v2: Simple Press importer, and first thoughts

  • I’ve been playing with bbPress v2 for a little while now, primarily to see how easy it would be to write an importer from Simple Press. I’m sure that bbPress is going to need importers if the adoption rate is to be significant. Here are some initial thoughts:

    (1) It’s easier than I thought – largely because of the v1 import file.

    (2) We need a bbPress equivalent of wp_insert_pages, so we can call a single function, instead of creating pages, then adding lots of metadata – it’s not always clear what metadata is required, either.

    (3) In addition, it would be even better to ship with a generic import file that plugins could either modify, or plug into.

    For what it’s worth, here’s my very basic Simple Press importer. There’s no UI, error-checking is poor, and it doesn’t migrate stickies or notifications yet. You also have to update the counts from the Tools menu afterwards. And sometimes it dies through a timeout or OOM, but if it does, it should pick up where it left off. It’s a proof of concept, not a finished product, and is intended to encourage other developers, rather than for end-users. But it does work – at least for me. I may or may not develop it further, so if anyone else wants to, feel free!

    Hi AlexKramer,

    Sorry but i can’t find the way to use the plugin. Would you mind to post a little instructions on its usage? I only know how to paste the code in a txt file, renaming as php, zipping and installing as a plugin.

    And where to paste the code lines of your previous post in the plugin, please?

    I’ll be very grateful if I really can import my forum.

    Thanks in advance.

    Ok. I’ve activated the plugin and executed “http://site.com?bbpressimport=1&delete=1&#8221; where “site.com” is the URL of my WP installation.

    The conversion lasted less than a minute for approx. 1500 posts and had completed succesfully and with no errors. My SPF version is 4.4.1.

    Congrats for the plugin.

    This is plugin for import from “Simple Press forum” to bbPress-wp-plugin.

    Please help make same, but for import to independent bbPress-forum.

    It possible?

    At least one example how i can write into the bbPress database?

    Plugin worked brilliantly, thank you so much. Really saved a bunch of time and stress.

    Just a side note – Sermon Browser is also awesome, so thank you again!

    You. Are. AMAZING. Thank you so much for this plugin! I’m a debut author, and Simple:Press has given me nothing but headaches. I didn’t know how I was going to preserve what forum structure and posts there were – thought I was going to lose everything. You totally saved my neck. 😀

    I have created a ticket in trac https://bbpress.trac.wordpress.org/ticket/2074
    If you could keep all bugs and/or feedback posted to this ticket (‘tracs’ everything in one place)

    This has only beeen tested using Simple Press 5.1.4

    To install download the SimplePress5.php file and upload it to bbPress in the folder /wp-content/plugins/includes/admin/converters/

    Basic instructions on using any of the import tools are here (will to get these updated soon)

    Bro! Alex Kramer! You are awesome. That plugin did indeed work brilliantly. Thanks again.

    Changes for version 0.3
    * Check user capability
    * Convert user subscriptions
    * Convert Simple-press groups to bb-press category forum
    Usage example:
    http://site.com?bbpressimport=1&delete=1
    And of course make a database backup before converting.

    Hi, I hope it’s ok to ask my question here. I am trying to import about 175.000 posts, 11400 threads from simplepress 5.x to bbpress.
    All tables are in the same db, on the same server.

    It imported the threads ok, and the first 9000 posts. But after this the script seems to have a problem continue the import. It goes very slow.

    I have tried started again and again, and when I stop the script, and start it again – it imports about 50 before it stops importing – but it keeps running though.

    When I press Stop – I go to the Repair-tab in another browser-window, and reset the counting, then I go back and restart the import using “Delete all information from earlier imports” with 1 second delay, and 100 at the time.

    Still imports around 50 more, and then it stops. So now I am at about 17.600 posts. 10%.

    Will this not work for 175.000 posts? Am I doing something wrong?

    Server CPU is at 0%
