限制每个分类的自定义帖子数量

我正在使用DevinVinson/WordPress-Plugin-Boilerplate 作为插件的基础，我已经创建了一个自定义帖子类型book 以及与之相关的分类法rack.

我需要的是把每架书的数量限制在10本以内；如果数字超过，则应将帖子另存为草稿并显示错误。。现在就输了。。需要帮助。。

这是我到目前为止所拥有的！

private function define_admin_hooks() {
    $this->loader->add_action( \'save_post\', $plugin_admin, \'save_post\' );
    $this->loader->add_action( \'admin_notices\', $plugin_admin, \'admin_notices\' );
}

我有另一个admin类，其中定义了上述函数

public function save_post( $post_id ) {
    global $post;
    if (defined(\'DOING_AUTOSAVE\') && DOING_AUTOSAVE)
        return;
    if (isset($_POST[\'post_type\']) && $_POST[\'post_type\'] == \'book\') {
        // If the book is assigned to taxonomy "rack" having more than 10 books, the admin_notices function is to be called
        return;
    }
}

public function admin_notices() {
    if ( ! isset( $_GET[\'YOUR_QUERY_VAR\'] ) ) {
        return;
    }
    ?>
    <div class="error">
        <p><?php _e( \'Max Book limit reached for the selected rack!\', \'odin-lms\' ); ?></p>
    </div>
    <?php
}

public function save_post( $post_id ) { global $post; if (defined(\'DOING_AUTOSAVE\') && DOING_AUTOSAVE) { return; } if (isset($_POST[\'post_type\']) && $_POST[\'post_type\'] == \'book\') { $max_allowed = 10; $terms = get_terms( [\'taxonomy\' => \'rack\'] ); $terms_ids = wp_list_pluck( $terms, \'term_id\' ); $args = [ \'post_type\' => \'book\', \'post_status\' => \'published\', \'tax_query\' => [ [ \'taxonomy\' => \'rack\', \'field\' => \'term_id\', \'terms\' => $terms_ids ] ], \'numberposts\' => $max_allowed + 1 // just need to retrieve one more than the allowed to know whether it passed the max ]; $posts = get_posts( $args ); if( count( $posts ) > $max_allowed ) { // Assuming this is the right method to remove actions; use the right one otherwise; // This is to prevent infinite loop $this->loader->remove_action( \'save_post\', $plugin_admin, \'save_post\' ); $post = [ \'ID\' => $post_id, \'post_status\' => \'draft\' ] // Update the post with status "draft" wp_update_post( $post ); // Re-add the action $this->loader->add_action( \'save_post\', $plugin_admin, \'save_post\' ); } }
