Validating Input Box

[PaulSonny]

Hello Everybody,

I am struggling with this and would appreicate some help.

I have an input box, named title.

I want it to display an error message and re-direct to the previous page to enter a title if the title input box has no title.

I've tried a few different things and nothing works.

ANy help?

Thanks, Paul.

vBulletin has a standard redirect you could use, however it is not equivalent to the back button. Using this method, you will loose the values your user previously set unless you forward them into the next page:

$url = "http://www.yoursiteurl.com/yourscript.php";
standard_redirect("Redirect Message.",$url);

You might instead choose to use JavaScript to validate the form and pop up an alert if the title box is empty.
