You can attach as many files as you like, just cascade them.
$this->email->attach($full_path_and_name);
$this->email->attach($full_path_and_name);
In your case if your using the FILES array you would need to attach them
inside of a for loop, getting the file path and name into a string variable.
What did you Try? What did you Get? What did you Expect?
