CakePHP object converting to array? - php

Question

I'm trying to display names instead of ids on one of my tables.
I have a WorkRequest which has many WorkRequestChecks of each Checkbox.
These are my table create statements
CREATE TABLE `work_requests` (
`id` int(5) NOT NULL AUTO_INCREMENT,
PRIMARY KEY (`id`)
);
CREATE TABLE `work_request_checks` (
`work_request_id` int(11) NOT NULL,
`checkbox_id` int(11) NOT NULL,
`value` int(3) DEFAULT NULL,
PRIMARY KEY (`work_request_id`,`checkbox_id`)
);
CREATE TABLE `checkboxes` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(45) NOT NULL,
PRIMARY KEY (`id`)
);
From the WorkRequest page I am trying to show a list of WorkRequestChecks that have been entered. This is working fine apart from the fact it seems like cakephp isn't seeing the WorkRequestCheck as an object. It will display the ids of the Checkbox but when I try reference the ->name I get the error.

This is strange as I have this working on WorkRequestChecks index page as displayed below.
This a photo of the errors I get referencing Checkbox name on the WorkRequests page.
This is my code for my WorkRequests view.ctp relating the WorkRequestChecks
<?php foreach ($workRequest->work_request_checks as $Checks): ?>
<tr>
<td><?= $this->Html->link($Checks->checkbox->name, ['controller' => 'Checkboxes', 'action' => 'view', $Checks->checkbox->id])?></td>
<td><?= h($Checks->value) ?></td>
</tr>
<?php endforeach; ?>
I tried printing the $workRequest object and this is the result

}
Then I tried printing on of the $Checks
object(App\Model\Entity\WorkRequestCheck) {
'work_request_id' => (int) 80590,
'checkbox_id' => (int) 1,
'value' => (int) 1,
'[new]' => false,
'[accessible]' => [
'*' => true
],
'[dirty]' => [],
'[original]' => [],
'[virtual]' => [],
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'WorkRequestChecks'
}
This is my WorkRequest controller view method
public function view($id = null)
{
$workRequest = $this->WorkRequests->get($id, [
'contain' => ['WorkRequestChecks']
]);
$this->set('workRequest', $workRequest);
$this->set('_serialize', ['workRequest']);
Here's part of my WorkRequestsTable.php file
public function initialize(array $config)
{
parent::initialize($config);
$this->setTable('work_requests');
$this->setDisplayField('id');
$this->setPrimaryKey('id');
$this->hasMany('WorkRequestChecks', [
'foreignKey' => 'work_request_id'
]);
}
Here's part of my CheckboxesTable.php file
public function initialize(array $config)
{
parent::initialize($config);
$this->setTable('checkboxes');
$this->setDisplayField('name');
$this->setPrimaryKey('id');
$this->belongsTo('CheckboxTypes', [
'foreignKey' => 'checkbox_type_id',
'joinType' => 'INNER'
]);
}
Here's part of my WorkRequestChecksTable.php file
public function initialize(array $config)
{
parent::initialize($config);
$this->setTable('work_request_checks');
$this->setDisplayField('work_request_id');
$this->setPrimaryKey(['work_request_id', 'checkbox_id']);
$this->belongsTo('WorkRequests', [
'foreignKey' => 'work_request_id',
'joinType' => 'INNER'
]);
$this->belongsTo('Checkboxes', [
'foreignKey' => 'checkbox_id',
'joinType' => 'INNER'
]);
}
I'm not sure why this isn't working; it seems like it's converted the object $Check to an array.

Answer 1

As in your CTP, you're trying to access $Checks->checkbox->name
But as your dump says, it contains just:
object(App\Model\Entity\WorkRequestCheck) {
'work_request_id' => (int) 80590,
'checkbox_id' => (int) 1,
'value' => (int) 1,
'[new]' => false,
'[accessible]' => [
'*' => true
],
'[dirty]' => [],
'[original]' => [],
'[virtual]' => [],
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'WorkRequestChecks'
}
So, there is no checkbox field at all and then will always be null and you'll get the error.
You need to associate it in your model if you want to retrieve data from a checkbox with id. Also check the recursive, you might want to change it to 1 or 2.
