Hi
I have added the ACF for schema structured data (on products in woocommerce) but it does not show up in the structured data testing tool.
I have looked through the documentation and I can’t make head nor tail of it.
Any advice of what I need to get it to show up would be appreciated
You need to make your field “bidirectional”, in other words, there would be a relationship post on the product page that relates the product to all the posts where it is related using the post object field on the CPT. This would likely mean updating every post. There is an explanation of doing this here https://www.advancedcustomfields.com/resources/bidirectional-relationships/ and there are exiting plugins that will make relationship and post object fields bidirectional https://www.google.com/search?q=acf+budirections+relationship
If the prospect of updating every post does not appeal to you then you’ll need to do a reverse relationship query when showing the product. Basically, you need to do a WP_Query()
looking for any posts that have the product ID set in the field for the CPT.
In either of the above cases you’ll need to edit the WooCommerce templates or create filters to show the information on the product page. https://www.advancedcustomfields.com/resources/how-to-get-values-from-another-post/
Thanks everyone for posting their snippets, I thought I would share my compendium version of this just to bring it together as of Jan 2020 for other people looking to do something similar.
I can’t dedicate a million hours to solving everyone’s issues in the future but hopefully this will be useful.
My scenario was that I wanted to have a modal pop up on a button, load in an acf_form using a wordpress ajax request, and then submit it back via ajax before showing a success modal and letting the user return to the page.
I have used jquery-modal for the modal library. Installed via npm install jquery-modal
then enqueued the scripts/styles using normal wordpress features.
I have used this tutorial for figuring out how to do ajax requests – https://benmarshall.me/wordpress-ajax-frontend-backend/
The template that my WordPress ajax call returns is an acf_form() call:
acf_form(array(
'post_id' => 'new_post',
'post_title' => true,
'new_post' => array(
'post_type' => 'yourposttypehere',
'post_status' => 'publish'
),
'form' => true,
'submit_value' => __("Add your post-type", 'textdomain'),
));
I have a button to trigger it:
<a class="woocommerce-Button button js-addposttype-button" href="#">
<?php esc_html_e('Add post-type', 'textdomain'); ?>
</a>
And this monster of JS:
function setupAddPostTypeAJAX() {
$('.js-addposttype-button').on('click', function (e) {
e.preventDefault();
this.blur(); // Manually remove focus from clicked link.
var data = {
action: 'get_posttype_add_form',
security: myPostTypeAjax.security,
};
$.post(myPostTypeAjax.ajaxurl, data, function (response) {
// cant use jquery .wrap() here as it doesnt return the wrapped string
response = "<div class='modal'>" + response + "</div>";
var modalContent = $(response).appendTo('body');
acf.do_action('append', modalContent);
var $form = modalContent.find(".acf-form");
$form.on('submit', function (event) {
event.preventDefault();
});
modalContent.modal();
$form.find('.acf-form-submit .acf-button').on('click', function () {
args = {
form: $form,
reset: true,
success: function ($form) {
// Fix for Safari Webkit – empty file inputs kill the browser
// https://stackoverflow.com/a/49827426/586823
let $fileInputs = $('input[type="file"]:not([disabled])', $form)
$fileInputs.each(function (i, input) {
if (input.files.length > 0) {
return;
}
$(input).prop('disabled', true);
})
var formData = new FormData($form[0]);
// Re-enable empty file $fileInputs
$fileInputs.prop('disabled', false);
acf.lockForm($form);
$.ajax({
url: window.location.href,
method: 'post',
data: formData,
cache: false,
processData: false,
contentType: false
}).done(response => {
acf.unlockForm($form);
// show new modal saying posttype added
var modalSuccessMessage = '<div class="modal">Your posttype has been added.</div>';
$(modalSuccessMessage).appendTo('body').modal();
// could also fire off a wordpress ajax here to update the underlying page data
// if you are display a list of some kind of posttype and adding to it with this
});
}
}
acf.validateForm(args);
});
});
});
}
Its a combination of the various snippets that I’ve found throughout these forums so MASSIVE thanks to the people that have done the work on this before me. It would have been so many more hours of work without your helpful posts. I’m really grateful.
As I understand it, this will support file uploads in your form of you have file fields. If you do then check the official acf_form page docs as there is an extra thing you will need to do for the wp uploader.
Good luck everyone!
