这是field_validation.validators.inc文件的：
<?php

return array(

'custom_data' => array(
'label' => t('Regex code'),
'description' => t('Specify regex code to validate the user input against.'),
),
'description' => t("Validates user-entered text against a specified regular expression. Note: don't include delimiters such as /."),
),
);
}
/**

function field_validation_field_validation_validate($validator_name, $items, $rule) {
if ($items) {
$error = array();
switch ($validator_name) {
case "regex":
mb_regex_encoding('UTF-8');
$regex = $rule['data'];
foreach ($items as $delta => $item) {

//debug($errors);
}
}
return $error;
break;
}
}
}

/**

这个文件里面，我知道的好像只有field_validation_field_validation_validators，field_validation_field_validation_validate，field_validation_get_validators是有用的。其它的大部分都是特定于webform_validation的，当时是一股脑的复制了过来的，然后一个一个的字符串替换。我们看到这里保留了大量的webform_validation的信息。
