WooCommerce：为产品变体添加自定义字段

I need help adding custom fields to my Product Variations and Simple Product pages. I tried using RemiCorson's info (http://www.remicorson.com/woocommerce-custom-fields-for-variations/), but I keep getting an error. I tried to duplicate what I saw in this user's posts for ISBN but it's not working for me.

我需要帮助将自定义字段添加到“产品变体”和“简单产品”页面中。我尝试使用RemiCorson的信息(http://www.remicorson.com/woocommerce-custom-fields-for-variations/),但我一直收到错误。我试图复制我在这个用户的帖子中看到的ISBN,但它对我不起作用。

The problem with the code below is that it doesn't show up on the live site. All help is greatly appreciated, I've spent most of today trying to figure out what I'm doing wrong.

下面的代码的问题是它不会显示在实际站点上。所有的帮助都非常感谢,我今天大部分时间都在努力弄清楚我做错了什么。

Adding 6 custom text fields and 1 check box to both Simple Product and Variable Product pages in Woocommerce. These are not fields to be supplied (i.e. filled out) by the shopper, but rather custom information I want displayed on my product pages (and NOT within a tab).

在Woocommerce中的简单产品和可变产品页面中添加6个自定义文本字段和1个复选框。这些不是购物者提供(即填写)的字段,而是我希望在我的产品页面上显示的自定义信息(而不是在标签内)。

// Display Fields
add_action( 'woocommerce_product_options_general_product_data', 'woo_add_custom_general_fields' );

// Save Fields
add_action( 'woocommerce_process_product_meta', 'woo_add_custom_general_fields_save' );

function woo_add_custom_general_fields() {

  global $woocommerce, $post;

  echo '<div class="options_group">';

  // Custom fields will be created here...

// Text Field
woocommerce_wp_text_input( 
    array( 
        'id'          => '_ISBN_field', 
        'label'       => __( 'ISBN', 'woocommerce' ), 
        'placeholder' => '',
        'desc_tip'    => 'true',
        'description' => __( 'ISBN.', 'woocommerce' ) 
    )
);
function woo_add_custom_general_fields_save( $post_id ){

// Customer text ISBN Field
$woocommerce_text_field = $_POST['_ISBN_field'];
if( !empty( $woocommerce_text_field ) )
    update_post_meta( $post_id, '_ISBN_field', esc_attr( $woocommerce_text_field ) );
else
    update_post_meta( $post_id, '_ISBN_field', '' );
}
// Display Custom Field Value
echo get_post_meta( $post->ID, '_ISBN_field', true );

}

I have never needed to bother with woocommerce_product_after_variable_attributes_js, you just need to add the input and then deal with saving it.

我从来不需要打扰woocommerce_product_after_variable_attributes_js,你只需要添加输入然后处理保存它。

Another thing that has changed since Remi's article was published is that the WooCommerce variation meta data is no longer printed in a <Table> element... and is now a <div> element. This is important for how you structure your new content.

自Remi发表文章以来发生变化的另一件事是,WooCommerce变体元数据不再打印在

元素。这对于构建新内容非常重要。

元素中......现在是

Here's is how you'd add a meta field to a variation:

以下是为元变量添加元字段的方法:

// regular variable products
add_action( 'woocommerce_product_after_variable_attributes', 'add_to_variations_metabox', 10, 3 );
add_action( 'woocommerce_save_product_variation', 'save_product_variation', 20, 2 );


/*
 * Add new inputs to each variation
 *
 * @param string $loop
 * @param array $variation_data
 * @return print HTML
 */
function add_to_variations_metabox( $loop, $variation_data, $variation ){

    $custom = get_post_meta( $variation->ID, '_custom', true ); ?>

        <div class="variable_custom_field">
            <p class="form-row form-row-first">
                <label><?php echo __( 'Custom Data:', 'plugin_textdomain' ); ?></label>
                <input type="text" size="5" name="variation_custom_data[<?php echo $loop; ?>]" value="<?php echo esc_attr( $custom ); ?>" />
            </p>
        </div>

    <?php 

}

/*
 * Save extra meta info for variable products
 *
 * @param int $variation_id
 * @param int $i
 * return void
 */
function save_product_variation( $variation_id, $i ){

    // save custom data
    if ( isset( $_POST['variation_custom_data'][$i] ) ) {
        // sanitize data in way that makes sense for your data type
        $custom_data = ( trim( $_POST['variation_custom_data'][$i]  ) === '' ) ? '' : sanitize_title( $_POST['variation_custom_data'][$i] );
        update_post_meta( $variation_id, '_custom', $custom_data );
    }

}
