Anyone who has tried to validate a user input using Zend_Validate_EmailAddress will find that there are a LOT of error messages returned – one for each problem with the email address:

  • Invalid format
  • Invalid hostname
  • Invalid mx record
  • and 5 more

This class will replaces all the error messages with one message.

Solution

<?php

/**
 * Override Zend_Validate_EmailAddress so that only one error message shows when there is a problem
 */
class RPK_Validate_EmailAddress extends Zend_Validate_EmailAddress
{

  /**
   * Returns true if and only if $value is a valid email address
   * according to RFC2822
   * @param string $value
   * @return boolean
   */
  public function isValid($value)
  {
    $response = parent::isValid($value);
    if (!$response)
    {
      $this->_messages =
        array(self::INVALID => "Please enter a valid email address");
    }
    return $response;
  }
}

Useage

<?php
//in form object
$element->addValidator(new RPK_Validate_EmailAddress());
