Hi,
I have written a custom validator to make either first name or last name
field in my form mandatory. But not both. I have added the custom
validator to the lastName element. The validator won't run unless the
element value is set. I want it to run even though no value is supplied
to the element. Is it possible?
Here's the relevant part of the form:
[snip]
$form = new Zend_Form;
$firstName = $form->createElement('text', 'firstName')
->addValidator(new
Zend_Validate_StringLength(0, 100))
->setLabel('First Name');
$middleName = $form->createElement('text', 'middleName')
->addValidator(new
Zend_Validate_StringLength(0, 100))
->setLabel('Middle Name');
$lastName = $form->createElement('text', 'lastName')
->addValidator(new
Zend_Validate_StringLength(0, 100))
->setLabel('Last Name')
->addValidator(new BV_Validate_PersonName);
[/snip]
Here's the code in BV_Validate_PersonName
[snip]
class BV_Validate_PersonName extends Zend_Validate_Abstract
{
const MSG = 'failed';
protected $_messageTemplates = array(
self::MSG => 'Either first name or last name must be supplied',
);
public function isValid($value, $context = null)
{
$this->_setValue($value);
if (is_array($context)) {
if ( (strlen($context['firstName']) > 1) or
(strlen($context['lastName']) > 1)) {
return true;
}
}
$this->_error(self::MSG);
return false;
}
}
[/snip]
