[MYQLI ERROR]

Hello everyone

 

about 4 days am experiencing this problem if you can help me out this is the code; it's not updating at all it's just redirecting me to the page

 

$db = new mysqli($dbHost, $dbUser, $dbPass, $dbName) or die (mysql_error());

function editcat($cid,$name,$desc,$ok=false) {
global $db;

$cid = intval($cid);

if (!$ok) {
	$result = $db->query("SELECT * FROM category WHERE cid='$cid'");
	$row = $result->fetch_object();
        $cid = $row->cid;
	$name = $row->name;
	$desc = $row->desc;

	echo "<table width='100%' align='center' cellspacing='0' cellpadding='1'>\n";
	echo "<form name='form_editcat' method='post' action='index.php?page=articles&op=editCategory&cid=$cid&ok=true'>";

		echo "<tr><td><b>Name</b><td><input type='text' name='name' size='40' maxlength='255' value=\"$name\">\n";
		echo "<tr><td><b>Description</b><td><input type='text' name='desc' size='40' maxlength='255' value=\"$desc\">\n";
		echo "<tr><td colspan='2'><input type='submit' name='Submit' value='Modify'>\n";

	echo "</form>\n";
	echo "</table>\n";
} else {	
	$save = true;

       if ($name=="") { $save = false; $msg = "Name field is empty!";}
       if ($desc=="") { $save = false; $msg = "Description field is empty!";}

	if ($save) {
		$db->query("UPDATE category SET name='$name',desc='$desc' WHERE cid='$cid'");
		echo "<meta http-equiv='refresh' content='0;URL=index.php?page=articles'>";
	} else {
		echo "<div align='center' id='errorText'><b>$msg</b></div>";
	}
}
}
