Envirodefence,
It looks like you need to do a meta_query in your get_posts() function. You can find the docs here: https://www.advancedcustomfields.com/resources/query-posts-custom-fields/. Look under the Custom Fields advanced section for an example on how to query a checkbox. Essentially, you will add a query field like so:
'meta_query' => array(
'key' => 'featured_type',
'value' => 'about',
'compare' => '=',
),
),
Jez,
If I am understanding you correctly, you have a Custom Field in CPT b and you want CPT a to have access to the options that are selected?
To target a specific field in a CPT you would change this block
$args = array(
'public' => true
);
$post_types = get_post_types($args);
foreach ($post_types as $post_type) {
if ($post_type !== 'attachment' && $post_type !== 'page')
$field['choices'][$post_type] = ucfirst($post_type);
}
to something like
$cpt_custom_field = get_field($cpt_id, 'the_name_of_the_specific_field');
foreach ($cpt_custom_field['choices'] as $value=>$label) {
$field['choices'][ $value ] = [ $label ];
}
Or whatever you want to replace the information with. Nested repeater fields are slightly more complicated, but code examples for that are in the docs. You could create a colors array and assign the select to those, you can grab all post names from a CPT and assign those, etc. You just need to change the above code to match what you are loading into the choices field.
Yes, I am actually doing this with a dropdown, but it is the same concept. The Documentation can be found here: https://www.advancedcustomfields.com/resources/acf-load_field/.
You can use something like add_filter('acf/load_field/name=cpt_all', 'acf_load_post_types'); to limit the use to any custom fields named cpt_all. Here is the code that I am using:
function acf_load_post_types( $field ) {
// reset choices
$field['choices'] = array();
$args = array(
'public' => true
);
$post_types = get_post_types($args);
foreach ($post_types as $post_type) {
if ($post_type !== 'attachment' && $post_type !== 'page')
$field['choices'][$post_type] = ucfirst($post_type);
}
// return the field
return $field;
}
add_filter('acf/load_field/name=cpt_all', 'acf_load_post_types');
