如何为某些帖子创建有效的内容过滤器?

In addition, in my WordPress theme's functions.php, I have the following:

# ==============================================================================================
# [Filter]
#
# Every hour, using WP_Cron, `my_updated_posts` is checked. If there are new Post IDs in there,
# it will run a filter on all of the post's content. The filter will search for Glossary terms
# and scientific species names. If found, it will replace those names with links including a 
# pop-up.

    include "filter.php";

# ==============================================================================================
# When saving a post (new or edited), check to make sure it isn't a revision then add its ID
# to `my_updated_posts`.

    add_action( 'save_post', 'my_set_content_filter' );
    function my_set_content_filter( $post_id ) {
        if ( !wp_is_post_revision( $post_id ) ) {

            $post_type = get_post_type( $post_id );

            if ( $post_type == "species" || ( $post_type == "post" && in_category( "articles", $post_id ) ) || ( $post_type == "post" && in_category( "blogs", $post_id ) ) ) {
                //get the previous value
                $ids = get_option( 'my_updated_posts' );

                //add new value if necessary
                if( !in_array( $post_id, $ids ) ) {
                    $ids[] = $post_id;
                    update_option( 'my_updated_posts', $ids );
                }
            }
        }
    }

# ==============================================================================================
# Add the filter to WP_Cron.

    add_action( 'my_filter_posts_content', 'my_filter_content' );
    if( !wp_next_scheduled( 'my_filter_posts_content' ) ) {
        wp_schedule_event( time(), 'hourly', 'my_filter_posts_content' );
    }

# ==============================================================================================
# Run the filter.

    function my_filter_content() {
        //check to see if posts need to be parsed
        if ( !get_option( 'my_updated_posts' ) )
            return false;

        //parse posts
        $ids = get_option( 'my_updated_posts' );

        update_option( 'error_check', $ids );

        foreach( $ids as $v ) {
            if ( get_post_status( $v ) == 'publish' )
                run_filter( $v );

            update_option( 'error_check', "filter has run at least once" );
        }

        //make sure no values have been added while loop was running
        $id_recheck = get_option( 'my_updated_posts' );
        my_close_out_filter( $ids, $id_recheck );

        //once all options, including any added during the running of what could be a long cronjob are done, remove the value and close out
        delete_option( 'my_updated_posts' );
        update_option( 'error_check', 'working m8' );
        return true;
    }

# ==============================================================================================
# A "difference" function to make sure no new posts have been added to `my_updated_posts` whilst
# the potentially time-consuming filter was running.

    function my_close_out_filter( $beginning_array, $end_array ) {
        $diff = array_diff( $beginning_array, $end_array );
        if( !empty ( $diff ) ) {
            foreach( $diff as $v ) {
                run_filter( $v );
            }
        }
        my_close_out_filter( $end_array, get_option( 'my_updated_posts' ) );
    }

正如(希望)代码注释所描述的那样，这种工作方式是 WordPress 每小时运行一个 cron 作业(这就像一个虚假的 cron - 对用户点击起作用，但这并不重要，因为时间不重要)运行上面找到的过滤器.
