Show region when link clicked

[d34db0lts]

i would like to show a region after a link has been clicked. thus far, i have this:

<a href="main.php?adduser=true">Add User</a>
<?php if ($_GET['adduser'] == "true") { // Show form is link clicked ?>
you want to add a user...how nice.
<?php } // Show form is link clicked ?>

when i click the link, it shows "you want to add a user....how nice." but when i go to main.php, it shows this error:

Notice: Undefined index: adduser in c:\easyphp1-7\www\awesomewebsite\admin\main.php on line 31

line 31 is the one that has the $_GEt function.

i'm sure there are other ways to do this. what i really want to do is when the link "add user" is clicked, to show a form with text boxes and all so that the user can add users.

please....someone help me!!!!!!!!

i will love you forever!

Be a lot easier if you posted more script. Still, page1 has the link, and main.php is to diplay the form, yes?

// in main.php
if ($_GET['adduser'] == 'true') {
 echo '<form>';
 // etc 

}

Very simple example

still get the error.

i didn't post more code because it is not necessary.

thanks for helping though...i think i might just go with some css instead of using php.

That's because when you first enter the page $_GET['adduser'] is not defined.

You should write:
<?php if (isset($GET['adduser']) && $GET['adduser'] == "true") {
instead
