How to create a bidirectional custom field?

[tislars]

In the current version of ACF Pro you are able to create a custom field with a bidirectional relationship. Is this possible with acf-composer? I do not see any related information in this repository or the cheatsheet.

I'm pretty sure all config options will be passed through to ACF, so it should 'just work' :) give it a try! + PR's always welcome if improvements needed in the docs

This should help from the ACF Builder repo - StoutLogic/acf-builder#121 (comment)

Currently, the Bidirectional setting is only available for the Relationship, User, Taxonomy, and Post Object fields

Thanks for the quick response, looks promising. However, on my end it does not work. Here is my code:

<?php
...
class ProductLocation extends Field
{
    /**
     * The field group.
     */
    public function fields(): array
    {
        $productLocation = Builder::make('product_location');

        $productLocation
            ->setLocation('post_type', '==', 'product-location')
            ->addRelationship('location_product_groups', [
                'post_type'              => 'product-group',
                'instructions'           => '',
                'acfe_bidirectional' => [
                    'acfe_bidirectional_enabled' => true,
                    'acfe_bidirectional_related'   => [
                        'field_group_product_locations',
                    ],
                ],
                'filters' => [
                    0 => 'search',
                ],
            ]);


        return $productLocation->build();
    }
}

<?php
...
class ProductGroup extends Field
{
    /**
     * The field group.
     */
    public function fields(): array
    {
        $productGroup = Builder::make('product_group');

        $productGroup
            ->setLocation('post_type', '==', 'product-group')
            ->addRelationship('group_product_locations', [
                'post_type'              => 'product-location',
                'instructions'           => '',
                'acfe_bidirectional' => [
                    'acfe_bidirectional_enabled' => true,
                    'acfe_bidirectional_related'   => [
                        'field_location_product_groups',
                    ],
                ],
                'filters' => [
                    0 => 'search',
                ],
            ]);

        return $productGroup->build();
    }
}

As you can see I use the value in the array key acfe_bidirectional_related with the name I set in the other fields instance. I also tried the name of what the page source tells me in the dashboard. Over there the name is field_product_location_location_product_groups and field_product_group_group_product_locations. But when I try this it also does not work.

Did you ever manage to figure this out? Can you try the latest version of ACF Composer?

[tislars]

Sorry for the late response. I missed your reply.

Sadly, I did not figure out what is going wrong. To this day I still have some projects where we'd like to apply bi-directional fields, but it's not working. I am running the latest version of ACF Composer.

@tislars
'acfe_bidirectional' is using ACF Extended, which is no longer needed for bidirectional relationship since it's already included in ACF natively. Try with this:

$productGroup
            ->setLocation('post_type', '==', 'product-group')
            ->addRelationship('group_product_locations', [
                'post_type'              => 'product-location',
                'instructions'           => '',
               'bidirectional' => true,
                    'bidirectional_target' => [
                      0 => 'related_field_name_here'
                    ],
                'filters' => [
                    0 => 'search',
                ],
            ]);
