This bit of code is getting run BEFORE the submit button has been
pressed.
In that case, $_POST itself is not defined, much less $_POST['heading']
You really shouldn't be stuffing values into $_POST. Think of it as a
read-only variable that the browser sends TO you.
Here are some options:
OPTION 1:
<?php
$heading_insert = '';
if (isset($_POST['heading'])){
$heading_insert = stripslashes($_POST['heading']);
}
?>
OPTION 2:
<?php
$heading_insert = isset($_POST['heading']) ?
stripslashes($_POST['heading']) : '';
?>
Some people think the ternary operator is "confusing" or "obscure" or
whatever. Others think it's a perfectly natural operator. YMMV
