Validating Top Level Domains with Zend 1 - php

Question

I am having a problem with Validating Top Level Domains. Basically, anything with .tech as the TLD is failing the email validation.
I have inherited this project and don't know Zend very well but I have traced the problem back to the hostname not being valid here is the code on GitHub;
// Match hostname part
if ($this->_options['domain']) {
$hostname = $this->_validateHostnamePart();
}
$local = $this->_validateLocalPart();
// If both parts valid, return true
if ($local && $length) {
if (($this->_options['domain'] && $hostname) || !$this->_options['domain']) {
return true;
}
}
return false;
Now, I have some local code here;
class Form_InviteToSpaceForm extends Twitter_Bootstrap_Form_Horizontal
{
public function init()
{
// Set the method for the display form to POST
$this->setMethod('post');
$this->setAction('/team');
$this->addElement('textarea', 'email', array(
'label' => 'Email addresses',
'dimension' => 10,
'required' => true,
'placeholder' => "person1#email.com person2#email.com",//line breaks don't work on placeholders, have to force line wrap with spaces
'filters' => array('StringTrim'),
'validators' => array(
array('validator' => 'NotEmpty'),
array('validator' => 'EmailAddress', 'options' => array('messages' => array('emailAddressInvalidFormat' => 'Incorrect email address specified.')))
)
));
If I comment out the line with the last array('messages' => array('emailAddressInvalidFormat' => 'Incorrect email address specified.'))) then this whole validation is avoided. But I don't want to avoid using this. I just want to be able to extend and add .tech or whatever else comes up from genuine clients. How can I do this with Zend?

Answer 1

You can write custom validator extended from Zend validator
class My_Validate_Hostname extends Zend_Validate_Hostname
{
public function __construct($options = array())
{
parent::__construct($options);
$this->_validTlds = array_merge($this->_validTlds, array('tech'));
}
}
and pass it to email validator
$emailValidator = new Zend_Validate_EmailAddress(array('messages' => array('emailAddressInvalidFormat' => 'Incorrect email address specified.')));
$emailValidator->setHostnameValidator(new My_Validate_Hostname());
....
$this->addElement('textarea', 'email', array(
'label' => 'Email addresses',
'dimension' => 10,
'required' => true,
'placeholder' => "person1#email.com person2#email.com",//line breaks don't work on placeholders, have to force line wrap with spaces
'filters' => array('StringTrim'),
'validators' => array(
array('validator' => 'NotEmpty'),
)
))->addValidator($emailValidator);