I figured it out.
add_action( ‘woocommerce_single_product_summary’, ‘display_custom_field’, 16 );
function display_custom_field ( ) {
global $product;
$pid= $product->get_id();
$actual_price = floatval($product->get_price());
$custom_price= floatval(get_post_meta($pid,’case_pack’,true));
$final_price = $actual_price * $custom_price;
echo ‘<b>Case Price:</b>’ . ‘ $’ .$final_price;
}
parent slug “woocommerce”
I created a new field – order number
Condition: record type – equal – order
And pasted the following code into the file functions.php
//Order number
add_action( 'woocommerce_email_before_order_table', 'alx_add_content_specific_email', 20, 4 );
function alx_add_content_specific_email( $order, $sent_to_admin, $plain_text, $email ) {
if ( $email->id == 'customer_completed_order' )
if (get_field('alx_sdek', $order->id)) {
echo '<h2 class="email-upsell-title">Информация об отправлении:</h2><p class="email-upsell-p">Номер отправления: <strong>';
the_field('alx_sdek', $order->id);
echo '</strong> отследить можно на сайте <a href="https://www.cdek.ru/track.html">СДЭК</a>.</p>';
}
}
I solved it for my needs.
I also added this acf for the orders.
And on a new order I copy the customer acf value to the order acf.
function my_new_order( $order_id ) {
$order = new WC_Order( $order_id );
if ( !$order ) return;
$customer_id = $order->get_customer_id();
if ( !$customer_id ) return;
$customer = new WC_Customer($customer_id);
if ( !$customer ) return;
$customer_number = $customer->get_meta('customernumber');
if ( !$customer_number ) return;
$order->add_meta_data('customernumber', $customer_number);
$res = $order->save_meta_data();
}
add_action( 'woocommerce_checkout_order_processed', 'my_new_order', 10, 1);
Thank you for your suggestion and pointing out how the Select2 handles search. I had just assumed Select2 was doing a text based search via JavaScript on the results. Knowing this, I went ahead an used the same code WooCommerce uses to search their shop_orders. The whole function is below:
/**
* WooCommerce Shop Order titles are not search friendly.
* Use the same thing WooCommerce does to modify search.
*
* Taken straight from WooCommerce
* woocommerce/includes/admin/list-tables/class-admin-list-table-orders.php
* LN 870
* FN search_custom_fields()
*
* @param WP_Query $wp
*
* @return void
*/
function prefix_modify_shop_order_search_select( $wp ) {
if( ! ( isset( $_REQUEST[‘action’] ) && ‘acf/fields/post_object/query’ == $_REQUEST[‘action’] ) ) { // Ensure we are in an ACF post_object query action
return;
} else if( ! ( isset( $_REQUEST[‘post_id’] ) && ‘options’ == $_REQUEST[‘post_id’] ) ) { // Ensure we’re in an option page ( Specific to my usecase )
return;
} else if( ! ( ‘shop_order’ == $wp->query_vars[‘post_type’] && ! empty( $wp->query_vars[‘s’] ) ) ) { // Ensure that the query is a shop_order query and search is not empty.
return;
}
/**

*/
$post_ids = wc_order_search( wc_clean( wp_unslash( $wp->query_vars[‘s’] ) ) ); // WPCS: input var ok, sanitization ok.
if ( ! empty( $post_ids ) ) {
// Remove “s” – we don’t want to search order name.
unset( $wp->query_vars[‘s’] );
// so we know we’re doing this.
$wp->query_vars[‘shop_order_search’] = true;
// Search by found posts.
$wp->query_vars[‘post__in’] = array_merge( $post_ids, array( 0 ) );
}
}
add_action( ‘parse_query’, ‘prefix_modify_shop_order_search_select’ );
WooCommerce already has the query_vars in place and ready to be parsed. At this point WooCommerce does the heavy lifting. Valid as of WooCommerce version 3.8.0

Thanks to a friend, i finally managed to organize my datas.
When you’re creating an array to store your values in a loop, this array doesn’t reset at each loop.
You just have to reset it after each nested loop.
And voilà! You have some custom $cart_object datas, ready to use to modify prices based on whatever you want.
Maybe there is a cleaner way to do it, but for now, it’s working as attended for WordPress 4.9.x/5.x.x and Woocommerce 3.5+.
