产品页面的额外行/文本字段(WooCommerce)

时间：2017-03-07 作者：TimVanGorp

对于各位专家来说，这是一个简单的问题，但我一直在搜索，找不到准确的工作指南。所以我非常希望有人知道处理这件事的最佳方法：

我想为每个产品（它们是可变产品，不确定这是否重要）添加一个唯一的文本字段，我可以在产品的后端输入文本。此文本将显示在选项卡上方的前端，最好显示在自己创建的行中。

这应该能够完成这些功能。我的孩子主题的php。我已经收集了这些信息来启用后端的文本字段，但它似乎对我不起作用（可能是因为使用了可变产品或最新的Wordpress版本）：

// 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_save( $post_id ){

    // Textarea
    $woocommerce_textarea = $_POST[\'_textarea\'];
    if( !empty( $woocommerce_textarea ) )
        update_post_meta( $post_id, \'_textarea\', esc_html( $woocommerce_textarea ) );

}

问题不在于可变产品。这是一个单独的选项卡。因此，如果要在“常规”选项卡中添加自定义字段，它不会影响“变量”选项卡或任何其他选项卡。

但是，我将为您提供更新的产品代码，以添加自定义字段。我正在显示常规数据、变量数据和自定义选项卡字段。

如果要使用函数。php，将我的代码放入函数中。php。

要获取这些值，我们只需要使用流行的get\\u post\\u meta（）函数。

<?php
// Display Custom Field Value
echo get_post_meta( $post->ID, \'my-field-slug\', true );
ex. echo get_post_meta( $post->ID, \'_textarea\', true );
// You can also use
echo get_post_meta( get_the_ID(), \'my-field-slug\', true );
ex. echo get_post_meta( get_the_ID(), \'_textarea\', true );

// variable data 
ex. echo get_post_meta( $variation->ID, \'_textarea\', true );
?>

代码经过测试，运行良好。如果你在任何地方遇到麻烦，请不要犹豫，再问任何问题。如果您需要帮助为shipping选项卡或任何其他选项卡添加自定义字段，请告诉我，我将在将来更新代码。

注意。插件和函数的代码。php是相同的。您可以使用任一函数。php或自定义插件代码。
