Add filter on the relationship field inside a group
-
Hello everyone,
I am trying to add a filter for the relationship field located within a group.The group has the name: link_scope_pages
The relationship field inside the group: itemsI tried the following ways but none worked:
add_filter('acf/fields/relationship/query/name=link_scope_pages_items', 'my_function', 10, 3);add_filter('acf/fields/relationship/query/name=link_scope_pages_$_items', 'my_function', 10, 3);add_filter('acf/fields/relationship/query/name=link_scope_pages_%_items', 'my_function', 10, 3);How can I access the relationship field within the group?
I paste the function I call (my_function) that I tested.
function my_function( $args, $field, $post_id ) { $args = [ 'post_type' => 'page', 'meta_query' => [ [ 'key' => '_wp_page_template', 'value' => 'tpl-scope.php', ] ] ]; return $args; }Thanks for support

Hi yes I solved it using the field key within the group.
But I wanted to know how it works via name if it is possible.

To be honest, I don’t know exactly without testing. I do know that the field name is not what you would expect when calls fires the hook. It does have to do with the hierarchy of the field. I would expect your first example to work, but, it the group field also a sub field of some other field? Is it part of a cloned fields?
The only way to find out is to create a filter for all fields and output it to see what the name is.
// all fields filter add_filter('acf/prepare_field', 'output_field_object'); function output_field_object($field) { echo '<pre>'; print_r($field); echo '</pre>'; return $field; }There have been times when I needed to use the field name and I have had to create my filter for all fields and then use ‘strpos()` to test the field name or even the field key to see if it is the field I need to filter. There is always some logic to it as to why the name is what it is for the filter.
But for the most part, whenever I am dealing with filtering a sub field of any kind I just use the field key.

Hi,
with the filter you provided me the answer is this below.The group is simple and is not contained in other groups or a clone.
Array ( [ID] => 0 [key] => field_5f1b04a650dbe [label] => [name] => acf[field_5f1b04a650dbe] [prefix] => acf [type] => group [value] => Array ( [field_5fad6bdaa2903] => 1 [field_5f1b0571deda4] => ) [menu_order] => 0 [instructions] => [required] => 0 [id] => acf-field_5f1b04a650dbe [class] => [conditional_logic] => 0 [parent] => group_5f1b04a64d28d [wrapper] => Array ( [width] => [class] => [id] => ) [layout] => block [_name] => link_scope_pages [_valid] => 1 [sub_fields] => Array ( [0] => Array ( [ID] => 0 [key] => field_5fad6bdaa2903 [label] => Automatico [name] => is_automatic [prefix] => acf [type] => true_false [value] => [menu_order] => 0 [instructions] => [required] => 0 [id] => [class] => [conditional_logic] => 0 [parent] => field_5f1b04a650dbe [wrapper] => Array ( [width] => [class] => [id] => ) [message] => [default_value] => 1 [ui] => 1 [ui_on_text] => [ui_off_text] => [wpml_cf_preferences] => 0 [_name] => is_automatic [_valid] => 1 ) [1] => Array ( [ID] => 0 [key] => field_5f1b0571deda4 [label] => Seleziona pagine ambito [name] => items [prefix] => acf [type] => relationship [value] => [menu_order] => 1 [instructions] => [required] => 1 [id] => [class] => [conditional_logic] => Array ( [0] => Array ( [0] => Array ( [field] => field_5fad6bdaa2903 [operator] => != [value] => 1 ) ) ) [parent] => field_5f1b04a650dbe [wrapper] => Array ( [width] => [class] => [id] => ) [post_type] => Array ( [0] => page ) [taxonomy] => [filters] => Array ( [0] => search ) [elements] => Array ( [0] => featured_image ) [min] => [max] => [return_format] => object [wpml_cf_preferences] => 0 [_name] => items [_valid] => 1 ) ) [_prepare] => 1 ) -
I don’t know why the group field has that name in this case.
What happens if you change add filter to
add_filter('acf/prepare_field', 'output_field_object', 1); -
what name should it have?

This is my filter that works
function filter_relationship_acf_scope_pages( $args, $field, $post_id ) { $args = [ 'post_type' => 'page', 'meta_query' => [ [ 'key' => '_wp_page_template', 'value' => 'tpl-scope.php', ] ] ]; return $args; } add_filter('acf/fields/relationship/query/key=field_5f1b0571deda4', 'filter_relationship_acf_scope_pages', 10, 3); -
I’m not sure what is causing your issue. I just set up a test field group containing a group field with a relationship field as a sub field. The name of the relationship field is simply “relationship”. I then added an acf/fields/relationship/query/name=relationship and this filter runs as expected.

Hi, my filter works if I put the name of the relationship field.
My problem is that I have many group fields with relationship fields inside all with the name “items” so the filter applies to all these fields.
I want to apply the filter only to the group field with the name “link_scope_pages” and in particular to its relation subfield with the name “items”.
From various topics such as wp_query I tried to use the group name “_” name of the subfield relationship “link_scope_pages_items” but this doesn’t work.
Here is my problem.At the moment I solved it with the key name of the relationship subfield (it seems to be unique), but I wanted to know if there was a solution with the names or even putting conditions inside the filter.