If it could be usefull for anyone here is the corrected code
add_filter( 'woocommerce_add_cart_item_data', 'woocommunity_custom_cart_item_data', 20, 3 );
function woocommunity_custom_cart_item_data( $cart_item_data, $product_id, $variation_id ) {
//Targeting right product using function parameter
//And counting main loop to organize datas in their matrix
if(have_rows('custom_prices_grids', $product_id)):
$matrice_count = 0;
while(have_rows('custom_prices_grids', $product_id)): the_row();
//General limitation - already good to go
$var_limits = get_sub_field('custom_prices_variation_limitations');
$role_limits = get_sub_field('custom_prices_role_limitations');
//Targeting layout - really facultative here as i have a single layout
if( get_row_layout() == 'custom_prices_grid_details' ):
//Reorder each field in arrays
while(have_rows('custom_prices_quantity_steps')): the_row();
$min_qty[] = intval(get_sub_field('custom_prices_quantity_min'));
$max_qty[] = intval(get_sub_field('custom_prices_quantity_max'));
$custom_price[] = intval(get_sub_field('custom_prices_qty_new_price'));
$fixed_price_var[] = intval(get_sub_field('custom_prices_qty_fixed_value'));
$percent_price_var[] = intval(get_sub_field('custom_prices_qty_percent_value'));
$var_type[] = get_sub_field('price_type_calculation');
endwhile;
//Storing those fields in their matrice as $cart_item_datas
$cart_item_data['matrice-'.$matrice_count]['promo_type'] = $var_type;
$cart_item_data['matrice-'.$matrice_count]['min_qty'] = $min_qty;
$cart_item_data['matrice-'.$matrice_count]['max_qty'] = $max_qty;
$cart_item_data['matrice-'.$matrice_count]['new_price'] = $custom_price;
$cart_item_data['matrice-'.$matrice_count]['fixed_vars'] = $fixed_price_var;
$cart_item_data['matrice-'.$matrice_count]['percent_vars'] = $percent_price_var;
$cart_item_data['matrice-'.$matrice_count]['limits_by_var'] = $var_limits;
$cart_item_data['matrice-'.$matrice_count]['limits_by_role'] = $role_limits;
//Cleaning arrays at each loop
//Contrary to single values stored - Our arrays don't reset at each loop

Hai Elliot,
I am trying to figure out how to use ACF with WooCommerce and add a few extra productfields to WooCommerce products and show them on a webshop / checkout / invoice etc. but unfortunately I am getting nowhere with ACF.
What really should help is a practical walkthrough tutorial in which a new product-field is added to the WooCommerce products like for example a country when selling bottles of wine on a WooCommerce webshop and also made possible to search / filter on the custom field and show it on various pages like the checkout, invoice etc…
I have googled several hours but somehow I cannot find the right guidence to help me with this. And yes, I am rather new to WooCommerce but am an experienced developer.
You state :
2. Research on the WooCommerce website to find out how you can customize the single product page
3. Edit that template and use the ACF functions such as get_field / the_field to display your custom field data
I have not researched in depth what this all means and where to find these ‘customizing the single product page’ info but I simply cannot believe that a simple and easy walkthrough tutorial of ACF in combination with WooCommerce is non-existend.
Hope anybody can help… Or direct me to a helpful plugin to add custom fields to a WooCommerce product…
Hi,
The ACF number field will return an integer.
In php you’ll never have some decimal with an integer value, you have to work with float values.
Maybe you could simply try something like this
<?php
$price_html = $product->get_price(); //It will return a string
$x = get_field(‘custom-price’); //Integer
$float_price = floatval($price_html); //Float
$float_custom_price = floatval($x); //Float
$finalPrice = ($float_price + $float_custom_price); //Float
echo $finalPrice;
?>
But this will only display your custom price.
If you want to actually modify your price you have to use woocommerce filters.
