Fixed a problem with tables appearing at the bottom of the site

Mon, 26 Sep 2022 13:23:48 +0000

This problem appeared on my site when it was transferred from one hosting to another. The customer success team reported that the reason lies in a defect in the database. What do you think about that and what are the proposed solutions and your opinions about the cause of the problem. Let's discuss it.

Strange part of Q2A. Why qa_postmetas table is seperate ?

Sun, 04 Oct 2015 22:14:36 +0000

I don't have a lot of experience in data storing but here is my note, maybe someone can clear things up...

qa_postmetas looks useless if extra field is not used wich can be stored in qa_posts in my opinion.
Extravalue doesn't work with external php code. Problem with no answer to solution>
Emty rows are created with post id and stays even if question is deleted.

Size of contentwords table

Thu, 16 Jul 2015 06:48:10 +0000

What is a reasonable size for qa_contentwords?
Is there a way to limit the size somehow?

I am aware there is no answer like XYZ MiB, but for example my current question2answer site has 10,452 estimated entries (phpmyadmin) in contentwords with a size of 4,3MiB or 4,5MB and qa_posts has 592 KiB, qa_words 448KiB. Is this a reasonable size or is something maybe flooding my table with spam? Are these still reasonable ratios?

I ask because the site is under constant spam, flooding and botnet attacks with thousands calls a day since it got listed in some spam provider after the flyspray bug report tool had a security leak and after that the mediawiki I hosted there. Once you are listed, you get a lot of scans and attacks :D

Where can I find documentation about the tables and fields?

Sat, 21 Dec 2013 14:59:41 +0000

I would like to understand what each field of each table does. Possible values for each of them would also be very useful. Where can I find this documentation?

Using existing user tables

Sun, 04 Aug 2013 00:32:29 +0000

I was wondering if there was a simple means of using an existing table containing the user ids, passwords, avatars etc.. I looked through the login system and it seems to be a very labour intensive task to integrate pre-built tables to the question and answer system itself.

The situation I'm in is that I have already build a functioning site for user interaction, profiles etc and so I would like to maintain this and simply integrate the question and answer system around it. Understandably I could build such a system from scratch but I would like to consider all the options prior to resorting to this.

It's currently being run on my local server however, I will publish it on a main site if the integration is feasable and practical. It seems the most affective way of finding it out would be to ask here.

qa_postmetas Table: Why adding record if empty

Sun, 07 Jul 2013 14:58:47 +0000

Just wonder why it is creating record for qa_q_extra in qa_postmetas even if field is empty. Isn't that better to add record only if question has qa_q_extra value? Or any reson to store empty record? Just curious to know.

Why empty tables in database (qa_postmetas, qa_tagmetas, qa_usernotices)?

Fri, 24 May 2013 07:49:05 +0000

By curiosity, which of these tables (having 0 rows/entries) can be considered unnecessary?

I know that some were created by plugins, some are there be default:

qa_categories ← I am not using categories, that's why this is empty.

qa_categorymetas ← same

qa_messages ← I am not using PN that's why this is empty.

qa_postmetas ← what for?

qa_tagmetas ← what for?

qa_usermetas ← "Plugins etc... can use qa_usermetas for any meta information relating to users - see qa-db-metas.php." Clarified.

qa_usernotices ← what for?

How to handle non-existing tables before init_queries was run?

Tue, 08 May 2012 12:49:52 +0000

I spotted the notes about init_queries in the docs, so in a new plugin I decided to use that function to initialize a database table.

Problem now is, in my admin_form function I try to select from that table, so when a user adds the plugin then opens Admin>Plugins, they get an error about the table not existing.

The "Initialize Database" button is there and works fine, but is there a better way to handle this?

with QA_EXTERNAL_USERS = true install ends in loop - missing tables

Tue, 06 Mar 2012 16:23:29 +0000

I just downloaded Q2A to install with QA_EXTERNAL_USERS set to true

I did as it says here: http://www.question2answer.org/single-sign-on.php , with qa_get_mysql_user_column_type returning 'INT' and everything seems to be well. When I fire up Chrome and go to the right subfolder it says a lot, and ends up with at button that says [Create Database]

I click that button and it tells me a lot of good stuf with green text and ends up with a link that says "Go to admin center". When I click that I return to [Create Database] I can't get out of this loop.

What I figured out is, that the database-creation seems to miss out on 5 tables:

brygbaren_qa_messages
brygbaren_qa_userfields
brygbaren_qa_userlogins
brygbaren_qa_userprofile
brygbaren_qa_users

I really can't seem to figure out what is causing this. Plz help, I'd love to use this stuff ;)

How to upload a category dump ?

Thu, 07 Jul 2011 21:42:34 +0000

Hello and congrats to the final release !

I am wondering if it would be possible to upload a category dump.

Which tables would be affected ?

And in a second step:

If I want to add to each created category one or two basic questions, which tables would I have to modify that for ?

And finally: How many categories should I use at most.

The project is a regional questions site.

Thank You for any ideas or hints
