[Wordpress] WooCommerce 自訂頁面呼叫相關API

今天要在自訂的php頁面呼叫wc的api記錄，因為老闆說要另外做一頁就這樣搞了XD不要問

載入WP的函式庫

require_once(dirname(dirname(__FILE__)).'/wp-load.php');

取得指定產品id的清單，並且支援i18n

/*
簡: zh-hans
繁: zh-hant
*/
if(isset($_GET['lang'])){
  $currentLang = $_GET['lang'];
}else{
  $currentLang = 'en';
}

$_pf = new WC_Product_Factory();  

foreach ($related_product_ids as $id) {

  $translate_post_id = icl_object_id($id, 'product', FALSE,$currentLang);

   $_product = $_pf->get_product($translate_post_id);
  // echo $id;
   // echo ($_product->get_image());
   var_dump($_product);
}

模擬paypal post動作

執行payal的按鈕後就會產生一筆訂單到用戶資料了，看post是打checkout的api (checkout/?wc-ajax=checkout)

追了一下相關要看的source code如下

• WC_Gateway_Paypal ( includes/class-wc-gateway-paypal.php)

其呼叫process_payment方法後會產生paypal 結帳頁面url

• WC_Gateway_Paypal_Request (includes/class-wc-gateway-paypal-request.php)

呼叫 get_request_url會產生paypal結帳url


最後找到一個不錯外掛(https://wp-ecommerce.net/paypal-pro-payment-gateway-for-woocommerce)範例比較符合需求

如要自已幹api可參考，目前也決定自幹API
