File upload fail on iphone safari ?

I think you have to rename the uploaded filename each time, otherwise you allways overwrite it with the new on. you can set this bei the file_name hash. for e.g.

Code:

$this->load->helper('inflector');
$file_name = underscore($_FILES['file_var_name']['name']);
$config['file_name'] = $file_name;

or this should also work with a custom name logic

$config['file_name'] = 'your_file_name';
