从控制器文件发送 Yandex Money 表单

一个欢乐的夜晚！

我的任务：用户转到使用 Yandex 货币付款的页面。该站点必须将数据写入客户在表格中输入的数据库，并使用他输入的参数将他重定向到 Yandex Money 网站。如果我完成了第一个任务，那么我不知道如何进一步发送用户。它应该采用以下形式：

<form method="POST" action="https://money.yandex.ru/quickpay/confirm.xml"> 
    <input type="hidden" name="receiver" value="410013229143888"> 
    <input type="hidden" name="formcomment" value="Оплата через AIVA">
    <input type="hidden" name="quickpay-form" value="shop"> 
    <input type="hidden" name="targets" value="Оплата по счету"> 
    <input type="hidden" name="need-fio" value="false"> 
    <input type="hidden" name="need-email" value="false"> 
    <input type="hidden" name="need-phone" value="false"> 
    <input type="hidden" name="need-address" value="false"> 
    <input type="hidden" name="paymentType" value="PC">

    <input type="email" name="short-dest" class="form-control" id="exampleInputEmail1" placeholder="mail@mail.ru">
    <input type="text" id="comment" name="comment" class="form-control" id="exampleInputEmail1" placeholder="Необязательное поле">
    <input type="text" name="sum" class="form-control" id="exampleInputEmail1" value="200">

    <button type="submit" class="btn btn-primary">ок</button>
</form>

查看文件

<?php echo form_open(site_url("payment/add_card_yandex_pro/"), array("" => "")) ?>


          <input type="email" name="short-dest" class="form-control" id="exampleInputEmail1" placeholder="mail@mail.ru">
          <input type="text" id="comment" name="comment" class="form-control" id="exampleInputEmail1" placeholder="Необязательное поле">
          <input type="text" name="sum" class="form-control" id="exampleInputEmail1" value="200">

          <button type="submit" class="btn btn-primary">ок</button>
      <?php echo form_close() ?>

控制器文件

public function add_card_yandex_pro()
{
    // Сохранение действия в истории операций
    $pay_method  = "Банковские карты Яндекс";
    $transaction = $this->common->nohtml($this->input->post("targets"));
    $name = $this->common->nohtml($this->input->post("formcomment"));
    $amount = $this->common->nohtml($this->input->post("sum"));
    $email = $this->common->nohtml($this->input->post("short-dest"));
    $comment = $this->common->nohtml($this->input->post("comment"));

    if(empty($name)) {
        $this->template->error(lang("error_79"));
    }


        $historyid = $this->payment_model->add_card_yandex(array(
        "pay_method" => $pay_method,
        "transaction" => $transaction,
        "name" => $name,
        "amount" => $amount,
        "email" => $email,
        "comment" => $comment,
        "timestamp" => time()
        )
    );

    $this->session->set_flashdata("globalmsg", lang("success_40"));
    redirect(site_url("pay_link"));

}

如何在控制器中正确编写表单？很高兴并感谢任何帮助或指导。
