Hi guys,
Ok so what I need to do is change the Database name using session.
The admin has to update 2 database, one after another, so I tought of sessions.
But it doesnt work. So here is the code:
Code: Select all
<?php
$ligue = $_GET['ligue'];
function redirect_to($location = NULL) {
if ($location != NULL) {
header("Location: {$location}");
exit;
}
}
function is_connected() {
session_start();
if(isset($_SESSION['logged'])) {
return true;
} else {
redirect_to("/uw-ligues/admin/login.php");
}
}
function setLeague() {
session_start();
$_SESSION['ligue'] = $ligue;
$var = $_SESSION['ligue'];
}
is_connected();
setLeague();
if($var != "") {
$chosed = $var;
} else {
$chosed = "ligue1";
}
echo "Ligue: $chosed<br/>";
$link = mysql_connect ("localhost", "user", "pass")or die("mysql_error()");
mysql_select_db ("DB_$chosed", $link)or die("mysql_error()");
?>
So, as you guessed it, the $ligue is sent trought a GET variable from a previous link.

i am having problems with sessions too. In Aravinthan's case id say it was because he didnt use session_start(); before hand, but for me i am using it and my session variables are all not set and empty.

Hi,
Thanks for your help, but still nothing...
Oh and I forgot to mention that I get this warning:
Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively in Unknown on line 0
But no, it still keeps ligue1, instead of switching it to ligue2

this didn't help me. here is how I am initializing the session variables.
Code: Select all
foreach ($row as $val)
{
$_SESSION[$rowcount] = $val;
// echo "<td>$val</td>\n";
$rowcount=$rowcount+1;
}
they should be set because i checked them later on from the same php page. after the new web page loads all of the session variables are just not set. Should i be using post and get like Aravinthan? if there is an easier way to pass variables between pages id love to hear them.

It took the warning away,
But it still doesnt switch the session variables....
Here is the page I use to set the datas for the $GET:
Code: Select all
<?php
include("fichiers/connection.php");
include("style/header.php");
echo "Admin Cpanel</br>";
echo "1- <a href='fichiers/index.php?ligue=ligue1'>Ligue 1</a><br/>";
echo "2- <a href='fichiers/index.php?ligue=ligue2'>Ligue 2</a><br/>";
include("style/footer.php");
?>
