How to Upload Multiple Image in Laravel

rajeshkumar — Sun, 13 Jun 2021 07:16:37 +0000

In this turoial im going to learn how to upload multiple image in laravel and store in database. Image upload is necessary of every project. In this project i’m going to learn how to upload with validation like images, mimes, max file upload and etc.

So let’s go to download project and configure with database. so copy below code and paste in your terminal.

First let’s go to install laravel project

composer create-project laravel/laravel admin-dashboard "5.8.*"

After Installation setup database So go to the .env file and add the database credentials. lets go to .env folder and put database name and connect to database.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=admin-dashboard
DB_USERNAME=root
DB_PASSWORD=

Now migrate the table

php artisan migrate

Lets go to create migration file to store the image name go to your terminal and paste below code.

php artisan make:migration create_forms_table

Let’ go to migration table and add file name.


use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateFormsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('forms', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('filename');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('forms');
    }
}

The next step will be to migrate this schema and make a table in the database.

php artisan migrate

Next go to create the controller and model file for this project copy below code and paste in your command.

php artisan make:model Form

php artisan make:controller FormController

lets got to setup the model and controller file for our project.

Step 2: Define routes in the web.php file.

copy below code and paste in your route/web.php file


/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    return view('welcome');
});

Auth::routes();

Route::get('/home', 'HomeController@index')->name('home');

Route::get('form','FormController@create');
Route::post('form','FormController@store');

Go to your controller and paste below code in your controller


namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Form;

class FormController extends Controller
{
    public function create()
    {
        return view('create');
    }

    public function store(Request $request)
    {
        $this->validate($request, [
            'filename' => 'required',
            'filename.*' => 'image | mimes:jpeg,png,jpg,gif,svg|max:2048'
        ]);

        if($request->hasfile('filename'))
        {
            foreach($request->file('filename') as $image)
            {
                $name=$image->getClientOriginalName();
                $image->move(public_path().'/images',$name);
                $data[] =$name;
            }
        }

        $form= new Form();
        $form->filename=json_encode($data);

        $form->save();

        return back()->with('success', 'image has been successfully updated');
    }

    
}

Now, let us make a create.blade.php file inside the Resources/views folder.

@extends('layouts.app')
@section('content')



      @if (count($errors) > 0)
      
        Whoops! There were some problems with your input.


        
          @foreach ($errors->all() as $error)
              {{ $error }}

          @endforeach
        

      

      @endif

        @if(session('success'))
        
          {{ session('success') }}
        
 
        @endif

    Laravel Multiple File Upload


  {{csrf_field()}}

        
          
           
            
          

        

        
          
            
             
              
            

          

        


        

  
        
  





@endsection

Now let’s go to your browser and paste below code

http://127.0.0.1:8000/form

Now image has been successfully added in database as well.

Thanks i hope its helpfull for you. Amit Kumar

        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('posts');
    }
}

Next go to Post model and paste below code


namespace App;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    protected $fillable=[
        'title',
        'description'
    ];
}

Now migrate the table run below command

php artisan migrate

Step 4 — Create Routes


use Illuminate\Support\Facades\Route;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    return view('welcome');
});

Route::get('add-blog-post-form', [PostController::class, 'index']);
Route::post('store-form', [PostController::class, 'store']);

Step 5 — Creating Controller

php artisan make:controller PostController -r

Go to your Post controller file and paste below code


namespace App\Http\Controllers;

use Illuminate\Http\Request;use App\Post;class PostController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        return view('add-blog-post-form');
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        //
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $post = new Post;

        $post->title = $request->title;
        $post->description = $request->description;

        $post->save();

        return redirect('add-blog-post-form')->with('status', 'Blog Post Form Data Has Been inserted');
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        //
    }
}

Step 6 — Create Blade File For Form

add-blog-post-form.blade.php

Go to Resources/views/add-blog-post-form.blade.php and create this file

CRUD Operation Detailed Explaination with Example.

abhishek k — Mon, 08 Mar 2021 13:12:48 +0000

Before performing CRUD operations we need to do some of the basic tasks. These includes:- 1. Installing Laravel 2. Creating Laravel Project 3. Making Model 4. Migrating After that we are good to go for the operation.

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 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 $note->id])}}” type=”button” class=”btn btn-primary”>Edit 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.
