从CI中的子目录外部定位文件 [英] locate file from outside a sub-directory in CI

问题描述

我有两个codeigniter安装在我的CI项目。

I have two codeigniter installs in my CI project. But in my second codeigniter install I am having trouble calling a path from outside of the install folder.

项目布局：

application folder
download folder
image folder
install folder "This contains own index.php and application folder"
system folder
index.php "main index.php"

我有麻烦从外面调用路径是安装文件夹。我需要能够找到第一个应用程序文件夹。

The area I am having trouble call path from outside is the install folder. I need to be able to locate the first application folder.

有问题的例子。

此代码在安装应用程序文件夹中查找。

<tr>
<td><?php echo FCPATH . 'application/config/database.php'; ?></td>
<td class="align_right"><?php echo is_writable(FCPATH . 'application/config/database.php') ? '<span class="text-success">Writable</span>' : '<span class="text-danger">Unwritable</span>'; ?></td>
</tr>
</tbody>
</table>

并显示 C：\xampp\htdocs\codeigniter\install\ application / config / database.php

但需要它能够获取主目录应用程序文件夹。所以看起来像这样 C：\xampp\htdocs\codeigniter\application / config / database.php

But need it to be able to pick up the main directory applications folder. So would look like this C:\xampp\htdocs\codeigniter\application/config/database.php

我不想在安装index.php中触摸任何内容

APPPATH无效，因为安装文件夹有自己的应用程序文件夹需要获取apppath从外部安装文件夹。

APPPATH Does not work because the install folder has its own application folder Need to get the apppath from outside install folder.

推荐答案

现在工作方式

<tr> <td><?php echo dirname(FCPATH) . '/application/config/config.php'; ?></td> <td class="align_right"><?php echo is_writable(dirname(FCPATH) . '/application/config/config.php') ? '<span class="text-success">Writable</span>' : '<span class="text-danger">Unwritable</span>'; ?></td> </tr>`
