multiple files upload not working?

Make sure your form has this opening tag:

PHP Code:

<form method="post" action="some_action" enctype="multipart/form-data" /> 


Put this code at the top of your lets_upload method:

PHP Code:

echo '<pre>';
print_r($_FILES);
echo '</pre>';
die(); 


This will show you the file data from your view.
Once you get this part working, you can remove this piece of code.
