesis after the name of the function.
• Arguments are values a function receives when it is invoked.
• When the control reaches the return statement, js will stop executing and the value is returned to the caller.

There are three steps of Functions as well as Methods to use in the program.

1. Declaration
2. Definition.
3. Call

In JavaScript function declaration and definition are mostly done together.

A JavaScript method is a property of an object that contains a function definition. Methods are functions stored as object properties.

Few Important things of Methods:-

• In JavaScript, however, a method is a function that belongs to an object.
• JavaScript methods are the actions that can be performed on objects.
• A JavaScript method is a property containing a function definition.
• Accessing the object method is done with the following syntax: objectName.methodName()

Syntax of Function

var func = function(a, b) {
    var sum = a + b;
    return sum;
}
  
console.log(sum(1, 2));

Syntax of Methods

object = {
    methodName: function() {
        // Content
    }
};

object.methodName()

The post Difference between Function and Method in JavaScript appeared first on scmGalaxy.

Every computer programming language has functions. Some functions are defined by the programmers while the code is being written while some functions are predefined when the language was built.

As every functions have three parts

1. Function Declaration
2. Function Definition.
3. Function Call

In predefined functions, the first two points are already done inside the library which we include as a header file at the beginning of the program. we just have to call the function.

Few most common predefined functions that we use are:-

Functions to display something in JavaScript:-

alert(message) – It displays an alert box with a message specified in it.

confirm(message) – It will display the message with two buttons. “OK” and “Cancel”.

prompt(message) – Displays a box with the message passed. There the user can enter text in the prompt field, and choose OK or Cancel. If the user chooses OK, the string value entered in the field is returned and If the user chooses Cancel, a NULL value is returned.

Functions for conversion in JavaScript:-

parseFloat() – It returns floating-point numbers the same way as the parseInt function does, but looks for floating-point qualified strings and returns their value as afloat.

parseInt()– It converts a string to an integer returning the first integer encountered which is contained in the string. If no integer values are found such as in the string “written text”, then a value of 0 is returned.

Functions for comparison in JavaScript:-

eval()– Converts a string to integer or float value.

isNaN(value) – If the value passed is not a number, the boolean value of true is returned, if it is a number, it returns false.

escape(string) – It passes the string to be encoded and returns the encoded string. Encodes a string from ASCII into an ISO Latin-1 (ISO 8859-1) character set for HTML processing.

unescape() – Converts an ISO8859-1 character set to ASCII.

isFinite() – function determines whether the passed value is a finite number. If needed, the parameter is first converted to a number.

Functions for decoding and encoding in JavaScript:-

decodeURI() function decodes a Uniform Resource Identifier (URI) previously created by encodeURI or by a similar routine. decodeURIComponent()

decodeURIComponent() method decodes a Uniform Resource Identifier (URI) component previously created by encodeURIComponent() or by a similar routine. encodeURI

encodeURI() encodes a Uniform Resource Identifier (URI) by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character (will only be four escape sequences for characters composed of two “surrogate” characters). encodeURIComponent()

encodeURIComponent() encodes a Uniform Resource Identifier (URI) component by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character (will only be four escape sequences for characters composed of two “surrogate” characters).

There are more predefined functions but these were the important ones which are often used.

php artisan passport:install

For generating key we use the following command

php artisan key:generate

Then we need to run few commands for convenience so that we don’t get errors.

php artisan c:cache
php artisan r:cache
php artisan r:clear
php artisan config:clear
php artisan view:clear

If the error shows as Replicating claims as headers are deprecated and will remove from v4.0. Please manually set the header if you need it replicated. then run the following command

composer require lcobucci/jwt=3.3.3

We can also check for updating composer and for this we use command

php artisan composer:update

to link the storage we need to run following command

php artisan storage:link

We can also do for our convenience migrating the database, for this we use command

php artisan migrate 

For refreshing the migration table

php artisan migrate:refresh

A JavaScript function is a block of code designed to perform a particular task. In simple terms, Functions are used to make work easy, reduce the effort of coding multiple lines for the same task which is needed to repeat multiple times.

1. Function Declaration
2. Function Definition.
3. Function Call

In JavaScript function declaration and definition are done together.

When variables are defined inside a function then they cannot be used outside of it, these types of variables are called local variables, and when variables are declared outside the function then we can use them anywhere these are global variables.

The post A brief description of JAVASCRIPT appeared first on scmGalaxy.

The easiest way of implementing AJAX, is by using jQuery.

