This is an update to original Chat Room we published here on CSS-Tricks. We are going to employ PHP to talk to the server, j Query to keep the chat rolling, and the chats themselves will be stored in files just like the first version.

What is changed is the addition of some new features: While the first version of this used no database at all, we are going to employ a little My SQL for this version.

There is a file in the download called for use in building the initial database.

Using some j Query, it makes an AJAX request to see if that username is currently in use in the database.

If it is in use, you get a warning: Otherwise, it says it's cool: If it is cool, and you click to join the chats, that username will be put into the database and thus further checks for it's name will tell others that name is unavailable. The names of the chatrooms are kept in the database.

To add a new chatroom, just add a new row to the database with the name of the chatroom and the filename of the text file you intend to store the chat: Then it's just a matter of making sure the text file is on the server in the right place with proper server-writeable file permissions (see the download for properly location).

I'm sure you've noticed by now we haven't been looking at any actual code. All the code is available in the download (see below).

It is not so incredibly much that it's overwhelming, but I think it's too much for a standard written tutorial/overview.

Instead, let's overview what it's responsible for: Username checking: On the homepage of the chat, when you choose your username, j Query is there watching that text input.

When you type a character (on keyup) it asks a certain PHP file (via AJAX) if that username is in use.

The PHP file responds with a yes or no, and a message is appended to the screen accordingly. Download Files UPDATE: It turns out there was a SECURITY PROBLEM with one particular aspect of it, which can get grant access to any file on the server.

Message box: When a user types into the textarea for sending a message, the j Query watches that box and ensures the text is under a certain number of characters (set via maxlength attribute on the textarea) Sending message: When the return/enter key is pressed in the chat box the value of it is sent for processing. Updating the chat: Every few seconds, j Query asks a PHP file to poll the text file to see if there are any new lines, if there are, they are displayed. A reader was able to show me how they could publicly access my Word Press file, which is of course super sensitive.

The vulnerability is in the file, which accepts a "state" and "file" parameter.

Accessed directly, and with a relative file path, you can get access to protected files that way.
