You could of course create pdf invoices on-the-fly. But if you wish to store the invoices on your file system this is what you could do:
1. Store pdf outside of webroot so it cannot be accessed.
2. Create controller that checks for login and forces download of the file.
Controller function 'open'
Code:
function open ()
{
// Check if user is logged in
$this->load->library('yourauthlibrary');
if ($this->yourauthlibrary->checkAuth()) {
redirect('login', 'refresh');
}
// Retrieve invoice filename, file ID is passed in URI
// The model needs to return false if this is another user's invoice!
$this->load->model('yourinvoicesmodel');
$filename = $this->yourinvoicesmodel->fetchInvoice($this->uri->segment(3));
// No data found, show error
if (! $filename) {
show_error('The invoice you were looking for could not be found.');
}
// Set filepath
$filepath = '/PATH/TO/INVOICES/FOLDER/' . $filename;
// Force download
if (file_exists($filepath)) {
// Use download helper to force download
$this->load->helper('download');
// Read file as string
$data = file_get_contents($filepath);
// Force download
force_download($filename, $data);
}
else {
// File does not exist
show_error('The invoice you were looking for does not exist.');
}
}
