Re: Poll of sorts: Javascript Form validation or PHP

Well to reproduce most of that would perhaps be fairly easy, most of it is regex stuff. There may be trouble with the checkdnsrr() stuff though, which is for checking that the domain exists. I wouldn't imagine there would be anything like that for JS... Perhaps there is... You could always do an AJAX request :) On Sun, 7 Dec 2008, tedd wrote:

-snip- I'm impressed. The php routine passed a@x.com (which is real), but failed a@a.com (which is not real). What's needed is a javascript routine to do the same thing, but it would require a trip to the server to check the domain. As such, I would use AJAX to trigger this php routine to provide validation -- that might prove interesting, huh? Apparent real-time validation -- hmmm, I'm going to think about that. The php routine also passed tedd@xn--nvg.com, which is real -- but it's interesting that most email (if not all) programs cannot show the domain name correctly, which is tedd@*.com. I have yet to find an email program that can show IDNS correctly.
