There was a typo in change_query
Here is the corrected version
function change_query($action, $var = NULL, $uri = NULL) {
if (($action == "+" && !is_array($var)) || ($action == "-" &&
$var == "") || $var == NULL) {
return FALSE;
}
if (is_null($uri)) { //Piece together uri string
$beginning = $_SERVER['PHP_SELF'];
$ending = (isset ($_SERVER['QUERY_STRING'])) ? $_SERVER['QUERY_STRING'] :
'';
} else {
$qstart = strpos($uri, '?');
if ($qstart === false) {
$beginning = $uri; //$ending is '' anyway
$ending = "";
} else {
$beginning = substr($uri, 0, $qstart);
$ending = substr($uri, $qstart);
}
}
$vals = array ();
$ending = str_replace('?', '', $ending);
parse_str($ending, $vals);
switch ($action) {
case '+' :
$vals[$var[0]] = $var[1];
break;
case '-' :
if (isset ($vals[$var])) {
unset ($vals[$var]);
}
break;
default :
break;
}
$params = array();
foreach ($vals as $k => $value) {
$params[] = $k."=".urlencode($value);
}
$result = $beginning . (count($params) ? '?' . implode("&", $params) :
'');
return $result;
}
