Fastforward to WordPress 4.4 – it will support the role__in attribute! It looks like WordPress 4.4 is our lucky version number, because it will support both the role__in and role__not_in attributes of the WP_User_Query class. So to include the subscriber, contributor and author roles, we can simply use: $users = get_users( [ ‘role__in’ => [ … Read more
If you can stick to overriding just functions that are located in wp-includes/pluggable.php then you should be able to avoid any kind of plugin conflicts … unless you are using plugins that are overriding the same pluggable functions. Just make sure that your functions are declared before pluggables is loaded. Plugins are loaded before the … Read more
You can remove the default meta boxes with remove_meta_box and re-add them in a different position with add_meta_box: add_action(‘do_meta_boxes’, ‘wpse33063_move_meta_box’); function wpse33063_move_meta_box(){ remove_meta_box( ‘postimagediv’, ‘post’, ‘side’ ); add_meta_box(‘postimagediv’, __(‘Featured Image’), ‘post_thumbnail_meta_box’, ‘post’, ‘normal’, ‘high’); } The answer above is from the following thread: How to change default position of WP meta boxes? UPDATE If the … Read more
Yes, and no! The way users work in a multisite scenario is that there is a single pool of users, who are then associated with blogs. So, logged in status is common across all the blogs, but you can use is_blog_user($blog_id) to determine whether the current logged in user is a member of that blog. … Read more
get_current_user_id() give you the user id of the logged in user. And that is: you. You have to get all users: <?php $users = get_users(); foreach( $users as $user ) { $udata = get_userdata( $user->ID ); $registered = $udata->user_registered; printf( ‘%s member since %s<br>’, $udata->data->display_name, date( “M Y”, strtotime( $registered ) ) ); }
UPDATE 2018-06-28 While the code below mostly works fine, here is a rewrite of the code for WP >=4.6.0 (using PHP 7): function add_course_section_filter( $which ) { // create sprintf templates for <select> and <option>s $st=”<select name=”course_section_%s” style=”float:none;”><option value=””>%s</option>%s</select>”; $ot=”<option value=”%s” %s>Section %s</option>”; // determine which filter button was clicked, if any and set section … Read more
The other answers are correct, but it’s possible to achive the same thing with less code using wp_list_pluck(): $users = get_users(); $user_names = wp_list_pluck( $users, ‘display_name’ ); wp_list_pluck() used that way will get the display_name field of all the users in an array without needing to do a loop.
This allows plugins to easily hijack the default role while they’re active. // Hijack the option, the role will follow! add_filter(‘pre_option_default_role’, function($default_role){ // You can also add conditional tags here and return whatever return ‘subscriber’; // This is changed return $default_role; // This allows default }); I use it to make sure some plugins that … Read more
According WP database structure, ID in wp_users is Bigint(20) UNSIGNED, so you could “theoretically” add 18446744073709551615 users. http://dev.mysql.com/doc/refman/4.1/en/integer-types.html
The size of the table isn’t really the issue, the queries you’re running on that table might be. For example, if you’re selecting users based on data stored in the user-meta table, then that query will be highly unoptimized, because meta_value is not an indexed field. In which case you may need to add extra … Read more
