Thread: How do I validate a URL?

And what is proper image url?
image34534534534534
image.php?gen=23423423423
/image/7234273642734
image.jpg -> rewrite hack.pl

I figured it out, thanks anyway.

Hi Bulletproof

I'm also trying to validate a URL. How did you do it?

I need to validate URLs like:

Code:

http://www.websites.com
http://subdomain.websites.com
http://www.websites.com/directory/
http://www.websites.com/index.php?whatever=xyz

I've tried using Hostname, but it fails on any URLs with a directory.

Thanks

You can validate a URI using Zend_Uri but it doesn't implement the Zend_Validate_Interface. So, you'll have to roll your own. Fortunately, it's pretty easy to do so:

[PHP]
class Url_Validator extends Zend_Validate_Abstract
{
const INVALID_URL = 'invalidUrl';

protected $_messageTemplates = array(
self::INVALID_URL => "'%value%' is not a valid URL.",
);

public function isValid($value)
{
$valueString = (string) $value;
$this->_setValue($valueString);

if (!Zend_Uri::check($value)) {
$this->_error(self::INVALID_URL);
return false;
}
return true;
}
}

// When creating the form:
$website = $form->createElement('text', 'website');
$website->addValidator(new Url_Validator);
[/PHP]

Hope that helps

nice! that works pretty well. thanks

How about just passing a REGEX to the validator as an alternative:
