Clear Chatroom text function

[pSouper]

Hi Oliver [et al],

Apologies in advance Oliver if this is an unwelcome post - I will delete it if you ask.
----------------------
If like me you would like to clear the chatroom text without running to phpmyadmin then I have a very dirty cheap way to do it.

create a new .php... includes/inc_Lib/admin.EmptyChat.php

Code: Select all

?>

<?php
$sql = "DELETE FROM ".DB_PREPEND."phpwcms_chat;";
if($result = mysql_query($sql, $db) or die("error Deleting Chat repository"))
echo "Chat Repository has now been cleared";
?>

then add this line to includes/inc_Lang/Backend/en/lang.inc.php at the end of the //phpwcms.php section...

Code: Select all

$BL['be_subnav_admin_EmptyChat']          = 'Clear Chat Text';

then in phpwcms.php add this new line of code directly after this existing line...
$subnav .= '<tr><td colspan="2"><img src="img/leer.gif" height="5" width="1"></td></tr>'."\n";

Code: Select all

$subnav .= '<tr><td colspan="2"><img src="img/leer.gif" height="5" width="1"></td></tr>'."\n";
$subnav .= subnavtext($BL['be_subnav_admin_EmptyChat'], "phpwcms.php?do=admin&p=12", $p, "12", 0); 

then add this new line of code directly after this existing line...
case 11: //Templates
include_once "./include/inc_tmpl/admin.templates.tmpl.php";
break;

Code: Select all

case 12:	//EmptyChat
include_once "./include/inc_lib/admin.EmptyChat.php";
break;

This works for me but you may want to back up your database first
I can't support this function, accept no liability and will offer no refunds.
a new version with a warning/notification box and nicer varification will follow some day
