Make price mandatory for variations

[L Stewart]

Hi,

I would like to make price mndatory for variations. I found this code you have shared. But is this correct?

function wcfm_restrict_publish_product_variation_pricing( $variation_fileds, $variations, $variation_shipping_option_array, $variation_tax_classes_options, $products_array ) {
	global $wp;
	$product_id = 0;

	if( isset( $variation_fileds['regular_price'] ) ) {
		$variation_fileds['regular_price']['custom_attributes'] = array( 'required' => 1 );
	}
	return $variation_fileds;
}

add_filter( 'wcfm_product_manage_fields_variations', 'wcfm_restrict_publish_product_variation_pricing', 50, 5 );

In particular I don’t know what this section is for:
add_filter( 'wcfm_product_manage_fields_variations', 'wcfm_restrict_publish_product_variation_pricing', 50, 5 );

Hi,
This is how a filter is called. You can read more about this here- https://developer.wordpress.org/reference/functions/add_filter/
Argument 1: wcfm_product_manage_fields_variations is the filter name
Argument 2: ‘wcfm_restrict_publish_product_variation_pricing’ is the callback function
Argument 3 (Optional): Is the priority of this callback function. Low value of priority ensures early execution. Default value- 10
Argument 4 (Optional): Number of arguments getting passed to the callback function
Hope this helps!
Thank You!
