CodeIgniter不加载页面 [英] CodeIgniter not loading pages

问题描述

我有一个web应用程序使用codeigniter开发，它的工作正常在我以前的服务器，现在我改变了我的服务器，当我试图运行Web应用程序只有一个空白屏幕。

I have a web application developed using codeigniter and it worked fine in my previous server now I changed my server and when I am trying to run the web application there is nothing but a blank screen.

当我尝试打开现有链接时 http://mydomain.com/MyProject1/
它是一个有效的链接，但它显示一个空白页。

When I am trying to open the existing link http://mydomain.com/MyProject1/ It's a valid link but its showing me a blank page.

当我试图打开另一个现有的链接mydomain.com/MyProject1/login/
这也是一个有效的链接，但它只显示一个空白页。

When I am trying to open another existing link mydomain.com/MyProject1/login/ This too a valid link but its displaying just a blank page.

只是为一个测试，我尝试了一些错误的链接 http://mydomain.com/MyProject1/test
显示404错误。

Just for a test I tried some wrong link http://mydomain.com/MyProject1/test It's showing 404 error.

所以，一定是代码运行正常，但页面不显示。

So, must be the code is running fine but pages are not being displayed. It's only showing blank page.

如何解决此问题？

推荐答案

确定，在index.php（它在根中）显示错误，并将此条件更改为：

Ok, turn displaying error in index.php (it's in the root) and change this if condition to something like:

if (defined('ENVIRONMENT'))
{
    switch (ENVIRONMENT)
    {
        case 'development':
            error_reporting(E_ALL ^ E_NOTICE);
        break;

        case 'testing':
        case 'production':
            // error_reporting(0);
            error_reporting(E_ALL ^ E_NOTICE);
        break;

        default:
            exit('The application environment is not set correctly.');
    }
}

然后出现错误。

Btw。尝试设置正确的htaccess路径到您的应用程序，如果你使用它。如果在您的localhost它是：

Btw. try to set the correct htaccess path to your app if you are using it e.g. if on your localhost it was:

RewriteEngine On

RewriteBase /projects/mywebsite/

在服务器上将其更改为：

change it on server to:

RewriteEngine On

RewriteBase /

不使用子域等。

Btw。如果您遇到类似于已发送的标头的错误，您需要将文件另存为无BOM的utf-8，而不是utf-8 。或者，文件开头可能有一些字符，您需要在文本编辑器中将其删除。

Btw. if you get an error like headers already sent or something like that, you will need to save your files as "utf-8 without BOM" instead just "utf-8". Or there might be some characters on the beginning of the file, which you need to delete in your text editor.

检查您正在使用的文件，例如语言文件，视图，控制器等，并检查它们是如何编码的。如果他们是utf-8更改编码为utf-8没有BOM。它可以在几乎每个文本编辑器，如记事本++或Sublime。然后将这些文件重新上传到您的服务器。

Check the files you are working with e.g. language files, views, controllers etc. and check them how are they encoded. If they are utf-8 change encoding to utf-8 without BOM. It can be done in almost every text editor like Notepad++ or Sublime. Then reupload these files to your server.
