If you don’t want him to see the admin stuff, don’t make him an admin, create an author account for him. He can use the quickpress dashboard widget to add posts from the dashboard. You can remove the other dashboard widgets so it’s the only one there. You can also use remove_menu_page() to remove any … Read more
See this very similar question. The answer can be adjusted to work with all types of files, not just images.
This may not help any, but it can’t hurt to try it… Log into your server admin area, invoke the client interface for your database administration (e.g. phpMyAdmin), delete all the posts where their ‘type’ is marked as a revision, then compact the table. If you have thousands of pages, you might also have millions … Read more

As far as I understood this right, you want to disable the possibility to reach any other side aside from the dashboard. Well, then here’s a short plugin for you: <?php ! defined( ‘ABSPATH’ ) AND exit; /* Plugin Name: (#45989) »kaiser« Allow Dashboard only access */ function wpse45989_access_dashboard_only() { if ( ! isset( get_current_screen()->id … Read more

Here is what I do to sort my custom post type by custom taxonomy in the admin. I have a custom post type called plugin_filter and a custom taxonomy assigned to it called filter_group. I add the following filter to my plugin to make the field sortable. add_filter(“manage_edit-plugin_filter_sortable_columns”, ‘plugin_filter_sort’); function plugin_filter_sort($columns) { $custom = array( … Read more
You can use function add_settings_error. More details can be found in the WordPress documentation. I have edited your previous answer to include that: function wpse_189722_limit_tag_words( $term, $taxonomy ) { if ($taxonomy === ‘post_tag’) { if ( count( preg_split( ‘/\s+/’, trim( $term ) ) ) > 2 ) { add_settings_error(‘term_too_many_words’, ‘term_too_many_words’, ‘Maximum of 2 words allowed, … Read more
