Woocommerce支付网关集成

最新的woocommerce版本支付网关集成有问题 . 我最近开始使用woocommerce为朋友，他有woocommerce版本1.6.5.2 . 但现在他将他的woocommerce更新到最新版本（2.0.12） . 他有一些定制的支付网关，适用于1.6版本，但现在它没有 . 这是自定义支付网关代码：

/*

$post_perma = trim( esc_url ( $_SERVER['REQUEST_URI'] ), '/' );
add_action('plugins_loaded', 'woocommerce_rba_etomitreba_init', 0);
if($post_perma == 'uspjeh'||$post_perma == 'greska') {
    add_filter('the_content', 'after_processing');
}
function after_processing() {
    global $post, $post_perma, $woocommerce;
    if($post_perma == 'uspjeh') {
        if(isset($_POST['OrderID'])&&isset($_POST['ApprovalCode'])) {
            echo '<div class="notify notify-success">Not Important;)</div>';
            $order = new WC_Order( $_POST['OrderID'] );

}

它只是一个兼容性问题，但正如我所说，我是woocommerce新手，并没有经验丰富的PHP . 任何帮助将不胜感激 .