To add jQuery

We can use the downloaded version from (jquery.com/download/) and we need to include the file location of the file in the script under the header tag, or we can use the CDN in the head of HTML as

<head>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

</head>

After we are good to go with the operations we need to perform. If we wanna test that the CDN works fine we can use the function below in the body of the HTML script

<script>
$(document).ready(function(){
    alert("jQuery Works")
});
</script>

If we see the jQuery works alert, That mean we can congratulate ourselves on our success.

The post AJAX Setup/ Installation appeared first on scmGalaxy.

It is a web development technique that helps to create a highly responsive website. by the use of AJAX, we get desktop-like software experience on the web browser. It is used in the web pages to be updated asynchronously by changing data with a web server behind the scene (in the background). This makes it possible to update parts of a web page, without reloading the whole page. It is the use of the XMLHttpRequest object to communicate with server-side scripts.

The easiest way of implementing AJAX, especially if we’re planning on communicating with servers is by using jQuery.

Most people get confused with the concept that ajax is a programming language. So, let’s be very clear that

Ajax is not a programming language, it is a web development technique designed to create highly responsive/ interactive websites. To have a better understanding of AJAX we need to have knowledge of javascript and somewhat XML.

Javascript is a scripting language that helps to make web pages interactive, CSS (Cascading style sheet) style sheet to the makeup of the webpage and XML (extensible markup language ) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. here javascript and CSS are essentials and XML is less essential for the beginners

Why use AJAX

1. A whole page reload is not required on each request made.
2. Sends and receives data in the background.
3. Improves speed and performance.
4. Provides a better user experience.

How AJAX works

Ajax uses XMLHttpRequest object (also called XHR objects) to achieve this

1. When the user sends a request from the interface then the javascript directs to the XMLHttpRequest object.
2. Then the HTTP Request is made to the server by XMLHttpRequest object.
3. Then the server interacts with the database using the JSP, PHP, Servlet, ASP.net, etc.
4. When there is a match for the request then the Data is retrieved from the database.
5. Then the Server sends XML data or JSON data to the XMLHttpRequest callback function.
6. Finally, when all the things are good to go then the web-page made (with HTML and CSS) is displayed on the browser.

After the create operation we need to store the data in the database for this we used <form action=”{{route(‘store’)}}” method=”POST”> which will call store function. The store function be like

The in store function we create object $var of Task class make variables as $var->task which is assigned $request->task; (gets value from 1^st field) & $var->detail which is assigned $request->detail; (gets value from 2^nd field) and $var->save(); function will save it to the database.

1. Using a keyword “validate” inside the input tag (<input type=”text” name=”userid” placeholder= “User-Id” size=”20″ required />).

This Will present output as:-

Complete code for the above form is shared below :-

Presented output for the above operation :-

2. Using function call we need to define a function that will validate the field data and return corresponding errors.

We need to write the html code for input field in the form

<form><label><b> User-Id</b>  </label>   <input type=”text” name=”userid” placeholder= “User-Id” size=”20″ id=”userId” /> <p id=”error1″></p></form>

First we need to call the function on submit of form as (<form name=”myForm”  onsubmit=”return validateForm()” methord=”post”>) Then we need to define the function

This would produce output as

Complete code for the above function is shared below :-

Conclusion:- Validating a form in javascript is easy and is done with the function call and displays an error with respect to the type of input in the field.

The post Registration Form Validation Using Javascript appeared first on scmGalaxy.

Explanation for the above operations is given in link below https://www.scmgalaxy.com/tutorials/crud-operation-prerequisites/

5. Create Operation

Create a folder Under resource =>view => Task =>File_name (say create.blade.php) and code the Html part in it.

We will now move to route(web.php) and create a route for the view . We will use Route::get(‘create’,’TaskController@index’)->name(‘create’);

We will now move to route(web.php) and create a route for the view to display. name(‘task‘) is given in the URL as http://127.0.0.1:8000/task. Control flow:- As the URL is hit the control will go the route(web.php), there we will write Route::get(‘create‘,’TaskController@create’)->name(‘create‘); Here, there will be a name match from the URL and if there is a match then there will be a function call named create and route will redirect to TaskController.php where it will find the function create and operate according to the instructions given in it. }

The TaskController.php will get to the create function definition Here this function will return a view create.blade.php, which has html codes, Output displayed on the browser.

After the create operation we need to store the data in the database for this we used <form action=”{{route(‘store’)}}” method=”POST”> which will call store function. for that, we need to call the store function when the user clicks submit after entering the data on the above page. The store function be like

In the store function we create object $var of Task make variables as $var->task which is assigned $request->task; (gets value from 1^st field) & $var->detail which is assigned $request->detail; (gets value from 2^nd field) and $var->save(); function will save it to the database.

