From Oscar: Extracting parameters from Request URI

Thursday, June 10. 2004

Problem: On a Syntax site, You have a uri like http://www.mysite.com/content/news/detail/5678/ and you need to extract the number to use as your record id:

you could do it the wrong way in bare php:

        $uri = explode('/',$_SERVER['REQUEST_URI']);
        $id = $uri[4];
        if(preg_match("/\?/",$id)) 
        {
                $elements = explode('?',$id);
                $id = $elements[0];
        }

or you could do it using the more readable/maintainable Syntax way:

        if ($Request->getVar('id')) {
	        $id = $Request->getVar('id');
        }
        else 
        {
               // look for it in the Request trailpoint (assumes it's 3rd element
               // in path since content/ doesn't count and index starts at o );
    
               $id = $Request->getPathElement( 2 );
    
               if ( !is_numeric( $id ) || empty( $id) )
               {
                       trigger_error( 'Non-numeric or missing record id.', E_USER_ERROR);
               }
        }
