Custom MySQL Function W/ Error Handling

[ShoeLace1291]

I was tired of having to type out the same code over and over to report mysql errors  while indicating where they occur.  So I decided to write my own function to handle the errors.  However, it doesn't seem to be working properly. 

 

 

function DbQuery($query, $file, $line){

    

    if($execute = mysql_query($query)){

        

        return $execute;

    

    } else {

        

        return '

                        <p>You have an error in a mysql query.</p>

                        

                        <p>File: '.$file.'</p>

                        <p>Line: '.$line.'</p>

                        

                        <p>Query: '.$query.'</p>

                        ';

                        

    }

}

 

I tested it out with this bit of code.  When everything is ok with the query itself, the function works perfectly.  If there is a syntax error, I get a php error saying that mysql_num_rows expects parameter 1 to be resource... which I know why, but I can't figure out how to skip that part, and go right to my custom error.

 

 

$query = DbQuery("

            SELECT

                member_id,                email_address,

                recieve_member_emails,      recieve_admin_emails

            FROM ".DB_PREFIX."members

            WHERE member_id = ".$mbr['id']."

            LIM 1", __FILE__, __LINE__);

            

        if(mysql_num_rows($query) > 0){

            

            $member = mysql_fetch_assoc($query);

            var_dump($member);

            

        }

 

Thank you for your time.
