1. Install Question2Answer
2. Get the source code for this plugin from github, either using git, or downloading directly:
   • To download using git, install git and then type git clone git:https://github.com/NoahY/q2a-badges.git badges at the command prompt (on Linux, Windows is a bit different)
   • To download directly, go to the project page and click Download
3. Go to Admin -> Plugins on your q2a install and select the 'Activate badges' option, then 'Save Changes'.

The translation file is qa-lang-badges.php. Copy this file to the qa-lang/<your-language>/ directory. Edit the right-hand side strings in this file with notepad2, notepad++, etc. (don't ever use Window's Notepad. For anything. Ever.), for example, changing:

'good_question'=>'Good Question',

to

'good_question'=>'Swali nzuri',

for Swahili. Don't edit the string on the left-hand side or bad things will happen.

Once you've completed the translation, don't forget to set the site language in the admin control panel... to Swahili.

Custom badges may be implemented in any plugin module in a similar way as option_default. Steps are as follows:

1. create a function in your module class called custom_badges(). It should return an array of badges with the badge slugs as indexes for nested arrays with var (default requirement) and type (bronze=0,silver=1,gold=2) indexes. Here is an example from the comment-voting plugin:

function custom_badges() {
        return array(
                'nice_comment' => array('var'=>2, 'type'=>0),
                'good_comment' => array('var'=>5, 'type'=>1),
                'great_comment' => array('var'=>10, 'type'=>2)
        );
}

2. create a function in your module class called custom_badges_rebuild() that will award badges when rebuilding via admin/plugins and return the number of badges awarded. Here is an example from the comment-voting plugin:

function custom_badges_rebuild() {
        $awarded = 0;

        $posts = qa_db_query_sub(
                'SELECT userid, postid, netvotes FROM ^posts WHERE type=$ AND netvotes>0',
                'C'
        );
        while ( ($post=qa_db_read_one_assoc($posts,true)) !== null ) {
                $badges = array('nice_comment','good_comment','excellent_comment');
                $awarded += count(qa_badge_award_check($badges,(int)$post['netvotes'],$post['userid'],$post['postid'],2));
        }
        return $awarded;
}

3. implement qa_register_plugin_phrases() via your qa-plugin.php, including two entries for each badge: badge_<slug> and badge_<slug>_desc. Here is an example from the comment-voting plugin:

return array(
        'permit_vote_c' => 'Vote on comments',
        'badge_nice_comment' => 'Nice Comment',
        'badge_good_comment' => 'Good Comment',
        'badge_great_comment' => 'Great Comment',
        'badge_nice_comment_desc' => 'Comment received +# upvote',
        'badge_good_comment_desc' => 'Comment received +# upvote',
        'badge_great_comment_desc' => 'Comment received +# upvote',
);

4. Create your own mechanism for awarding badges - see some examples in the badges plugin code, or the bookmark plugin. Make sure to test for both qa_opt('badge_active'), which makes sure the badge plugin is active, and qa_opt('badge_custom_badges') to make sure the badge plugin version supports custom badges. Use the function qa_badge_award_check() to check for badges, where $badges is an array of badge slugs, $var is the number to test against the badges, $oid is the postid (if any), $notify = 0 for no notification, 1 for email and popup, 2 for just popup. You should probably check if this function exists as well, in case the badge plugin has been deleted while active.

This is beta code. It is probably okay for production environments, but may not work exactly as expected. Refunds will not be given. If it breaks, you get to keep both parts.

All code herein is Copylefted.
