Laravel | Delete Records

To delete records we can use DB facade with the delete method. To do so follow the below steps one by one:

Step 1: Create Controller UserController by executing this command.
```
php artisan make:controller UserController
```

Step 2: We can delete records in two ways.

First Method: The first is to delete direct using database command. Write following Code in App/Http/Controllers/UserController.php

<?php 
namespace App\Http\Controllers; 
use Illuminate\Http\Request; 
use DB; 
class UserController extends Controller { 
       public function index()  
       { 
          $users = DB::select('SELECT * FROM users'); 
          return view('user', ['users'=>$users]); 
       } 
       public function destroy($id)  
       { 
          DB::delete('DELETE FROM users WHERE id = ?', [$id]); 
          echo ("User Record deleted successfully."); 
          return redirect()->route('users.index'); 
       } 
} 

Second Method: The second way is to delete using the Laravel delete Function and User Model (Easy one).

<?php 
namespace App\Http\Controllers; 
use Illuminate\Http\Request; 
use App\User; 
class UserController extends Controller { 
       public function index()  
       { 
          $users = User::All(); 
          return view('user', ['users'=>$users]); 
       } 
       public function destroy($id)  
       { 
          $user = User::where('id', $id)->firstorfail()->delete(); 
          echo ("User Record deleted successfully."); 
          return redirect()->route('users.index'); 
       } 
} 

Step 3: Implementation or Driver Code and create web routes for implementation of the above code in routes/web.php
<?php

Route::get('/user', 'UserController@index')->name('users.index');

Route::delete('/user/{id}', 'UserController@destroy')

->name('users.destroy');

?>

Step 4: Create a View File from where we display our users in resources/views directory name user.blade.php. Write following HTML code.

<!DOCTYPE html> 
<html> 
  
<head> 
    <title>Users Record</title> 
    <style type="text/css"> 
        table { 
            color: #333; 
            font-family: sans-serif; 
            width: 640px; 
            border-collapse: collapse; 
            border-spacing: 0; 
        } 
          
        td, 
        th { 
            border: 1px solid #CCC; 
            height: 30px; 
        } 
          
        th { 
            background: #F3F3F3; 
            font-weight: bold; 
        } 
          
        td { 
            background: #FAFAFA; 
            text-align: center; 
        } 
    </style> 
</head> 
  
<body> 
    <table> 
        <tr> 
            <td>ID</td> 
            <td>Name</td> 
            <td>Email</td> 
            <td>Delete</td> 
        </tr> 
        @foreach ($users as $user) 
        <tr> 
            <td>{{ $user->id }}</td> 
            <td>{{ $user->name }}</td> 
            <td>{{ $user->email }}</td> 
            <td><a href="{{ route('users.index') }}" 
                   onclick="event.preventDefault(); 
                    document.getElementById( 
                      'delete-form-{{$user->id}}').submit();"> 
                 Delete  
                </a> 
            </td> 
            <form id="delete-form-{{$user->id}}"  
                  + action="{{route('users.destroy', $user->id)}}" 
                  method="post"> 
                @csrf @method('DELETE') 
            </form> 
        </tr> 
        @endforeach 
    </table> 
</body> 
  
</html> 

Step 5: Start the server by executing php artisan:serve command and go to http://localhost:8000/user and the output will be:
Output: Click on the delete button to get the record deleted. After deleting two records output is:
