Valid url check in form validation

[quote author="Mike Ryan" date="1239399749"]Hi Iverson,

Great contribution, I have always been a little surprised that this function was not included as a built-in rule. [/quote]

Look at line 7 in system/language/english/form_validation_lang.php :

Code:

$lang['valid_url']             = "The %s field must contain a valid URL.";

And yet, you're right, I can't see a valid_url() function in the form_validation library. Maybe I'm missing something, or maybe someone was planning to create a valid_url() validation function and, err, forgot? :coolsmirk:
