From a page that usually display in a frame I have this JS :
if (self == top) { top.location.href="/index.php?url=test.php"; }
Now you may have guessed what I'm trying to do, load the top page but
with the frame I passed in the URL
I successfully achieved my goal with JS but I think it would be nice
using PHP.
How can I extract only "test.php" from the URL so I can:
<?php echo "<iframe src=\'" + url + "'>" ?>
Thanks
Look at the $_GET superglobal.

Found it, thanks for the clue!

I'm no php expert and even if the next line works, maybe someone can
optimize it?

<iframe src="<?php if ($_GET["url"] == "") { echo "default.php"; }
else { echo $_GET["url"]; } ?>"></iframe>

What you have is fairly optimized however it is not secure. people could use this to load url's that you are not wanting.

What I suggest is something like
<?php
// if url is set assign $url the url else set it to default
$url = isset($_GET['url']) ? $_GET['url'] : 'default.php';

$ok_url="default.php"; // set default ok_url
switch ($url)
{
case 'first.php' : $ok_url="first.php";break;
case 'second.php' :$ok_url="second.php";break;
case 'third.php' :$ok_url="third.php";break;
}

print '<iframe src="'.$ok_url.'"></iframe>';
?>

This way you have TOTAL control on what happens.
( there are other ways to do this but that is the quickest i could think of )
