[solved] strange Validation problems

Yii 1.1 General Discussion

Hello,

I’m using default Gii Crud and validation to Begin End date attributes like this:


	public function rules()

	{

		return array(

			array('SEnd','compare','compareAttribute'=>'SBeg','operator'=>'>', 'allowEmpty'=>false , 'message'=>'wrong', 'on'=>'create, update'),

			array('SName, SBeg, SEnd', 'required'),

			array('SName', 'length', 'max'=>50),

			array('SComm', 'safe'),

			array('SeaID, SName, SBeg, SEnd, SComm', 'safe', 'on'=>'search'),

		);

	}

Now I noticed that validation is somehow skipped - only rarely it is done and I don’t know the reason why, have you got such a problems? Where could be the reason for skipping compare validation.

[edit]

BTW How to add simple TRIM to entered create form field? I see other frameworks has a build in TRIM function.

I guess it will be locale dependent and may possibly be dependent on the number of characters entered. The standard CCompareValidator just use the inherent operators (==, !=, >, >=, <, <=) on the two operands.

A different approach might be to convert to unix dates in beforeValidate.

Edit:

And of course the most obvious solution is a customized compareDateValidator.

Could You give an example of your possible conversation to Unix date?

Yet another problem:

How to specify TRIM function in Yii style, e.g. entering Name without blank spaces in left/right side (e.g. LTRIM and so on)

Thanks for help in advance!

PHP strtotime() seems to do the job. I’m still working on this so I might reconsider. No need for different locales in my case.




protected function beforeValidate()

{

  ...

  if (!($this->date_in_db = strtotime($this->date_from_view)))

    $this->addError('date_...', 'Bad date');

}

Leave the property for the view in a format suitable for redisplay, in case the validation fails.

There’s a filter validator that can be used with trim().

See the first example here:

Thanks! Solved trimming with Filter:




public function rules()

 {

  return array(

   ...

    array('OName', 'filter', 'filter'=>array($this,'trimmer')),

   ...

  );

}

And custom function:


	

function trimmer($value) 

{ 

 $newValue = trim($value);

 return $newValue; 

}

And about the validation problems, I just removed ‘on’=> params and it works fine now :)

Thanks again, if anyone has something to add you’re welcome!
