Re: Variable variable

Sorry - thought you only had one! - it's late. To Name the checkboxes you need: <?php while (get records from db) { $id = id from record; ?> <input type="checkbox" name ="<?php print $id; ?>"> <?php } ?> You would have to do a $HTTP_GET_VARS on the next page to find out which ones exist. Then your select statement would be: $query = "select * from table where id IN ('comma delimited list of values')"; Messy but do-able! Probably a better way - There usually is!
