Hi Zoilus,
The one and foremost way to debug form-postings (in my humble opinion of
course) is dumping the posting in PHP.
for example: You post a form with method="post" to search.php
then in search.php start with this:
<?php
// dump the post
echo "<pre>";
print_r($_POST);
echo "</pre>";
exit;
?>
I must have typed the sequence of lines a zillion times by now. ;-)
You can do the same with $_GET (for forms that use method="get").
or for cookies: $_COOKIE
or actually for any array you might want to inspect.
Do not forget the <pre>..</pre> because print_r() is nicely formatted only
if you use pre.
Hope that helps.
