在顯示自定義標題之前需要刷新Codeigniter頁面？

Question

我碰到過最奇怪的問題。

我創建了一些自定義標題和落實Facebook開源圖形meta標籤的分享

<meta name="description" content="<?php echo $metadescription; ?>" />    
     <meta property="og:title" content="<?php echo $title; ?>" /> 
     <meta property="og:type" content="article"/> 
     <meta property="og:url" content="<?php echo $imageurl; ?>" /> 
     <?php if ($adult == '1' && !$this->auth->loggedin()) : ?>     
      <meta property="og:image" content="<?php echo base_url(); ?>assets/images/fotoleaf-adult-image.jpg" /> 
     <?php else : ?>     
      <meta property="og:image" content="<?php echo $image; ?>" /> 
     <?php endif; ?> 
     <meta property="og:description" content="<?php echo $metadescription; ?>" /> 

     <!-- Twitter Card data --> 

     <meta name="twitter:card" content="summary"> 
     <meta name="twitter:site" content="@fotoleaf"> 
     <meta name="twitter:title" content="<?php echo $title; ?>"> 
     <meta name="twitter:description" content="<?php echo $metadescription; ?>" > 

     <!-- Twitter Summary card images must be at least 200x200px --> 
     <?php if ($adult == '1' && !$this->auth->loggedin()) : ?>         
      <meta name="twitter:image" content="<?php echo base_url(); ?>assets/images/fotoleaf-adult-image.jpg"> 
     <?php else : ?>         
      <meta name="twitter:image" content="<?php echo $image; ?>"> 
     <?php endif; ?> 

但是似乎除非我刷新頁面生效，它不會。所以我得到了未定義變量的所有PHP錯誤。

我正在加載它與所有其他視圖相同。

$this->load->view('v1/header_photo_view', $data); 
$this->load->view('v1/photo_view', $photodata); 
$this->load->view('v1/footer'); 

// SOCIAL AND SEO 
     foreach ($photodata['photographer'] as $photog) { 

      if ($photog['firstName'] != NULL) { 
       $photogName = $photog['firstName'] . ' ' . $photog['lastName']; 
      } else { 
       $photogName = $photog['username']; 
      } 
     } 

     if ($photodata['photos']['title'] == NULL) { 
       $data['title'] = "Untitled. by ". $photogName; 
     } else { 
      $data['title'] = $photodata['photos']['title']. " by ". $photogName; 
     } 

     $data['metadescription'] = $data['title'] . " was shared on fotoleaf. The place to share only your best photos."; 

     $data['imageurl']  = site_url('photo') . "/" . $photodata['photos']['id']; 
     $data['image']   = $photodata['photos']['upload_path'] . $photodata['photos']['file_name']; 
     $data['adult']   = $photodata['photos']['adult']; 

有沒有辦法強制它在刷新之前刷新？

我將$ data變量代碼移動到剛剛加載視圖上方，似乎已經修復了它。
