What in gods name is wrong

[PyroX]

if($_GET['sort']!=''){
        if($_SESSION['mysort']!=$_GET['sort']){

    $sql.= " $sort ASC";
    $_SESSION['mysort']=$sort;

    } else {

    $sql.= " $sort DESC";
    $_SESSION['mysort']=null;

    }

} else {
$sql.= " id ASC";
}

No matter what the $SESSION['mysort'] is always blank. If I output it after the if statments it is loaded, but on the next page its always blank. The session ALREADY CONTAINS other data that is being saved propely. So the session is working. Its like it ALWAYS evaluates the SESSION['mysort']=null; even when not logically codewise possible.

What the heck?

I am frustrated as hell.

if($_GET['sort']!=''){
        if($_SESSION['mysort']!=$_GET['sort']){

    $sql.= " $sort ASC";
    $_SESSION['mysort']=$sort;

    } else {

    $sql.= " $sort DESC";

    }

} else {
$sql.= " id ASC";
}

When I use it like this, it works 1/2 way, it does set the mysort, and if the next sort button clicked is the same, it sets it DESC, but of course after that it wont let it go back to ASC.

Here is another way:

$SRT = $_GET['sort'];

echo $_SESSION['DOSORTINGBY'].' ';

if($SRT!=''){

    if($_SESSION['DOSORTINGBY']==$SRT){

    $sql.=" $SRT ASC";
    $SRT="none";

    } else {

    $sql.=" $SRT DESC";

    }

} else {
$sql.= " id ASC";
}

$_SESSION['DOSORTINGBY']=$SRT;
echo $_SESSION['DOSORTINGBY'];

In this example, the output is ALWAYS:

none lname
none email

etc

So its like it just does not care that I did $_SESSION['DOSORTINGBY']=$SRT;

The session does not actually save it.
