Hello.

How can I enable/disable form rule using some condition?
Example:

public function rules()
	{
		return array(
			array('email', 'email', 'enable' => app()->param['checkEmail'])
		);
	}

So rule is validated if app->param['cehckEmail'] is true.

Thank you.

Try this

public function rules()
{
  return array(
    array(app()->param['checkEmail']?'email':'', 'email')
  );
}

Edit:
I accidentally modified the attribute instead of the rule specifier. This is what I first intended to do:

public function noRule($attribute,$params) { }

public function rules()
{
  return array(
    array('email', app()->param['checkEmail']?'email':'noRule')
  );
}

I want to validate the field if and only if the field is not empty, how should I do it?

For example, I don't want to put require restriction on the email field, but if it is entered it should be checked for valid email address.

Thanks!

If I understand your question correctly, use the 'email' validator but omit the 'required' validator.

There is magic attribute called allowEmpty

Thank you all of you for your replies!
And if I want to validate the fields which are dependent on values of other fields, how should I do it?

For example, I have a check box for advanced inputs. If user checks it, I need to apply the validation.

Thanks again!

you can always declare custom function in your rules such as:

public function rules()
	{
     return array(
            array('input_field','check'),
  }
}

protected function check()
{
 validate as you wish here and if your application hits into an error just do:
  $this->addError('input_field','error message');
}

hope this helps
