Cakephp Website URL input validation

Question

I tried some regular expressions for website URL validation that only accept URLs starting with www. (not http:// or https://), but none fit my needs.

I tried : (?<!:\/\/)www\..+\.[a-z]{2,3} but that accepts URLs with other characters before www., like adswww.website.com. I only want to accept URLs that start with www..
