There’s the WP_User_Query for that: /** * List all Users * Use as: Template Tag * * @uses WP_User_Query * @return (array) List of user objects */ wpse35713_get_users_list() { $query = new WP_User_Query( array( ‘order’ => ‘ASC’ ,’orderby’ => ‘login’ ) ); $users = $query->get_results(); $html = “<ul><li>”; foreach ( $users as $user ) { … Read more
The last parameter of update_user_meta(), the previous value, is an optional parameter. If it’s set it checks whether the value in the database is indeed the one you fed update_user_meta(). If you set that paramteter by grabbing the value from the database, it is completely redundant. So first off, omit that. That being said, this … Read more
There’s wp_login_form() for such cases. It offers tons of hooks to extend it. // In your template wp_login_form( array( /* Args: refer to Codex page */ ) ); A more in-depth look at the filters, can be found here @GitHub WP Core source. ‘login_form_top’ – above login-username ‘login_form_middle’ – above login-submit ‘login_form_bottom’ – below login-submit … Read more
As said in the comments, this depends on how many users there are and how different those menus are supposed to be. If there are just a few users and you want completely different menus for each of them, you would have to create different menus in the backend and the call them conditionally in … Read more
I would consider installing Jetpack and activating the Email Subscriptions module.
The hook you choose is appropriate, and here is how to use it to delete all posts of all types (posts, pages, links, attachments, etc) of the deleted user: add_action(‘delete_user’, ‘my_delete_user’); function my_delete_user($user_id) { $args = array ( ‘numberposts’ => -1, ‘post_type’ => ‘any’, ‘author’ => $user_id ); // get all posts by this user: … Read more
It was actually much easier than I originally thought – just doing a WP_User_Query for a meta value (meta arrays are supported as well, like for the other query classes). public function on_deactivate() { $meta_key = ‘tools_page_tsi_per_page’; $query = new WP_User_Query( array( ‘meta_key’ => $meta_key ) ); if ( empty( $query->results ) ) return; foreach … Read more
You can store the data in the user meta as an array of post-id -> comment count at last visit and then simply count the comments since that date, for example function get_user_comment_count_since_last_visit($user_id ,$post_id){ //only do this for logged in users if ($user_id <= 0 ){ return 0; } /** * get last comment count … Read more
assumes that your theme is using comment_class(); example (to be added to functions.php of your theme): add_filter( ‘comment_class’, ‘comment_class_logged_in_user’ ); function comment_class_logged_in_user( $classes ) { global $comment; if ( $comment->user_id > 0 && is_user_logged_in() ) { global $current_user; get_currentuserinfo(); $logged_in_user = $current_user->ID; if( $comment->user_id == $logged_in_user ) $classes[] = ‘comment-author-logged-in’; } return $classes; } requires … Read more
WordPress records when a user was registered in the $wpdb->users (usually wp_users) table in the column user_registered. So you can use that to calculate the average account age. There’s no internal function for this, so you’ll have to use $wpdb directly. This stackoverflow answer has some good info about calculating the average of a series … Read more
