This would depend on how your theme handles saving comments. For instance if it submits the form via ajax it will be expecting certain returns. The way I would hook into this would probably be through the pre_comment_approved filter. Checking the received email against any previously submitted posts then return unapproved if it fails. function … Read more
If I understand your problem then this should definitely work. <?php get_header(); $users = get_users( array( ‘who’ => ‘author’ ) );//get all the users with author role in an array foreach ( $users as $user ) { //travers the array if($user->caps[‘administrator’]==1)continue; // skip the user if user also have administrative capabilities $query = new WP_Query( … Read more
The filter uses the third parameter as an array that gets passed to get_terms(), which you’re already using to specify the taxonomy to query. Looking at the get_terms() documentation, you can see there’s a ‘number’ argument that you can pass to limit the number of terms returned. This is what you want to use. Your … Read more
Roles and capabilities are used to control access and normally you should use them. For example, capabilities edit_other_posts and edit_published_posts are needed to edit other user’s posts. It’s the same with othe types (pages -> edit_other_pages, edit_published_pages). Since, besides limiting the right to change other user’s posts, you also want them to be invisible, you … Read more
You can use one of the status transition filter hooks for this: {$new_status}_{$post_type} transition_post_status In the function assigned to the hook, you change the status to publish the previously featured post ( using e.g. $wpdb ). Both actions are performed after saving the post, so you have to change the status in posts other than … Read more
Exactly “where” may differ depending on your theme setup. However, there are some global-ish ways to do this if you want to tackle it that way. add_filter( ‘the_title’, ‘my_trim_words’ ); function my_trim_words( $title ) { // limit to ten words return wp_trim_words( $title, 10, ” ); } If you’d like to do this for a … Read more
One user account per person would definitely be easier, but I think you could kind of get this done by playing with the user sessions, which are stored as user_meta with the session_tokens key. Something along these lines maybe. add_action(‘template_redirect’, ‘check_max_num_sessions’); function check_max_num_sessions() { // Only check for logged in users if ( is_user_logged_in() ) … Read more
The problem is that the_excerpt() strips all HTML. There’s a good reason for this: what if the 49th word of a 50 word excerpt was the first word of a bulleted list? Or the second word in an <h1>? The way I would work around this is by using post thumbnails. These allow you to … Read more
The expected behavior of posts_per_page is to NOT count sticky posts. This can be resolved with ‘ignore_sticky_posts’ => 1, but then the posts don’t stick to the top of the menu. (In the trac ticket for sticky posts this issue is discussed.) There are some workarounds like this one, but they all feel a bit … Read more
