Sure

Code: Select all

<form method="post">
<input name="u" value="user">
<input name="m" value="message">
<input type="submit">
</form>
<?php
if (array_key_exists("u", $_POST) && array_key_exists("m", $_POST))
{
 $chat = $_POST["u"] . ": " . $_POST["m"] . "\r\n";
 echo $chat;

 $file = date("Y-n-j") . ".txt";

 $fw = fopen($file , "a") or die("<div>Could not open, create or write to $file.</div>");
 fwrite($fw, $chat) or die("<div>Could not write to $file.</div>");
 fclose($fw);
}
?>

You could take out the html and just have it as a php script, then your program can directly post/receive echoed messages, and since the server handles the chatlog your clients don't need even direct access to it.

hey how would i make read in vb?

First get rid of the input element, thats just if someone visits the page in a browser. Next you'll have to put that script on a PHP-enabled server.

Once its in place you can use this to post messages from the client:

Code: Select all

        Dim wc As WebClient = New WebClient()
        Dim u As Uri = New Uri("http://localhost/chat.php")
        Dim values As System.Collections.Specialized.NameValueCollection = New System.Collections.Specialized.NameValueCollection()
        values.Add("u", "user")
        values.Add("m", "message")

        Dim data As Byte()
        Try
            data = wc.UploadValues(u, values)
        Catch ex As Exception
            MsgBox("Error posting chat: " & ex.Message)
            Return
        End Try

        Dim chat As String = System.Text.Encoding.ASCII.GetString(data)
        txtChat.Text += chat & vbCrLf

Then occasionally you can have the client refresh the chat log from the file that is stored on the server.

Silluser: message
<br><table border='1' cellpadding='2' bgcolor='#FFFFDF' bordercolor='#E8B900' align='center'><tr><td><font face='Arial' size='1' color='#000000'><b>PHP Error Message</b></font></td></tr></table><br />
<b>Warning</b>:  fopen(2010-5-24z61chat.txt) [<a href='function.fopen'>function.fopen</a>]: failed to open stream: Permission denied in <b>/home/a9136110/public_html/chat.php</b> on line <b>9</b><br />

That code looks hard I dont know how you would do this i would like to learn :P

[mandai]

Your web host is putting extra code in the bottom of the php script, plus it is blocking you from writing to/reading from the txt file.
Check your security settings to make sure scripts can read/write in the current directory.

[Lewis]

On the 000webhost file manager you have to CHMOD It 777 basicly ' read/write in the current directory'
