CodeIgniter-删除文件，出现路径问题 [英] CodeIgniter - Delete file, pathing issue

问题描述

我的根目录中有3个文件夹：应用程序，系统和上载。在application / controllers / mycontroller.php中，我有这行代码。

I have 3 folders in my root, "application", "system", and "uploads". In application/controllers/mycontroller.php I have this line of code.

delete_files("../../uploads/$file_name");

文件没有被删除，我尝试了许多路径选项，如../和。 。/../../ 有任何想法吗？谢谢。

The file does not get deleted and I have tried a number of pathing options like ../ and ../../../ any ideas? Thanks.

推荐答案

$ file_name 是一个变量。您应该将其连接到自己的字符串以执行该功能：

$file_name is a variable. You should concatenate it to your own string in order to execute the function:

delete_files("../../uploads/" . $file_name);

编辑：

请确保以下句子：

echo base_url("uploads/" . $file_name);

正在回显有效路径。如果答案为是，请尝试以下操作：

Is echoing a valid path. If the answer is YES, try this:

$this->load->helper("url");
delete_files(base_url("uploads/" . $file_name));

假设您的上载文件夹位于根目录中。

Supposing that your "uploads" folder is in your root directory.

编辑2：

使用 unlink 函数：

$this->load->helper("url");
unlink(base_url("uploads/" . $file_name));
