Hi.... it is my first hack - phpProbe

here is it... it was tested under vbb2x RC2 and phpMyChat 0.14.4

News:
Updated on 19.07.01
- FAQ has been add

Updated on 18.07.01
The hack is compatible with version 0.14.5 of phpMyChat
- there is some javaScript code there, so the hack will not work with browsers without JS support (phpMyChat will not work with these browsers too

)
- the Exit link in chat works ok now

Hack:
Step 1:
open /lib/index.lib.php3 in yours phpMyChat Derictory
find:

FAQ:
Q: I`m getting "no" every time.
A: You need to upgrade a cookie option in your VB control panel. Write under: Options->Change Options->[HTTP Headers and output]->Cookie Domain your domainname ONLY (blabla.com).

Q: I`m getting "you need to register" error.
A: Enable chat using for not registered users in your phpMyChat config (/config/config.lib.php3).

Q: I`m getting "wrong password" error.
A: Make shure you have deleted all user accounts in your chat and have only administrative one. If you are logging is as administrator note that you have to enter your password EVERY time you are logging in.

try to reinstal index.lib.php3 form archive and reenter the hack

mADmAX` · #**133** 08-12-2001, 08:12 PM

I figured it out, it seems that after I updated it, the tables that your hack creates was deleted. Works now... Thanks!

Stasik · #**134** 08-12-2001, 08:35 PM

np

bitbender · #**135** 08-12-2001, 09:33 PM

I've done the steps specified. I cannot seem to figure out what goes in the chat.php element (or is it a template?)

It seems that I cannot get anything other than a blank page when I select my chat button from the VB index.php....

the base install of chat was functional, and my problems came when I tried to integrate it, which I KNOW is a user error!!

I followed a thread http://vbulletin.com/forum/showthrea...ight=phpmychat which talks about a chat.php, but i'll be dogone'ed if I can find an example!

HELP!!! I see too many people who say "They got it", so I know I've done something stupid, or I'm just being dense!!!

Alert ---> Old Mainframer doesn't get this one!!!

Stasik · #**136** 08-12-2001, 09:36 PM

no... the thread is talking about the file index.lib.php3 in the /chat/lib/ derictory...

bitbender · #**137** 08-12-2001, 10:21 PM

ok, so is that where the link on the chat button points to ??

Stasik · #**138** 08-13-2001, 07:24 AM

no, the link poins to index.php3, but this file uses /lib/index.lib.php3

bitbender · #**139** 08-13-2001, 10:53 AM

Yes. The reason I asked was that I had tried that b4. When I point it(chat button) at /chat/index.php, I'm redirected back to the forum home page, as if the user had joined, and then left chat. I then tried index.lb.php3, but get a blank screen.

This is because of the hack that was added to index.php3 via the thread I mentioned before. It dicussed your hack and two other parts, which affected index.php in the VB forum directory, and
index.php3, and index.lib.php3, and exit.php3 for myphpchat.

thank you for your time. I will continue to analyze my setup. I am still thinking that I have the hack in VB INDEX.PHP misplaced. I tried to represent the variable ($numchatusers) on the home page via the forum_loggedinusers template, and got a blank field display for my efforts. That would indicate to me the code isn't being executed where it needs to.

I placed the hack at the very end of index.php in the VB forum directory. One of the other reasons I know I've something out or ordung is that the chat doesn't open in a seperate window, as the hack documentation indicated it should.

Help This old fool, please

bitbender · #**140** 08-13-2001, 10:57 AM

Forgot the link to the thread in question:

http://www.vbulletin.com/forum/showt...ight=Chat+Hack

Down the thread about 4 or 5 replies is a response by Tom. Thats the one I used. It incorporates your process, and some additional parts to get it all working.

Stasik · #**141** 08-15-2001, 03:37 PM

yes, byt it works fine without other parts, too

It is not a VB3 engine, just a parsed copy!
