You may want to display custom ACF fields on the vendor dashboard and make these available to each vendor for their own products.
Here is how we can achieve this:
Step 1) Adding the necessary scripts and functions
Add the following PHP code snippet to your site - for example you can add this to functions.php:
add_action('marketking_extend_page', function($pageid){
?>
<div id="marketking_footer_hidden">
<?php
wp_footer();
?>
</div>
<?php
});
add_filter('marketking_css_queue', function($q){
$new_items = array('acf-global','acf-input','acf-pro-input','acf-datepicker','acf-timepicker','tinymce','tinymce-root');
$q = array_merge($q, $new_items);
return $q;
}, 10, 1);
add_filter('marketking_js_queue', function($q){
$new_items = array('acf-global','acf-input','acf-pro-input','acf-datepicker','acf-timepicker','acf-color-picker-alpha','tinymce','tinymce-root');
$q = array_merge($q, $new_items);
return $q;
}, 10, 1);
add_action('marketking_after_save_product', function($product_id, $vendor_id){
do_action( 'acf/save_post', $product_id );
}, 10, 2);
2) Display your custom field on the vendor product page
Let's create a text field in ACF. For testing, we created this simple 'productcolor' field:

Then to display this field on the vendor dashboard page, we add this PHP code snippet:
add_action( 'marketking_edit_product_after_tags', function($post){
acf_form_head();
?>
<div class="col-xxl-12 col-md-12 marketking_card_gal_cat_tags" style="background: white; padding:20px;border-radius: 4px;">
<?php
$product_id = $post->ID;
acf_form(array(
'fields' => array('productcolor'),
'form' => false,
'post_id' => $product_id,
));
?>
</div>
<?php
});
(it's important to replace 'productcolor' with the name of your custom field)
That's it!
We now have an editable field on the edit-product page:
