如何通过 woocommerce 中的属性获取变体 ID

Question

我想在用户点击我的属性时找到ID并可验证，请帮助。例如，我们有两个属性：区域 = ars 充值金额=100ars

当两者都选择时，必须返回一个有效的ID

我的代码：

<?php $attributes = $product->get_attributes() // GET ALL ATRIBUTES ?>
                        <?php foreach ($attributes as $key => $value): ?>
                            <?php $attribute_name_ = preg_replace('/pa_/', '', $key); // GET ATTRIBUTE NAME


                            ?>

                            <div class="<?= ($attribute_name_ == 'regions') ? 'region' : 'charge'; ?>">


                                <?php $attribute_name = wc_get_product_terms(get_the_ID(), $key);

                                $attribute_slug = wc_get_product_terms(get_the_ID(), $key, array('fields' => 'slugs')); // GET ATTRIBUTE SLUG


                                ?>
                                <?php for ($i = 0; $i < count($attribute_name); $i++): // array_slice BECAUSE ARRAY INDEX IS NOT SEQUENCIAL

                                    $slug = array_slice($attribute_slug, $i, 1);


                                    $atribute_list = [];
                                    if ($attribute_name_ == 'regions') {

                                        $atribute_list['attribute_pa_regions'] = $slug['0'];
                                    }
                                    if ($attribute_name_ == 'charge-amount') {
                                        $atribute_list['attribute_pa_charge-amount'] = $slug['0'];
                                    }

//                                    echo find_matching_product_variation_id($product, $atribute_list);


                                    ?>


                                    <?php
                                    if ($attribute_name_ == 'regions') {


                                        ?>
                                        <div id="<?= $slug['0'] ?>"
                                             class="region-item">

                        $name = array_slice($attribute_name, $i, 1);
                        echo $name[0]->name;

                                    if ($attribute_name_ == 'charge-amount') {

                                        $atribute_list['attribute_pa_charge-amount'] = $slug['0'];
                                        ?>

                                        <div id="<?= $slug['0'] ?>"
                                             class="charge-item">

                                            <?php

                                            $name = array_slice($attribute_name, $i, 1);
                                            echo $name[0]->name;

                                            ?>

                                        </div>
                                        <?php

                            </div>
                        <?php endforeach ?>

我这里只单独显示属性，现在我想在点击相关属性时显示ID和可验证信息或包含在一个变量中。

我的代码输出是这样的：

Answer 1

我是这样解决问题的我创建了一个函数，它使用产品 ID 和国家/地区属性 ID 提取其收费金额的属性，并使用 Ajax 调用。然后通过另一个功能发送价格和有关收费金额的信息，最后就可以了

我的鳕鱼：

我的功能：

        $regions = $available_variation['attributes']['attribute_pa_regions'];
        $varible_id = $available_variation['variation_id'];
        $charge = $available_variation['attributes']['attribute_pa_charge-amount'];
        $display_price = $available_variation['display_price'];


        $pa_charge_amount_ = 'pa_charge-amount';
        $pa_charge_amount_meta = get_post_meta($available_variation['variation_id'], 'attribute_' . $pa_charge_amount_, true);
        $pa_charge_amount_term = get_term_by('slug', $pa_charge_amount_meta, $pa_charge_amount_);


        if ($region_id === $regions) {

            $vari_g[] = array(
                'group' => $region_id,

                'name' => $pa_charge_amount_term->name,
            );

            $html = '<div id="' . $varible_id . '" class="charge-item">' . $pa_charge_amount_term->name . '</div>';

            echo $html;
        }
    }

    wp_die();

}

add_action("wp_ajax_get_varible_data", "get_varible_data");
add_action("wp_ajax_nopriv_get_varible_data", "get_varible_data");

function get_varible_ch_data()
{


    $variation_id = $_POST['charge_id'];
    $price = get_post_meta($variation_id, '_price', true);

    echo $price;

    wp_die();

}

add_action("wp_ajax_get_varible_ch_data", "get_varible_ch_data");
add_action("wp_ajax_nopriv_get_varible_ch_data", "get_varible_ch_data");

和我的 ajax :

<script>

            function request_ajax_call_varible(metodth, id) {

                $('.card-buy').css('cursor', 'wait');
