checking for data before doing sql insert

I have a html form (generated by PHP) that users can fill out and submit
into a database. Everything works fine. However, I'd like to check to make
sure that each field in the form actually contains data (no null/void
fields) before doing the insert into the database. Any tips on how to do
this?

Thanks,
Bart

one idea is to do something like this...

function checkForm() {
if (!empty($_REQUEST['formitem1']) && !empty($_REQUEST['formitem2'] &&
!empty($_REQUEST['formitem3'] etc...) {
return true;
} else {
return false;
}
}

if (checkForm()) {
// insert stuff into database here because checkForm() returns true
} else {
print "Please fill out all fields in the form";
}
