我使用在产品编辑页面上显示自定义字段的代码.此文本框在单个产品页面上显示烹饪时间.
这是代码:
// Backend: Display additional product fields
add_action( 'woocommerce_product_options_general_product_data', 'add_time_field_general_product_data' );
function add_time_field_general_product_data() {
// Custom Time Field
woocommerce_wp_text_input( array(
'id' => '_custom_time',
'label' => __( 'Time for cooking', 'woocommerce' ),
));
}
// Backend: Save the data value from the custom fields
add_action( 'woocommerce_admin_process_product_object', 'save_time_custom_fields_values' );
function save_time_custom_fields_values( $product ) {
// Save Custom Time Field
if( isset( $_POST['_custom_time'] ) ) {
$product->update_meta_data( '_custom_time', sanitize_text_field( $_POST['_custom_time'] ) );
}
}
// Display custom fields values under item name in checkout
add_filter( 'woocommerce_checkout_cart_item_quantity', 'custom_time_field_checkout_item_name', 10, 3 );
function custom_time_field_checkout_item_name( $item_qty, $cart_item, $cart_item_key ) {
if( $value4 = $cart_item['data']->get_meta('_custom_time') ) {
$item_qty .= '<br /><div class="my-custom-style"><strong>' . __("Time for cooking", "woocommerce") . ':</strong> ' . $value4 . ' min.</div>';
}
return $item_qty;
}
// Display custom fields values on orders and email notifications
add_filter( 'woocommerce_order_item_name', 'custom_time_field_order_item_name', 10, 2 );
function custom_time_field_order_item_name( $item_name, $item ) {
$product = $item->get_product();
if( $value4 = $product->get_meta('_custom_time') ) {
$item_name .= '<br /><span class="my-custom-style"><strong>' . __("Time for cooking", "woocommerce") . ':</strong> ' . $value4 . ' min.</span>';
}
return $item_name;
}
如何根据此代码获得以下功能?
例如,客户向购物车和结帐订单添加了几道菜.他看到有多少时间在煮这道菜.
但是,当客户选择按快递方式(统一费率)交货时,在同一块中显示交货时间.
固定费率= $10
交货时间=(从订单中选择最长的烹饪时间)分钟. 45分钟
据我了解,下订单时需要获取自定义字段“ _custom_time”的数据.然后,以某种方式需要获得该字段的最大值并增加45分钟.
我寻求您的帮助!我希望这个问题的答案对许多开发人员有用.
解决方法:
尝试以下代码,当在结帐页面上选择“统一费率”运输方式时,该代码将显示交付时间(根据最高商品烹饪时间值45分钟计算):
add_action( 'woocommerce_after_shipping_rate', 'action_after_shipping_rate_callback', 10, 2 );
function action_after_shipping_rate_callback( $method, $index ) {
$chosen_shipping_id = WC()->session->get( 'chosen_shipping_methods' )[$index];
if( is_checkout() && $method->method_id === 'flat_rate' && $method->id === $chosen_shipping_id ) {
$extra_time = 45; // Additional time to be added
$data_array = []; // Initializing
// Loop through car items
foreach ( WC()->cart->get_cart() as $cart_item ) {
if( $cooking_time = $cart_item['data']->get_meta('_custom_time') ) {
$data_array[] = (int) $cooking_time;
}
}
if ( sizeof($data_array) ) {
$max_time = (int) max($data_array);
$delivery_time = $max_time + $extra_time;
echo '<br><small style="margin-left:2em;border:solid 1px #ccc;padding:2px 5px;"><strong>' . __("Delivery time", "woocommerce") . '</strong>: ' . $delivery_time . ' min.</small>';
}
}
}
代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试和工作.
To enable that in cart page too, remove
is_checkout() &&
from theIF
statement.
