如何使用codeigniter在缓存文件夹中创建子文件夹? [英] How To Create sub folder in cache Folder using codeigniter?

问题描述

class Caching extends CI_Controller { 

public function index() 
{ 
   $this->load->view('employee/index'); 
   $this->output->cache(15);
} 

} 

我能够在cache文件夹中为index.php创建缓存，但是我想在cache/employee/cache文件下创建一个文件夹

I am able to create cache for index.php in cache folder, but I want to create a folder under cache/employee/cache file

根据视图正在调用的文件夹动态创建文件夹

creating Folder Dynamically based on which folder the view is calling

推荐答案

我想您想在缓存文件夹中创建子文件夹.因此，您可以修改system/helpers/file_helper.php

I suppose you want to create subfolders in cache folder. So, you can modify system/helpers/file_helper.php

函数write_file()应该像这样

Function write_file() should be like this

function write_file($path, $data, $mode = FOPEN_WRITE_CREATE_DESTRUCTIVE)
{
    // Modifications here
    # Usage:
    # $this->cache->save('user/favourites/page1', $favourites);
    # Will create folder 'user/favourites' at cache folder and file 'page1' with data
    if (strpos($path, '/') !== false) {
        $folders = explode('/', $path);
        unset($folders[count($folders) - 1]);
        $dir = implode('/', $folders);
        mkdir($dir, 0744, TRUE);
    }
    // End of modifications

    if ( ! $fp = @fopen($path, $mode))
    {
        return FALSE;
    }

    flock($fp, LOCK_EX);
    fwrite($fp, $data);
    flock($fp, LOCK_UN);
    fclose($fp);

    return TRUE;
}

或者您可以创建文件my_file_helper.php来扩展"系统帮助程序并覆盖此功能.这是更好的解决方案.

Or you can create file my_file_helper.php to "extend" system helper and override this function. This is much better solution.
