Answer 1

Name the inputs with square brackets at the end of their name. If there is no value inside the brackets, they will be put sequentially into an array. If there is a value, that will be used as the key in the array:

HTML:

<input type="hidden" name="inp[]" value="a" />
<input type="hidden" name="inp[]" value="b" />
<input type="hidden" name="inp[]" value="c" />
<input type="hidden" name="inp[foo]" value="bar" />

PHP:

print_r($_POST);
/* 
array(
    0 => 'a',
    1 => 'b',
    2 => 'c',
    'foo' => 'bar'
)
*/

The same should apply to the $_FILES array.

PHP has a max_upload_size and max_post_size If your upload post size exceeds these then uploads often fail. Make sure you have these set real high, I usually set 200M+

use phpinfo() to get what these values are set too

A better option is to have your script upload each file one at a time in the background
