Cakephp validate without saving ()

Question

I am trying to use CakePHP validation without using save() . But it always returns errors. I am inserting text, but the check says it is empty. Why?

My model:

 var $validate = array( 'm_subject' => array( 'empty' => array( 'rule' => 'notEmpty', 'required' => true, 'allowEmpty' => false, 'message' => 'Subject is empty', ) ), 'm_text' => array( 'empty' => array( 'rule' => 'notEmpty', 'required' => true, 'allowEmpty' => false, 'message' => 'Text is empty', ) ) ); 

In my controller:

 $this->Admin->set($this->data); if($this->Admin->validates($this->data, array('m_subject', 'm_text'))) { //OK } else { $errors = $this->Admin->invalidFields(); pr($errors); //Always returns "Subject is empty" and "Text is empty". } 

Answer 1

In CakePHP 2.0 and CakePHP 1.3

$this->ModelName->validates(); does not accept an array of data, if you pass anything to validates() , it is an array of parameters, which is then processed using modelCallback beforeValidates()

Instead, try this logic if you want to determine if the data is valid:

 $this->ModelName->set($this->data); if ($this->ModelName->validates()) { // Data Validated } else { // Data Not Validated } 

Answer 2

thats because you should not use it in this context. it must have these fields present in the $ this-> data otherwise.

read the part about it here: http://www.dereuromark.de/2010/09/21/saving-model-data-and-security/

oh, now i see the problem. you are using validates () incorrectly! you need to set the data first:

 $this->User->set($this->data); $res = $this->User->validates(); 

but this is pretty well documented ...

Answer 3

In a similar note in the CakePHP 2.0 model, there is an option to check only for saveAll ().

validate: set to false to disable validation, true to check each record before saving, “first” to check all records before they are saved (default) or “only” to check only records, but not save them.

Answer 4

Everything looks great. Make sure you create one if you use the cakephp method to create the form

 <?php echo $this->Form->create("Admin"); ?> 

Here "Admin" is the name of the model.

Answer 5

Assign

 $this->data['ModelName']['m_subject'] = $this->data['ModelName']['m_subject']['name'] $this->data['ModelName']['m_text'] = $this->data['ModelName']['m_text']['name'] 

Because

Since loading a file is always an array, it will look like this.

  'm_subject' => array( 'name' => 'foobar', 'size' => 1234567, 'error' => 0, ... ) 

That way, he will always give you an error. Since it is looking for a string and an array found.
