Where i can find answers content and in which table ?

Tue, 01 Dec 2020 08:35:42 +0000

I am looking for an answers table. Where all answers are stored in the database?

The qa_post table is available there but in this table, I can see the question title and content without any answers content.

Tell me the answers table name or reference?

Would it be safe for me to completely empty and re-index the contentwords table?

Do I have to do this because it exceeds 500 mb?

Adding a table to make a top-posters' list that cycles every 24-hours!

Wed, 13 Apr 2016 23:08:09 +0000

Without losing the ability to reasonable easy upgrade, when new versions of Q2A are released, how difficult is it to create a new table that is accessed for a new feature I develop? I realize the naming need be something statistically improbable to ever be used by the Q2A core!

(If an upgrade [to Q2A] may potentially mess with the table, then would creating a separate database be better?)

There are several things I have in mind, but one, for example, (that could be done other ways, but this seems the most efficient w/a large database and many users OL @ a given time) is to show the individuals w/the highest number of posts w/in the past 24 hours. Now, the past 24 hours, clearly doesn't mean at midnight the whole thing is just reset! Rather, If member-1 posts one question at 3am, one answer at 6pm and another answer at 1 am the next day, they will be listed all of the first day from 3am on (unless they are pushed off the bottom of the 'stack' of, say 10 listed 'top-posting members' showing "1 post" between 3am and 6pm, where it would become "2 posts" until 1 am the next morning, where it would read "3 posts". Then a few hours later at 3am, the 24-hour time will have expired on the first post, thus it would read "2 posts" (assuming they post no more), and at 6pm it would similarly decrement to "1 post" and assuming nothing new was posted by 1am the following morning, they would drop off the list (assuming they even had made to to the top ten 'top-posters' somewhere along the line!

I simply though each new "post", meaning: Q or A, could place an entry into a table with the userID, the timeDate (either of post time or of expiration time), then anytime the page was loaded, it would use this relatively small table to, first, delete any expired posts from that list, then, assemble the list determining a post-count for each user in the list, and, finally, see who makes the top ten cut, and then display those on the current page. (I suppose ties can be broken based on who had the earliest post or something trivial like that.)

Is this a reasonable solution to work out what I'm trying to do, or what better advise/corrections can you provide? Am I warm?

Thank you for taking the time to read my explanation!

In which table all the answers for a question are stored?

I didn't find it in the qa_posts table.

What is the purpose of the table qa_sharedevents?

Adding a custom column to table qa_posts dangerous?

Sun, 16 Nov 2014 16:03:29 +0000

For another plugin I only need to set a flag for each question (0, 1 or 2).

For now, I am going the "clean" way to create another table that holds the questionid + the flag.

However, for several mysql requests it would be nice to get the flag directly from qa_posts, because then it is only a one liner.

Consequently my question is:

What happens if I add an extra field to qa_posts? Will there be any update problems (let's say I give it a name like q2apro_flags, should this be a problem)?

Thanks in advance for your advices,
Kai

About allowing uppercase to table name in V1.7

Wed, 29 Oct 2014 00:43:48 +0000

Now, table name (include prefix) is limited in lowercase. Uppercase may be allowed to the database table in V1.7. I think this change is mistake.

https://github.com/q2a/question2answer/commit/a52cf400acb3fa132134d6739bf40baf94c27faf#diff-956d4bd1a1cac02a9a381ffc25913c20

Because ...

It becomes incompatible between operating system (Linux, Windows, MacOS, etc), and Q2A becomes none-cross-platform system.
WordPress and Drupal convert table name to lowercase at installation.
Various problems happen when uppercase is admitted for table name.
https://wordpress.org/support/topic/case-sensitive-wp_table_prefix?replies=1
http://stackoverflow.com/questions/9827164/wordpress-keeps-redirecting-to-install-php-after-migration
etc, etc
As for this change, this thread and this seem to become the basic point. This is issue of specific plugin. And not issue of Q2A core.

