Form Validation

CoB-Himself

I need a script that will look at every field in a form and check to see if it is empty, if it is empty the form then should not be submitted. I need this either in PHP or Javascript. I just have not been able to figure it out. Any help or suggestions?

humm just give each form weget a name then have it submit to the same page or another page and just check the name of the wegets..

example:

index.php

<form name="test_form" method="post" action="submit.php">
<input name="name" type="text" size="15">
<input name="Submit" type="button" value="Submit">
</form>

Submit.php

<?
if ($_REQUEST[name] == "") {
	echo "Sorry you have left the name feild blank!";
} else {
	echo "Name: ".$_REQUEST[name];
}
?>

yeah, that is what I can do.. thanks...

But I wanted it to automatically check all the variables so that I don't have to do every single if statement. maybe have it in a loop or somthing.

why not just do

if ($_REQUEST[name] == "" or $_REQUEST[name2] == "" or $_REQUEST[name3] == "") {

somting like that maybe

and make the form a function so all you do is call the function when theres a form left blank

assuming the form method is POST...

foreach ($_POST as $value)
{
if (!$value) {echo 'You forgot to fill in all fields!';}
break;
}
