我已在产品页面的常规设置选项卡上的WooCommerce Admin中创建了自定义字段,以便为制造插入一些天 . 我想在每个产品名称上方的购物车和结帐页面上显示此自定义字段值 .
这是我的代码:
// Insert a Custom Admin Field
function woo_add_custom_general_fields() {
echo '<div class="options_group">';
woocommerce_wp_text_input( array(
'id' => 'days_manufacture',
'label' => __( 'Days for Manufacture', 'woocommerce' ),
'placeholder' => '',
'description' => __( 'Insert here', 'woocommerce' ),
'type' => 'number',
'custom_attributes' =>
array(
'step' => 'any',
'min' => '1'
)
) );
echo '</div>';
}
add_action( 'woocommerce_product_options_general_product_data', 'woo_add_custom_general_fields' );
// Save field
function woo_add_custom_general_fields_save( $post_id ){
$woocommerce_number_field = $_POST['days_manufacture'];
if( !empty( $woocommerce_number_field ) )
update_post_meta( $post_id, 'days_manufacture', esc_attr( $woocommerce_number_field ) );
}
add_action( 'woocommerce_process_product_meta', 'woo_add_custom_general_fields_save' );
function save_days_field( $cart_item_data, $product_id ) {
if( isset( $_REQUEST['days_manufacture'] ) ) {
$cart_item_data[ 'days_manufacture' ] = get_post_meta( $post->ID, 'days_manufacture',true );
/* below statement make sure every add to cart action as unique line item */
$cart_item_data['unique_key'] = md5( microtime().rand() );
}
return $cart_item_data;
}
add_action( 'woocommerce_add_cart_item_data', 'save_days_field', 10, 2 );
function render_meta_on_cart_and_checkout( $cart_data, $cart_item = null ) {
$custom_items = array();
/* Woo 2.4.2 updates */
if( !empty( $cart_data ) ) {
$custom_items = $cart_data;
}
if( isset( $cart_item['days_manufacture'] ) ) {
$custom_items[] = array( "name" => 'Days:', "value" => $cart_item['days_manufacture'] );
}
return $custom_items;
}
add_filter( 'woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2 );
但这不起作用,因为我无法在购物车和结帐页面上显示自定义字段值 .
我怎样才能做到这一点?
谢谢

我已经测试了您的代码并更正了一些部分,以使该产品自定义字段显示在购物车和结帐页面上 .
这是更正后的代码:
当然,这可以在您的活动子主题(或主题)的function.php文件中,也可以在任何插件文件中 .
This code is tested and works.
