WooCommerce：从产品变体中获取自定义字段并将其显示为变体价格的后缀

Question

我试图从产品变体的自定义数字字段中获取一个值，并将其显示为变体价格的后缀以及自定义文本。

我在工作

• WooCommerce：从产品变体中获取自定义字段并将其显示在“附加信息区域”

• 将自定义文本添加到 Woocommerce 中的变体价格

这就是我所拥有的：

// 1. Add custom field input @ Product Data > Variations > Single Variation

add_action( 'woocommerce_variation_options_pricing', 'Add_bulk_price_to_variations', 10, 3 );

function Add_bulk_price_to_variations( $loop, $variation_data, $variation ) {  

    woocommerce_wp_text_input( array(

        'id' => 'bulk_price[' . $loop . ']',

      'desc_tip'    => 'true',

            'description' => __( 'Enter the Bulk price here.', 'woocommerce' ),

        'label' => __( 'Custom Field', 'woocommerce' ),

        'value' => get_post_meta( $variation->ID, 'bulk_price', true ) 

    ));

}

// 2. Save custom field on product variation save

add_action( 'woocommerce_save_product_variation', 'Save_bulk_price_variations', 10, 2 );

function Save_bulk_price_variations( $variation_id, $i ) {

    $bulk_price = $_POST['bulk_price'][$i];

    if ( isset( $bulk_price ) ) {

        update_post_meta( $variation_id, 'bulk_price', esc_attr( $bulk_price ) );

    }

}

// 3. Store custom field value into variation data

add_filter( 'woocommerce_available_variation', 'Add_bulk_price_variation_data' );

function Add_bulk_price_variation_data( $variations ) {  

    $variations['bulk_price'] = '<div class="woocommerce_bulk_price">Custom Field: <span>' . get_post_meta( $variations[ 'variation_id' ], 'bulk_price', true ) . '</span></div>';

    return $variations;

}

// 4. Show the bulk price on product variations

function variation_price_custom_suffix( $variation_data, $product, $variation ) {

 // Get childIDs in an array

    $children_ids = $variations->get_children();

    foreach ( $children_ids as $child_id ) {

        $value = get_post_meta( $child_id, 'bulk_price', true );

        // True

        if ( $value ) {

    $variation_data['price_html'] .= ' <span class="price-suffix">' . $value . __("custom text", "woocommerce") . '</span>';

    return $variation_data;

}

您使用相同的钩子 2x，这就足够了（不再需要第 4 步）foreach不需要使用循环来获取子 ID// 3 & 4. Store custom field value into variation data + show the bulk price on product variationsfunction add_bulk_price_variation_data( $variation_data, $product, $variation ) {&nbsp; &nbsp; $bulk_price = get_post_meta( $variation_data[ 'variation_id' ], 'bulk_price', true);&nbsp; &nbsp; if ( $bulk_price ) {&nbsp; &nbsp; &nbsp; &nbsp; $variation_data['price_html'] .= ' <span class="price-suffix">' . __( $bulk_price , "woocommerce") . '</span>';&nbsp; &nbsp; }&nbsp; &nbsp; return $variation_data;}add_filter( 'woocommerce_available_variation', 'add_bulk_price_variation_data', 10, 3 );
