Is there any badges system

I think he meant to append some kind of badges to user’s profile (next to send private message or add friend, or in that area), which I am also looking for this 🙂

I think if we have some sort of achievement taxonomy in place, you’d want to show the last achievement earned within a chosen taxonomy. Could be levels, ranks, titles, etc.

Without a taxonomy, I think the last badge earned is a good default.

Thanks for the disclaimer Mike, and for your contributions.

I’m working up a beta for my project to test internally in May/June, so even rough/buggy code is helpful to give my testers an idea of what kind of functionality might be possible, even if it gets reworked by you/Paul later.

Making some progress … able to select and store badge. Next step is to retrieve selected badge and display it in comments. Code is still too rough to post, should have something tomorrow though.

PS: Thanks, Paul! Glad you like it … assumed it was already in use so didn’t think anything of it. 🙂 hehe

Quick status update before I call it a night:
Completed Functionality so far:
– can specify badge manually.
– display badge next to page/post/comment author

To Do:
– select most recent achievement as badge from a specified category
– In the absence of categories, select most recent overall achievement as badge
– Show badge in profile

I should definitely be able to get this done by tomorrow evening.

OK, I’m almost there. The only thing not working is getting the latest achievement from a badge-enabled category (any help on how to construct a WP_QUERY to filter on custom taxonomy custom fields is appreciated!).

Step 1: if you have used my achievements category “hack”, be sure to remove the dpa_achievements_add_profile_fields_with_categories() from your functions.php file in your child-theme first.

Step 2: add the following code to your functions.php:

/* Group Achievements by Category in User Profile and Select Badge ************/
	function dpa_achievements_add_profile_fields_with_categories($user)
	{
//		if (!is_super_admin()) {return;}

Step 3: Customize dpa_achievement_comment_with_badge() to format your comments as needed.

Step 4: If you don’t have comments.php in your child-theme, go ahead and copy it there from your current theme.

Step 5: Edit comments.php in your child-theme by replacing the existing wp_list_comments() with the following:
<?php wp_list_comments( array( 'callback' => 'dpa_achievement_comment_with_badge', 'style' => 'ol' ) ); ?>

Conclusion: This code should add the following:

• Badge Selectors on User Profile admin page for both SuperAdmin and User.
• Designate achievement categories (if you have them implemented) to be badge-enabled. Do this by modifying existing categories, or making the selection for new categories. The selection will save, but I still need to work on the selection process.
• Display the most recent achievement as the badge if there is no badge selected for the user.
• Display badge next to user’s avatar in comments and author info.
• Added function dpa_get_achievement_badge($user_id, $size) and dpa_achievement_badge($user_id, $size) to allow you to insert the badge whereever you like in your theme.

Please let me know if you’re having trouble with this — I know it’s a lot of code. Also, I’d be interested in seeing your results, post your links here! 🙂

Happy coding!
