hi folks,

i started developting a database application using the xoops-framework with PEAR and MySQL within the XOOPS-mypage-module.

things worked fine until i run into this problem: imagine you have to views on a content namely A.php and B.php, which are calling a detail page C.php for editing. when editing is done C shall return to it's caller, which could be A or B.

how can i relize such a behaviour? i've already tried a session-stack approach without to much success, since XOOPS seems to kill my variables.

any usefull piece of advice is more than welcome...

desperately

XOOPS doesn't kill variables, so could you be a little more specific on what your approach is?

Add a variable in the URL could perhaps be another approach?

sorry, for beeing that general. here is the piece of code i'd like to use:

<?php
if(!session_id()){
session_start();
}

if (!isset($_SESSION['stack'])) {
$stack = array();
$_SESSION['stack'] = $stack;
}

function push($src) {
$stack = $_SESSION['stack'];
$stack[] = $src;
$_SESSION['stack'] = $stack;
}

function pop() {
return array_pop($_SESSION['stack']);
}

if (!isset($_SESSION['previous'])) {
echo "no prev<br>";
}
if (!isset($_SESSION['current'])) {
echo "no curr<br>";
}

echo "PREV:" . $_SESSION['previous'] . "<br>";
echo "CURR:" . $_SESSION['current'] . "<br>";

$_SESSION['previous'] = (string) $_SESSION['current'];
$_SESSION['current'] = (string) $_SERVER['PHP_SELF'] . ($_SERVER['QUERY_STRING'] ? "?" . $_SERVER['QUERY_STRING'] : "");

if ($_SESSION['current'] == $_SESSION['previous']) {
echo "POP<br>";
pop();
$_SESSION['previous'] = end($_SESSION['stack']);
} else {
echo "PUSH<br>";
push($_SESSION['previous']);
}
?>

this file shall be inlcuded in every page. but while debugging this, the session variables where gone till the next page was displayed.

thanx!
