How to Delete data in database using PHP MVC with example


In this example we using Models, Views, Controller Structure for Delete the inserted data.

To Delete data in the database first we have to create a Controller file.

controller/index.php

<?php

class Index extends Controller {

	function __construct() {
		parent::__construct();
	}
	
	function index() {
	
		$this->view->allrecords = $this->model->getAllrecords();
		$this->view->render('index/index');
		
	}
	
	
 function delete_index($id) 
	{
		
		$this->model->delete_index($id);
		header('location: ../index/index');
	}
}

Here is the model file which we are using for Delete data from database.

The file index_model.php is created under Models folder

models/index_model.php

index_model.php

<?php

class Index_Model extends Model
{
	public function __construct()
	{
		parent::__construct();
	}

	public function getAllrecords()
	{
		return $this->db->select("SELECT * FROM `mvc` ORDER BY id DESC");
	}
	public function delete_index($id)   
	{
		$this->db->delete('mvc', "`id` = {$id}");
		
	}
}

Here is the view file index.php which inside views folder contains the table

views/index/index.php



		<table border="2" id="internalActivities" style="width:100%" class="table table-bordered">
		
                     <tr>
                       
                       
                       <th>Name</th>
					   <th>Email</th>
						<th>contact</th>
					   
					   <th></th>
								   
                     </tr>
	<?php foreach($this->allrecords AS $key=>$value){
			?>
				 <tr>

				   
				   <td><?php echo $value['name']."<br>"?></td>
				   <td><?php echo $value['email']."<br>"?></td>
					<td><?php echo$value['contact'];?></a>
					</td>
												
											  
 <td><a href="javascript:confirmDelete('delete_index/<?php echo $value['id'];?>')" class="btn btn-primary btn-sm" role="button">Delete</a></td>
											    
											
					<?php } ?>
</table>	

           <script>
function confirmDelete(delUrl) {
  if (confirm("Are you sure you want to delete")) {
    document.location = delUrl;
  }
}
</script>
