swifter_uk,

You are correct. The convertor does not affect your currently running IPB board. You can do the conversion as many times as you like.

One more question, is it possible to run the convertor to test it, am I correct to assume it does not affect the running of the existing software I am converting. I'd like to see how much work I have to do when I am ready for the final changeover, it will give me some idea of how much time to allow for the current board to be shut down.
yes the convertor does not affect ipb forum : it just reads data from it. hence you can run it several times without side effects.

So, finally i tried the conversion again with a simpler apache/vhost/directory-setup and it worked. So, yes, the setup probably was to blame. Sorry.

So far, a lot of things look nice (forums, posts, avatars, attachments...), but something is strange with some of the converted users: I can find (and edit etc.) some of my users using the ACP, but they don't show up in the normal member list of the board.

Some also didn't get assigned the right groups. Some just "lost" their group (and are only members of "Registered users" now, even though they had a group in the old IPB). Some were even assigned to wrong groups.

Some also seem to have the "hide my online status" preference set, even though they didn't have that set in the source IPB (although i'm not 100% sure on that one, since i haven't found out where IPB stores that setting in the db and all users can't access their control centers in the old IPB, which is one of the reasons for the whole conversion...). This seems to affect a lot (all?) of the users that also have the other problems mentioned. So it could be connected...

Strangely, it does not seem to affect all users, just a subset. So far, i haven't found out what distinguishes them... If there's anything i could do (i could e.g. provide some db dumps) to help with debugging this, i would be glad to do it. I have set up a copy of the old board and the new board on a separate testing server now, so i can try out anything.

well seems rather odd an issue :)

if you could provide with a db dump that would help obviously :)

btw are you using a standard ipb13 or a patched one ?

Yes, it does seem rather odd... The sooner i can throw away the old IPB board that is causing all this oddity (not only the conversion, it has a lot of other problems), the better...

I have kind of "inherited" this board, so i'm not completely sure what has been modified in it. I am sure of at least two mods, one for having a user picture separate from the avatar and one for having custom fields in the profile. But i don't really care that both are probably lost in the conversion process, having the basic user/group/board setup converted completely is all that i am hoping for. And we are using a german localization, but that shouldn't change anything in the db. Apart from that, it's probably a pretty standard IPB "v1.3.1 Final".

I'll send you a PM with details on the DB dump.

Thanks for all the effort, again! :)

Well I spent tonight giving this converter a go and through a little hoop jumping to get my DB migrated from 4.0 to 5.0 I seem to have the "pre-conversion" issues out of the way but now after I finally get to the third stage of "conversion in progress" but just a few seconds after clicking the "continue conversion" button I am quickly stopped by the following error.

Code: Select all

[phpBB Debug] PHP Notice: in file /install/convertors/functions_ipb13.php on line 1234: filesize() [function.filesize]: Stat failed for ./../../forum/uploads/post-7-1119757780.ibf (errno=2 - No such file or directory)
Can anyone shed any insight on how to bypass this? If I check my /uploads/ directory through FTP there is no "post-7-1119757780.ibf" file like it errors on so I see why it is stopping it but if its just an attachment I don't really care if it isn't converted.

Well I finally got round to setting up a new phpBB3 board and running a test conversion of our old ipb1.3 forums, all seems to have gone fairly smoothly on the conversion apart from one issue I have noticed so far.

When I view the board index page, last post's in all forums are stuck at 2005? However going into each forum the correct up to date topics are there. You can view what I mean here http://retiredgreyhounds.info/phpBB/index.php

I also was required to request a new password, is that normal and will it be the same for all of our members?

hi maat,
today i've used your converter to convert my board from IPB 1.3.1 to phpBB3 and it worked very well.
actualy it seems that the only missed things are the quote message.
i've seen your code and i've found that it doesn't work if the format date contains one or more character "-" (minus).

my message:
$message = "<!--QuoteBegin-Clomax+10-02-2010, 13:30--></div><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>QUOTE</b> (Clomax &#064; 10-02-2010, 13:30)</td></tr><tr><td id='QUOTE'><!--QuoteEBegin--> sasa <!--QuoteEnd--> </td></tr></table><div class='postcolor'> <!--QuoteEEnd--><br> non va ";

your code:
$message = preg_replace("/<!--QuoteBegin-[^-]+--><\/div><table [^>]*><tr><td><b>QUOTE<\/b> \(([^\)]+)\)<\/td><\/tr><tr><td id='QUOTE'><!--QuoteEBegin-->/siU","[quote=\"\\1\"]\r\n",$message);

my code:
$message = preg_replace("/<!--QuoteBegin-.+--><\/div><table [^>]*><tr><td><b>QUOTE<\/b> \(([^\)]+)\)<\/td><\/tr><tr><td id='QUOTE'><!--QuoteEBegin-->/siU","[quote=\"\\1\"]\r\n",$message);

the problem:
<!--QuoteBegin-Clomax+10-02-2010, 13:30-->
<!--QuoteBegin-admin+Jul 7 2008, 04:19 PM-->

the question is: why you have decided to filter the minus character?

Hi All!
I'm a bit late to the party for converting IPB 1.3 to phpBB 3.x and after many attempts at failing (realised I was using IPB 2.x convertor thinking that's what the old board was) I got the correct convertor and it started converting, but quickly came up with first error as follows.

Code: Select all

[phpBB Debug] PHP Notice: in file /install/convertors/functions_ipb13.php  on line 1234: filesize() [function.filesize]: stat failed for ./../../testforum/uploads/post-8-1076568855.jpg
It lists this code several times - 14 times actually all with different post-8-xxxxxxxxxx.jpg

Line 1234 of the functions_ipb13.php is

Code: Select all

	return filesize($convert->options['forum_path'] . '/uploads/' . $attachement_filename);
Can some one help solve this problem?
I noticed JReese above had a similar problem and no answer came.

Please note I am a little bit of a novice at all this, but I can change codes in php files using PSPad!

Thanks!
Ollie

What is the address to your phpBB board and what is the address to your IPB files?

IPB and phpBB have to be in different directories. You should never install a program into a directory where another program exists. Files of the original program are likely to get overwritten by the new program so that now the original program no longer works.

For those looking for a proper authentication file for IPB 1.3, i have written one that puts the passwords through the crazy clean_value function of IPB so that passwords with special characters in them still work correctly.

save this file as includes/auth/auth_ipb13.php
