CodeIgniter：显示动态错误

Question

更新：

RJZ：

TdjxQetc 是来自数据库的$activateCode，所以当我运行 /confirm/ 时，我应该会感到抱歉，您没有正确的激活码，因为我没有传入任何 var ($activateCode) 但是当我运行 /confirm/$activateCode 时，我应该得到谢谢，您的帐户现在处于活动状态，您可以登录！并使用 else 语句

我在想应该改一下，开发一个新的模型函数来检查userActive是否已经设置为1，然后再显示另一个$message，这样就只能使用链接了。

查看：

<div class = "messages">
    <?php if($confirmMessage != ''): ?>
        <?php if($confirmError): ?>
            <p class="error">
                <?php echo $confirmMessage; ?>
                </p>
                <?php else: ?>
                    <p class="message">
                        <?php $confirmMessage?>
                        </p>
                        <?php endif; ?>
                        <?php endif; ?>
    </div>

控制器：

function confirm(){

        $activateCode = $this->uri->segment(3);
        $error = FALSE;
        $message = '';

        if($activateCode == '')
        {
            $error = TRUE;
            $message = 'Sorry you did not have a correct Activation Code.';
        }
            $userConfirmed = $this->users_model->confirm_user($activateCode);

            if($userConfirmed){
                $message = 'Thanks your account is now active you may login!';
            }else{
                $error = TRUE;
                $message = 'I am sorry we do not have any details with that Activation Code';
            }
            $data['companyName'] = $this->core_model->companyDetails()->coreCompanyName;
            $data['pageTitle'] = "User Confirm";
            $data['confirmError'] = $error;
            $data['confirmMessage'] = $message;
            $this->load->view('frontend/assets/header', $data);
            $this->load->view('frontend/user_confirm', $data);
            $this->load->view('frontend/assets/footer');
    }

我不确定为什么我没有收到验证消息，我只是了解我的观点。数据库正在更新到 1。

查看：

<h1><?php echo $companyName; echo nbs(1);?> - <?php echo $pageTitle; ?></h1>

    <p>Error: <?php echo validation_errors();?></p>

控制器：

function confirm(){

        $activateCode = $this->uri->segment(3);

        if($activateCode == '')
        {
            $this->form_validation->set_message('userConfirmError', 'Sorry you did not have a correct Activation Code.');
        }
            $userConfirmed = $this->users_model->confirm_user($activateCode);

            if($userConfirmed){
                $this->form_validation->set_message('userConfirmed', 'Thanks your account is now active you may login!');
            }else{
                $this->form_validation->set_message('userRecord', 'I am sorry we do not have any details with that Activation Code');
            }
            $data['companyName'] = $this->core_model->companyDetails()->coreCompanyName;
            $data['pageTitle'] = "User Confirm";
            $this->load->view('frontend/assets/header', $data);
            $this->load->view('frontend/user_confirm', $data);
            $this->load->view('frontend/assets/footer');
    }

确认功能：

function confirm_user($activateCode)
    {
     //Selects the userID where the given URI activateCode = ?

        $this->db->select('userID');
        $this->db->from('users');
        $this->db->where('userActiveCode', $activateCode);

        $result = $this->db->get();

        if($result->num_rows == 1)  // If the above result is = 1 then update the userActive row else it will fail
        {
            $this->db->set('userActive', 1);
            $this->db->where('userActiveCode', $activateCode);

            return TRUE;
        }else{
            return FALSE;
        }

核心模型：

function companyDetails()
    {
        static $details;

        if(!$details)
        {
            $this->db->select('coreCompanyName, coreContactName, coreContactEmail');
            $details = $this->db->get('core')->first_row();
        }
        return $details;
    }

Jess，你有点像在鼹鼠山上造山。让我们看看我们可以做些什么来清理它：

控制器方法

function confirm()
{
    $activate_code = $this->uri->segment(3);

    if(!$this->users_model->confirm_user($activate_code))
        $error = true;
    else
        $error = false;

    $data['companyName'] = $this->core_model->companyDetails()->coreCompanyName;
    $data['pageTitle'] = "User Confirm";
    $data['confirmError'] = $error;
    $this->load->view('frontend/assets/header', $data);
    $this->load->view('frontend/user_confirm', $data);
    $this->load->view('frontend/assets/footer');
}

查看

<div class = "messages">
    <?php if($confirmError): ?>
        <p class="error">
            Your activation code is invalid.
        </p>
    <?php else: ?>
         <p class="message">
            Your account has been activated.
         </p>
    <?php endif; ?>
</div>

请将此代码添加到您的 UserModel::confirm_user 方法的顶部：

if($activateCode == '')
   return false;

我已将您的控制器方法简化为只有两种情况——成功或错误。无需检查 activate_code，因为您的模型正在为您执行此操作。

此外，我更喜欢将仅在它们所属的视图中使用的字符串保留在视图中。

Answer 2

如果您还没有，您确实需要在视图文件中调用 validation_errors() 帮助程序（或 Codeigniter 的其他帮助程序之一以生成错误）。

// in view file
<form>
  <?php echo validation_errors(); ?>
  <!-- rest of form... -->
</form>

如果您调用 validation_errors() 仍然没有看到输出，这可能是因为验证没有运行。在调用视图之前，您需要运行表单验证：

// in controller action function
$this->form_validation->run();

使用您在上面提供的代码，仍然无法解决问题——您实际上还没有设置任何验证规则。您需要阅读validation guide，但一般方法如下所示：

// in controller action function
$this->form_validation->add_rules('my_field', 'My Field Name', 'required');
$this->form_validation->run();

您可能想知道add_rules 实际测试的是什么。在 Codeigniter 中，它通常设计用于处理来自表单的任何表单数据$_POSTed。直接在模型上使用它（就像你正在尝试做的那样）需要一些黑客攻击，并且使用标志变量和消息字符串可能是最简单的：

function confirm($activateCode = '') {

  $error = false;
  $message = '';

  if($activateCode == '')
  {
    $error = true;
    $message = 'Sorry you did not have a correct Activation Code.';
  }

  $userConfirmed = $this->users_model->confirm_user($activateCode);

  if($userConfirmed)
  {
    $message = 'Thanks your account is now active you may login!';
  }
  else
  {
    $error = true;
    $message = 'I am sorry we do not have any details with that Activation Code';
  }

  $data['error'] = $error;
  $data['message'] = $message
}

在视图中：

<?php if ($message != ''): ?>
<?php if ($error): ?>
  ERROR: <?php echo $message; ?>
<?php else: ?>
  SUCCESS: <?php echo $message; ?>
<?php endif; ?>
<?php endif; ?>
