perpage global returning NULL

Posted: Thu Jul 13, 2006 8:58 am

Hi all,

I'm writing a file repository module and having trouble calling the $perpage global.

for example:

Code:

global $perpage;
echo "this is perpage: ".$perpage;

That returns "this is perpage: "

Any ideas? Where is this global stored? Do I need to call another global to get that one to return properly? Thanks!

Are you trying to import the global variable from another page ?

Example:

If page1.php store a value in $perpage and you try to get $perpage value in page2.php, but you haven't included page1.php, this is an error.

Correct Example:

- page1.php -

<?
$perpage = 12345;
?>

- page2.php

<?
include("page1.php");
echo "Perpage: ".$perpage;
?>

_BAD_ Example:

- page1.php -

<?
$perpage = 12345;
echo '<a href="page2.php">Page2</a><br />';
?>

- page2.php -
<?
// global $perpage; <- is useless in this case !
echo "Perpage: ".$perpage;
?>

Bye,
Francesco.
