我想在其signle产品页面中显示每个产品的SKU字段。woocommerce 插件的设置在 wordpress 中没有该选项。
我已经按照此处的说明进行操作： https ://wordpress.stackexchange.com/questions/219410/how-to-show-product-sku-on-product-page/219427#219427
我尝试functions.php将此代码添加到我的文件中：
add_action( 'woocommerce_single_product_summary', 'dev_designs_show_sku', 5 );
function dev_designs_show_sku(){
global $product;
echo 'SKU: ' . $product->get_sku();
}
并且还尝试将这段代码添加到主题的单品内容文件中：
if ( 'sku' === $element ) {
woocommerce_template_single_sku();
}
文件名是owp-single-product.php：
<?php
/**
* Single product template.
*
* @package OceanWP WordPress theme
*/
if ( ! defined( 'ABSPATH' ) ) {
exit; // Exit if accessed directly.
}
// Get price conditional display state.
$ocean_woo_single_cond = get_theme_mod( 'ocean_woo_single_conditional', false );
// Conditional vars.
$show_woo_single = '';
$show_woo_single = ( is_user_logged_in() && $ocean_woo_single_cond === true );
/**
* Display Single Product template
*
*/
// Get elements.
$elements = oceanwp_woo_summary_elements_positioning();
// Loop through elements.
foreach ( $elements as $element ) {
do_action( 'ocean_before_single_product_' . $element );
// Title.
if ( 'title' === $element ) {
woocommerce_template_single_title();
}
// Sku.
if ( 'sku' === $element ) {
woocommerce_template_single_sku();
}
// Rating.
if ( 'rating' === $element ) {
woocommerce_template_single_rating();
}
// Price.
if ( 'price' === $element ) {
if ( false === $ocean_woo_single_cond || $show_woo_single ) {
woocommerce_template_single_price();
}
}
// Excerpt.
if ( 'excerpt' === $element ) {
woocommerce_template_single_excerpt();
}
// Quantity & Add to cart button.
if ( 'quantity-button' === $element ) {
if ( false === $ocean_woo_single_cond || $show_woo_single ) {
woocommerce_template_single_add_to_cart();
} else {
// Get Add to Cart button message display state.
$ocean_woo_single_msg = get_theme_mod( 'ocean_woo_single_cond_msg', 'yes' );
if ( 'yes' === $ocean_woo_single_msg ) {
// Get Add to Cart button replacement message.
$ocean_woo_single_msg_txt = get_theme_mod( 'ocean_woo_single_cond_msg_text' );
$ocean_woo_single_msg_txt = $ocean_woo_single_msg_txt ? $ocean_woo_single_msg_txt : esc_html__( 'Log in to view price and purchase', 'oceanwp' );
$woo_single_myaccunt_link = get_theme_mod( 'ocean_single_add_myaccount_link', false );
echo '<div class="owp-woo-single-cond-notice">';
if ( false === $woo_single_myaccunt_link ) {
echo '<span>'. $ocean_woo_single_msg_txt .'</span>';
} else {
echo '<a href="' . esc_url( get_permalink( wc_get_page_id( 'myaccount' ) ) ) . '">' . $ocean_woo_single_msg_txt . '</a>';
}
echo '</div>';
}
}
}
// Meta.
if ( 'meta' === $element ) {
woocommerce_template_single_meta();
}
do_action( 'ocean_after_single_product_' . $element );
}
不工作！我该怎么办？
