Trouble with $_GET, isset or something else (?) in a form. I have no idea, this should be really simple.

[Eruondo]

I'm trying to do a form, and in that form, I've put in a little snippet to ensure that my users actually have written something in the fields. I've used these two codes,

if ($_GET['header'] == 0)

{

die( "You did not fill out all forms.");

}

and

if (!isset($_GET['header']))

{

print "You did not fill out all forms.";

}

Bu neither of them works! The first code activates no matter what I write in the header field, and the second one never does... I'm sincerely stuck, and would greately appriciate any help! What am I doing wrong? I'm betting it's something really stupid and easy.

You should post your actual form.

Looking at those 'snippets', they look okay.

Are you sure you're using "$_GET" as the form method?, or are you actually using "$_POST"?

Just do

$length=strlen($_GET['header']);

if ($length == 0)

die ("You must input something");

else

{

code

}

No, it's get. But that code from jon182 fixed it, so thanks! Case closed, :P
