Question

Alright, so a content page uses this:

$tab = "Friends";
$title = "User Profile"; 
include '(the header file, with nav)';

And the header page has the code:

if ($tab == "Friends") { 
echo '<li id="current">'; 
} else { 
echo '<li>'; 
}

The problem is, that the if $tab == Friends condition is never activated, and no other variables are carried from the the content page, to the header page.

Does anyone know what I’m doing wrong?

Update:
Alright, the problem seemed to disappear when I used ../scripts/filename.php, and only occurred when I used a full URL?

Any ideas why?

Answer 1

Your code as posted should work. How are you actually including that file? Does that happen inside a function? Then you need to use the global statement for it to work. Example:

File 1:

function my_include($file) {
    global $tab; // <-- add this
    include '/some/path/' . $file;
}

$tab = 'Friends';
my_inlcude('file_2.php');

File 2:

if ($tab == 'Friends') { ... }
