There is a form on the page with a post method and some submit
buttons, however, none of them are triggered here. The script is
called using an <a>tag with this kind of thing:
<a href = "<? echo 'http://' . $_SERVER['PHP_SELF'] . '?pid=' .
$row[id]; ?>" >Delete</a>
It just leaves the page and starts again at the top of the script. It
works fine. What caused me to catch it is that I was using:
if (!isset($_POST))
to set a switch variable in the case that the data had not been sent
via a post submit. It wasn't working so I checked and found the
$_POST variable was sure enough set, but empty.
What would be setting the $_POST variable if the form wasn't
triggered.
