Why is my upload path invalid? (Codeigniter-Library)

问题

I'm creating a library as part of a project and one of the methods is a wrapper for the upload helper.

The method:

 public function upload(){

    echo "Doing upload";

    $config['upload_path']= RESOURCE_PATH . "Downloads";
    $config['allowed_types']='pdf|doc';
    $config['max_size']='10000';
    //echo $config['upload_path'];

    $this->CI->load->library('upload',$config);

    if(!$this->CI->upload->do_upload()){
        echo "Couldn't do the upload";
        echo $this->CI->upload->display_errors();
        echo $config['upload_path'];
    }
    else{
        echo "Could do the upload";
    }
}

I've checked the directory permissions of the Downloads folder and that it exists but I'm getting the following error: "The upload path does not appear to be valid."

How do I resolve this issue?

EDIT:: I created a symlink so my directory strucutre really looks like:

 www -> /home/user/Dropbox/www/appname

Note about variables used:

$this->CI = &get_instance(); // Defined in custom library class 
define('RESOURCE_PATH', APPPATH . 'views/resources/'); // Defined in constants.php

回答1:

Figured out the idiotic problem.

I was autoloading the library and some how when I was trying to initialize the configuration by $this->load->library('upload', $config); it wouldn't do so.

Instead I put my config files in config/upload.php

The other method to do so would have been $this->upload->initialize($config);

See this answer.

Add this line

$this->CI->upload->initialize($config);

after

$this->CI->load->library('upload',$config);
