Validator Code:
<?php
class Validator_NoRecordExists extends Zend_Validate_Abstract
{
private $_table;
private $_field;
const OK = '';
protected $_messageTemplates = array(
self::OK => "'%value%' allready in database"
);
public function __construct($table, $field) {
if(is_null(Doctrine::getTable($table)))
return null;
if(!Doctrine::getTable($table)->hasColumn($field))
return null;
$this->_table = Doctrine::getTable($table);
$this->_field = $field;
}
public function isValid($value)
{
$this->_setValue($value);
$funcName = 'findBy' . $this->_field;
if(count($this->_table->$funcName($value))>0) {
$this->_error();
return false;
}
return true;
}
}
Use like:
$this->addElement('text', 'username', array(
'validators' => array(
array(
'validator' => new Validator_NoRecordExists('User','username')
)
)
));
