ACF Field Group Values

This component provides a convenient alternative to ACF's get_field() function. It can be installed as a WordPress plugin, or required as a dependency (preferred) within your theme or plugin.

Requirements

• PHP 7.3+

Installation

The recommended way to install this component is with Composer:

composer require timothyjensen/acf-field-group-values

Alternatively, you can download the latest release and install it like a typical WordPress plugin.

Usage

As of version 2.0.0 the $config argument must contain all data from the acf field group export. This is a breaking change. Also, you should now pass $config instead of $config['fields']. This is especially important when working with clone fields.

1. Configure ACF to save field group JSON files within your theme or plugin. Next, convert the ACF field group JSON to an array that will be passed to the helper function get_all_custom_field_meta():

   <?php
   
   // Replace with the name of your field group JSON.
   $field_group_json = 'group_59e226a200966.json';
   
   $config = json_decode( file_get_contents( PATH_TO_ACF_JSON . $field_group_json ), true );

2. Build an array containing all post meta for the specified field group:

   <?php
   
   $acf_post_meta = get_all_custom_field_meta( get_the_ID(), $config );

3. Build an array containing all option values for the specified field group:

   <?php
   
   $acf_option_values = get_all_custom_field_meta( 'option', $config );

4. Build an array containing all term meta for the specified field group:

   <?php
   
   $term_id = 'term_2';
   
   $acf_term_values = get_all_custom_field_meta( $term_id, $config );

5. Build an array containing all user meta for the specified field group:

   <?php
   
   $user_id = 'user_2';
   
   $acf_user_values = get_all_custom_field_meta( $user_id, $config );

6. Build a multidimensional array containing all ACF block data for the specified field group:

   <?php
   // The $block variable is passed to the render callback or template.
   $data = $block['data'];
   
   $acf_block_data = get_structured_block_data( $data, $config );

7. In order to retrieve values for clone fields you must pass a third argument: all field group arrays that contain the fields that will be cloned.

   <?php
   
   // Replace with the names of your field group JSONs.
   $clone_json_1 = 'group_59e226a200967.json';
   $clone_json_2 = 'group_59e226a200968.json';
   
   $clone_fields = [
   	json_decode( file_get_contents( PATH_TO_ACF_JSON . $clone_json_1 ), true ),
   	json_decode( file_get_contents( PATH_TO_ACF_JSON . $clone_json_2 ), true )
   ];
   
   $acf_post_meta = get_all_custom_field_meta( get_the_ID(), $config, $clone_fields );

8. As of version 3.2 you can include field labels along with values in the results.

   <?php
   
   // Passing 'true' as the fourth argument will include field labels in the results.
   $acf_post_meta = get_all_custom_field_meta( get_the_ID(), $config, [], true );
   
   /* The above results in:
   'group' => [
       'group_1'  => [
           'label' => 'Group 1 Label',
           'value' => 'Group 1',
       ],
       'group_2'  => [
           'label' => 'Group 2 Label',
           'value' => 'Group 2',
       ],
       'subgroup' => [
           'subgroup1' => [
               'label' => 'Subgroup 1 Label',
               'value' => 'Subgroup 1',
           ],
           'subgroup2' => [
               'label' => 'Subgroup 2 Label',
               'value' => 'Subgroup 2',
           ],
       ],
   ]
   */

Example Results

In the test results below get_all_custom_field_meta() was 600% faster than get_field() and required 19 fewer database queries. Note that the returned values are raw meta values as opposed to formatted values that can be returned by get_field().

<?php

$results = [
    'group'            => [
        'group_1'  => 'Group 1',
        'group_2'  => 'Group 2',
        'subgroup' => [
            'subgroup1' => 'Subgroup 1',
            'subgroup2' => 'Subgroup 2',
        ],
    ],
    'repeater'         => [
        [
            'repeater_sub_field' => 'Sub Field',
            'repeater_2'         => [
                [
                    'repeater_2_subfield' => 'Level 2 subfield',
                ],
                [
                    'repeater_2_subfield' => 'Level 2 subfield',
                ],
            ],
        ],
    ],
    'flexible_content' => [
        [
            'acf_fc_layout'      => 'flex_content_type_1',
            'flex_content_field' => 'Flex content type 1',
        ],
        [
            'acf_fc_layout'      => 'flex_content_type_2',
            'flex_content_field' => 'Flex content type 2',
        ],
    ],
    // The following are cloned fields.
    'group_1'          => 'Cloned group 1',
    'subgroup'         => [
        'subgroup1' => 'Cloned subgroup 1',
        'subgroup2' => 'Cloned subgroup 2',
    ],
];
