我在结帐表单中添加了一个按钮：

并在functions.php文件中添加了一个AJAX代码段：

add_action('wp_head', 'ajax_call_place_order');

function ajax_call_place_order() {

?>

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);

});

});

}

这是AJAX回调,可通过该回调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);

}

问题是我找不到一种方法来获取当前的订单数据,并在以编程方式创建订单而不是当前的硬编码数据时使用该数据.我需要在Checkout页面上与当前订单完全相同的订单.

我正在尝试使用WC_Checkout以及方法create_order()和get_checkout_fields(),但没有成功.

解决方法:

对于PHP订单创建,我使用了来自WC_Checkout create_order()方法的自定义克隆,该克隆非常有效.所有提交的数据将按顺序自动设置.

对于自定义订单元数据和自定义订单项目元数据,可以将所有woocommerce默认挂钩用作：

> 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以使其正常工作,并通过Ajax *(现在位于页脚中)*向PHP发送了必要的格式化数据.

通过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() ) :

?>

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)

}

});

});

});

endif;

}

add_action('wp_ajax_ajax_order', 'submited_ajax_order_data');

add_action( 'wp_ajax_nopriv_ajax_order', 'submited_ajax_order_data' );

function submited_ajax_order_data() {

if( isset($_POST['fields']) && ! empty($_POST['fields']) ) {

$order = new WC_Order();

$cart = WC()->cart;

$checkout = WC()->checkout;

$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 );

$available_gateways = WC()->payment_gateways->get_available_payment_gateways();

// Loop through the data array

foreach ( $data as $key => $value ) {

// Use WC_Order setter methods if they exist

if ( is_callable( array( $order, "set_{$key}" ) ) ) {

$order->{"set_{$key}"}( $value );

// Store custom fields prefixed with wither shipping_ or billing_

} elseif ( ( 0 === stripos( $key, 'billing_' ) || 0 === stripos( $key, 'shipping_' ) )

&& ! in_array( $key, array( 'shipping_method', 'shipping_total', 'shipping_tax' ) ) ) {

$order->update_meta_data( '_' . $key, $value );

}

}

$order->set_customer_ip_address( WC_Geolocation::get_ip_address() );

$order->set_customer_user_agent( wc_get_user_agent() );

$order->set_customer_note( isset( $data['order_comments'] ) ? $data['order_comments'] : '' );

$order->set_payment_method( isset( $available_gateways[ $data['payment_method'] ] ) ? $available_gateways[ $data['payment_method'] ] : $data['payment_method'] );

$order->set_shipping_total( $cart->get_shipping_total() );

$order->set_discount_total( $cart->get_discount_total() );

$order->set_discount_tax( $cart->get_discount_tax() );

$order->set_cart_tax( $cart->get_cart_contents_tax() + $cart->get_fee_tax() );

$checkout->create_order_fee_lines( $order, $cart );

$checkout->create_order_shipping_lines( $order, WC()->session->get( 'chosen_shipping_methods' ), WC()->shipping->get_packages() );

$checkout->create_order_tax_lines( $order, $cart );

$checkout->create_order_coupon_lines( $order, $cart );

/**

do_action( 'woocommerce_checkout_update_order_meta', $order_id, $data );
