表單驗證空

Question

我敢肯定這是一個愚蠢的問題，但由於某種原因，它沒有顯示錯誤。它只顯示一個白色屏幕。

應該是一個空的表單提交這樣做： http://kansasoutlawwrestling.com/peach/Template/login.html

隨着我的模板系統，任何人看到我會做糾正自己的問題？

Answer 1

我剛纔在AIM上與你談過.. 你在頁面上的錯誤。

「消息：無法修改標題信息 - 頭已經發出（輸出開始/home/xtremer/public_html/kowmanager/application/controllers/usermanagement.php:3）」

節目或者與CI會議AREN目前正在運行。或者在您打電話前向瀏覽器輸出內容。親自了解您的CI安裝。我會說你的問題部分是由於缺少_construct。導致您的CI安裝自動加載會話功能。當你想使用類似這是必需的，

$this->session->userdata('is_logged_in') 

把構造函數早在像您有其他控制器，並再次嘗試加載頁面，看看那不解決它。遇到

Answer 2

嘗試打開錯誤報告。在你的腳本的頂部添加此行代碼

<?php error_reporting(E_ALL ^E_NOTICE); ?> 

如果仍然不行嘗試在腳本的不同部分呼應的東西，看看它失敗。您的腳本中某處出現解析錯誤或致命錯誤。

你是否在任何地方使用輸出緩衝？

Answer 3

你有沒有自動加載會話？它看起來像你的代碼沒有__construct()它看起來像你使用另一個庫或幫手，只是確保你必須加載它們
