Dummy question about knowing marked checkboes

Hi, First of all, my apologies to all list members for this dummy question. I've made my home work before posting here, but the truth is that i didn't found an answer for such a simple question. Only examples of more sophisticated related things. I have this piece of code that produces various checkboxes inside a form: ------------------------------------------------------------------- // select interesses names and values to build the chekboxes $recordSet = &$conn->Execute('SELECT interesses FROM interesses ORDER BY interesses ASC'); // build the checkboxe's list if (!$recordSet) print $conn->ErrorMsg(); else { while (!$recordSet->EOF) { print($recordSet->fields[0] . '<input name=\'interesses\' type=\'checkbox\' id=\'interesses\' value=' . $recordSet->fields[0] . '\'>'); echo"<br />"; $recordSet->MoveNext(); } $recordSet->Close(); $conn->Close(); } --------------------------------------------------------------------- Here's the correspondent HTML output: --------------------------------------------------------------------- Alojamento<input name='interesses' type='checkbox' id='interesses' value=Alojamento'><br /> Artesanato<input name='interesses' type='checkbox' id='interesses' value=Artesanato'><br /> Eventos<input name='interesses' type='checkbox' id='interesses' value=Eventos'> (etc.) --------------------------------------------------------------------- My dummy question, for which i apologise once more is: after submitting the form, how can i know which chekboxes were checked ? Thanking you in advance. Warm Regards, Mário Gamito
