自定义价格字段未保存在 WooCommerce 中的管理产品中

Question

我向 WooCommerce 添加了一个自定义价格字段。该字段按预期出现，但它不保存输入的值。

我functions.php文件中的代码是：

/* Add custom price field to general page */

function wc_cost_product_field() {

    woocommerce_wp_text_input( array( 'id' => 'wholesaler_price', 'class' => 'wc_input_price short', 'label' => __( 'Wholesaler price', 'woocommerce' ) . ' (' . get_woocommerce_currency_symbol() . ')' ) );

}

add_action( 'woocommerce_product_options_pricing', 'wc_cost_product_field' );

function pcc_save_custom_price( $post_id ) {

    // Grab the custom price from $_POST

    $custom_price = isset( $_POST[ 'wholesale_price' ] ) ? sanitize_text_field( $_POST[ 'wholesale_price' ] ) : '';

    // grab the product

    $product = wc_get_product( $post_id );

    // Save the custom price using WooCommerce built-in functions

    $product->update_meta_data( 'wholesale_price', $custom_price );

    $product->save();

}

add_action( 'woocommerce_process_product_meta', 'pcc_save_custom_price' );

你有一些小错误，这应该足够了另请注意使用woocommerce_admin_process_product_objectto save 而不是过时的woocommerce_process_product_meta钩子/* Add custom price field to general page */function action_woocommerce_product_options_pricing() {     woocommerce_wp_text_input( array(        'id' => 'wholesaler_price',         'class' => 'wc_input_price short',         'label' => __( 'Wholesaler price', 'woocommerce' ) . ' (' . get_woocommerce_currency_symbol() . ')',    ) );}add_action( 'woocommerce_product_options_pricing', 'action_woocommerce_product_options_pricing', 10, 0 );// Save Fieldsfunction action_woocommerce_admin_process_product_object( $product ) {    if( isset($_POST['wholesaler_price']) ) {        $product->update_meta_data( 'wholesaler_price', sanitize_text_field( $_POST[ 'wholesaler_price'] ) );    }}add_action( 'woocommerce_admin_process_product_object', 'action_woocommerce_admin_process_product_object', 10, 1 );
