filter reusable block updates

  • Continuing from https://www.ads-software.com/support/topic/filter-before-save/

    I am trying to make changes to a reusable post’s content programmatically while saving it.

    I have tried hooking into content_save_pre and a bunch of other filters mentioned in sanitize_post_field https://developer.www.ads-software.com/reference/functions/sanitize_post_field/

    add_filter('edit_post_content', function ($content, $post_id) {
	error_log('======> edit_content');
	return $content;
}, 10, 2);

add_filter('content_edit_pre', function ($content, $post_id) {
	error_log('======> edit_content');
	return $content;
}, 10, 2);

add_filter('edit_post_content', function ($content, $post_id) {
	error_log('======> edit_post_content');
	return $content;
}, 10, 2);

add_filter('pre_post_content', function ($content) {
	error_log('======> pre_content');
	return $content;
});

add_filter('post_content_pre', function ($content) {
	error_log('======> content_pre');
	return $content;
});

add_filter('post_content', function ($content, $post_id, $context) {
	error_log('======> edit_content');
	return $content;
}, 10, 3);

add_filter('post_post_content', function ($content) {
	error_log('======> post_content');
	return $content;
});

    I see nothing in my error log.

    I wonder if I am looking at the right place. Is there a HOOK to filter saving reusable blocks at all?

    Thanks
    Shawn

    Since reusable blocks are just posts, you could try the most obvious hook:
    save_post

    using something like if ( 'wp_block' !== $post->post_type ) { you can check if you are saving a reusable block or else.

    I did not test this but that is how I would approach the issue, before testing the other hooks you mention above.

    Thanks.

    save_post is an action hook but I tried it out anyway. Doesn’t trigger. 

    add_action( 'save_post', function($post_id, $post, $update) {
	error_log('====> save_post');
	if ($post->post_type == 'wp_block') {
		$post->post_content = myfunc($post->post_content);
		wp_update_post($post);
	}
}, 10, 3);

    At this point, I might have to dig the REST API source. I doubt wp_blocks are treated as posts. Otherwise it would have triggered some HOOK by now.

    Tried out these two hooks too, no dice

    Interesting!

    (Reusable) Blocks are definitely posts, they even have their own post edit screens and get saved in the posts database table as posts of type wp_block.

    save_post would then logically be the hook to go when you want to do things when a post is saved, inclusive make changes to the saved post, even if it is an action.
    So my intuition said – use that.

    But as said, I did not try this with (reusable) blocks, so I was not 100% sure if it works.
    Was worth a try.

    Sorry I couldn’t be of better help on this one ??

    With the all-mighty all hook, I confirmed that there is absolutely no hook triggered when a reusable hook is being saved(updated).

    Oddly when I start creating a new hook by going to /wp-admin/post-new.php?post_type=wp_block a few hooks are triggered – but this is useless because the content field is still empty at this point. When I click the Save Draft or Publish button, there is no hook triggered.

    In my case, I need my code to run whenever a reusable block is saved (whether newly inserted or updated). Since it seems no hooks are triggered in neither of the cases. I had to find workarounds.

    Luckily, by trashing the block the content_save_pre, save_post_wp_block, save_post actions hooks and the pre_post_content filter hook are triggered. They also trigger when I click the “undo” link after the block has been trashed.

    It is tedious of course and I don’t know why somehow block updating falls out of the normal WP hook chain. It’s completely inconsistent and confusing. But that’s as good as I can get for now.

    @wpshushu,

    Please try this code (tested and worked for me):

    add_filter( 'content_save_pre', function ( $value ) {
	error_log('======> edit_content');
	return $value;
});

    Be aware that block editor saving happens in front-end context, so don’t wrap it in a conditional as is_admin() or add it in an admin_init hook either.
