Make them an array by adding [] at the end of the name. Also you are
missing a quote at the start of the value= (double quotes makes it
easier to print in my opinion)
It should be like this:
while (!$recordSet->EOF) {
print($recordSet->fields[0] . '<input name="interesses[]"
type="checkbox" id="interesses" value="' . $recordSet->fields[0].'">'
);
Then any checkboxes checked will be in an array called interesses
$interesses = (isset($_POST['interesses']))? $_POST['interesses'] :
array();
if(count($interesses) > 0){
//checkboxes have been ticked
}else{
//none ticked
}

Tom
