获取与WooCommerce中默认属性值相关的产品变体

问题描述

我想在我的前端模板文件中显示默认的产品属性表单值及其正常价格.

I would like to display the default product attributes form value and it's regular price in my front end template file.

下面的var_dump显示了数组中的选项. 我需要获取[default_attributes]值.

The var_dump below shows options in an array. I Need to get the [default_attributes] values.

<?php
    global $product;
    echo var_dump( $product );
// Need to get the [default_attributes] values


?>

推荐答案

要获取可变产品的默认属性，可以使用 WC_Product 方法 get_default_attributes() 这样:

To get the default attributes for a variable product you can use WC_Product method get_default_attributes() this way:

<?php
    global $product;

    if( $product->is_type('variable') ){
        $default_attributes = $product->get_default_attributes();

        // Testing raw output
        var_dump($default_attributes);
    }
?>

现在要找出哪个是默认"属性的相应产品变体，要复杂一点:

Now to find out which is the corresponding product variation for this "defaults" attributes, is a little more complicated:

<?php
    global $product;

    if( $product->is_type('variable') ){
        $default_attributes = $product->get_default_attributes();
        foreach($product->get_available_variations() as $variation_values ){
            foreach($variation_values['attributes'] as $key => $attribute_value ){
                $attribute_name = str_replace( 'attribute_', '', $key );
                $default_value = $product->get_variation_default_attribute($attribute_name);
                if( $default_value == $attribute_value ){
                    $is_default_variation = true;
                } else {
                    $is_default_variation = false;
                    break; // Stop this loop to start next main lopp
                }
            }
            if( $is_default_variation ){
                $variation_id = $variation_values['variation_id'];
                break; // Stop the main loop
            }
        }

        // Now we get the default variation data
        if( $is_default_variation ){
            // Raw output of available "default" variation details data
            echo '<pre>'; print_r($variation_values); echo '</pre>';

            // Get the "default" WC_Product_Variation object to use available methods
            $default_variation = wc_get_product($variation_id);

            // Get The active price
            $price = $default_variation->get_price();
        }
    }
?>

这已经过测试并且可以正常工作.

This is tested and works.
