Depends what kind of information needs to be validated. Does it simply just need to check everything is filled in, does it need to check for valid email address, etc.

Look at the function empty (http://www.php.net/manual/en/function.empty.php) or isset (http://www.php.net/manual/en/function.isset.php). That should do the trick :)

Thows are good but how do i keep the form from submitting ?

You have your HTML form that post's (the form method) the data to your PHP script. For example:


<?php
// We'll say that there's only 2 fields from the form that we posted to this script, the names of the fileds were "name" for their first name, and "lname" for their last name.


// get the values form the form
$name = $_POST['name'];
$lname = $_POST['lname'];

// below is read like "if name or lname (or both) is NOT set (hense the '!' at the beginning) then...
if(!(isset($name) || isset($lname)) {
echo "Please fill out the entire form.";
}

else {
// if everything is filled in, then the code here will be run
}
?>

Did that help?

You still need to validate the form afterwards in PHP though. Javascript can either be turned off or not supported by the browser and they could submit invalid data that way.

CareBear's right. For simple validation like the one you want, it's probably easier to use Javascript so the user doesn't have to go to the next page, hit the back button etc. But then CareBear's right again, you'll still have to check it in PHP because some browsers may have Javascript turned off.

CareBear = Right :D

Check out NuSphere's PHPed (http://phped.com), its exspensive, but its supposed to be really good. You can download the trial though, I did. I "so-so" liked it.. Lests just say its uninstalled now ;)
