determine if a page is active and unlink the link if so

[joeliahhh]

Hi! For some reason this script doesn't work.. but why nott??

<?php
$indexac = '/home/.(etc)./index.php';

if ($indexac == 'index.php')
{
echo '<div>Home</div>';
}
else
{
echo '<a href="index.php">Home</a>';
}
?>

It should unlink the button of the page which is currently visited.. can you maybe see a reason what's wrong about it? Thanks!

I think this will do what you want:

$indexac = '/home/.(etc)./index.php';
$current_page = $_SERVER['SCRIPT_FILENAME'];
if ($current_page == $indexac) { 
    echo '<div>Home</div>'; 
} else { 
    echo '<a href="index.php">Home</a>'; 
}

hmm, I tried this out, but it still isn't working.. maybe I should use basename() or getenv()? I really wonder what's wrong with it! Thanks anyway for your suggestion!

If that doesn't work, and the home page is "index.php" which is in your doc root, then you have the wrong value for $indexac. This will work:

$indexac = $_SERVER['DOCUMENT_ROOT'] . '/index.php';

sorry, I'm such a noob 🙁

Ok, so to make it clear.. I have:

<?php
$indexac = '/home/julia/public_html/persoonlijk2/index.php';
$indexact = '/persoonlijk2/index.php';
if ($indexac == $indexact)
{
echo '<div>Home</div>';
}
else
{
echo '<a href="index.php">Home</a>';
}
?>

Though it also doesn't work 😢
What confuses me is that I found:

DOCUMENT_ROOT /home/user/webroot/
SCRIPT_NAME /home/user/webroot/folder/file.php
SCRIPT_FILENAME /folder/file.php
REQUEST_URI /folder/file.php?argument=value
(https://panel.dreamhost.com/kbase/index.cgi?area=2933)

though I always thought that DOCUMENT_ROOT was the whole path
