[mythtv-users] mythweb Recorded Programs Warning sorting.php line 42

[Andy Whitworth]

I put in an if statement to only perform the foreach statement
if the $_SESSION[....]  variable was set....

See "MY MOD START/END" comments to see my inserted line.

    function sort_status($field, $session = NULL) {
    // Null session means to load the last sorted session
        if (!$session)
            $session = $GLOBALS['last_sort_session'];
    // Make sure the field is lower case
        $field = strtolower($field);
    // No sort function for this variable
        if (!function_exists("by_$field"))
            return NULL;
    // Scan the sort array for any entries matching the current
choice, and remove them
        $depth = 0;
// MY MOD START
         if (!isset ( $_SESSION[$session] ) return false;
// MY MOD END
        foreach ($_SESSION[$session] as $key => $sort) {
            $depth++;
        // No match, continue looking
            if ($sort['field'] != $field)
                continue;
        // What to do now...
            return ($sort['reverse'] ? 0 - $depth : $depth);
        }
    // No match found
        return false;
    }
