CakePHP - Validation errors displayed twice - php

Question

I am using CakePHP 2.10.19. I have a form for entering Item Types. I also have other models for entering appropriate database objects. Error I am occurring is that my validation errors are displayed twice for this form. For other forms it works well. Here is the model:
ItemType.php
App::uses('AppModel', 'Model');
class ItemType extends AppModel {
public $classes = array(
'product' => 'Proizvod',
'kit' => 'Kit (bundle)',
'material' => 'Repromaterijal'
);
public $validate = array(
'code' => array(
'required' => array(
'rule' => 'notBlank',
'message' => 'A code is required'
),
'alphanum' => array(
'rule' => 'alphanumeric',
'message' => 'A code must be an alphanumeric value'
),
'unique' => array(
'rule' => 'isUnique',
'message' => 'This code already exists!'
),
'between' => array(
'rule' => array('lengthBetween', 3, 7),
'message' => 'Code must be between 3 and 7 characters long'
)
),
'name' => array(
'required' => array(
'rule' => 'notBlank',
'message' => 'A name is required'
),
'unique' => array(
'rule' => 'isUnique',
'message' => 'This name already exists!'
),
'between' => array(
'rule' => array('lengthBetween', 3, 30),
'message' => 'Name must be between 3 and 30 characters long'
)
),
'class' => array(
'valid' => array(
'rule' => array('inList', array('product', 'material', 'kit', 'semi_product', 'service_product', 'service_supplier','consumable','inventory','goods','other')),
'message' => 'Please enter a valid class',
'allowEmpty' => false
)
),
'tangible' => array(
'bool' => array(
'rule' => 'boolean',
'message' => 'Incorrect value for the checkbox'
)
),
'active' => array(
'bool' => array(
'rule' => 'boolean',
'message' => 'Incorrect value for the checkbox'
)
)
);
public $hasMany = array(
'Item' => array(
'className' => 'Item',
'foreignKey' => 'item_type_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);
}
ItemTypesController.php
<?php
class ItemTypesController extends AppController {
public function add() {
if ($this->request->is('post')) {
$this->ItemType->set($this->request->data);
if($this->ItemType->validates()){
debug($this->ItemType->validates());
$this->ItemType->create();
if ($this->ItemType->save($this->request->data)) {
$this->Flash->success(__('The item type has been saved.'));
return $this->redirect(array('action' => 'index'));
} else {
debug($this->ItemType->invalidFields());
$this->Flash->error(__('The item type could not be saved. Please, try again.'));
}
}
debug($this->ItemType->invalidFields());
$this->Flash->warning($this->ItemType->validationErrors, array(
'key' => 'negative'
));
}
$this->set('classes', $this->ItemType->classes);
}
}
Also, debug($this->ItemType->invalidFields()) is showing array with two fields for each field, like this:
array(
'code' => array(
(int) 0 => 'Code must be between 3 and 7 characters long',
(int) 1 => 'Code must be between 3 and 7 characters long'
),
'name' => array(
(int) 0 => 'Name must be between 3 and 30 characters long',
(int) 1 => 'Name must be between 3 and 30 characters long'
)
)
...so I am guessing a model is making some sort of mistake.
add.ctp
<div class="itemTypes form">
<?php echo $this->Form->create('ItemType'); ?>
<fieldset>
<legend><?php echo __('Add Item Type'); ?></legend>
<?php
echo $this->Form->input('code');
echo $this->Form->input('name');
echo $this->Form->input('class', array('options' => $classes));
echo $this->Form->input('tangible');
echo $this->Form->input('active');
?>
</fieldset>
<?php echo $this->Form->end(__('Submit')); ?>
Anyone has an idea. Thing is, other controllers have basically the same logic but do not have this sort of a mistake where validation errors are displayed twice.

Answer 1

Generally this is because validation is triggered twice. This is triggered twice, once when you call $this->ItemType->validates()) and another time when you call debug($this->ItemType->invalidFields());
Please comment and remove all the debug statements.

Answer 2

Apparently upon removing the debug statements it works like it should with only one validation error per type as it should do. Not sure why debug made problem tho.