How do you think about this?

Core bug: colspan of wide table (?)

Sun, 10 Aug 2014 21:52:02 +0000

In the course of HTML validation test of FlexArmor2, I found a small bug(?) in the base theme.

form_columns()
form_field_rows()

Before:

colspan = 3

After:

colspan = 2 ?

Can I delete queued posts directly from the mysql table?

Mon, 16 Jun 2014 08:09:54 +0000

It's very annoying to manually hide and delete posts that are marked as spam by akismet spam filter. akismet just put the posts into the moderation queue. So my question is, can I simply delete those entries from the qa_posts table or are there correlations to other tables, that would cause problems?

Manipulating FORMs in Q2A that are created by arrays?

Tue, 23 Jul 2013 11:39:28 +0000

There is a FORM element created using arrays*, I get this output:

<FORM id="qa-user-history-main">
    <TABLE CLASS="qa-form-wide-table">
        <TR> ...

Now I want to give the first <TR> element (and others that I pick!) a css class name, how do I do it?

*The form is created by:

        return array(
            'style' => 'wide',
            'title' => qa_opt('user_act_list_title'),
            'fields'=> $fields,
            'tags' => 'id="qa-user-history-main"',
        );

see qa-history-layer.php → https://github.com/NoahY/q2a-history/blob/master/qa-history-layer.php

Get questions, answers and comments by user emaiID rather than UserID?

Wed, 17 Jul 2013 01:50:49 +0000

I am developing plugin which allows WordPress integreation on Running Q2A Site. Now concept is not so difficult but one complication I found is transfering Q2A users.

Where all content identify by userid ( ofcourse ) this can give real trouble while merging WP users and Q2A users in same table.

If I auto increament Q2A user id in WP table than it will creates great trouble to identify the content and of course everything will messed up.

Any idea suggestion?

What exactly happens, if one empties qa_contentwords only ?

Mon, 08 Jul 2013 04:56:51 +0000

A) qa_contentwords is growing too fast, which funtions of q2a wouldnt work anymore if one empties this table ?

I understand that search wouldnt work ?

B) Could the table qa_contentwords be reduced to use only the words of questiontitles for search? Which function would one have to change how ?

(Iam working on a page with 200.000 localities in 60.000 categories on 4 levels, performance is brilliant, reindexing fast, surprisingly stable. The only problem is that the qa_contentwords table uses half of the total database space.)

Two questions regarding table "qa_cookies"

Wed, 09 Jan 2013 04:17:27 +0000

I would like to know more about qa_cookies. Example entries:

cookieid	created	createip	written	writeip
1616998859625367400	2013-01-09 09:10:52	1351659518	2013-01-09 09:10:52	1351659518
17762331686246191714	2013-01-09 01:11:32	1558524896	2013-01-09 01:11:32	1558524896
16769361733673514866	2013-01-09 00:11:43	1419461695	2013-01-09 00:11:43	1419461695
17246418231037538345	2013-01-08 22:56:03	1575265698	NULL	NULL

How are the columns used?

cookieid → clear, saves the generated cookie-id to identify the user

created → time of creation

creatip → recent IP of the user (?)

written → ... ?

writeip → ... ?

This question is actually related to the headers-already-sent-bug (badges plugin), as the last entry in the table above with NULL | NULL was giving me a server error. Badges plugin called: qa_cookie_get_create()

Thanks,
Kai

My Own Header Above Q2A

Sat, 08 Sep 2012 11:54:31 +0000

Hi. I have done this with other programs on the net, where I simply put some html code in somewhere, and I am able to make a table header, so that I can have my own header.

Problem is, that I don't know where I should put the html code in QtoA..

Which file would I put the code into?

After which line of code, would I put the html, to make my own header.

I need the header to be displayed on every page.

Thank you. (this is really simple. I just need to know where to put the html code)