Soon after the data is created and stored in the database, we can view it by performing Read operation.

6. Read operation

Create a file in resource =>view => Task (say, task.blade.php). and code the Html part in it.

We will now move to route(web.php) and create a route for the view to display. We will write the name(‘task‘) is given in the URL as http://127.0.0.1:8000/task. Control flow:- As the URL is hit the control will go the route(web.php), there it will write Route::get(‘task’,’TaskController@index’)->name(‘task’); Here, there will be a name match from the URL and if there is a match then there will be a function call named index and route will redirect to TaskController.php where it will find the function index and operate according to the instructions given in it. }

Here this function will return a view taskIndex.blade.php, which has HTML codes, which is to display on the browser with all the things compact.

7. Update operation

Create a file in resource =>view => Task => File_name (say, edit.blade.php). and code the Html part in it.

For update we need to give an edit button which calls the update function when clicked. for this we used <a href=”{{route(‘notes.edit’,[‘id’ => $note->id])}}”  type=”button” class=”btn btn-primary”>Edit</a> This will redirect to route (web.php) where we will write Route::get(‘edit’,’TaskController@edit’)->name(‘edit’); Here, there will be a name match from the URL and if there is match then there will be a function call named edit and route will redirect to TaskController.php where it will find the function edit and operate according to the instructions given in it. This will call edit function

This will find the corresponding id and return the edit page view with the details prefilled in it.

On click of submitting after changing the details which were prefilled, This will redirect to route (web.php) where we will write Route::post(‘update/{id}’,’TaskController@update’)->name(‘update’); Here, there will be a name match from the URL and if there is a match then there will be a function call named update and route will redirect to TaskController.php where it will find the function update and operate according to the instructions given in it. The update function will run.

In the Update function we create object $var1 of Task which finds and matches id and make variables as $var1->task which is assigned  $request->task; (gets value from 1^st field) & $var1->detail which is assigned $request->detail; (gets value from 2^nd field) and $var1->save(); function will save it to the database. and return redirect() will redirect the route to task.

7. Delete Operation

Implementing delete operation is easy and we need to Just provide a delete button in the html view which will help call the destroy function.

On click of Delete button This will redirect to route (web.php) where we will write Route::post(‘delete/{id}’,’TaskController@delete’)->name(‘delete’); Here, there will be a name match from the URL and if there is a match then there will be a function call named delete and route will redirect to TaskController.php where it will find the function delete and operate according to the instructions given in it. The update function will run.

In the Update function we create object $var2 of Task which finds and matches id and $var1->delete(); function will delete it from the database. and return redirect() will redirect the route to task.

The post CRUD Operation Detailed Explaination with Example. appeared first on scmGalaxy.

Laravel the most popular PHP-based framework for creating database-driven apps is based on the MVC (Model-View-Controller) architecture and can be used for easily creating apps for making CRUD (Create, Retrieve, Update, Delete) operations in the database.

1. Installing Laravel The first and foremost thing we need to have Laravel and composer installed in our system. the command for installation is
composer global require “laravel/installer=~1.1”
if this does not works then we could just write
composer global require “laravel/installer”
and it would install the file.
2. Creating Laravel Project Then we need to create a project and for this, we need to type
composer create-project –prefer-dist laravel/laravel project_name “5.8.*”
If this does not works then we could just write
composer create-project –prefer-dist laravel/laravel project_name
it would create a Laravel project named blog (with the latest version).

3. Making Model and Migrating After the project is created we need to create the Model. For this we use command.

$ php artisan make:model Model_name -mcr or $ php artisan make:model Model_name -a

(Note:- Model name should begin with a capital letter) Here mcr is (migration controller resources) we can use m/c/r separately but for better convenience, we use “a“ which can equivalently be used in place of “mcr”.

After the model is created we need to create the database and attach it. We can instruct for the database creation through codes or we can go to PHPMyAdmin, and there we can create the database and provide the name of the database in the .env file

After database creation, we need to migrate. Migrations allow to add or drop fields in the database without deleting the records already present. for this we use $ php artisan migrate We could also refresh migration using $ php artisan migrate:refresh

All the prerequisites to perform CRUD operations are completed and are ready to go. Now we can move to views to create the Html page and perform desired CRUD operations.

composer create-project –prefer-dist laravel/laravel blog “5.8”
if this does not works then we could just write
composer create-project –prefer-dist laravel/laravel blog
it would create a Laravel project named blog.

