根据wp_post_insert，过滤器wp_insert_post_empty_content应该适合您。

   /**
     * Filters whether the post should be considered "empty".
     *
     * The post is considered "empty" if both:
     * 1. The post type supports the title,editor,and excerpt fields
     * 2. The title,and excerpt fields are all empty
     *
     * Returning a truthy value to the filter will effectively short-circuit
     * the new post being inserted,returning 0. If $wp_error is true,a WP_Error
     * will be returned instead.
     *
     * @since 3.3.0
     *
     * @param bool  $maybe_empty Whether the post should be considered "empty".
     * @param array $postarr     Array of post data.
     */
    if ( apply_filters( 'wp_insert_post_empty_content',$maybe_empty,$postarr ) ) {
        if ( $wp_error ) {
            return new WP_Error( 'empty_content',__( 'Content,title,and excerpt are empty.' ) );
        } else {
            return 0;
        }
    }

您可以在wp_insert_post_empty_content过滤器中进行条件查询，并返回true以阻止帖子被插入。

感谢您的投入，我认为@KGreene的答案值得一试。

我已经改变了策略，如果用户没有jeton，我将重定向用户，这样他们甚至都看不到编辑器，然后在其他钩子上发布时烧掉jeton。

/*
*   Redirect user that doesnt have jeton,let others proceed
*   https://developer.wordpress.org/reference/hooks/save_post/
*/
function handle_before_publish_post($post_id,$post,$update) {

     // Only on post creation not update (they can update with 0 jeton)
    if ($update) {
        return;
    }

    $poster_id = $post->post_author;
    $meta_jeton = get_user_meta($poster_id,'jeton')[0];

    if ($meta_jeton > 0) {
        return;
    } else {
        wp_redirect('[my-domain]/wp-admin/edit.php?post_type=[my-custom-post-type]');
    }
}
add_action('save_post_[my-custom-post-type]','handle_before_publish_post',10,3);

/*
*   Use a jeton on post creation
*   https://developer.wordpress.org/reference/hooks/new_status_post-post_type/
*/
function handle_after_publish_post($post_id,$post) {

    // Burn jeton
    $poster_id = $post->post_author;
    $meta_jeton = get_user_meta($poster_id,'jeton')[0];
    $new_jeton_count = $meta_jeton - 1;

    update_user_meta($poster_id,'jeton',$new_jeton_count);
    return;
}
add_action('publish_[my-custom-post-type]','handle_after_publish_post',3);

这不是我想要的方式，但是效果很好。

谢谢大家的时间
