在 WooCommerce 中，我使用一個代碼來顯示牛排重量選擇表單，保存選擇數據并在購物車、結帳頁面、編輯訂單時和電子郵件通知中顯示這些數據。// Display Custom Checkbox Fieldadd_action('woocommerce_product_options_general_product_data', 'steak_custom_field_add');function steak_custom_field_add(){ global $post; // Checkbox woocommerce_wp_checkbox( array( 'id' => '_steak_checkbox', 'label' => __('Steak Weight', 'woocommerce' ), 'description' => __( 'If necessary, enable steak weight selection', 'woocommerce' ) ) );}// Save Custom Checkbox Fieldadd_action('woocommerce_process_product_meta', 'steak_custom_field_save');function steak_custom_field_save($post_id){ // Custom Product Checkbox Field $steak_checkbox = isset( $_POST['_steak_checkbox'] ) ? 'yes' : 'no'; update_post_meta($post_id, '_steak_checkbox', esc_attr( $steak_checkbox ));}// Display Custom Select Boxadd_action( 'woocommerce_before_add_to_cart_button', 'display_steak_custom_field', 0 );function display_steak_custom_field() { global $product; // If is single product page and have the "steak_checkbox" enabled we display the field if ( $product->get_meta( '_steak_checkbox' ) === 'yes' ) { echo '<div class="steak_select_box">'; $select = woocommerce_form_field( 'steak_custom_options', array( 'type' => 'select', 'class' => array('my-steak-select-box form-row-wide'), 'label' => __('Steak Weight'), 'required' => false, 'return' => false, 'options' => array( ) ), '' ); echo $select; echo '</div>'; }}但不幸的是，我不知道如何解決一個問題......本產品價格以每100克計算。最小起訂量為 300 克。而我需要的是，在選擇產品的重量時，應該據此計算該產品的最終成本。

要調整產品價格，在購物車頁面等。根據從下拉列表中選擇的重量，添加以下代碼
function my_before_calculate_totals( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// Loop through cart items
foreach ( $cart->get_cart() as $cart_item_key => $cart_item ) {
if( isset( $cart_item['steak_option'] ) ) {
// Remove the last 2 zeros (100g becomes 1, 300g becomes 3, 1000g becomes 10, etc...)
// Remove 'g' from grams
// convert string to integer
$chosen_weight = (int) str_replace( '00', '', str_replace('g', '', $cart_item['steak_option']) );
// Get current price
$current_price = $cart_item['data']->get_price();
// Set new price, price is already known per 100g
$cart_item['data']->set_price( $current_price * $chosen_weight );
}
}
}
add_action( 'woocommerce_before_calculate_totals', 'my_before_calculate_totals', 10, 1 );
要更改單個產品頁面上的價格，請根據下拉菜單添加此
function add_footer_steak_script() {
global $woocommerce, $product;
?>
<script type="text/javascript">
jQuery(document).ready(function ($) {
console.log('JS works!');
var price = <?php echo $product->get_price(); ?>, currency = '<?php echo get_woocommerce_currency_symbol(); ?>';
$( '[name=steak_custom_options]' ).change(function(){
if (!(this.value < 1)) {
var dropdown_val = this.value;
var remove_g = dropdown_val.replace( 'g', '' );
var remove_double_zero = remove_g.replace( '00', '' );
var product_total = parseFloat( price * remove_double_zero );
$( '.woocommerce-Price-amount' ).html( currency + product_total.toFixed(2));
}
});
});
</script>
<?php
}
add_action('wp_footer','add_footer_steak_script');
