获取产品变体属性值术语 ID 和名称

问题描述

在 WooCommerce 中，我使用 $product->get_variation_attributes() 来获取产品的变体属性.此函数返回一个名称不带 ID 的数组.

In WooCommerce, I'm using $product->get_variation_attributes() to get the variations attributes for a product. This function returns an array with the names without the ID's.

像这样:

                   [pa_color-shirt] => Array
                        (
                            [0] => red
                            [7] => grey
                            [14] => yellow
                        )

                    [pa_color-sweater] => Array
                        (
                            [0] => red
                            [1] => green
                            [2] => blue
                            [3] => grey
                            [4] => yellow
                            [5] => pink
                            [6] => dark-blue
                        )

对于我正在创建的 AJAX 商店，我还需要来自变体的 ID.所以我可以将 Id 和名称附加到选择框(就像 woocommerce 一样).
我搜索了几天，但找不到解决方案.

For the AJAX shop I'm creating I also need the ID's from the variations. So I can append the Id's and the names to the select boxes (Like woocommerce does).
I searched around for days but couldn't find a solution.

我创建了这个代码:

if($product->has_child()) {
                $attributes = $product->get_attributes();
                $variations = $product->get_available_variations();
                $variationsArray = array();
                foreach ($attributes as $attr => $attr_deets) {
                    $variationArray = array();
                    $attribute_label = wc_attribute_label($attr);
                    $variationArray["attribute_label"] = $attribute_label;
                    if (isset($attributes[$attr]) || isset($attributes['pa_' . $attr])) {
                        $attribute = isset($attributes[$attr]) ? $attributes[$attr] : $attributes['pa_' . $attr];
                        if ($attribute['is_taxonomy'] && $attribute['is_visible']) {
                            $variationArray["attribute_name"] = $attribute['name'];
                            $variationIds = array();
                            $variationNames = array();
                            $variationPrices = array();
                            foreach ($variations as $variation) {
                                if (!empty($variation['attributes']['attribute_' . $attribute['name']])) {
                                    array_push($variationIds, $variation['variation_id']);
                                    $taxonomy = $attribute['name'];
                                    $meta = get_post_meta($variation['variation_id'], 'attribute_'.$taxonomy, true);
                                    $term = get_term_by('slug', $meta, $taxonomy);
                                    $variation_name = $term->name;
                                    array_push($variationNames, $variation_name);
                                    array_push($variationPrices, $variation['display_regular_price']);
                                }
                            }
                            $variationArray["variation_prices"] = $variationPrices;
                            $variationArray["variations"] = array_combine($variationIds, $variationNames);
                        }
                    }
                    array_push($variationsArray, $variationArray);
                }
            }

            $product_variations = $variationsArray;

此代码返回https://hastebin.com/ecebewumoz.php

代码有效，但返回重复的名称和 ID.

The code works but returns duplicate names and id's.

我的问题是，有谁知道我如何使用 ID 来完成与 get_variation_attributes() 相同的事情?

My questions is does anyone know how I could accomplish the same as get_variation_attributes() but with the ID's?

谢谢.

推荐答案

WooCommerce 版本 3+ 的更新

Update for WooCommerce versions 3+

foreach( $product->get_variation_attributes() as $taxonomy => $terms_slug ){
    // To get the attribute label (in WooCommerce 3+)
    $taxonomy_label = wc_attribute_label( $taxonomy, $product );

    // Setting some data in an array
    $variations_attributes_and_values[$taxonomy] = array('label' => $taxonomy_label);

    foreach($terms_slug as $term){

        // Getting the term object from the slug
        $term_obj  = get_term_by('slug', $term, $taxonomy);

        $term_id   = $term_obj->term_id; // The ID  <==  <==  <==  <==  <==  <==  HERE
        $term_name = $term_obj->name; // The Name
        $term_slug = $term_obj->slug; // The Slug
        // $term_description = $term_obj->description; // The Description

        // Setting the terms ID and values in the array
        $variations_attributes_and_values[$taxonomy]['terms'][$term_id] = array(
            'name'        => $term_name,
            'slug'        => $term_slug
        );
    }
}

我在您的原始数据数组中没有看到任何重复的变体 ID……您的问题不是很清楚，因此很难猜测您正在查看的缺失 ID 是什么.然后我冒险回答，我想缺少的 ID 是来自属性值的术语 Ids...

Below WooCommerce version 3

为了获得这些条款 ID，我使用 Wordpress 函数 get_term_by()，这样:

I don't see any duplicate variations IDs in your raw data array… Your question is not very clear, so is difficult to guess what are the missing Ids you are looking at. Then I take the risk to answer and I suppose that the missing IDs are the term Ids from the attributes values…

To get this terms IDs, I use Wordpress function get_term_by(), this way:

还有:

And with:

echo '<pre>'; print_r($variations_attributes_and_values);echo '</pre>';

我将得到这个输出，每个属性的真实术语 ID 用于产品变体(我已经安排了数组输出以使其更紧凑):

I will get this output, with the real terms IDs for each attribute for a product variations (I have arranged the array output to get it more compact):

Array(
    [pa_color] => Array(
        [label] => Color
        [terms] => Array(
            [8] => Array(
                [name] => Black
                [slug] => black'
            )
            [9] => Array(
                [name] => Blue
                [slug] => blue
            )
            [11] => Array(
                [name] => Green
                [slug] => green
            )
        ) 
    )
    [pa_bulk_quantity] => Array(
        [label] => Bulk quantity
        [terms] => Array(
            [44] => Array(
                [name] => Pack of 10 dozen
                [slug] => pack-of-10-dozen
            )
            [45] => Array(
                [name] => Case of 50 dozens
                [slug] => case-of-50-dozens
            )
        )
    )
)
