Group Custom Post Types in Relationship field output
-
Hi All,
I a trying to output the results of a relationship field. The issue I am having is I want to output the results grouped by CPT. I have searched all over and can’t quite get it to work. Below id the code I am using to group by post type, in a loop and store them in a PHP associative array.
$array = get_field('test_field'); $group = array(); foreach ( $array as $post ) { $group[$post->post_type][] = $post; }Here is the var_dump of $group…
array (size=5) 'places' => array (size=3) 0 => object(WP_Post)[12566] public 'ID' => int 728 public 'post_author' => string '1' (length=1) public 'post_date' => string '2020-01-16 03:22:25' (length=19) public 'post_date_gmt' => string '2020-01-16 03:22:25' (length=19) public 'post_content' => string '' (length=0) public 'post_title' => string 'Clarendon Bakery' (length=16) public 'post_excerpt' => string '' (length=0) public 'post_status' => string 'publish' (length=7) public 'comment_status' => string 'closed' (length=6) public 'ping_status' => string 'closed' (length=6) public 'post_password' => string '' (length=0) public 'post_name' => string 'clarendon-bakery' (length=16) public 'to_ping' => string '' (length=0) public 'pinged' => string '' (length=0) public 'post_modified' => string '2020-01-16 23:11:29' (length=19) public 'post_modified_gmt' => string '2020-01-16 23:11:29' (length=19) public 'post_content_filtered' => string '' (length=0) public 'post_parent' => int 0 public 'guid' => string 'http://localhost:10005/?post_type=places&p=728' (length=51) public 'menu_order' => int 0 public 'post_type' => string 'places' (length=6) public 'post_mime_type' => string '' (length=0) public 'comment_count' => string '0' (length=1) public 'filter' => string 'raw' (length=3) 1 => object(WP_Post)[12543] public 'ID' => int 944 public 'post_author' => string '1' (length=1) public 'post_date' => string '2020-09-16 04:31:46' (length=19) public 'post_date_gmt' => string '2020-09-16 04:31:46' (length=19) public 'post_content' => string '' (length=0) public 'post_title' => string 'Oddfellows Hall' (length=15) public 'post_excerpt' => string '' (length=0) public 'post_status' => string 'publish' (length=7) public 'comment_status' => string 'closed' (length=6) public 'ping_status' => string 'closed' (length=6) public 'post_password' => string '' (length=0) public 'post_name' => string 'oddfellows-hall' (length=15) public 'to_ping' => string '' (length=0) public 'pinged' => string '' (length=0) public 'post_modified' => string '2020-09-17 01:15:47' (length=19) public 'post_modified_gmt' => string '2020-09-17 01:15:47' (length=19) public 'post_content_filtered' => string '' (length=0) public 'post_parent' => int 0 public 'guid' => string 'http://localhost:10005/?post_type=places&p=944' (length=51) public 'menu_order' => int 0 public 'post_type' => string 'places' (length=6) public 'post_mime_type' => string '' (length=0) public 'comment_count' => string '0' (length=1) public 'filter' => string 'raw' (length=3) 2 => object(WP_Post)[12542] public 'ID' => int 943 public 'post_author' => string '1' (length=1) public 'post_date' => string '2020-09-16 04:31:32' (length=19) public 'post_date_gmt' => string '2020-09-16 04:31:32' (length=19) public 'post_content' => string '' (length=0) public 'post_title' => string 'Wesleyan Church' (length=15) public 'post_excerpt' => string '' (length=0) public 'post_status' => string 'publish' (length=7) public 'comment_status' => string 'closed' (length=6) public 'ping_status' => string 'closed' (length=6) public 'post_password' => string '' (length=0) public 'post_name' => string 'wesleyan-church' (length=15) public 'to_ping' => string '' (length=0) public 'pinged' => string '' (length=0) public 'post_modified' => string '2020-09-16 04:31:32' (length=19) public 'post_modified_gmt' => string '2020-09-16 04:31:32' (length=19) public 'post_content_filtered' => string '' (length=0) public 'post_parent' => int 0 public 'guid' => string 'http://localhost:10005/?post_type=places&p=943' (length=51) public 'menu_order' => int 0 public 'post_type' => string 'places' (length=6) public 'post_mime_type' => string '' (length=0) public 'comment_count' => string '0' (length=1) public 'filter' => string 'raw' (length=3) 'people' => array (size=1) 0 => object(WP_Post)[12541] public 'ID' => int 737 public 'post_author' => string '1' (length=1) public 'post_date' => string '2020-01-18 12:17:28' (length=19) public 'post_date_gmt' => string '2020-01-18 12:17:28' (length=19) public 'post_content' => string '<strong>Lorem Ipsum</strong> is simply dummy text of the printing and typesetting industry.

foreach ($group as $post_type => $posts) { foreach ($posts as $post) { } } -
Thanks for your reply John.
I can’t seem to get it to work. Was your code to fully replace what I had?
Here is what I am trying to format the results of the relationship field…
CPT 1
– result 1
– result 3
– result 4CPT 2
– result 2
– result 6CPT 3
– result 5etc etc..
But because the user may pick the CPT in random order the results are grouped based on the order selected in the relationship field…
CPT 1
– result 1CPT 2
– result 2CPT 1
– result 3
– result 4CPT 3
– result 5CPT 2
– result 6Hope this makes sense?

No, you asked

That is how you would loop over the group array and the nested posts in each group

You are right, thanks again John for your expertise đŸ™‚ Works perfectly
