It’s not a good idea to store user’s data on a file that is publicly accessible. A better way would be to create a folder, and store your file under it. Also, it’s better to use WordPress’s filesytem class rather than directly using PHP’s built-in functions. Here’s a quick fix: function wpse381320_after_login( $atts ) { … Read more
wp_get_current_commenter() returns an array, the entry ‘comment_author’ stores the name: Array ( [‘comment_author’] => ‘Harriet Smith, [‘comment_author_email’] => ‘hsmith@,example.com’, [‘comment_author_url’] => ‘http://example.com/’ ) More information is available in the codex. Update To find the nice name, ask the DB: /** * Searches the user table by display name. * @param string $display_name * @return object … Read more
You can get the logged in users using wp_get_current_user(); . http://codex.wordpress.org/Function_Reference/wp_get_current_user But your probably better off just using a plugin or looking at the the following plugins code. http://wordpress.org/extend/plugins/wp-useronline/
Choosing the right template As your “User Profile”-Page is something completely custom and not the admin UI user profile page, I’d suggest to take the uthor posts page instead: get_author_link( true, get_current_user_id() ); Then modify this template. Pretty URls No need to go outside the WP template hierarchy. If you want something like ~/user, then … Read more
When a user say user A is deleted, you’re not cleaning up all traces of that user. Namely you need to go into each user following A and remove it from their user meta. This is why your function is showing blank users, because its being given stale information that’s out of date, and refers … Read more
Unless you want to retrieve custom data from the database, you will hardly ever need to make use of the WPDB class (or its global object, respectively). Though it is obviously possible to do things that way as well. Just for the sake of completeness, if you had a reason to not use a more … Read more
You can just call get_user_meta without specifying a key, and it will return all MetaValues for the user. $userdata = get_user_meta( $userID ); You may have to do a mapping for displaytitles of the Metavalue, as they are returned in an array, where the keys are the databasevalues of your metakeys. For example, you may … Read more
Yes, it does delete the usermeta. Here’s the code it uses: $meta = $wpdb->get_col( $wpdb->prepare( “SELECT umeta_id FROM $wpdb->usermeta WHERE user_id = %d”, $id ) ); foreach ( $meta as $mid ) delete_metadata_by_mid( ‘user’, $mid ); There’s identical code in wp_delete_user (for the non-multisite case) and they use the same pattern for deleting taxonomy metadata, … Read more
You can use the manage_{$screen->id}_columns hooks for this. To manage user columns we can use manage_users_columns which is passed an array of columns and whatever we don’t want we can unset(). /** * Manage User Admin Display Table Columns * * @param Array $columns * [cb] => <input type=”checkbox” /> * [username] => Username * … Read more
You probably called it too early, get_current_user_id uses wp_get_current_user, so move all your code that’s at the top level of functions.php into the init hook or appropriate equivalent. The only thing that should be in the global scope in your functions file if you want maximum compatability and efficiency is add_action and add_filter calls