In product page :
// Simple, grouped and external products
add_filter(‘woocommerce_product_get_price’, ‘custom_price’, 99, 2 );
add_filter(‘woocommerce_product_get_regular_price’, ‘custom_price’, 99, 2 );
// Variations
add_filter(‘woocommerce_product_variation_get_regular_price’, ‘custom_price’, 99, 2 );
add_filter(‘woocommerce_product_variation_get_price’, ‘custom_price’, 99, 2 );
This is what I’m using to disable core blocks, and WooCommerce blocks. The core blocks I want to use are at the bottom.
function remove_default_blocks($allowed_blocks){
// Get widget blocks and registered by plugins blocks
$registered_blocks = WP_Block_Type_Registry::get_instance()->get_all_registered();
// Disable Widgets Blocks
unset($registered_blocks['core/calendar']);
unset($registered_blocks['core/legacy-widget']);
unset($registered_blocks['core/rss']);
unset($registered_blocks['core/search']);
unset($registered_blocks['core/tag-cloud']);
unset($registered_blocks['core/latest-comments']);
unset($registered_blocks['core/archives']);
unset($registered_blocks['core/categories']);
unset($registered_blocks['core/latest-posts']);
unset($registered_blocks['core/shortcode']);
// Disable WooCommerce Blocks
unset($registered_blocks['woocommerce/handpicked-products']);
unset($registered_blocks['woocommerce/product-best-sellers']);
unset($registered_blocks['woocommerce/product-category']);
unset($registered_blocks['woocommerce/product-new']);
unset($registered_blocks['woocommerce/product-on-sale']);
unset($registered_blocks['woocommerce/product-top-rated']);
unset($registered_blocks['woocommerce/products-by-attribute']);
unset($registered_blocks['woocommerce/featured-product']);
// Now $registered_blocks contains only blocks registered by plugins, but we need keys only
$registered_blocks = array_keys($registered_blocks);
// Merge allowed core blocks with plugins blocks
return array_merge(array(
'core/image',
'core/paragraph',
'core/heading',
'core/list'
), $registered_blocks);
}
add_filter('allowed_block_types', 'remove_default_blocks');
Ok! I’ve resolved my self!
WooCommerce have a function in it’s core, callled: woocommerce_register_post_type_product
This function use the: register_post_type (default function in WP)
And in WooCommerce there is 1 params called: capability_type
This params change all default “post” or “posts” in WP, in new capabilities for WooCommerce.
Examples:
edit_post become edit_product
edit_posts becomes edit_products
Hope it help someone in the future to resolve conflicts about WP media gallery in front-end with WooCommerce products!
@exnihilo_maxime This is the whole code I am using
$GLOBALS['wc_loop_variation_id'] = null;
function is_field_group_for_variation($field_group, $variation_data, $variation_post) {
return (preg_match( '/Variation/i', $field_group['title'] ) == true);
}
add_action( 'woocommerce_product_after_variable_attributes', function( $loop_index, $variation_data, $variation_post ) {
$GLOBALS['wc_loop_variation_id'] = $variation_post->ID;
foreach ( acf_get_field_groups() as $field_group ) {
if ( is_field_group_for_variation( $field_group, $variation_data, $variation_post ) ) {
acf_render_fields( $variation_post->ID, acf_get_fields( $field_group ) );
}
}
$GLOBALS['wc_loop_variation_id'] = null;
}, 10, 3 );
add_action( 'woocommerce_save_product_variation', function( $variation_id, $loop_index ) {
if ( !isset( $_POST['acf_variation'][$variation_id] ) ) {
return;
}
$_POST['acf'] = $_POST['acf_variation'][$variation_id];
acf()->input->save_post( $variation_id );
}, 10, 2 );
add_filter( 'acf/prepare_field', function ( $field ) {
if ( !$GLOBALS['wc_loop_variation_id'] ) {
return $field;
}
$field['name'] = preg_replace( '/^acf\[/', 'acf_variation[' . $GLOBALS['wc_loop_variation_id'] . '][', $field['name'] );
return $field;
}, 10, 1);
and this is line 148
acf()->input->save_post( $variation_id );
Hi @exnihilo_maxime .
Thank you very much for your reply.

That worked perfectly. Thanks for your help. That link to woocommerce hooks is really helpful too.
I think what you need to do is find the hook where you want these things displayed, have a look here:
https://businessbloomer.com/woocommerce-visual-hook-guide-single-product-page/
I think the closest hook is woocommerce_before_add_to_cart_form.
Try this in your functions.php file:
add_action('woocommerce_before_add_to_cart_form', 'display_product_fields' );
function display_product_fields() {
$fields = get_field_objects();
if( $fields ): ?>
<ul>
<?php foreach( $fields as $field ): ?>
<li><?php echo $field['label']; ?>: <?php echo $field['value']; ?></li>
<?php endforeach; ?>
</ul>
<?php endif;
}?>
HI.
