Woocommerce中特定产品的动态销售价格显示

Question

I need to develop a script in function file that display sale price for specific categories for registered users. This code work fine.

I need to add sale price design to it

function thenga_customer_specific_pricing( $price, $product ) {    
    if ( ! is_user_logged_in() ) {
        return $price;
    }

    $id = $product->get_id();

    if( has_term( 'daniel-wellington', 'product_cat' ,$id ) ){
        // Give these customers a 20% discount.
        return $price * 0.8;
    } elseif( has_term( 'giardino-segreto', 'product_cat' ,$id ) ){
        return $price * 0.85;
    } else {
        return $price;
    }
}
add_filter( 'woocommerce_product_get_price', 'thenga_customer_specific_pricing', 10, 2 );

I expect an output like this:

Was: 100€ Now: 80€

I tried this filter :

function custom_dynamic_sale_price_html( $price_html, $product ) {
    if( $product->is_type('variable') ) return $price_html;

    $price_html = wc_format_sale_price( wc_get_price_to_display( $product, array( 'price' => $product->get_regular_price() ) ), wc_get_price_to_display(  $product, array( 'price' => $product->get_sale_price() ) ) ) . $product->get_price_suffix();

    return $price_html;
}
add_filter( 'woocommerce_get_price_html', 'custom_dynamic_sale_price_html', 20, 2 );

but It work in all products, how I can call this filter only in specific categories?

The following code will display your expected output (for simple products):

// Discount prices
add_filter( 'woocommerce_product_get_price', 'specific_discounted_product_prices', 10, 2 );
function specific_discounted_product_prices( $price, $product ) {
    // For logged in customers
    if ( is_user_logged_in() ) {
        if( has_term( 'daniel-wellington', 'product_cat' ,$product->get_id() ) ){
            $price *= 0.8; // 20% discount
        } elseif( has_term( 'giardino-segreto', 'product_cat' ,$product->get_id() ) ){
            $price *= 0.85; // 15% discount
        }
    }
    return $price;
}

// Display the discount
add_filter( 'woocommerce_get_price_html', 'specific_discounted_product_prices_display', 10, 2 );
function specific_discounted_product_prices_display( $price, $product ) {
    // For simple products and logged in customers
    if( $product->is_type('simple') && is_user_logged_in() ){
        $regular_price = wc_get_price_to_display( $product, array( 'price' => $product->get_regular_price() ) );
        $sale_price    = wc_get_price_to_display( $product, array( 'price' => $product->get_sale_price() ) );
        $active_price  = wc_get_price_to_display( $product );

        if( $regular_price != $active_price ) {
            if( $product->is_on_sale() )
                $price = sprintf( 'Was: %s – Now: %s', wc_price($sale_price), wc_price($active_price) );
            else
                $price = sprintf( 'Was: %s – Now: %s', wc_price($regular_price), wc_price($active_price) );
        }
    }
    return $price;
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.

In case you came here to make it work with variations, you need all the following filters:

add_filter( 'woocommerce_product_get_price', 'specific_discounted_product_prices', 10, 2 );
add_filter( 'woocommerce_product_variation_get_price', 'specific_discounted_product_prices', 10, 2 );
add_filter( 'woocommerce_product_get_sale_price', 'specific_discounted_product_prices', 10, 2 );
add_filter( 'woocommerce_product_variation_get_sale_price', 'specific_discounted_product_prices', 10, 2 );
add_filter( 'woocommerce_variation_prices_price', 'specific_discounted_product_prices', 10, 2 );
add_filter( 'woocommerce_variation_prices_sale_price', 'specific_discounted_product_prices', 10, 2 );

And you need to make sure you've changed the woocommerce_get_variation_prices_hash becasue of the stored transients.

You may skip the woocommerce_get_price_html if you use the woocommerce_product_get_sale_price filter as well.

You may find the gist I've created for a client useful
