A Free PHP Live Chat Box HTML Code Section.This time we have a session set with the user name value, so the if statement will activate the second part of the script this time. Then we redirect the user back to index.php page using the header() function. Do some basic filtering of the user name and color provided via the form, and assign the values to session variables. Īgain, the first thing we do is to start our session with session_start(). We are not fully validating the submitted values here for simplification reasons, but for security sake it is wise to assure the submitted values are valid. Now let us create a simplified version of the login.php script. Then clicks on submit button that will submit the form to the login.php script. The user enters a user name and chooses a color from the dropdown select element. Very simple, one table in a form with two fields: nickname and color. So if $_SESSION variable is empty, we show a form. Now it is empty but later we will add code there. If he did go through the login form, we show what is after the "else" keyword. After that a simple test, if the user has not registered his user name in the session we will show the form. We need to start the session before we print anything on the screen. Let us create the first section with a script file named index.php: įirst thing we do in this script is to call start_session(). After the browser returns to the first page again but now showing the chat interface instead of the login form. Then he submits the form which will be handled by a script to set the session. The form on which the user provides his user name and color. The Session Login Section for Creating a Chat Room.It is the same URL but the user sees one section a time. When he submits the login form, the browser will be redirected to the chat screen. When the user comes for the first time, he will not have a user name in the session, and he will get a form to write down his user name and choose a color. Here we create two sections in the frontend file: one for login and the other for chat. Later we need to store this user name, so we do not need to ask him to enter his name every time he sends a message. When a user comes to the chat room page he needs to have a user name, so first we need to give him a way to choose one. It is not complete solution but it is enough for the purposes of this tutorial. The Frontend JavaScript, CSS and HTML Chat Box ScriptĮvery good chat system has some kind of user management system.The table uses the MyISAM engine and character set is UTF-8 as it supports most languages. This is how we know when the chat line have been submitted. The chattime field is a timestamp field for which MySQL will set as default value to the current time. It contains an ID field which is the primary key and so it is auto-incremented, a nickname, color and chattext fields, strings with different lengths. I have named the table "chat" for obvious reasons. ) ENGINE = MyISAM CHARACTER SET utf8 COLLATE utf8_unicode_ci `chattime` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP , My proposal is to have a color field so we can show each user chat lines in a different way. It is also useful to have something to distinguish what each user said. :-)įor a simple chat room system we will need just one table, it stores the nickname of the user, what he said and the time when he said it. So next time when you chat with some one, keep in mind it is saved somewhere there. Some solutions use sessions, others use text files, but the most robust solutions use a database. The PHP Chat Script with Database StructureĮvery chat room needs to keep the content of the chat lines stored somewhere.Here is a screenshot of a PHP chat system page that you can create following the steps described in this tutorial: Here you may find the complete source code of a PHP package for implementing this chat service.
