This tutorial will show how to create a bulk delete function in CakePHP 4. The bulk delete is a process of selecting a group of records in a single table and removing it from the database. A checkbox will be rendered on each of the record IDs and sent to the function that manages the delete all process.
Create Checkbox
A checkbox is used to capture the id of each selected record that need to be deleted. The checkbox is generated in the index page as shown below:
<table id="main_index" class="table table-hover text-nowrap">
<thead>
<tr>
<th><?= $this->Paginator->sort('#') ?></th>
...other codes
<?= $this->Form->create(null,['url'=>['action'=>'bulkDelete']]) ?>
<?php foreach ($users as $user): ?>
<tr>
<td><?= $this->Form->checkbox('ids[]',['value'=>$user->id]) ?></td>
</table>
<button class="button">Delete Selected</button>
<?= $this->Form->end() ?>
<?= $this->fetch('postLink'); ?>Public Function bulk delete
Create the public function that handles the bulk delete process as shown below in your controller.
public function bulkDelete()
{
$this->request->allowMethod(['post','delete']);
$ids = $this->request->getData('ids');
if($this->Users->bulkDelete(['Users.id IN'=>$ids])){
$this->Flash->success(__('The selected user has been deleted.'));
} else {
$this->Flash->error(__('Please select user to delete'));
}
return $this->redirect(['action' => 'index']);
//exit('test');
}Now you should be able to select and delete the records.
If you want to have a main checkbox in your header that will select all or deselect all the checkboxes with one single click, use this code in your header:
<th><?= $this->Form->checkbox('ids[]',['onchange'=>'checkAll(this)', 'name'=>'chk[]']) ?></th>Then add the following script at the end of your code:
<script>
function checkAll(ele) {
var checkboxes = document.getElementsByTagName('input');
if (ele.checked) {
for (var i = 0; i < checkboxes.length; i++) {
if (checkboxes[i].type == 'checkbox') {
checkboxes[i].checked = true;
}
}
} else {
for (var i = 0; i < checkboxes.length; i++) {
console.log(i)
if (checkboxes[i].type == 'checkbox') {
checkboxes[i].checked = false;
}
}
}
}
</script>That all. Happy coding :)
