CPT ACF Fields not working with ID parameter

  • I’m trying to pull ACF fields from related posts for a custom post type named Locations I’ve created. The fields appear without problem within the post itself when an ID is not specified.

    I’ve tried retrieving the field directly with an ID in the single-locations.php file inside and outside the content loop with no luck.

    This code snippet below (for testing purposes) is currently inside of an ACF block template file that is added to the post type.

    	global $post;
    	$id = get_the_ID();
    	the_field('display_address'); //this works
    	echo $id; // returns the custom post ID
    	the_field('display_address', $id); //this does not.

    post dump:
    object(WP_Post)#1254 (24) { [“ID”]=> int(1109) [“post_author”]=> string(1) “1” [“post_date”]=> string(19) “2019-11-15 18:53:46” [“post_date_gmt”]=> string(19) “2019-11-15 18:53:46” [“post_content”]=> string(2470) “ ” [“post_title”]=> string(8) “East Bay” [“post_excerpt”]=> string(0) “” [“post_status”]=> string(7) “publish” [“comment_status”]=> string(6) “closed” [“ping_status”]=> string(6) “closed” [“post_password”]=> string(0) “” [“post_name”]=> string(8) “east-bay” [“to_ping”]=> string(0) “” [“pinged”]=> string(0) “” [“post_modified”]=> string(19) “2019-11-16 19:22:16” [“post_modified_gmt”]=> string(19) “2019-11-16 19:22:16” [“post_content_filtered”]=> string(0) “” [“post_parent”]=> int(0) [“guid”]=> string(54) “http://localhost:8888/?post_type=locations&p=1109” [“menu_order”]=> int(0) [“post_type”]=> string(9) “locations” [“post_mime_type”]=> string(0) “” [“comment_count”]=> string(1) “0” [“filter”]=> string(3) “raw” }

    I saw somewhere in my internet searching that CPT have their name prepended to the ID. I’ve tried several syntactically different ways of combining the two with no luck, also.

    Any insight on this would be much appreciated because I have no idea why this wouldn’t be working.

    Thank you,

  • After some digging through the ACF API files, I tested the acf_get_valid_post_id function. When no ID is passed into the function, the ID that gets returned looks something like block_[RANDOM STRING]. When an ID is passed into the function, the ID that was passed in just gets returned.

    When I use that block string as the ID parameter, everything actually works as expected. My current predicament now is retrieving those block string keys dynamically through the wordpress post ID because currently, I can only get those keys when no post ID is provided (So it only works on the specific post page itself).
