Simple unregistered chat system on PHP

PHP is well known server side language for web programming. Solutions of web needs, php is the language you can find resources on the web easily. Here in this contribution i will explain how to make "unregistered simple chat system" for your website.

First we have to create new database. I had named to my database as "simplechat".

Then we have to create new table. I had named it as "chat_msg".

ID is int autoincrement,
username is varchar,
msg is text
date is datetime 0

Before we start, you have to know that people will not register to this system. They will put their names, text whatever they want and we will add the date when they sent it.

Lets start code our html first of all.

<form method="post">
<input type="text" name="username" placeholder="Username">
<input type="text" name="message" placeholder="Write something...">
<input type="submit" name="send" value="Say it">
</form>

Basicly we just create some inputs needed from user.

Now lets start to code it in php;

In the picture as you can see, we create a connection to the database we already created.

Get data from inputs;

$username = $_POST['username'];
$message = $_POST['message'];

And then set the timezone, date type;

date_default_timezone_set("Europe/Berlin");
$datedate = date("Y/m/d/H/i/s");
``$error = false;` ( For not to get only msg or only username, always protect yourself by the error ).

Now we are done to get datas from user and insert into our database. Next step should be the show what is the users names and messages also when?

Created a loop to show what has ben sent already, order it by id and limited to 10 messages in a row. We had been set datetime to show which day month year hour etc.

Now lets add one more time;

If i couldnt fill the forms, there should be warn and no insert to the database,

I hope you enjoy and enlight to think how can you solve your issues quickly.

Have fun...
