You are arranging the users within foreach block. Why don’t you arrange them first and then go with the loop for displaying info. If you do that, you will need only one query. Do this in this order- 1. Do the query with get_users. You can add an extra parameter who=author. This will force to … Read more
There are various ways to do this, but I’ve recently addressed a similar problem by using cookies. add_action( ‘init’, ‘wpse_93797_cookie’ ); function wpse_93797_cookie() { if ( !isset ( $_COOKIE[‘wpse_93797_cookie_name’] ) ) { // Do your stuff. // Set your cookie so we don’t do stuff the next time around. // Note that 0 makes the … Read more
Always use the existing functions, if those functions do what you need. That way, your code has the best chance of staying functional as the Core changes. If you make direct queries to the database then you have to keep track of changes to the database and alter your code accordingly. Using Core functions also … Read more
After a lot of trial and error I learnt that WP_User_Query takes an argument fields which can be set to ‘all_with_meta’. This reduces number of queries to two for any number of users that are fetched in a single go and also provides benefits of caching. Usage would look like: $user_query = new WP_User_Query( array(‘include’ … Read more
I wasn’t sure if you meant users or commentators, so I took both. SQL The email is saved in $wpdb->comments in the column comment_author_email for comments. It is saved in $wpdb->users in the column user_email for users. To get the domain part from the email in comments, we can use: SELECT ( SUBSTR( `comment_author_email`, INSTR( … Read more
A combination of user_register and wp_insert_post should work fine: add_action(‘user_register’, ‘create_postset’); function create_postset($user_id) { // userinfo $user_info = get_userdata($user_id); // Create post objects $post_1 = array( ‘post_title’ => ‘1st post created for ‘ . $user_info->user_login, ‘post_content’ => ‘Lorem Ipsum’, ‘post_status’ => ‘publish’, ‘post_author’ => $user_id ); $post_2 = array( ‘post_title’ => ‘2nd post created for … Read more
You have a few options. Either give your post type a custom permission or work within the existing permissions (such as post) In my opinion the best way to go about this would be to set a custom capability type when you register the post type. A good one to use in your case may … Read more
To remove the Add Users capability from Administrators (but leave it intact for Super Administrators), you can do this: <?php $role = get_role( ‘administrator’ ); if ( $role->capabilities[‘add_user’] == 1 && ! is_main_site( get_current_blog_id() ) ) { // Because this is saved to the database, we check first // to see if it’s already been … Read more
This is not working and also I don’t know how can I get the comments of the current user. You have already used the current user’s ID in your code… echo ‘User ID: ‘ . $current_user->ID; … but you hard-code a single ID in the get_comments argument array. Don’t do that. Use the current user … Read more
Is there a way to let the users edit their usernames? no. I think you summarized nicely why this should not be easily possible, since a change of user name will change the URLs of pages in the site something that only an admin should be able to do. Of course you can write a … Read more
