The idea I had was for a "multi-questionnaire" system, where surveys are created from a database query, scored by a common marking script, and the results stored back to the database. Obviously, the marking script can't know what inputs to expect... My first idea was to create a parseable "variable-names-to-look-for" variable, but that seemed unwieldy. Then I recalled someone complaining about not being able to retrieve multiple input fields with the same name - they only get the last ie most recent field set. ;-) and there's the answer. If you have a hidden input with the same name and a default value _before_ your checkbox input, then your checkbox will over-write it if it's checked; otherwise you receive the default value! ie <input type="hidden" name="myvariable" value="No"> <input type="checkbox" name="myvariable" value="Yes"> if the checkbox is checked, $myvariable = "Yes", otherwise $myvariable = "No" - exactly what you were looking for. Better yet, because $myvariable only occurs once among the POSTed variables, you can simply iterate through them, ie foreach($HTTP_POST_VARS as $name => $val) $outstr .= "<br>$name: $val"; See the attached file, 'test.php', for a simply demo. begin 666 test.php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
