問題描述
限時送ChatGPT賬號..
在 woocommerce 中，我在添加到購物車按鈕之前添加了一個額外的文本字段，以在產品購買時添加自定義費用.
此插件會為單個產品頁面添加額外的文本字段并計算總計加上額外費用.
我的問題是我無法添加自定義購物車總數，并且在總數之前添加額外費用
我嘗試了 woocommerce_cart_calculate_fees 但不幸的是它只顯示 $0 的總數

解決方案
您不需要任何 javascript 或會話來實現這一點.請嘗試使用以下重新訪問的代碼:
//單次加入購物車前添加自定義字段add_action('woocommerce_before_add_to_cart_button', 'custom_product_price_field', 5);函數 custom_product_price_field(){echo '<p>額外費用('.get_woocommerce_currency_symbol().'):</p><input type="text" name="custom_price" value="" placeholder="e.g. 10" title="Custom Text" class="custom_price text_custom text">
';}//獲取自定義字段值，計算新商品價格，保存為自定義購物車商品數據add_filter('woocommerce_add_cart_item_data', 'add_custom_field_data', 20, 2 );函數 add_custom_field_data( $cart_item_data, $product_id ){if (!isset($_POST['custom_price']))返回 $cart_item_data;$custom_price = (float) sanitize_text_field( $_POST['custom_price'] );如果(空($custom_price))返回 $cart_item_data;$product = wc_get_product($product_id);//WC_Product 對象$base_price = (float) $product->get_regular_price();//產品注冊價格//新的價格計算$new_price = $base_price + $custom_price;//在購物車對象中設置自定義數量$cart_item_data['custom_data']['extra_charge'] = (float) $custom_price;$cart_item_data['custom_data']['new_price'] = (float) $new_price;$cart_item_data['custom_data']['unique_key'] = md5( microtime() . rand() );//使每個項目都是唯一的返回 $cart_item_data;}//設置新計算的購物車商品價格add_action('woocommerce_before_calculate_totals', 'extra_price_add_custom_price', 20, 1 );功能 extra_price_add_custom_price( $cart ) {if ( is_admin() && !defined( 'DOING_AJAX' ) )返回;if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )返回;foreach ( $cart->get_cart() as $cart_item ) {if( isset($cart_item['custom_data']['new_price']) )$cart_item['data']->set_price( (float) $cart_item['custom_data']['new_price'] );}}//顯示購物車項目自定義價格詳細信息add_filter('woocommerce_cart_item_price', 'display_cart_items_custom_price_details', 20, 3);功能 display_cart_items_custom_price_details( $product_price, $cart_item, $cart_item_key ){if( isset($cart_item['custom_data']['extra_charge']) ) {$product = $cart_item['data'];$product_price = wc_price( wc_get_price_to_display( $product, array( 'price' => $product->get_regular_price() ) );$product_price .= '
'.wc_price( $cart_item['custom_data']['extra_charge'] ).' ';$product_price .= __("額外收費", "woocommerce");}返回 $product_price;}
代碼位于活動子主題(或活動主題)的 function.php 文件中.經測試有效.
In woocommerce I have added an extra text field before add to cart button to add custom charge on product purchase.
This plugin will add extra text field to single product page and calculates total plus the extra charge.
My problem is that I cant add custom cart totals and the extra charge add before totals
I tried woocommerce_cart_calculate_fees but no luck it only show $0 in totals

解決方案
You don't need any javascript or sessions to achieve that. Try the following revisited code instead:
// Add a custom field before single add to cart
add_action( 'woocommerce_before_add_to_cart_button', 'custom_product_price_field', 5 );
function custom_product_price_field(){
echo '<div class="custom-text text">
<p>Extra Charge ('.get_woocommerce_currency_symbol().'):</p>
<input type="text" name="custom_price" value="" placeholder="e.g. 10" title="Custom Text" class="custom_price text_custom text">
</div>';
}
// Get custom field value, calculate new item price, save it as custom cart item data
add_filter('woocommerce_add_cart_item_data', 'add_custom_field_data', 20, 2 );
function add_custom_field_data( $cart_item_data, $product_id ){
if (! isset($_POST['custom_price']))
return $cart_item_data;
$custom_price = (float) sanitize_text_field( $_POST['custom_price'] );
if( empty($custom_price) )
return $cart_item_data;
$product = wc_get_product($product_id); // The WC_Product Object
$base_price = (float) $product->get_regular_price(); // Product reg price
// New price calculation
$new_price = $base_price + $custom_price;
// Set the custom amount in cart object
$cart_item_data['custom_data']['extra_charge'] = (float) $custom_price;
$cart_item_data['custom_data']['new_price'] = (float) $new_price;
$cart_item_data['custom_data']['unique_key'] = md5( microtime() . rand() ); // Make each item unique
return $cart_item_data;
}
// Set the new calculated cart item price
add_action( 'woocommerce_before_calculate_totals', 'extra_price_add_custom_price', 20, 1 );
function extra_price_add_custom_price( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
foreach ( $cart->get_cart() as $cart_item ) {
if( isset($cart_item['custom_data']['new_price']) )
$cart_item['data']->set_price( (float) $cart_item['custom_data']['new_price'] );
}
}
// Display cart item custom price details
add_filter('woocommerce_cart_item_price', 'display_cart_items_custom_price_details', 20, 3 );
function display_cart_items_custom_price_details( $product_price, $cart_item, $cart_item_key ){
if( isset($cart_item['custom_data']['extra_charge']) ) {
$product = $cart_item['data'];
$product_price = wc_price( wc_get_price_to_display( $product, array( 'price' => $product->get_regular_price() ) ) );
$product_price .= '<br>' . wc_price( $cart_item['custom_data']['extra_charge'] ).' ';
$product_price .= __("Extra Charge", "woocommerce" );
}
return $product_price;
}
Code goes in function.php file of your active child theme (or active theme). Tested and works.
