check on model if 2 fields have the same value

Yii 1.1 General Discussion

Hi,

I have 2 fields (person1, person2)

I want to check on rules if the person1 is equal person2.

I tried something like that:

Added on rules




array('id_person1', 'same', $this->id_person2),

Created a method




	public function same($attribute,$params)

	{

	    if($this->$attribute == $params)

	      $this->addError($attribute, 'You cannot set the same responsavel');

	}

but it dont work, i don’t know how to create that validation.

Someone can help me.

I can do that in the controller, but i think it’s more correct to do that on the model.

Thanks

Look at the ‘compare’ validator. Already built.

But i want to check it on the create/update not on the search.

I need to validate it on the form, how i add a rule to check it using compare?

I believe waitforit meant this (see also here), and not the CDbCriteria compare method.

And maybe see this wiki.
