Upload library question - El Forum - 05-07-2009
[eluser]i_am_using_ci[/eluser]
Hi, I am using Upload class in my applicaiton and got interesting situation:
I want all files being uploaded to my server has encrypted names, so I am doing:
Code:
...
$config['encrypt_name'] = true;
$this->load->library('upload', $config);
...But file names were not modified, I've started making some checks, my config was correct and option was passed correctly, but there is code in Libraries/Upload.php:
Code:
if ($this->overwrite == FALSE)
{
$this->file_name = $this->set_filename($this->upload_path, $this->file_name);
if ($this->file_name === FALSE)
{
return FALSE;
}
}It says that if I set $config['overwrite'] to 'false' it will make names encrypted, otherwise none...
I can't understand that logic, where is connection between 'overwrite' and 'encrypt_name', who could explain why it's so?

Where does it say that if you set overwrite to false it will make file names encrypted?
According to the user guide, the overwrite function does the following:
Quote:If set to true, if a file with the same name as the one you are uploading exists, it will be overwritten. If set to false, a number will be appended to the filename if another with the same name exists.
There is a slight possibility that whenever you encrypt a file, this new encrypted name also matches a previously encrypted. By setting overwrite to false it will rewrite the old file and by setting it to true it won't rewrite the old file, it will add a number to the filename so it isn't overwritten.
Hope that helps.

See 2nd code paste, it's part of CI Upload library, there are encrypt_name possible if only overwrite false...There is no other encrypt_name block, only that I pasted.
