Upload File Bug

[eluser]Josepzin[/eluser]
I quoted my very, very simple solution, really, is simple and easy, without make changes to the /system code.

Is necessary only one line of code before upload the file, it search the extension of the selected file to upload in the allowed types:

Code:

$config['allowed_types'] = substr(
    $allowed_types,
    strpos($allowed_types, substr($_FILES['userfile']['name'], -3)), 3);

Example:

Code:

$allowed_types = 'pdf|doc|jpg|zip|png|gif'; // <--- your allowed types

// This is my fix
$config['allowed_types'] = substr($allowed_types, strpos($allowed_types, substr($_FILES['userfile']['name'], -3)), 3);

// load library and config params
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{...

The result of this code is:

With $_FILES['userfile']['name'] = 'document.pdf';
$config['allowed_types'] = 'pdf';
Ok, upload it!

Or:

With $_FILES['userfile']['name'] = 'image.jpg';
$config['allowed_types'] = 'jpg';
Ok, upload it!

Another with incorrect type:

With $_FILES['userfile']['name'] = 'terrible_mortal_virus.exe';
$config['allowed_types'] = 'pdf'; // <--- The first extension of $allowed_types
Error, type not allowed.
