Sanitize Filename & Encrypt Name issue Codeigniter 3

[Aradea08]

Hello,

Thanks for your great work to this class.

I'm quite new in CI, and try to implement your class in my project.

but, i found some issues about your class in CI 3.

1. $this->clean_file_name already not work in CI 3, also will encounter error if i change it to $this->security->sanitize_filename / even $this->security->xss_clean.

For temporary solution i just let the code to be like this

//Sanitize the file name for security. $this->file_name = $this->file_name;

So far, it work, but i don't think it safe.

1. Encrypt Name also not work, it return nothing when i set it to TRUE.

here's is my code
// inisialisasi upload file $config = array( 'upload_path' => $dir, 'allowed_types' => 'jpeg|jpg|png', 'overwrite' => TRUE, 'encrypt_name' => TRUE, ); // load Upload library $this->upload->initialize($config); $this->load->library('upload', $config); $this->load->library('image_lib', $config);

but when i print_r it,

the result looks like this

`Array
(
[upload_data] => Array
(

        [1] => Array
            (
                [file_name] => mbuntu_(14).jpg

sanitize file name done...

is uset $CI =& get_istance on calling security->sanitize_filename() fiunction...thanks

As described by @Aradea08 there is a relatively easy solution to this. Open the MY_Upload.php file which you've stored inside your application/library folder. Go to line 381.

This is what it currently says:
$this->file_name = $this->clean_file_name($this->file_name);

Replace the whole line with:
$CI =& get_instance();
$this->file_name = $CI->security->sanitize_filename($this->file_name);

That's it!
