我很抱歉，但代码元素并没有为此工作。上面的文字是我的代码，我想在提交成功时重置表单，但在有验证错误时保留其中的内容。

控制器代码： -

public function register(){
    // Set up the form
    $rules = $this->user_m->rules_admin;
    $rules['password']['rules'] .= '|required';
    $this->form_validation->set_rules($rules);
    $this->form_validation->set_message('required', 'This field is required');
    $this->form_validation->set_error_delimiters('<small class="text-danger txt-upper">', '</small>');

    // Process the form
    if ($this->form_validation->run() == TRUE) 
    {
        if($this->user_m->add_user())
        {
            $this->data['message']= "You are registered successfully. Please login" ;


        }

        else
        {
            $this->data['message']= "Failed to register";
        }

    }
                $this->data['subview'] = 'home/login';
                $this->load->view('_layout_main_1', $this->data);
            //  $this->load->view('home/login', $this->data);
        }

Answer 1

当您遇到错误并在表单中显示值时，最好使用会话数组。但如果您有错误，只需重定向它，您的表单将在提交后重置。

Answer 2

你的控制器代码需要改变如下（我猜，你已经知道了）：

   // Process the form
if ($this->form_validation->run() == TRUE) 
{
    if($this->user_m->add_user())
    {
        $this->data['message']= "You are registered successfully. Please login" ;
     // Call login screen here, for example :
     redirect('login', 'location');

    }

    else
    {
        $this->data['message']= "Failed to register";
    }

}

更改表单代码，如下所示:(删除对set_value的调用）

            <td class="login-textfield">
            <?php echo form_input( 'phone','', ' placeholder="Phone Number", class="background-grey" id="phone" required id="phone"')?>
            <?php echo form_error( 'phone'); ?>

说明：在form_validation失败时 - code_igniter尚未退出表单，因此在不使用set_value的情况下仍可使用在字段中输入的值。

成功注册后，当您转移到新表单时，您并不在意 - 登录表单。

尝试一下，让我知道它是否有效。
