I'll admit it upfront: I am a total noob to this, so please bare with me. I'm trying to create a simple PHP program with an HTML form to submit an input into PHP which then echos back the user's input but I keep getting an "Object not found!" error when I push the submission button on the page. If you could please tell me what I'm doing wrong, I would really appreciate it. My code is: <form action="index.php" method="post"> <input type="text" name="user_input" size="20"> <input type="submit" name="press" value="Press da button!"> </form> <?php if (isset($_POST['user_input'])) { $post= $_POST['user_input']; echo "You posted $post ."; } ?> Again, thanks a ton.
