I have created custom taxonomy "Brands" and attached to woocommerce products. Unfortunately, It is not available in woocommerce REST API response.
How to attach custom taxonomy term to woocommerce rest API. Currently there is no documentation about attachment of custom taxonomy. Is there any hook or filter ?
I solved by using this code.You will be able to GET and Update custom taxonomy by using this method. Basically. You can add this code in functions.php file or in plugin.
Step:1
Replace brands with your taxonomy_name.
Step:2
If your taxonomy have custom fields, replace custom_field_name with yours.
Taxonomy Code:
add_action( 'init', 'create_brands_hierarchical_taxonomy', 0 );
//create a custom taxonomy name it topics for your posts
function create_brands_hierarchical_taxonomy() {
// Add new taxonomy, make it hierarchical like categories
//first do the translations part for GUI
$labels = array(
'name' => _x( 'Brands', 'taxonomy general name' ),
'singular_name' => _x( 'Brand', 'taxonomy singular name' ),
'search_items' => __( 'Search Brands' ),
'all_items' => __( 'All Brands' ),
'parent_item' => __( 'Parent Brand' ),
'parent_item_colon' => __( 'Parent Brand:' ),
'edit_item' => __( 'Edit Brand' ),
'update_item' => __( 'Update Brand' ),
'add_new_item' => __( 'Add New Brand' ),
'new_item_name' => __( 'New Brand Name' ),
'menu_name' => __( 'Brands' ),
);
$capabilities = array(
'manage_terms' => 'manage_woocommerce',
'edit_terms' => 'manage_woocommerce',
'delete_terms' => 'manage_woocommerce',
'assign_terms' => 'manage_woocommerce',
);
// Now register the taxonomy
$args = array(
'labels' => $labels,
'show_in_rest' => true,
'hierarchical' => true,
'public' => true,
'show_ui' => true,
'show_admin_column' => false,
'show_in_nav_menus' => true,
'show_tagcloud' => true,
'capabilities' => $capabilities,
);
register_taxonomy( 'brands', array( 'product' ), $args );
register_taxonomy_for_object_type( 'brands', 'product' );
}
Register Taxonomy API for WC
//Register taxonomy API for WC
add_action( 'rest_api_init', 'register_rest_field_for_custom_taxonomy_brands' );
function register_rest_field_for_custom_taxonomy_brands() {
register_rest_field('product', "brands", array(
'get_callback' => 'product_get_callback',
'update_callback' => 'product_update_callback',
'schema' => null,
));
}
//Get Taxonomy record in wc REST API
function product_get_callback($post, $attr, $request, $object_type)
{
$terms = array();
// Get terms
foreach (wp_get_post_terms( $post[ 'id' ],'brands') as $term) {
$terms[] = array(
'id' => $term->term_id,
'name' => $term->name,
'slug' => $term->slug,
'custom_field_name' => get_term_meta($term->term_id, 'custom_field_name', true)
);
}
return $terms;
}
//Update Taxonomy record in wc REST API
function product_update_callback($values, $post, $attr, $request, $object_type)
{
// Post ID
$postId = $post->get_id();
//Example: $values = [2,4,3];
// Set terms
wp_set_object_terms( $postId, $values , 'brands');
}
Solution above is working but you have to change the
$postId = $post->get_id();
with
$postId = $post->ID;
Took me ages to find out why update_callback did not work : $values contains the taxonomy-structure and is therefore too complex to pass as integer to wp_set_object_terms. You have to strip it to the numeric ID's only otherwise [null] is assigned
//Update Taxonomy record in wc REST API
function product_update_callback_Leerjaar($values, $post, $attr, $request, $object_type)
{
// Post ID
$postId = $post->id;
//Example: $values = [2,4,3];
error_log("debug on values");
error_log(json_encode($values));
$numarray = [];
foreach($values as $value){
$numarray[] = (int)$value['id'];
}
wp_set_object_terms( $postId, $numarray , 'brands');
}
If anyone has tested all the above and can't get it to work, I found a simplest and working solution, based on Taha Farooqui's answer and the wordpress register_rest_field documentation :
add_action( 'rest_api_init', 'register_rest_field_for_custom_taxonomy_brands');
function register_rest_field_for_custom_taxonomy_brands() {
register_rest_field('product', "field_rest_name",
array("get_callback" => function ($post) {
$taxonomy = wp_get_post_terms( $post['id'], 'your_taxonomy_name');
return $taxonomy;
}
)
);
}
After months of testing trying to prove why the product_update_callback() function returned a null value, he got a version that loads the taxonomy values from the woocommerce Rest Api v3 only with the name and slug..

function create_brands_hierarchical_taxonomy() {
// Add new taxonomy, make it hierarchical like categories
$labels = array(
'name' => _x( 'Marcas', 'taxonomy general name' ),

