Question

I have this problem. Session does not work when I use with $_POST. If I add 63 manualy it will works across pages. I can see the output 63.

$_SESSION['name'] = 63;
echo $_SESSION['name'] ;

but this below won’t work when I switch between pages. The $row[‘id’] output is also 63.

$cari = "SELECT  id FROM dns_soa WHERE `origin` = '".$_POST['origin']."'";
$keputusan = mysql_query($cari);

$row = mysql_fetch_array($keputusan);   

$_SESSION['name'] = $row['id'];
echo $_SESSION['name'] ;

When I go to 2nd pages I can see the output but when I went back to 1st pages the output is gone. Any idea?

Answer 1

Because when you are coming back it will again set the session variable, as this time you don’t have the $_POST[origin] variable that leads to $row[‘id’]=”” and the session variable also NULL…

What you should do is..

$cari = "SELECT  id FROM dns_soa WHERE `origin` = '".$_POST['origin']."'";
$keputusan = mysql_query($cari);

$row = mysql_fetch_array($keputusan);   

if(!isset($_SESSION['name']))
    $_SESSION['name'] = $row['id'];

echo $_SESSION['name'] ;
