Post Views: 0

Laravel crud operation:-(version 5.8)

1^st step:-First we have to download laravel (version-5.8).to download laravel we have to go to command prompt, and then go to the folder path in which you want to download laravel. After this run the composer command.(command givel below):-

composer create-project laravel/laravel=5.8 crud –prefer-dist

2^nd step:- After downloading laravel, we have to make MySql database.

3^rd step:- now open .env file of the model and configure like the image given below:

4^th step:- Make the migration folder by the writing the command given below on command prompt:

php artisan make:migration create_crud_table –create=crud

This command make a migration file in database\migration in this file we have to define the required column which we want to create in the database table.

The code for migration:-

<?php

use Illuminate\Support\Facades\Schema;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Database\Migrations\Migration;

class CreateCrudsTable extends Migration

{

/**

* Run the migrations.

* @return void

public function up()

{

Schema::create(‘cruds’, function (Blueprint $table) {

$table->bigIncrements(‘id’);

$table->string(‘first_name’);

$table->string(‘last_name’);

$table->string(‘image’);

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists(‘cruds’);

}

Now we have to migrate the table to the database. The command to migrate the table to tahe database is:-

Php artisan migrate

Write the above code in command prompt.

5^th step:- Now make a model by using the command

Php artisan make:moedel model_name –m

By the above command a new file is created with .php extension in app folder.

6^th step:- Paste the code given below in the file created in 5^th step

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class crud extends Model

{

protected $fillable =[

‘first_name’, ‘last_name’, ‘image’

];

}

7^th step:- Now create controller. The code to create controller is given below

Php artisan make:controller CrudController –resource

Note: crud of CrudController is name of the model.

8^th step:- This is the most important step. In this step we set up the route for all the CrudController class method. Write the below code in route\web.php file.

<?php

|————————————————————————–

| 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::resource(‘crud’,’CrudsController’);

9^th step:- Now code the view file in resource\views folder. All the html,css and javascript code is written in this file.

We make new file for the view in resource\views\filename.blade.php

Code is given below

<!DOCTYPE html>

<head>

<title>Document</title>

</head>

<body>

@extends(‘Crud.parent’)

@section(‘main’)

</div>

@if ($message = Session::get(‘success’))

<p>{{$message}}</p>

</div>

@endif

<tr>

<th width=”10%”>Image</th>

<th width=”35%”>First Name</th>

<th width=”30%”>Action</th>

</tr>

@foreach($data as $row)

<tr>

<td><img src=”{{ URL::to(‘/’) }}/images/{{ $row->image }}” class=”img-thumbnail” width=”75″ /></td>

<td>{{ $row->first_name }}</td>

<td>

<a href=”{{route(‘crud.show’, $row->id) }}” class=”btn btn-primary”>Show</a>

<a href=”{{route(‘crud.edit’, $row->id) }}” class=”btn btn-warning”>Edit</a>

<form action=”{{route(‘crud.destroy’,$row->id) }}”

method=”post”>

@csrf

@method(‘DELETE’)

<button type=”submit” class=”btn btn-danger”>Delete</button>

</form>

</td>

</tr>

@endforeach

</table>

{!! $data->links() !!}

@endsection

</body>

</html>

10^th step:- Now code the controller.

Code for the controller

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Crud;

class CrudsController extends Controller

{

/**

* Display a listing of the resource.

* @return \Illuminate\Http\Response

public function index()

{

$data = Crud::latest()->paginate(5);

return view(‘Crud.index’, compact(‘data’))

->with(‘i’, (request()->input(‘page’, 1) – 1) * 5);

}

/**

* Show the form for creating a new resource.

* @return \Illuminate\Http\Response

public function create()

{

return view(‘Crud.create’);

}

/**

* Store a newly created resource in storage.

* @param \Illuminate\Http\Request $request

* @return \Illuminate\Http\Response

public function store(Request $request)

{

$request->validate([

‘first_name’ => ‘required’,

‘last_name’ => ‘required’,

‘image’ => ‘required|image|max:2048’

]);

$image = $request->file(‘image’);

$new_name = rand() . ‘.’ . $image->getClientOriginalExtension();

$image->move(public_path(‘images’), $new_name);

$form_data = array(

‘first_name’ => $request->first_name,

‘last_name’ => $request->last_name,

‘image’ => $new_name

);

Crud::create($form_data);

return redirect(‘crud’)->with(‘success’, ‘Data Added successfully.’);

}

/**

* Display the specified resource.

* @param int $id

* @return \Illuminate\Http\Response

public function show($id)

{

$data = Crud::findOrFail($id);

return view(‘Crud.view’, compact(‘data’));

}

/**

* Show the form for editing the specified resource.

* @param int $id

* @return \Illuminate\Http\Response

public function edit($id)

{

$data = Crud::findOrFail($id);

return view(‘Crud.edit’, compact(‘data’));

}

/**

* Update the specified resource in storage.

* @param \Illuminate\Http\Request $request

* @param int $id

* @return \Illuminate\Http\Response

public function update(Request $request, $id)

{

$image_name = $request->hidden_image;

$image = $request->file(‘image’);

if($image != ”)

{

$request->validate([

‘first_name’ => ‘required’,

‘last_name’ => ‘required’,

‘image’ => ‘image|max:2048’

]);

$image_name = rand() . ‘.’ . $image->getClientOriginalExtension();

$image->move(public_path(‘images’), $image_name);

}

else

{

$request->validate([

‘first_name’ => ‘required’,

‘last_name’ => ‘required’

]);

}

$form_data = array(

‘first_name’ => $request->first_name,

‘last_name’ => $request->last_name,

‘image’ => $image_name

);

Crud::whereId($id)->update($form_data);

return redirect(‘crud’)->with(‘success’, ‘Data is successfully updated’);

}

/**

* Remove the specified resource from storage.

* @param int $id

* @return \Illuminate\Http\Response

public function destroy($id)

{

$data = Crud::findOrFail($id);

$data->delete();

return redirect(‘crud’)->with(‘success’, ‘Data is successfully deleted’);

}

Code for index file

resources/views/index.blade.php

<!DOCTYPE html>

@section(‘main’)
