For the first line of the code you provided; [code]$viewid = intval($_GET["id"]);[/code] will be better for security ...

Hi all, I've found this site during searching google for my security questions. One of the biggest problem in web programming is securiy. There are lots of "to-do's" but sometimes we can miss the simple points. I am working on a link manager project which will be usable by public. I decided to implement "limit the allowed characters" method for protection. For example; I am using [code]$string = eregi_replace('[^a-zA-Z0-9]','',$string); return $string;[/code]for parsing and cleaning user inputs. But the problem is parsing and inserting the user provided url's to db ... How should i handle user urls ? I am redirecting users with this frame setup; [code]<frame name="main" src="<?=$url;?>" scrolling="auto">[/code] Any idea ? Thanks
