在你的问题中提供的代码是不完整的,应该是这样的:
// Enabling and Displaying Fields in backend
add_action('woocommerce_product_options_general_product_data', 'woo_add_custom_general_fields');
function woo_add_custom_general_fields() {
global $woocommerce, $post;
echo '<div class="options_group">';
woocommerce_wp_text_input(array(// Text Field type
'id' => '_conditions',
'label' => __('Conditions', 'woocommerce'),
'placeholder' => 'i.e: brand-new; refurbished; defected...',
'desc_tip' => 'true',
'description' => __('Enter the conditions of the products here.', 'woocommerce')
));
woocommerce_wp_text_input(array(// Text Field type
'id' => '_brands', // ===> NOT '_bands'
'label' => __('Brands', 'woocommerce'),
'placeholder' => 'i.e: Lacoste; Hugo Boss...etc',
'desc_tip' => 'true',
'description' => __('Enter names of the Brands of the products if any.', 'woocommerce')
));
echo '</div>'; // Closing </div> tag HERE
}
// Save Fields values to database when submitted (Backend)
add_action('woocommerce_process_product_meta', 'woo_save_custom_general_fields');
function woo_save_custom_general_fields($post_id){
// Saving "Conditions" field key/value
$conditions_field = $_POST['_conditions'];
if(!empty($conditions_field))
update_post_meta($post_id, '_conditions', esc_attr($conditions_field));
// Saving "Brands" field key/value
$brands_field = $_POST['_brands'];
if(!empty($brands_field))
update_post_meta($post_id, '_brands', esc_attr($brands_field));
}
现在,在您的产品页面中显示此元数据值时,您将使用get_post_meta()
函数进行挂钩函数上。这里下面你将看到woocommerce_single_product_summary
钩所有的钩状模板及其优先级(显示顺序):
/**
* woocommerce_single_product_summary hook
*
* @hooked woocommerce_template_single_title - 5
* @hooked woocommerce_template_single_price - 10
* @hooked woocommerce_template_single_excerpt - 20
* @hooked woocommerce_template_single_add_to_cart - 30
* @hooked woocommerce_template_single_meta - 40
* @hooked woocommerce_template_single_sharing - 50
*/
的“库存”或“SKU”数据由woocommerce_template_single_meta
其中拥有优先显示现在你需要显示你的关卡字段值。然后,您可以为此选择优先级。
这是在“SKU”要输出的自定义字段中的值在产品页面代码:
add_action('woocommerce_single_product_summary', 'woo_display_custom_general_fields_values', 45);
function woo_display_custom_general_fields_values() {
global $product;
echo '<p class="custom-conditions">Conditions: ' . get_post_meta($product->id, '_conditions', true) . '</p>';
echo '<p class="custom-brands">Brands: ' . get_post_meta($product->id, '_brands', true) . '</p>';
}
代码放在您的活动子主题的function.php文件(活动主题或任何插件文件)。
此代码已经过测试并可正常工作。
