php - 在 Woocommerce 3 中通过 ajax 提交并创建结帐订单

Question

我在结帐表单中添加了一个按钮:

<input type="submit" id="ajax-order-btn" class="button" value="Place Order via AJAX" />

并在 functions.php 文件中添加了一个 AJAX 片段:

add_action('wp_head', 'ajax_call_place_order');
function ajax_call_place_order() {
    ?>
    <script type="text/javascript" >
        jQuery(document).ready(function($) {
            $(document).on("click", "#ajax-order-btn" ,function(e) {
                e.preventDefault();

                var data = {
                    action: 'ajax_order',
                };

                $.post('<?php echo esc_url( home_url() ); ?>/wp-admin/admin-ajax.php', data);
            });
        });
    </script>
    <?php
}

这是 AJAX 回调，它以编程方式创建订单:

add_action('wp_ajax_ajax_order', 'ajax_order_callback_wp');
add_action( 'wp_ajax_nopriv_ajax_order', 'ajax_order_callback_wp' );
function ajax_order_callback_wp() {

    $address = array(
        'first_name' => 'John',
        'last_name'  => 'Doe',
        'company'    => 'Speed Society',
        'email'      => 'joe@testing.com',
        'phone'      => '760-555-1212',
        'address_1'  => '123 Main st.',
        'address_2'  => '104',
        'city'       => 'San Diego',
        'state'      => 'Ca',
        'postcode'   => '92121',
        'country'    => 'US'
    );


    $order = wc_create_order();

    $order->add_product( get_product('275962'), 1); // This is an existing SIMPLE product
    $order->set_address( $address, 'billing' );
    $order->calculate_totals();
    $order->update_status("Completed", 'Imported order', TRUE);
}

问题 是我找不到获取当前订单数据的方法，并且无法在以编程方式创建订单时使用该数据而不是当前的硬编码数据。我需要在结帐页面下与当前订单完全相同的订单。

我尝试使用 WC_Checkout 以及方法 create_order() 和 get_checkout_fields()，但没有成功。

Answer 1

对于 PHP 订单创建，我使用了 WC_Checkout create_order() 方法中的自定义克隆，该方法运行良好。所有提交的数据都会自动设置在订单中。

对于自定义订单元数据和自定义订单项元数据，您可以使用所有 woocommerce 默认 Hook :

• woocommerce_checkout_create_order
• woocommerce_checkout_update_order_meta
• woocommerce_checkout_create_order_line_item
• 等等……

我还对 jQuery 代码进行了一些必要的更改，使其能够很好地工作，通过 Ajax*(现在位于页脚中)* 将必要的格式化数据发送到 PHP。

Ajax创建订单的完整代码:

add_action('wp_footer', 'checkout_billing_email_js_ajax' );
function checkout_billing_email_js_ajax() {
    // Only on Checkout
    if( is_checkout() && ! is_wc_endpoint_url() ) :
    ?>
    <script type="text/javascript">
    jQuery(function($){
        if (typeof wc_checkout_params === 'undefined') 
            return false;

        $(document.body).on("click", "#ajax-order-btn" ,function(evt) {
            evt.preventDefault();

            $.ajax({
                type:    'POST',
                url: wc_checkout_params.ajax_url,
                contentType: "application/x-www-form-urlencoded; charset=UTF-8",
                enctype: 'multipart/form-data',
                data: {
                    'action': 'ajax_order',
                    'fields': $('form.checkout').serializeArray(),
                    'user_id': <?php echo get_current_user_id(); ?>,
                },
                success: function (result) {
                    console.log(result); // For testing (to be removed)
                },
                error:   function(error) {
                    console.log(error); // For testing (to be removed)
                }
            });
        });
    });
    </script>
    <?php
    endif;
}

add_action('wp_ajax_ajax_order', 'submited_ajax_order_data');
add_action( 'wp_ajax_nopriv_ajax_order', 'submited_ajax_order_data' );

        // Loop through posted data array transmitted via jQuery
        foreach( $_POST['fields'] as $values ){
            // Set each key / value pairs in an array
            $data[$values['name']] = $values['value'];
        }

        $cart_hash          = md5( json_encode( wc_clean( $cart->get_cart_for_session() ) ) . $cart->total );

        // Loop through the data array

代码进入事件子主题(或事件主题)的 function.php 文件。经过测试并有效。
