Silent validation

Yii 1.1 General Discussion

Hi,

Is there any way to do $model->validate() without having errors added? I just want to know the true og false value, but not add errors as the user may not even have entered data yet.

Thanks.

You could call $model->validate() and then $model->clearErrors() before the form is redisplayed.

I know, but if the code is executed after a real validation of user input, the errors shouldn’t be cleared.

You could write a function in your model, or a component if you’ll need it across the entire app, to validate and then clean errors.




    public function isValid()

    {

        $isValid = false;

        

        if ($this->validate())

            $isValid = true;

        

        $this->clearErrors();

        

        return $isValid;

    }

I dont’ think you understand the problem. I can’t do “clearErrors()”, because their may be data there.

Would this work?




    public function isValid()

    {

        $errors  = $this->getErrors();


        $isValid = false;

        

        if ($this->validate())

            $isValid = true;

        

        $this->clearErrors();


        // Psuedo foreach $errors : $this->addError($error);

        

        return $isValid;

    }

Yes it would, but is is not that elegant.

You might also want to look into beforeValidate and afterValidate

What solution did you decide to go with? Mind sharing?

I haven’t implemented a solution yet. I still think the only way to really do this, is support a silent parameter in CActiveRecord::validate.

I don’t understand your need… you want to validate but not to display error… and at the same time you want to display error is there is some data…

can you explain a bit more… when would you like to validate but not display errors… and when would you like to validate and display errors…
