How to delete data from database using CakePHP framework


In this example we will discuss about how to delete a record or data from MySQL database using CakePHP framework PHP.

The DELETE statement is used to delete records from a table:

DELETE FROM table_name
WHERE some_column = some_value

Notice : The WHERE clause specifies which record or records that should be deleted. If you omit the WHERE clause, all records will be deleted!

The students table look like this:

id first name last name City name Email Id Action
1 Divyasundar Sahu Mumbai [email protected] Delete
2 Hritika Sahu Pune [email protected] Delete
3 Milan Jena Chennai [email protected] Delete

Now i am going to delete the id=3 record.

For delete record we use 4 file here

  1. routes.php (config/routes.php )
  2. UsersController.php (src/controller/UsersController.php)
  3. delete.ctp (src/Template/Users/delete.ctp)
  4. index.php (src/controller/index.php)

config/routes.php

<?php
use Cake\Core\Plugin;
use Cake\Routing\RouteBuilder;
use Cake\Routing\Router;
Router::defaultRouteClass('DashedRoute');
Router::scope('/', function (RouteBuilder $routes) {
$routes->connect('/users/delete', ['controller' => 'Users', 'action' => 'delete']);
$routes->fallbacks('DashedRoute');
});
Plugin::routes();

src/controller/UsersController.php

<?php namespace App\Controller; use App\Controller\AppController; use Cake\ORM\TableRegistry; use Cake\Datasource\ConnectionManager; class UsersController extends AppController{ public function index(){ $users = TableRegistry::get('users'); $query = $users->find(); $this->set('results',$query); } public function delete($id){ $users_table = TableRegistry::get('users'); $users = $users_table->get($id); $users_table->delete($users); echo "User deleted successfully."; $this->setAction('index'); } } ?>

Now just create an empty View file under Users directory called delete.ctp.

index.ctp

<!DOCTYPE html>
<html>
<body>
<table border="1">
<thead>
<th>Id</th>
<th>First name</th>
<th>Last name</th>
<th>City name</th>
<th>Email</th>
<th>Action</th>
</thead>
<tbody>
<?php
foreach($this->a->fetchtable() as $row)
{
?>
<tr>
<td><?php echo $row->id ; ?></td>
<td><?php echo $row->first_name; ?></td>
<td><?php echo $row->last_name; ?></td>
<td><?php echo $row->city_name; ?></td>
<td><?php
$id=$row->id;
echo $row->email; ?></td>
<td><a href=<?php echo site_url('student_delete/deletedata/'.$id);?>>Delete</a></td>
</tr>
<?php
}
?>
</tbody>
</table>
</body>
</html>

After delete the record the table look like this.

id first name last name City name Email Id Action
1 Divyasundar Sahu Mumbai [email protected] Delete
2 Hritika Sahu Pune [email protected] Delete
