我在結帳表單中添加了一個按鈕：
并在functions.php檔案中添加了一個AJAX代碼段：
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);
});
});
}
這是AJAX回調,可通過該回調以程式設計方式建立訂單：
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' => '[email protected]',
'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();
$order->update_status("Completed", 'Imported order', TRUE);
}
問題是我找不到一種方法來擷取目前的訂單資料,并在以程式設計方式建立訂單而不是目前的寫死資料時使用該資料.我需要在Checkout頁面上與目前訂單完全相同的訂單.
我正在嘗試使用WC_Checkout以及方法create_order()和get_checkout_fields(),但沒有成功.
解決方法:
對于PHP訂單建立,我使用了來自WC_Checkout create_order()方法的自定義克隆,該克隆非常有效.所有送出的資料将按順序自動設定.
對于自定義訂單中繼資料和自定義訂單項目中繼資料,可以将所有woocommerce預設挂鈎用作：
> woocommerce_checkout_create_order
> woocommerce_checkout_update_order_meta
> woocommerce_checkout_create_order_line_item
>等等…
我還對jQuery代碼進行了一些必要的更改以使其正常工作,并通過Ajax *(現在位于頁腳中)*向PHP發送了必要的格式化資料.
通過Ajax建立訂單的完整代碼：
add_action('wp_footer', 'checkout_billing_email_js_ajax' );
function checkout_billing_email_js_ajax() {
// Only on Checkout
if( is_checkout() && ! is_wc_endpoint_url() ) :
?>
jQuery(function($){
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' ) ) ) {

do_action( 'woocommerce_checkout_create_order', $order, $data );

$order_id = $order->save();

echo 'New order created with order ID: #'.$order_id.'.' ;
}
die();
