Thank you Aziz, Interesting link, thank you for that. I have not worked with prepared statements on my own, just in WordPress. So the @ symbol is a preferred method even outside the SQL world because? What specifically is the @ symbol doing? From what I read, and from what you just mentioned, it's the PHP->SQL driver that check this @ symbol and treats the data as literal text? Meaning it will not execute the text that comes after the @ symbol as code. Yes? Best, Karl DeSaulniers Design Drumm http://designdrumm.com