));
}
//Get Taxonomy record in wc REST API
function product_get_callback_brand($post, $attr, $request, $object_type){
$terms = array();
// Get terms
foreach (wp_get_post_terms( $post[ 'id' ],'pwb-brand') as $term) {
$terms[] = array(
'id' => $term->term_id,
'name' => $term->name,
'slug' => $term->slug,
);
}
return $terms;
}
//Update Taxonomy record in wc REST API
function product_update_callback_brand($values, $post, $attr, $request, $object_type){
// Post ID
$postId = $post->id;
$terms = $values;
$termName = $terms[0]['name'];
$termSlug = $terms[0]['slug'];
wp_insert_term( $termName, 'pwb-brand', array( 'slug' => $termSlug ) );
error_log("debug on values");
error_log(json_encode($values));
$newTermId = get_term_by('slug',$termSlug,'pwb-brand')->term_id;
array_push($values, array('id' => (int)$newTermId));
$numarray = [];
foreach($values as $value){
if(is_numeric($value['id'])){
$numarray[] = (int)$value['id'];
}
}
wp_set_object_terms( $postId, $numarray , 'pwb-brand');
}
After so much testing he understood that the values that pass through the product_get_callback_brand function are mandatory to register a taxonomy so if you add a custom field like in the first example then they must be loaded so that the taxonomy can be retrieved.
It is worth noting that it is not a valid field for image fields or galleries that will not have the permissions to be loaded by the Rest Api v3 of woocommerce
What is the customizer section name? I want to add a field option under customizer woocommerce section. Or how will I add a field under woocommerce option? Can someone help me with that?
$wp_customize->add_section( 'woocommerce_secction_name' , array(
'title' => __( 'My Section Name', 'starter' ),
'priority' => 30
) );
$wp_customize->add_setting( 'starter_new_setting_name' , array(
'default' => '#000000',
'transport' => 'refresh',
) );
$wp_customize->add_control( new WP_Customize_Color_Control( $wp_customize, 'link_color', array(
'label' => __( 'Header Color', 'starter' ),
'section' => 'woocommerce_secction_name',
'settings' => 'starter_new_setting_name',
) ) );
// Add section to WooCommerce Panel
$wp_customize->add_section( 'SECTION_NAME',
array(
'title' => __( 'SECTION TITLE'),
'panel' => 'woocommerce',
'capability' => '',
'priority' => 500,
)
);
The important part is the panel name as you can see selecting woocommerce it will add to the woocomerce panel
I use CMB2 — WordPress Plugins to create Custom Metaboxes. I have a textarea for embeding video. I need to validate the field in right way both on input and output.

I am writing a plugin in which I have below custom post type:
function create_post_type_contact() {
register_post_type('contact',
array(
'labels' => array(
'name' => __( 'Contacts'),
'singular_name' => __( 'contact'),
'add_new' => __('Add New contact' ),
'add_new_item' => __('Add New contact' ),
'edit_item' => 'Edit Contact',
'new_item' => 'New Contact',
'view_item' => 'View Contact',
'search_items' => 'Search Contact',
'not_found' => 'No contacts found',
'not_found_in_trash' => 'No contacts found in Trash'
),
'public' => true,
'menu_position' => 24,
'menu_icon' => 'dashicons-email',
'rewrite' => array(
'slug' => __('contact')
),
'supports' => array( 'title'),
));
}
Also have added below custom meta fields:
// Field Array
$custom_meta_fields_contact = array(
array(
'label'=> __('Contact Name'),
'desc' => 'Enter Contact Name here',
'id' => 'contact_name',
'type' => 'text'
),
array(
'label'=> __('Contact Address'),
'desc' => 'Enter Contact address here',
'id' => 'contact_address',
'type' => 'textarea'
),
array(
'label'=> __('Contact No'),
'desc' => 'Enter Contact number here',
'id' => 'contact_no',
'type' => 'text'
),
array(
'label'=> __('Contact Email'),
'desc' => 'enter contact email id here',
'id' => 'contact_email',
'type' => 'text'
),
);
I have added functions to show custom meta fields and save custom meta, which is OK and working.
Within this plugin I need to call contact_email meta field. For which I have added following code :
// get the Contact email address
$args_contact = array('post_type' => 'contact');
$contact_posts = new WP_Query($args_contact);
if($contact_posts->have_posts()) :
while($contact_posts->have_posts()) : $contact_posts->the_post();
$to = get_post_meta($post->ID, 'contact_email');
endwhile; endif;
wp_reset_query();
But whenever I am trying to get the value of $to inside the plugin , its returning nothing. Where as in the contact page am able to get and display contact_name, contact_number, contact_address and contact_email properly.
Any help or suggestion will be appreciated.
Use this
get_post_meta(get_the_ID(), 'contact_email', true);
OR declare global $post variable after if condition
if($contact_posts->have_posts()) :
global $post;
