Trying Update Record with PDO

Question

I updated the question code I am still having issues no errors but does not update the record. also need to figure how to write in record # updated successfully. I am stuck on t

Answer 1

This code is a disaster:

$affected_rows = $db->exec("UPDATE requests SET") . 
                                               ^^---terminating your query here
                "lanId =  '" . $lanId . "', ".

So you run a malformed query (UPDATE requests SET), which will either throw an exception of return boolean FALSE. You then concatenate a whole bunch of text (which would've been part of your query) onto that FALSE.

And even if this code was properly structured, you'd be WIDE OPEN to sql injection attacks.
