PHP: Form Validation
 

Hey there all. I wanted to know if there was a way to use php to validate form.

Well in more detail, I wanted to know if it was possible to print a msgbox using php telling the user he has missed some thing rather than having to display a new page. Also I don't want to use javascript if possible. Would like to thank in advance.

Of course there is. This is basic PHP. Have you tried to write code for this yet?

Hi,

Whats so bad in displaying the form again? If a input field is empty, you just give it a value like value="Please fill out this field". I think most sites do it like that, and message boxes without JavaScript are hardly possible.

If you wanted to use php functions to do the validation (say against database entries and such), then you might want to consider using an ajax library such as xajax, and make it look spiffy using something like scriptaculous (ok, maybe I'm going overboard, but it can be very slick). I've used that to validate form fields against a database, and point out where issues might exist.

But, you can't really get away from javascript, if you don't want the page to reload. PHP is a server side language, meaning that once the form is rendered and sent to the browser, there's NO link with the server again until you submit back (or use ajax like stuff).

Personally, I prefer just doing client-side javascript validation, as its easier to point out to the user where errors lie. That's not to say that you don't need to revalidate once you hit php, as the javascript side is easily forgeable.
