php - Conditionally alter specific product price in Woocommerce

问题描述

I would like to alter a specific product in Woocommerce, adding programmatically to its original an amount of $10, EXCEPT in those cases:

I was using this answer code to one of my questions until now. But I should need to display this specific product altered price everywhere except on that product pages that are bookable products, in front end.

I have also this code that displays the Force Sells price beside the titles. This should still show the specific product original price on that product pages that are bookable products in the Force Sells section:

function wc_forcesells_product_price( $name, $product ) {
    // Only in single product pages
    if( ! is_product() ) return $name;

    // The product name + the product formatted price
    return $name . ' (' . wc_price( wc_get_price_to_display( $product ) ) . ')';
}
add_filter( 'woocommerce_product_title', 'wc_forcesells_product_price', 20, 2 );

Reference for above: Add price beside Woocommerce Force Sells.

解决方案

如有必要，更新以处理多个产品 ID

尝试以下操作，将为特定产品 ID 显示自定义价格，除了：

  • 关于预订产品以租用页面
  • 当产品类别在购物车中时

该代码还将更改购物车项目中的此自定义产品价格，除非特定产品类别位于购物车项目中。

您必须在这些功能中进行设置：

  • 此特定产品 ID
  • 要租用的预订产品 ID
  • 附加价格金额
  • 产品类别（Id slug 或名称）

编码：

// Change product ID 87 price everywhere on front end EXCEPT:
// - On booking products to hire pages
// - When a product category is in cart
add_filter( 'woocommerce_get_price_html', 'product_id_87_displayed_price', 10, 2 );
function product_id_87_displayed_price( $price_html, $product ) {
    // Only for product ID 87
    if( in_array( $product->get_id(), array( 87, 2799 ) ) ){ 
        return $price_html; // Exit

    // HERE set booking products IDs to hire in the array
    $product_ids_to_hire = array( 53, 738 );

    // HERE set your product category term ID, slug or name
    $product_category = 'hoodies';

    // HERE set the price additional amount
    $addp = 10;

    // EXCEPT on booking products to hire pages
    if( is_single($product_ids_to_hire) ) return $price_html; // Exit

    // Checking for the product category in cart items loop
    foreach ( WC()->cart->get_cart() as $cart_item ) {
        if ( has_term( $product_category, 'product_cat', $cart_item['product_id'] ) )
             return $price_html; // Product category found ==> Exit
    }

    if ( '' !== $product->get_price() && ! $product->is_on_sale() ) {
        $price_html = wc_price( wc_get_price_to_display( $product ) + $addp ) . $product->get_price_suffix();
    }
    return $price_html;
}

// Add custom calculated price to cart item data for product ID 87
add_filter( 'woocommerce_add_cart_item_data', 'add_cart_simple_product_custom_price', 20, 2 );
function add_cart_simple_product_custom_price( $cart_item_data, $product_id ){
    // Only for product ID 87
    if( ! in_array( $product->get_id(), array( 87 ) ) ) 
        return $cart_item_data; // Exit

    // HERE set the price additional amount
    $addp = 10;

    $product = wc_get_product($product_id); // The WC_Product Object
    $price   = (float) $product->get_price(); // The product price

    // Set the custom amount in cart object
    $cart_item_data['new_price'] = $price + $addp;

    return $cart_item_data;
}

// Set custom calculated price to cart for product ID 87
add_action( 'woocommerce_before_calculate_totals', 'set_cart_simple_product_custom_price', 20, 1 );
function set_cart_simple_product_custom_price( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
        return;

    // HERE set your product category term ID, slug or name
    $product_category = 'hoodies';

    // 1st cart items Loop: checking for the product category
    foreach ( $cart->get_cart() as $cart_item ) {
        if ( has_term( $product_category, 'product_cat', $cart_item['product_id'] ) )
            return; // Product category found ==> We EXIT from this function
    }

    // 2nd Loop: Changing cart item prices (Product category not found)
    foreach ( $cart->get_cart() as $cart_item ) {
        if( isset($cart_item['new_price']))
            $cart_item['data']->set_price( $cart_item['new_price'] );
    }
}

代码位于您的活动子主题（或活动主题）的 function.php 文件中。测试和工作。

它也应该适用于您的wc_forcesells_product_price()功能。
