There are many chat programs out there which use mysql etc if you just want a chat program, however if you are doing it for a learning exercise, remember that PHP is a server-side language and you will probably have to use javascript or flash to handle the client browser part. If you need specific help on a specific problem, then you need to post a specific snippit of code (not the whole thing but the part ~10-15 lines which is not working)

Yes ocpaul20, I am doing it for learning purpose.........and here are the lines where think the problem may be....

<form method="post" action="">
<table width="200" border="1">
  
  <tr>
    <td>Message:</td>
    <td>
    <input type="text" name="des" placeholder="Type Something.."/></td>
  </tr>
  
  <tr>
    <td></td>
    <td><input type="submit" name="sub" value="Send"/></td>
  </tr>
</table>
</form>


$des=$_POST['des'];

if(isset($_POST['sub']))
{
$cht=new forms();
$arr=$cht->sndAcptMsg($des);
}

 

Where 'sndAcptMsg' is a function containing all the queries...please have a look if i am doing something wrong.....any help greatly appreciated....

Well, I normally put the test of POST _{at the top and then the HTML at the bottom. That way I can just drop through if the form has not been submitted.}

_{To begin with, I would probably hard code some messages rather than getting them from the database and then when the logic was correct, I would add parts of the program together. That way I would know the thing was working as I was building it. Anything not working would be the part I slotted in last.}

 

_{There are PHP tutorials which build up a chat client/server application. They explain what each step does. Look up sockets for example. You can always add the database part after you have got the client/server sockets talking to each other.}

_{Have fun.}