Soon after the project is created we now have to

Understanding the Folder structure

The most important thing in the Laravel project is understanding the structure of files and folders. Understanding the files and folder structure’s main purpose is to understand where we need to write codes for Html, Model, Controller, Routing, Filestore, Config, and Database.
The time after the Laravel project is created we see different folders and files. All the files and folder build while building the project have their use and gives it easy access while writing codes.
The main folder in the project consists of

Let’s take a brief look at the different folders created and the files in them.

The first one App mainly includes codes for HTML, Model, and Controller which are in folders shown below.

In the console directory, there is a kernel.php file that has codes for the custom command.
Exception folders have handler.php that includes all the codes for different exceptions.
The HTTP folder has 2 sub-folders namely controllers and middleware.

Controllers and Middleware mainly include files acting as a bridge between database and webpage. These include files for authentication login validation, registering ids, resetting the password, etc.

Cookies that are used to store some data of the user are also managed here. Controllers act as an interface between database and web-page and Middleware filters out the request.

The Model directory contains all of your model classes. It provides a beautiful, simple ActiveRecord implementation for working with your database. Each database table has a corresponding “Model” which is used to interact with that table. Models allow you to query for data in your tables, as well as insert new records into the table.

Then we have a Provider directory.

where we write different kinds of services like authentication services, routing services, and more.

Then we have Bootstrap directory that has an app.php file that helps in bootstrapping the application i.e loading the application on the browser.

Then we have a config directory that contains all the configuration files like database configurations, email configurations, session configurations, login configurations, catch configurations, and many more.

The database directory mainly includes three folders i.e factories, migrations, and seed.

Factories provide a convenient way to generate new model instances for  testing/seeding the application’s database. In Migrations, one database is shared with another database and also between developers. Seeding simply means putting the fake/dummy data in the database.

The public directory

has CSS, js, and more files that have predefined JavaScript and CSS of the project and most importantly index.php file. This is the first file that is loaded in the browser when our server (local server) is hosted.

The resource directory

is the important part where all the public files of HTML, CSS, js files are coded and sometimes local files. This directory most importantly includes views where we write the complete HTML. All the HTML pages that we want to display shall be placed here. These files can be placed directly or can placed inside the folder in views.

The route directory’s main purpose is placing the codes for URLs for the web as well as API.

The storage directory contains the app, framework, and log directory. The storage directory is used to store framework-generated files and caches. They also contain compiled Blade templates, file-based sessions, file caches, and other files generated by the framework and the log directory contains your application’s log files.

The test directory contains automated tests. We may run tests using the phpunit or php vendor/bin/phpunit commands.

Vendor directory stores all the package files which are installed by the composers.

In simple terms, the vendor directory acts as a store-keeper for all the package files for the project in laravel.

We have few more files that are necessary like environment file (env.php), composer file (composer.json), package file (package.json).

We use webpack.mix.js for integration of CSS and js files from different developers for effective use. It also serves as a better security for CSS and js files in the project so that it cannot be publicly accessed.

The best part is that Laravel works on MVC architecture

MVC stands for Model-View-Controller. It is an architectural pattern that separates an application into three main logical components Model, View, and Controller. Each architectural component is built to handle specific development aspects of an application easily.

The control flows in MVC (How MVC works)

Whenever a user requests to view something on the browser, the request is made to the controller. The controller then requests the model to return all the data which is asked for.

If there is a match the model returns the data to the controller and then the controller will instruct the view to display the data.

If there no match or error then the model returns the error to the controller and then the controller will instruct the view to display the error accordingly.

Why Laravel could be the best choice for developers.

Modularity in Laravel helps users with 20 built-in libraries and modules for enhancement of the application and maintaining the code as per the requirements.

Schema Builder is used for maintaining the database schema and related code of PHP. Track of changes is maintained with respect to database migrations.

The blade template engine is used for designing layouts with predefined blocks and hierarchical blocks that include dynamic content. As it is a lightweight template language.

Authentication feature in Laravel eases designing as it includes features such as register, send password reminders, reset forgot password.

E-mail and Queues A mail class in Laravel helps in sending mail with rich content and attachments and also includes features for queuing when users are in large numbers.

Query Builder helps in querying databases using various simple chain methods. It provides ORM (Object Relational Mapper) and ActiveRecord implementation called Eloquent.

Testing is easy in Laravel. It includes features and helpers which help in testing through various test cases. To a better part parallel testing is also possible in Laravel.

Routing helps in scaling and maintaining the code as per the requirements with the help of features and helpers.

The big question in mind Who should work with Laravel?

Laravel provides a great platform to handle PHP codes and maintaining them so, it’s a great platform for beginners to work on.  It’s very fluent, user-friendly, and easy to learn and understand which adds to its advantage making it a better choice for beginners to initiate their work.
