How to make a text replacement in PHP? - php

Question

so im adding commands to a very popular vbulletin plugin, and there's this one i cant seem to get to work properly no matter what i try. The code i have so far is
$cybcb_checkban = strpos($vbulletin->GPC['ccb_newmessage'], '/ban');
if($cybcb_checkban !== false AND $cybcb_candelall)
{
$banuserurl = $vbulletin->options['bburl'].'/misc.php?'.$vbulletin->session->vars['sessionurl'].'do=ccb_banuser&u=2';exec_header_redirect($banuserurl);
}
what i need it to do is the part that says
do=ccb_banuser&u=2
is replace the 2 with the text entered in my chat.
vbulletin kinda has its own language but the base concept of it is PHP
but for reference, this is a default command already in the plugin
$cybcb_checkme = strpos($vbulletin->GPC['ccb_newmessage'], '/me ');
if ($cybcb_checkme !== false)
{
$vbulletin->GPC['ccb_newmessage'] = str_replace('/me ', $vbulletin->userinfo['username'].' ', $vbulletin->GPC['ccb_newmessage']);
$vbulletin->GPC['ccb_newmessage'] = '[color='.$vbulletin->options['cybchatbox_mecolor'].']* '.$vbulletin->GPC['ccb_newmessage'].'[/color]';
}
I've been playing around with this for a few days now, and the only result I've got semi working is the first code at the top, the problem with that as you may have guess by entering
/ban (USER ID HERE)
the only user that will get banned is user 2 (obviously)
so i just need something that will give the code the ability to be /ban (userID)
i know its got to be something like
$banuserurl = $vbulletin->options['bburl'].'/misc.php?'.$vbulletin->session->vars['sessionurl'].'do=ccb_banuser&u=.$vbulletin->GPC['ccb_newmessage']';exec_header_redirect($banuserurl);
but that doesnt seem to work =/ anyone have the answer? or can point me in the right direction, I'd be very grateful =) thanks.

Answer 1

$vbulletin->GPC['ccb_newmessage'] will contain the whole message, so if you send
/ban 123455
$vbulletin->GPC['ccb_newmessage'] will have /ban 123455
what you can then do is remove '/ban ' and you'll be left with the User ID
so something like
$cybcb_checkban = strpos($vbulletin->GPC['ccb_newmessage'], '/ban');
if($cybcb_checkban !== false AND $cybcb_candelall)
{
$vbulletin->GPC['ccb_newmessage'] = str_replace('/ban ', '', $vbulletin->GPC['ccb_newmessage']);
$banuserurl = $vbulletin->options['bburl'].'/misc.php?'.$vbulletin->session->vars['sessionurl'].'do=ccb_banuser&u=' . $vbulletin->GPC['ccb_newmessage'];
exec_header_redirect($banuserurl);
}
or
$cybcb_checkban = strpos($vbulletin->GPC['ccb_newmessage'], '/ban');
if($cybcb_checkban !== false AND $cybcb_candelall)
{
$banuserurl = $vbulletin->options['bburl'].'/misc.php?'.$vbulletin->session->vars['sessionurl'].'do=ccb_banuser&u=' . substr($vbulletin->GPC['ccb_newmessage'], 4);
exec_header_redirect($banuserurl);
}
should work
note: that 4 should probably be replaced with something like substr($vbulletin->GPC['ccb_newmessage'], strpos($vbulletin->GPC['ccb_newmessage'], '/ban') + strlen('/ban'));