I solve a similar problem, only with tags.
I searched for a solution for almost 2 hours (I didn’t find it), I didn’t find any examples, but I managed to solve my problem myself!
If it helps:
is_main_tag – field name
product_tag_ – suffix (described at the bottom of the page https://www.advancedcustomfields.com/resources/get_field/).
$post_id = false; // current post
$post_id = 1; // post ID = 1
$post_id = “user_2”; // user ID = 2
$post_id = “category_3”; // category term ID = 3
By analogy, he suggested and tried his type (woocommerce) of taxonomy and helped!
$ value = get_field (“is_main_tag”, ‘product_tag _’. $ id);
In your case, it will most likely help:
$ value = get_field (“name_of_your_field”, ‘product_cat_’. $ id);
I hope this helps you!
Good luck colleague!
Hi! I also have a similar issue with a custom select that shows users in a given role on a WooCommerce order.
I thought I had fixed it by emptying the browser cache and hard reloading, but some people have had the issue return. I’m going to investigate today and see if I can clarify the cause.
Just thought I would add a post here so you know you’re not alone! 😉
A good friend on mine solved the issue. Here is the working code:
// Use 1 column layout for art series with one work ACF based
function vv_custom_cat_layout( $options ) {
$terms = get_terms([
'taxonomy' => 'product_cat',
'hide_empty' => true,
'meta_query' => [
'key' => 'series_one_work',
'value' => 1
]
]);
$AcfFilter = [];
foreach($terms as $term)
array_push($AcfFilter, $term->slug); // i'm never sure if is term_name or just name, sorry
if ( is_product_category( $AcfFilter ) )
$options['columns'] = 1;
return $options;
}
add_filter( 'option_generate_woocommerce_settings','vv_custom_cat_layout' );
Thanks @vverner for all your help! really appreciated.
Almost, it put me in the right direction
// Category Extra Title Description in Archives
add_action( ‘woocommerce_after_subcategory_title’, ‘custom_add_product_extratitle’, 12);
function custom_add_product_extratitle ($category) {
$cat_id = $category->term_id;
$prod_term = get_term($cat_id,’product_cat’);
$term = get_field(‘alternative_title’);
$othertitle = get_field(‘alternative_title’, ‘term_’.$prod_term->term_id);
// retrieve the existing value(s) for this meta field.
echo ‘<div class=”extratext”><h2>’.$othertitle.'</h2></div>’;
}
Try this, adds a new tab in WooCommerce single page with the function inside.
/* Call Product Authors */
function list_ffpauthors() {
$post_objects = get_field(‘author’);
if( $post_objects ):
echo ‘<ul class=”authorgrid”>’;
foreach( $post_objects as $post):
setup_postdata($post);
echo ‘<li class=”authorbox”><div class=”socialimage”>ID) .'”> ‘.get_the_post_thumbnail($post->ID, $size = ‘portrait’).’</div>ID) .'”>’. get_the_title($post->ID) .’‘;
endforeach;
echo ‘‘;
wp_reset_postdata();
endif;
}
Display the items by using WooCommerce filters to add a new tab
e.g
/* New Authors Tab */
add_filter( ‘woocommerce_product_tabs’, ‘woo_new_product_tab’ );
function woo_new_product_tab( $tabs ) {
// Adds the new tab
$tabs[‘author_tab’] = array(
‘title’ => __( ‘Authors’, ‘woocommerce’ ),
‘priority’ => 50,
‘callback’ => ‘woo_new_product_tab_content’
);
return $tabs;
}
function woo_new_product_tab_content() {
// The new tab content
echo ‘<h2>Authors</h2>’;
$authornames=list_ffpauthors();
}
<?php
function vv_custom_cat_layout( $options ) {
$terms = get_terms( array(
'taxonomy' => 'product_cat',
'hide_empty' => true,
'meta_key' => 'series_one_work',
'meta_value' => '1'
) );
$AcfFilter = array();
foreach($terms as $term){
array_push($AcfFilter, $term->name); # i'm never sure if is term_name or just name, sorry
}
if ( is_product_category( $AcfFilter ) )$options['columns'] = 1;
return $options;
}
add_filter( 'option_generate_woocommerce_settings','vv_custom_cat_layout' );
