Answer 1

I think your code should be, anyway i dont know php code is in separate file and html/tpl code in separate file.

if ($_GET['action'] == 'edit' && $_GET['id']) {
       $sel_cat =$cate_id ;
      } else {
      $sel_cat = "";
      }
      construct_cat_ops($sel_cat);
     $tmpl->setvar('cat_ops', $cat_ops);

<select name="category" class="field" style="width:160px" >
       <option value="0">Select</option>
        {var name='cat_ops'}
       </select>

      if ($_POST['update'] && $_POST['hid_id']) {
      if($brand==$categoryname){
         $msg = "Parent category cannot be same";
         $tmpl->setvar('msg_err', $msg);
       }else{
      $db->query("Update `blog_category` set`name`='$brand',`parent`='$category' where id='" . $_POST['hid_id'] . "'");
      $msg = "Blog category Updated Successfully";
      $tmpl->setvar('msg_ok', $msg);
      $tmpl->setvar('name', $brand);
  }
}
