In WordPress is pretty simple create custom roles and also assign specific capabilities to specific user roles (no matter if from core or custom). In my plugins I often create an user role that has all the capabilities required by my plugin, and then I attach some of thos capabilities to existing roles. I’ll give … Read more
Retrieve user_meta and copy to post_meta
First of all get_users_of_blog has been deprecated, so you should use get_users instead, or run a WP_User_Query. After that, the_author_meta echo the meta value, not return anything. To return the meta you should use get_the_author_meta() $blogusers = get_users( $args ); // for args see codex if ($blogusers) { foreach ( $blogusers as $bloguser ) { … Read more
Let user select their own category
User taxonomies can help you achieve this, I’m working on something similar. You can install the plugin http://wordpress.org/plugins/user-taxonomies/, and register a custom taxonomy , although in my case the plugin has some limitations, may be it helps you. register_taxonomy(‘profession’, ‘user’, array( ‘public’ =>true, ‘labels’ =>array( ‘name’ =>’Professions’, ‘singular_name’ =>’Profession’, ‘menu_name’ =>’Professions’, ‘search_items’ =>’Search Professions’, ‘popular_items’ … Read more

SELECT from wp_users, get Displayname too

One key thing to note here, is that I aliased dbold_posts as P, and dbold_users as U – when dealing with multiple table, it’s always best practice to specify which table you are referring … Read more
Can user meta be shown or hidden depending on user logged in status?
The way you suggest doing this, it won’t ever be secure. If I understand you, just disabling Javascript would spoil the security. What you’d need to do is run a script that uses an AJAX request to query for and then add data to the page, but only if the user is logged in. That … Read more
Parsing a shortcode through an author meta textfield
the_author_meta() is going to echo content directly. It will not pass a string back that can be processed by do_shortcode(). You want get_the_author_meta(), which is essentially the same as the_author_meta() but it returns a string instead of echoing the data.
using update_user_meta to rank users
It looks like the plugin is using the update_post_meta function, which in turn uses the update_metadata function which includes the action hooks update_postmeta and updated_postmeta which fire immediately before and after the post meta is stored to the database. You could hook into one of these to update the user meta of the author of … Read more
