Well, for instance. I don't like forms that submit to the same page where
it is located. Separating them helps to maintain the code (usually). I don't
like html inside <?php so 99% of the times I escape with ?>.
Btw, you should start with <?php and not <?.
Your input is missing the /, newer versions of HTML (or XHTML) recommend
to finish tags that explicitily don't have a finishing term, with /. So
it's:
<input type="text" name="data" />
And if $submitdata is expected to come from a form, check it:
if ($_SERVER['HTTP_REFERER'] == 'somepage.php') {
if (isset($_POST['submitdata'])) {
dosomething;
}
}
I also don't like to exit(); programs, but I don't know your whole
situation, so your mileage may vary.... And sometimes use a } else { on
expected values with some nasty error messages (just in case someone is
trying to 'crack' your app).
