In Part 2 of this tutorial, we taught you how to add user authentication to the forum. In this part, you will learn how to build the page that enables users to post a new message to a topic.

The page will be accessed through a link that appears on the message list page. The link will pass the id_top URL parameter, which contains the identifier of the topic to which the message belongs. In this part, you will do the following:

• Add the link for posting messages in the view_message.php page.
• Restrict access to the page for posting messages so that only logged-in users are able to access it.
• Create the form for posting messages to the forum, which also inserts the information into the message_msg table.
