代码点火器表单验证将不会运行

似乎存在关于表单和表单验证的问题。

我在表单验证工作中遇到了问题。我创建了一个注册表格，要求用户提供各种信息。然后我创建了一个表单，允许用户编辑他的信息。表单验证在注册表单上非常有效，但我无法让它在其他表单上运行验证。

我的视图

<h1>Edit user</h1>
<div id="body">
        <p>Edit user information.</p>
    <?php 

    echo form_open('user_admin/user_update');
    echo validation_errors();
    echo form_hidden('id', $results->id);
    echo "<p><lable>Email:</lable>";
    echo form_input('email', $results->email);
    echo "</p>";

    echo "<p><lable>Name:</lable>";
    echo form_input('name', $results->name);
    echo "</p>";
    echo "<p><lable>Last name:</lable>";
    echo form_input('lastname', $results->lastname);
    echo "</p>";
    echo "<p><lable>Home address:</lable>";
    echo form_textarea('homeaddress', $results->homeaddress);
    echo "</p>";
    echo "<p><lable>Postal address:</lable>";
    echo form_textarea('posteladdress', $results->posteladdress);
    echo "</p>";
    echo "<p><lable>Mobile number:</lable>";
    echo form_input('mobile', $results->mobile);
    echo "</p>";
    echo "<p><lable>Home telephone:</lable>";
    echo form_input('hometel', $results->hometel);
    echo "</p>";
    echo "<p><lable>ID number:</lable>";
    echo form_input('idnum', $results->idnum);
    echo "</p>";
    echo "<p>";
    echo form_submit('edit_submit', 'Update');
    echo "</p>";
    echo form_close();
    ?> 

我的控制器

 public function user_update()
{
    $this->load->library('form_validation');
    $this->load->model('model_users');
    $this->form_validation->set_rules('email', 'Email', 'required|trim|valid_email|is_unique[user.email]');
    $this->form_validation->set_rules('name', 'Name', 'required|trim');
    $this->form_validation->set_rules('lastname', 'Last name', 'required|trim');
    $this->form_validation->set_rules('homeaddress', 'Home address', 'required|trim');
    $this->form_validation->set_rules('posteladdress', 'Postel address', 'required|trim');
    $this->form_validation->set_rules('mobile', 'Mobile number', 'required|trim');
    $this->form_validation->set_rules('hometel', 'Home telphone', 'required|trim');
    $this->form_validation->set_rules('idnum', 'ID Number', 'required');

    $this->form_validation->set_message('is_unique', 'This email address has already been registered. Please try again.');
    if ($this->form_validation->run()==true)
    {
        $id = $this->input->post('id');
        $this->model_users->update_info();
        echo "The users details have been updated successfully";
        redirect ('user_admin/user_main');
    }
    else
    {
        echo "The users details were not updated. Please contact the admistrator!";

    }

}

在控制器处于当前配置的情况下，我可以通过将if语句更改为FALSE来更新数据库。所以我现在将帖子信息传递到数据库并进行更新。

请有人看看我的代码，告诉我我做错了什么。

谢谢。
