Question

我确定这是一个愚蠢的问题，但由于某种原因它没有显示错误。它只显示一个白色的屏幕。

应该在空表单提交时执行此操作： http://kansasoutlawwrestling.com/peach/Template/login.html

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Usermanagement extends CI_Controller { 

public function index()
{
    //Config Defaults Start
    $msgBoxMsgs = array();//msgType = dl, info, warn, note, msg
    $cssPageAddons = '';//If you have extra CSS for this view append it here
    $jsPageAddons = '';//If you have extra JS for this view append it here
    $metaAddons = '';//Sometimes there is a need for additional Meta Data such in the case of Facebook addon's
    $siteTitle = '';//alter only if you need something other than the default for this view.
    //Config Defaults Start


    //examples of how to use the message box system (css not included).

使用我的模板系统，任何人都可以看到我需要做些什么来纠正他的问题？

Answer 1

你打电话给会议的自动加载吗？它看起来像你的代码没有__construct()它看起来像你使用另一个库或帮助器，只是确保你必须加载它们

Answer 2

尝试启用错误报告。在脚本的顶部添加这行代码

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

如果仍然无效，请尝试在脚本的不同部分回显一些内容，以查看失败的位置。您在脚本中的某处有解析错误或致命错误。

你在任何地方使用输出缓冲吗？

我早些时候在AIM上与你谈过.. 您在页面上收到的错误。

“消息：无法修改标题信息 - 已经发送的标题（输出从/home/xtremer/public_html/kowmanager/application/controllers/usermanagement.php:3开始）”

显示具有CI的会话当前未运行。或者您在召开会议之前向浏览器输出内容。了解您的CI安装。我会说你的问题部分是缺少缺失的_construct。导致CI安装自动加载会话功能。当你想使用像

这样的东西时，这是必需的

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

将构造函数重新放入，就像使用其他控制器一样，然后再次尝试加载页面，看看是否没有修复它。

表单验证为空
