Show log on front end using block or shortcode

[bonny]

Over the years mulitple people have requested this feature so perhaps it's something to consider.

Related support threads:

• https://wordpress.org/support/topic/shortcode-for-displaying-the-feed-on-a-page/
• https://wordpress.org/support/topic/shortcodes-to-display-data/

• https://wordpress.org/support/topic/display-log-on-front-end/
• https://wordpress.org/support/topic/simple-history-front-end-ui/

Things to consider and challenges:

• Who can add the shortcode/block?
• How to control what is showed, so sensitive/personal information is not revealed at frontend

Hello, I can provide my code for this

    $message = $row->message;

    // Check if post still is available.
    // It will return a WP_Post Object if post still is in system.
    // If post is deleted from trash (not just moved there), then null is returned.
    $post = get_post( $post_id );

    $post_is_available = is_a( $post, 'WP_Post' );

Hello,

do we have filter "simple_history/log_query_inner_where" ?
I think it is not working now.

Thank you.

Ah, no you are correct, it probably went missing after a big rewrite to support full group by #409

I'll add another issue about this and see if I can bring it back.

Thank you for your great work!!

@1ucay the next version will have a new filter to replace the filter that went missing. See here for more info: #455
