可变产品的价格（woocommerce）

Question

Tell me please. Where does the basket get the value of the variational product, with the subsequent multiplication by the number and the issuance of the TOTAL and the SUBTOTAL ? The problem is that you need to send the cost of the products from an custom field to the basket.

For a simple product, everything turned out. The following function was added to the file abstract-wc-product.php :

public function get_rrp_price( $context = 'view' ) {
    return $this->get_meta( $key = 'rrp_price', $context = 'view' );
}

Where rrp_price - is the name of an arbitrary field with a new price. Then in the template class-wc-cart.php , namely in the following functions:

public function calculate_totals(
public function get_product_subtotal(

I am replaced $product->get_price() with $product->get_rrp_price() and for a simple product it all worked!

But when you add a variable product, the basket issues ZERO . I can not understand in what place it can be fixed, I guess that in class-wc-product-variable.php , but if so, where and how?

Answer 1

I have faced this problem before but i found the solution please check below code i think from that you can get perfect idea.

function opal_varient_price( $price, $variation ) {

if (  $variation->product_type == 'variation'  ) {

    $user = $user ? new WP_User( $user ) : wp_get_current_user();
    $role = $user->roles[0];
    if($role == 'detailer'){$pricex = get_post_meta( $variation->variation_id, 'dist',true);}
    else if($role == 'reseller'){$pricex = get_post_meta( $variation->variation_id, 'res',true);}  
    else{ $pricex = $price;}
    }
return $pricex;
}

add_filter( 'woocommerce_product_variation_get_regular_price', 'opal_varient_price' , 99, 2 );
add_filter( 'woocommerce_product_variation_get_sale_price', 'opal_varient_price' , 99, 2 );
add_filter( 'woocommerce_product_variation_get_price', 'opal_varient_price', 99, 2 );

Answer 2

I've tried to this (changed 'dist' and 'rest' for 'rrp_price' ):

function opal_varient_price( $price, $variation ) {

if (  $variation->product_type == 'variation'  ) {

    $user = $user ? new WP_User( $user ) : wp_get_current_user();
    $role = $user->roles[0];
    if($role == 'detailer'){$pricex = get_post_meta( $variation->variation_id, 'rrp_price',true);}
    else if($role == 'reseller'){$pricex = get_post_meta( $variation->variation_id, 'rrp_price',true);}  
    else{ $pricex = $price;}
    }
return $pricex;
}

add_filter( 'woocommerce_product_variation_get_regular_price', 'opal_varient_price' , 99, 2 );
add_filter( 'woocommerce_product_variation_get_sale_price', 'opal_varient_price' , 99, 2 );
add_filter( 'woocommerce_product_variation_get_price', 'opal_varient_price', 99, 2 );

But variable products still ZERO in a cart.
