I have used the following function to set an initial stock custom field, works great. But I would like it only be set when a specific product_cat is met.

Working function:

//create initial stock from _Stock.
add_action('cred_save_data','func_initial_stock',10,2);
function func_initial_stock($post_id,$form_data) {

if ($form_data['id']==9999) {
$stock = get_post_meta($post_id, '_stock', true);
update_post_meta($post_id, 'wpcf-initial-stock', $stock);
}
}

I wanted to add "if product_cat" to the function. Not working:

//create initial stock from _Stock.
add_action('cred_save_data','func_initial_stock',10,2);
function func_initial_stock($post_id,$form_data) {

if ($form_data['id']==9999) {
if ($form_data['product_cat']== 'specific_cat_slug') {
$stock = get_post_meta($post_id, '_stock', true);
update_post_meta($post_id, 'wpcf-initial-stock', $stock);
}
}
}

Any thoughts?
Thank you.

Hi, since a taxonomy field supports multiple terms, the conditional syntax is array-based and a bit more complex. It's simpler to use the built-in WordPress function has_term to test whether the post has a specific term from a specific taxonomy:

if ( has_term( 'specific-term-slug', 'product_cat', $post_id ) ) {
  $stock = get_post_meta($post_id, '_stock', true);
  update_post_meta($post_id, 'wpcf-initial-stock', $stock);
}

Let me know if you have questions about this implementation.
