Question

I have a Zend_Form_element:

$text=new Zend_Form_Element_Text('text');

I added a regex validator to it:

$text->addValidator('regex', false, array('/[\\?\\&]v=([^\\?\\&]+)/'));

How could I set a customized error message for the validator?

Answer 1

You can add custom validation error messages if you know what specific error codes the validator provides. In case of regex, I believe it gives an “regexNotMatch” error, so for this particular case, you could use:

$text->addValidator('regex', false, array(
    '/[\\?\\&]v=([^\\?\\&]+)/',
    'messages'=>array(
    'regexNotMatch'=>'There was some random custom error'
    )    
));

For more information, have a look here.

Some developers may wish to provide custom error messages for a validator. The $options argument of the Zend_Form_Element::addValidator() method allows you to do so by providing the key ‘messages’ and mapping it to an array of key/value pairs for setting the message templates. You will need to know the error codes of the various validation error types for the particular validator
