笨：显示动态误差

Question

更新时间：

RJZ：

TdjxQetc是来自于数据库，所以当我运行/确认/我应该得到对不起，你没拥有的$activateCode正确的激活码，因为我没有通过任何变种（$activateCode），但是当我运行/确认/ $activateCode我应该得到感谢您的帐户现在活动，您可以登录！并与else语句

我想它应该被改变，一个新的模型功能的开发，以检查是否userActive已被设置为1，然后显示另一个$message，这样的链接才能使用。

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确认邮件，我只是得到我的观点。该数据库更新为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; 
     } 

核心型号：

function companyDetails() 
    { 
     static $details; 

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

Answer 1

你是种在这里的一个山痣山这里杰斯。让我们看看我们能做些什么来打扫一下：

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顶部:: confirm_user方法：

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

我将控制器方法简化为只有两种情况 - 成功或错误。没有必要检查activate_code，因为你的模型正在为你做。

此外，我更愿意保留仅在视图中使用的视图中的字符串 - 在视图中。

Answer 2

如果您还没有准备好，你就需要调用validation_errors()助手（或笨的其他助手的错误产生的一个）在你的视图文件。

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

如果你调用validation_errors()，仍然没有看到输出，这可能是因为验证未运行。在此之前调用视图，你需要运行表单验证：

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

随着您在上面提供的代码，仍然不会很后事 - 你还没有真正建立了验证任何规则。你会想在validation guide读了，但一般的方法是这样的：

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

你可能想知道add_rules实际测试。在Codeigniter中，它通常设计用于处理来自表单的任何表单数据$_POST。要使用它直接在模型（因为它看起来就像你正在试图做的）会采取一些黑客，它可能是最简单的只使用一个标志变量和消息字符串：

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 
} 

鉴于：

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