simple simple chat (help)

nicknax

Hey guys,

Yep, me again.

I wondered whether there was an easy way to display the latest chat down bottom instead of up top on the simple simple chat script.

<?php

/****************************/

// Warning : This chat exposes chatters IP addresses

// Config : [ You can change these options ]
$refresh = 6 ; // Page refresh time in seconds
$max = 20 ; // Max. saved messages
$remain = 400 ; // Messages remaining time in seconds
$file = "msg.txt" ; // Message storing file
/
You may need to make an empty file (use notepad) and name it "msg.txt"
($file), and send it to your server. Then CHMOD this file to 777 - e.g :

// End of config //

$user = $HTTP_SERVER_VARS['REMOTE_ADDR'] ;
$f = file($file) ;
$users = array($user) ;
header ("Content-Type: text/html; charset=utf-8") ;
$fp = fopen($file, "w") ;
if (!$fp) { die ('Can not write to file .') ; }
for ($i=0; isset($f[$i])||$i==0; $i++)
{
$e=explode('||', $f[$i]) ;
if ($e[2]=="\r\n" && !in_array($e[0], $users) && ( time() - $e[1] < $refresh*2 ) ) $users[]=$e[0] ;
if ($i==0) { fputs($fp, $user."||".time()."||\r\n") ;
if ( isset($HTTP_POST_VARS['msg']) ) fputs ($fp, $user."||".time()."||".str_replace("||", "", str_replace("\n", "", htmlspecialchars(stripslashes($HTTP_POST_VARS['msg']))))."\r\n") ; }
if ( ($e[0]!=$user && $e[2]=="\r\n") || ( $i<$max && ($e[1]+$remain)>time() && $e[2]!="\r\n") ) fputs($fp, $f[$i]) ;
}
fclose($fp) ;

if (isset($HTTP_GET_VARS['f1']))
{
$f2 = file($file) ;
echo("<html><head><title></title><meta http-equiv='Content-Type' content='text/html; charset=utf-8'></head>") ;
echo("<body text=#0000cc><meta http-equiv='refresh' content='{$refresh}; url={$HTTP_SERVER_VARS['REQUEST_URI']}'>") ;

echo "</font><hr>" ;
for($i=0; isset($f2[$i]) && $i<$max; $i++) {
$e=explode("||", $f2[$i]) ;
if ($e[2]!="\r\n") echo "<font color=green>{$e[0]}</font> <font color=red>:</font> {$e[2]}<br>\r\n" ;
}
die("</body></html>") ;
}

else
{
die("
<html><head><title>Chat</title><meta http-equiv='Content-Type' content='text/html; charset=utf-8'>

</td></tr></table>

") ;
}
?>

Hope someone can help 🙁

I want the newest chat down bottom, and older chat to go up to top, instead of the other way round.

You'd probably get better help if you used [php][/php] tags instead of using quotes when displaying PHP its extremely hard to focus on it.

this doesn't appear to make any difference.

Does anybody know how to make this script so that latest chat is down bottom?

bretticus

I never changed any of the code. In response to...

You'd probably get better help if you used
tags instead of using quotes when displaying PHP its extremely hard to focus on it.

I put it in quotes. I did look through the code, but it's not the most consise or clear code. Where did you get it? What chat client is it for? Can you provide a sample msg.txt file. Will you at least TRY so you can explain what you tried. Often that is the best way to be answered in this forum. We like to see some effort instead of just giving it to you on a silver platter.

Good Luck!

Agreed that is some terrible code to read a even when using the [php][/php] a suggestion into using coding practices

Example 1:

if ($e[2]=="\r\n" && !in_array($e[0], $users) && ( time() - $e[1] < $refresh*2 ) ) $users[]=$e[0] ;

Example 2:

if (!$fp) { die ('Can not write to file .') ; }

Example 3:

if (isset($HTTP_GET_VARS['f1']))
{ 
//code here
}

Hmm 3 ways to do it and all three used in the source. Hmm very hard to understand.

header ("Content-Type: text/html; charset=utf-8") ;

Any reason for the header 😕 Im pretty sure text/html is the default sent by PHP and Apache I dont think its required to be sent again.

Roger_Ramjet

nicknax, I hope you see my fix: look for the ************

The chat is in an iframe and I moved it below the table holding the input form.

nicknax

Oops, i think you're misreading my query.

When the chat writes to the text file, i would like the latest chat to be written down the bottom of the text file instead of up the top, consequently, the latest chat typed will be shown towards bottom of page, instead of top!

Hope someone can help!
