We are getting occasional entries in our custom field input (website URL) that have the http:// but no address. In the earlier thread http://www.gravityhelp.com/forums/topic/custom-input-mask-for-a-valid-url#post-164463 we came up with a function to detect the absence of the http prefix and add it if needed to make it a valid URL and it seems to be working except that now we are getting the occasional prefix only which causes a broken link.
I would like to determine how that prefix is getting there and prevent it? I would be a little surprised if users entered that much and nothing more.
Is there a way to modify the earlier function and force the field to be blank if it only contains the http:// prefix?
