form validation rule "valid_url" not working as expected. here is my code

PHP Code:

$this->form_validation->set_rules('website', 'Website', 'required|valid_url'); 


this rule returning true for string "test" for following markup

PHP Code:

<input type="text" class="form-control" id="website" name="website" placeholder="Website Address" required/>

There is already a question like this one on the forum: http://forum.codeigniter.com/thread-6173...=valid_url

[rejoan]

any string treating as valid. "test","spinytel", "rejoan" all are tested. returning true & form submitting

[Avenirer]

well... localhost is also a valid url, isn't it?

...because those are valid URLs. Try using a character which is not permitted in a URL, or an invalid structure for the URL. I'm not sure how good the validation is, but I'm sure that your examples so far have all been valid URLs.

You're clearly looking for a validation which does something else, probably more explicit than simply determining whether it is a valid URL.

In fact i need a rules which will return true only when find URL like these "google.com", "www.google.com", "http://google.com" etc but return false when not a valid a web address

Your best bet in this case would probably be to create a custom validation function which calls the valid_url() method, then performs additional checks if the valid_url() method returns true.

The first resource for determining what makes up a valid URL is often RFC 3986, but I don't think you'll find this very helpful for whatever you need to do to determine what input represents a "valid web address".
