Hi Shaun,
Your expression is evaluating, if you like does the $_POST superglobal
exist and it does
but might be empty, this would be the same for $_GET and other superglobals.
If you did the following:
if (isset($_POST) && !empty($_POST)) {
echo '(isset($_POST))';
}
This would only appear if there was in fact a $_POST variable 'set'.
If you want to test to see if a form has been submitted, I would suggest
that you
use the name from the submit button.
e.g - <input type="submit" value="Send Form Data" name="sendform">
if(isset($_POST['sendform'])){
echo "Form has been submitted!";
}
So basically this checks if the form button "sendform" is set.
HTH,
Craig
