To delete a record in database, we first need to get hold of a table using the TableRegistry class. We can fetch the instance out of registry using the get() method. The get() method will take the name of the database table as an argument. Now, this new instance is used to get particular record that we want to delete.
Call the get() method with this new instance and pass the primary key to find a record which will be saved in another instance. Use the TableRegistry class’s instance to call the delete method to delete record from database.
Example
Make changes in the config/routes.php file as shown in the following code.
config/routes.php
<?php use CakeCorePlugin;
use CakeRoutingRouteBuilder;
use CakeRoutingRouter;
Router::defaultRouteClass(‘DashedRoute’);
Router::scope(‘/’, function (RouteBuilder $routes) { $routes->connect(‘/users/delete’,
[‘controller’ => ‘Users’, ‘action’ => ‘delete’]); $routes->fallbacks(‘DashedRoute’); });
Plugin::routes();
Create a UsersController.php file at src/Controller/UsersController.php. Copy the following code in the controller file.
src/controller/UsersController.php
<?php namespace AppController;
use AppControllerAppController;
use CakeORMTableRegistry;
use CakeDatasourceConnectionManager;
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’); } } ?>
Just create an empty View file under Users directory called delete.ctp.
src/Template/Users/delete.ctp
Create a directory Users at src/Template, ignore if already created, and under that directory create a View file called index.ctp. Copy the following code in that file.
src/Template/Users/index.ctp
| ID | Username | Password | Edit | Delete |
Execute the above example by visiting the following URL and click on Delete link to delete record.
http://localhost:85/CakePHP/users
