WooCommerce在可变价格后显示可变描述 [英] WooCommerce displaying variable description after variable price

问题描述

我正在尝试将变量描述显示到woocommerce产品页面中. 我安装了一个名为woocommerce单选按钮的插件，用于将我的可变产品和价格显示为单选按钮而不是单选按钮.

I'm trying to display the variable description into a woocommerce product page. I installed a plugin named woocommerce radio buttons, for displaying my variable products and prices as a radio button instead of a select.

我正在此插件中编辑variable.php文件(完成后将其传输到我的子主题中)，基本上我需要将变量描述显示在标签中，作为名为$ variable_description的变量.

I am editing the variable.php file, in this plugin (then I will transfer it to my child theme once finished) and basically I need to show the variable description into a label, as a variable named $variable_description.

    printf( '<div>
    <input type="radio" name="%1$s" value="%2$s" id="%3$s" %4$s>
    <label for="%3$s">%5$s</label>
    <label>'.$variable_description.'</label>
    </div>', $input_name, $esc_value, $id, $checked, $filtered_label );

由于我不了解的数据库结构，我无法从数据库中恢复此数据.

I am not able to recover this data from the database, because of the structure of the database that I don't understand.

您知道任何短码或短码来恢复它并显示每个可变价格的变量描述吗?

Do you know any shortcode or function to recover it and displaying the variable description for each variable price?

在我正在编辑的功能中，单选按钮旁边的每个变体的价格正确显示为第一个标签.该函数的完整代码为:

In the function I'm editing the price is correctly displayed for each variation next to the radio button as the first label. The full code of the function is:

if ( ! function_exists( 'print_attribute_radio' ) ) {
    function print_attribute_radio( $checked_value, $value, $label, $name, $product_id ) {

        // This handles < 2.4.0 bw compatibility where text attributes were not sanitized.
        $checked = sanitize_title( $checked_value ) === $checked_value ? checked( $checked_value, sanitize_title( $value ), false ) : checked( $checked_value, $value, false );

        $input_name = 'attribute_' . esc_attr( $name ) ;
        $esc_value = esc_attr( $value );
        $id = esc_attr( $name . '_v_' . $value );
        $filtered_label = apply_filters( 'woocommerce_variation_option_name', $label );

    //here is where I try to recover the variable_description

        global $wpdb;
        $post_id = $product_id + 3;

         $querystr = "SELECT wpostmeta.meta_value
                    FROM $wpdb->postmeta wpostmeta
                    WHERE wpostmeta.post_id = '$post_id'
                    AND wpostmeta.meta_key = '_variation_description'
                    ORDER BY wpostmeta.meta_value DESC
                    "; 


     $variable_description = $wpdb->get_var($querystr);

        printf( '<div>
        <input type="radio" name="%1$s" value="%2$s" id="%3$s" %4$s>
        <label for="%3$s">%5$s</label>
        <label>'.$variable_description.'</label>
        </div>', $input_name, $esc_value, $id, $checked, $filtered_label );

    }
}

谢谢

推荐答案

要获取帖子元数据，可以使用

To get post meta data you can use WordPress get_post_meta() function instead (It's much shorter and affordable).

因此您的代码应为:

if ( ! function_exists( 'print_attribute_radio' ) ) {
    function print_attribute_radio( $checked_value, $value, $label, $name, $product_id ) {

        // This handles < 2.4.0 bw compatibility where text attributes were not sanitized.
        $checked = sanitize_title( $checked_value ) === $checked_value ? checked( $checked_value, sanitize_title( $value ), false ) : checked( $checked_value, $value, false );

        $input_name = 'attribute_' . esc_attr( $name ) ;
        $esc_value = esc_attr( $value );
        $id = esc_attr( $name . '_v_' . $value );
        $filtered_label = apply_filters( 'woocommerce_variation_option_name', $label );

        // HERE the product variation description
        $variation_id = $product_id + 3;
        $variable_description = get_post_meta( $variation_id, '_variation_description', true );

        printf( '<div>
        <input type="radio" name="%1$s" value="%2$s" id="%3$s" %4$s>
        <label for="%3$s">%5$s</label>
        <label>'.$variable_description.'</label>
        </div>', $input_name, $esc_value, $id, $checked, $filtered_label );
    }
}
