add_filter

Hello, I’m trying to figure out how to use ACF and add_filter. I have a function where for a page, I can add a code snippet with an ID, and it pulls in all data from that ID (code below).

Before we started with ACF, it worked by pulling in the_post with add_filter and everything got pulled across. It causes and issue with breadcrumbs though, where the breadcrumbs are related to original post. Eg:

HOME / COURSE / COURSE #1 – this is original course with data
HOME / COURSE / COURSE #7 – this has ID of course #1 in main WP editor field and pulls data across from #1.

Originally I did:

add_filter('the_post', 'ghost_blog', $priority=1);

But since it overwrote my breadcrumbs, I changed it to:

add_filter('the_content', 'ghost_blog', $priority=1);

The problem is that it doesn’t pull across all ACF data. So I was wondering if there was some ACF related filter I can hook into, to get chance to pull all info across.

Thanks!

	global $wpdb;
	global $post;
	
	$content = $post->post_content;
	
	$search = "@\[ghost=(\d+)\]@i";
	if (preg_match_all($search, $content, $matches, PREG_SET_ORDER)) 
	{
		foreach ($matches as $match) 
		{
			$ghost_id = trim($match[1]);
			$inner_query = new WP_Query("post_type=page&page_id=$ghost_id");
			if( $inner_query->have_posts() )
			{
				$inner_query->the_post();
			}
		}
	}
}
add_filter('the_post', 'ghost_blog', $priority=1);
