I

How do i validate url adress. I just cant get i to work.

I need to check that there is "http://" and "som tekst" and ".some text"

Hi there, best thing to do would be to use a regular expression. Try this one:

if(preg_match("#^http://[a-zA-Z0-9\\-\\.]+\\.[a-zA-Z]{2,5}#", $_POST['url'])) {

		echo "<h1>VALID!</h1>";
	} else {

		echo "<h1>INVALID!</h1>";
	}

If you need it explained, gimme a yell I'll be more than happy to help!

I'm using the code you made, bit i cant even get it og pass a valid url now 🙂

if($password != "")
{
if(!ereg("#^{[url]http://[/url][a-zA-Z0-9-.]+.[a-zA-Z]{2,5}#",} $homepage))
{
$errorMsg = "Fejl: dohhhhhhhhh!";
$errors = "TRUE";
}
}

Just need to check if theres a [url]http://[/url] and if there is a .somthing at the end

That's because you're using the ereg function, not the preg_match. They're different types of regular expressions. What I gave you was Perl Compatible, so you need to use preg_match. If you want to use ereg, you'd need this expression.

^{[url]http://[/url][a-zA-Z0-9.-]+.[a-zA-Z]{2,5}}

Not much different for something like this, except that it doesn't have the delimiters on the start and end.

I would suggest using preg_match, as it's more efficient.
