我正在定制WooCommerce,我想在产品页面中添加和显示自定义文本(条件和品牌)。
该头寸位于“库存”或“SKU”元下。我已设法创建并保存自定义字段,但如何将这些元值打印到产品页面。
请帮忙!
以下是 functions.php
:
// Display Fields
add_action( 'woocommerce_product_options_general_product_data', 'woo_add_custom_general_fields' );
// Text Field
function woo_add_custom_general_fields() {
global $woocommerce, $post;
echo '<div class="options_group">';
woocommerce_wp_text_input(
array(
'id' => '_conditions',
'label' => __( 'Conditions', 'woocommerce' ),
'placeholder' => 'i.e: brand-new; refurbished; defected...',
'desc_tip' => 'true',
'description' => __( 'Enter the conditions of the products here.', 'woocommerce' )
)
);
echo '</div>';
woocommerce_wp_text_input(
array(
'id' => '_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' )
)
);
}
// Save Fields
add_action( 'woocommerce_process_product_meta', 'woo_add_custom_general_fields_save' );

您的问题中提供的代码不完整,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,要在产品页面中显示此元数据值,您将在钩子函数中使用get_post_meta()
函数。在下面,您将看到 woocommerce_single_product_summary
挂钩中所有挂钩的模板及其优先级(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
*/
“库存”或“SKU”数据由 woocommerce_template_single_meta
显示,优先级为40.现在您需要在之后显示关税字段值。然后,您可以为此选择 45 的优先级。
以下是在“SKU”下的产品页面中输出自定义字段值的代码:
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>';
}
代码进入活动子主题(活动主题或任何插件文件)的function.php文件中。
此代码经过测试并有效。
