Hello everyone,

I'm currently working on a site that has a ComplexTableField with a field for adding links. What I would like is for people to put a url in here and for it to add in the http:// prefix if it hasn't already been entered.

Is there a specific field type for the back end that will do this for me?

public function onBeforeWrite() {
		$url = $this->Website;
		if($url) {
			if(substr($url, 0, 8) != 'https://') {
				if(substr($url, 0, 7) != 'http://') {
					$url = $this->Website = 'http://' . $url;
		$this->Website = strtolower($url);

Thanks Martijn,

I thought there may have been a specific field type that would deal with it but your replacement is perfect!

This may be more useful:

	function setWebsite($URL) {
		if (!$URL || !trim($URL)) return $this->setField('Website','');

		if (!preg_match('/^https?:\/\//i',$URL)) {
			$URL = 'http://'.$URL;
		return $this->setField('Website',$URL);

This will be processed any time $Object->Website = "something" occurs.

I purposefully didn't include strtolower. URLs ARE case sensitive (though domains and protocols are not).
