Re: checking if checkbox is checked

To check if a type checkbox variable has been set use isset() i.e. if ( isset($interest) or isset($interest2) or isset($interest3) or isset($interest4) or isset($interest1) ) { // Everthing is ok } else { $error = ..... ) This should do exactly what you want, and although it may not use the least characters it should be the quickest to write/debug/maintain and run.
