SMF Import to bbPress

  • Introduce Forum Importer template for use with importing from SMF v2.0.x(Tested on v2.0.4)

    http://codex.bbpress.org/import-forums/ & ​​http://codex.bbpress.org/import-forums/smf

    Working: Forums, Topics, Replies, Users & User Passwords
    Partial: Custom BBCode for Topic & Reply Content
    Not Working Yet: Categories

    Attached to bbPress Trac Ticket #2380 is the 1st pass patch for SMF importing into bbPress.

    To test the importer download the latest patch from the link above and copy/ftp the file into the /includes/admin/converters/ folder of your bbPress plugin.

    I hope to get the remaining outstanding items done ASAP.
    (User passwords will be a little trickier and will take a bit more time)

    Any feedback and/or testing that you can provide will help me out tremendously.

    Cheers,

    Stephen 🙂

  • Mike, thanks, much appreciated.

    I’ve copied and pasted it into a GitHub Gist here:
    https://gist.github.com/ntwb/9ff3f1ed93ae9671a93b

    It makes it much clearer to read and update, if anyone wants to make improvements or suggestions drop a comment on the Gist 🙂

    This is a great start and I hope to one of these days get attachment importing into bbPress importer 😉

    Hi again,

    Here is an improved version of the SMF to bbPress script. This version supports additional, non-image filetypes, and has more safeguards against inserting attachments multiple times if the script is interrupted and restarted. Since I am not yet savvy in the ways of submitting source code to the forum, I am cutting and pasting, which seems to butcher the syntax horribly…

    Many thanks, again, to Stephen.

    Another script – this one cleans up the messy duplicate attachment references to the same media entry that were left behind, should you happen to re-run the older version of the script. Hopefully
    you will not need this, but I certainly did after developing the script and running it dozens of times! – Mike

    Is there a way to use this importer for the latest version SMF 2.1 Beta 1? Please help me, because I want to use bbPress. I have over 20,000 registered members and this is a big problem. SMF has become a very bad solution.

    @kweh, I’ll update the SMF importer once the full v2.1 is released, we won’t be supporting the 2.1 beta, if you’ve upgraded from 2.0.x to 2.1 beta I’d look at seeing if you can downgrade back to 2.0.x and import from there.

    Hi Stephen,

    I’ve made some slight improvements to the attachment importer script – pls check with me when the time comes, and I’ll send you the latest version. I have looked around for how to get write access to the source repository, and still don’t have a clue.

    Looking over the SMF->bbPress import template, I noticed that avatars are being imported from the wrong place – they actually live in the attachments table, not the avatar table, with the associated ID of the user.

    All the best,

    Mike

    Hi Stephen! Thanks for all of your volunteer work on this, I greatly appreciate it. 🙂

    Just a few questions, and I did do a few days of research (with no luck) before asking.

    1.) Any plans to support importing of private messages? I plan to use BuddpyPress + bbPress, so the feature will be covered. What are the chances of adding another checkbox to “optional settings” that says “Attempt to import private messages to BuddyPress”

    2.) I have noticed that my existing SMF database had a handful of deleted accounts, so my settings left those posts behind as “Guest” posts (and it displayed the deleted user’s old username). In WordPress + bbPress, I created the original admin/keymaster user in my fresh install. After doing the SMF to bbPress import, the “Guest” posts from the deleted account are automatically assigned to the existing admin/keymaster user that I created in WordPress. Is there a cleaner way to handle this default behavior? Do these posts from deleted accounts require being assigned to an account? If not, could I somehow mass re-attribute these posts to a different account?

    Hi timsilva_

    We have the same issue.
    SMF = we have created a user : “Guest” All the posts were attribute to “Guest”.
    Import = a new member “Guest”.

    The other solution:

    If “keymaster” has no post
    Create an account “guest”
    Create a new “keymaster”
    Delete the previous “keymaster” attribute post to guest.

    Any plans to support importing of private messages?

    Yes, I want to, I just haven’t worked out the best way to do this 🙁

    2.) I have noticed that my existing SMF database had a handful of deleted accounts…

    All of your questions in regard to this point ship in bbPress 2.6, with a few more not yet mentioned. 😉

    I got the problem, that the importer can´t handle “ä”, “ö” and “ü” from my german board.
    How can I change this? Is there a fix available?

    They are displayed like this “Ankündigungen” instead of “Ankündigungen”.

    I had fundamentally wrapped up a converter format for smf 1.1.8 when I went over your post and your script. Uplifting news is it would appear that I got really close.

    I might want to see better what the authenticate_pass capacity should do. On the off chance that it is simply expected to return genuine if the present client’s watchword coordinates the old smf hashed secret word then it appears that I ought to have the capacity to utilize a capacity like ssi_checkPassword that was incorporated in the SMF ssi.php script, accepting that the sha1 capacity is accessible.

    @donchulio Adding a topic titled Ankündigungen with the topic content Ankündigungen and a reply with content Ankündigungen works as expected for me with bbPress 2.5.8

    Screen Shot

    Can you check what character set and collation both your source SMF database is and also the same for your WordPress database?


    donchulio
    Participant

    @donchulio

    Hi Stephen,

    sorry if I am a newbie in this but where can I check this exactly?

    If you open up phpMyAdmin which I presume you’ve most likely got installed on your webhost and then open the SMF database and then open the smf_messages table then click ‘sql’, copy and paste this into the query box and click “Go” (The Go button is at the bottom right)

    
    show variables like 'character_set_database';
    show variables like 'collation_database';
    

    You should see something like this https://cloudup.com/cluBnqdtz4x

    In my case the character set is utf8 and collation is utf8_general_ci


    donchulio

    @donchulio

    I don’t know why, but the value is “latin1”. How can I change this?

    Which one is latin1? Having both these values would be helpful so I can test it please 🙂


    donchulio
    Participant

    @donchulio

    It is in: “character_set_database”.

    What about collation?


    donchulio
    Participant

    @donchulio

    I think a Screenshot is easier: http://abload.de/img/imageyyq0e.png

    @donchulio Thanks, strange the collation isn’t there, but anyway, I’ll create an SMF test site using latin1 and see what results I get 🙂
