javascript onexit's can test for non-null field contents;
without javascript, at the top of the POST or GET, you can add
this kind of test before processing:
<?php
//... stuff
$var = $_POST[var];
// ... detaint against hostile content omitted
if ("$var" == "") {
print "Error: var cannot be empty <br>";
$retry = "y";
}
// ... stuff omitted
//
// and then test for an error before dispatching to a
// processor
if ("$retry" == "") {
header("Location: http://www.domain.com/handle_post.php");
} else {
print "Some errors were noted, as above -- let's retry <br>";
}
