我试图在WooCommerce手推车中覆盖一种产品的价格。问题是,我使用的是Divi,它包括ajax购物车更新。因此,当我重新加载签出页面时,我可以在1-2秒内看到覆盖的更改(在ajax加载期间),在此之后,购物车的详细信息再次被默认值覆盖。我试过每个人的想法,不同的钩子,延迟,优先级的改变,但都没有效果。
这是我的初始代码:
add_filter( 'woocommerce_calculate_totals', 'custom_cart_items_prices', 1000, 1 )
function custom_cart_items_prices( $cart_object ) {
$title = $_GET['form-title'];
$money = $_GET['money'];
if ($title && $money) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Iterating through cart items
foreach ( $cart_object->get_cart() as $cart_item ) {
// Get an instance of the WC_Product object
$wc_product = $cart_item['data'];
// Get the product name (WooCommerce versions 2.5.x to 3+)
$original_name = method_exists( $wc_product, 'get_name' ) ? $wc_product->get_name() : $wc_product->post->post_title;
// SET THE NEW NAME
$new_name = $title;
// Set the new name (WooCommerce versions 2.5.x to 3+)
if( method_exists( $wc_product, 'set_name' ) )
$wc_product->set_name( $new_name );
else
$wc_product->post->post_title = $new_name;
}
// Updated cart item price
$cart_item['data']->set_price( $money );
}}加载期间的图片(一切看起来都很棒):

当加载完成时:

Update --我也尝试了一种不同的方法,因为我使用了一个用create和Toolset插件制作的自定义表单,其中客户创建了一个具有自定义标题和价格的产品,在购物车中添加了一个默认的现有产品(并重定向到结帐页面)。我试图用提交的表格数据替换购物车的标题和价格。
这是我的代码:
// Change the product ID
add_filter('cred_commerce_add_product_to_cart', function( $product_id, $form_id, $post_id ) {
error_log($form_id);
if( $form_id == 55 ) {
if (!session_id()) {
session_start();
}
$_SESSION['target_post_id'] = $post_id;
if(isset($_POST['product-id'])){
$product_id = $_POST['product-id'];
$_SESSION['target_post_id'] = $post_id;
}
}
return $product_id;
}, 20, 3);
// change the price in cart
add_action('woocommerce_before_calculate_totals', function(){
session_start();
if($form_id != 55 && !isset($_SESSION['target_post_id']))return;
global $woocommerce;
$post_id = $_SESSION['target_post_id'];
$price = 0;
foreach ( $woocommerce->cart->get_cart() as $key => $cart_item ) {
$product_id = $cart_item['data']->get_id();
$adult_price = get_post_meta($product_id, 'wpcf-prezzo-1', true);
$adult_num = get_post_meta($post_id, 'wpcf-adult-number', true);
$child_price = get_post_meta($product_id, 'wpcf-prezzo-2', true);
$child_num = get_post_meta($post_id, 'wpcf-children-number', true);
$price = $adult_price * $adult_num + $child_price * $child_num;
$cart_item['data']->set_price($price);
}
}, 999);但也不起作用。
如何获得提交的表单数据(自定义标题和价格)并覆盖Woocommerce中的购物车标题和价格?

在使用带有自定义表单的工具集插件时,可以使用WC_Sessions存储产品ID并更改价格,请尝试以下操作:
add_filter( 'cred_commerce_add_product_to_cart', 'cred_commerce_add_product_to_cart', 20, 3 );
function cred_commerce_add_product_to_cart( $product_id, $form_id, $post_id ) {
if( $form_id == 55 && $post_id > 0 ) {
WC()->session->set( 'cp_id', $post_id );
}
return $product_id;
}
add_filter( 'woocommerce_add_cart_item_data', 'filter_add_cart_item_data', 30, 4 );
function filter_add_cart_item_data( $cart_item_data, $product_id, $variation_id ){
if ( WC()->session->get('cp_id') ) {
$cp_id = WC()->session->get('cp_id');
$product = wc_get_product($cp_id);
$cart_item_data['cp_price'] = $product->get_regular_price();
$cart_item_data['cp_title'] = $product->get_title();
}
return $cart_item_data;
}
add_action( 'woocommerce_before_calculate_totals', 'custom_cart_items_price', 30, 1 );
function custom_cart_items_price( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// Iterating through cart items
foreach ( $cart->get_cart() as $cart_item ) {
if( isset($cat_item['cp_price']) && isset($cat_item['cp_title']) ){
$cart_item['data']->set_price( $cat_item['cp_price'] );
$cart_item['data']->set_name( $cat_item['cp_title'] );
}
}
}代码在您的活动子主题(或活动主题)的function.php文件中。应该行得通。

关闭您所有的插件和瞧!你会惊讶地明白这是一个原因。
让他们一个接一个的回来,会让你知道哪一个是矛盾的。然后..。请考虑对特定于WordPress的问题使用WordPress堆栈交换。

1个woocommerce_add_cart_item_data
add_filter( 'woocommerce_add_cart_item_data', function($cart_item_data, $product_id, $variation_id ){
if ( empty( $_GET['form-title'] ) || empty( $_GET['money'] ) ) {
return;
}
$title = $_GET['form-title'];
$money = $_GET['money'];
$cart_item_data['form-title'] = $title ;
$cart_item_data['money'] = $money ;
return $cart_item_data;
} ,100,4);2个woocommerce_before_calculate_totals
add_action( 'woocommerce_before_calculate_totals', 'update_custom_price', 10, 1 );
function update_custom_price( $cart_object ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) ) {
return;
}
foreach ( $cart_object->cart_contents as $cart_item_key => $cart_item ) {
if(isset($cart_item["money"]) ){
$money = $cart_item["money"] ;
$cart_item['data']->set_price( $money);
}
if(isset($cart_item["form-title"]) ){
$title = $cart_item["form-title"] ;
}
$wc_product = $cart_item['data'];
// Get the product name (WooCommerce versions 2.5.x to 3+)
$original_name = method_exists( $wc_product, 'get_name' ) ? $wc_product->get_name() : $wc_product->post->post_title;
// SET THE NEW NAME
$new_name = $title;
// Set the new name (WooCommerce versions 2.5.x to 3+)
if( method_exists( $wc_product, 'set_name' ) )
$wc_product->set_name( $new_name );
else
$wc_product->post->post_title = $new_name;
}
}
return $cart_object ;
}希望这能帮上忙。
