You can limit the number of files before submitting by adding a onchange event to the input element. As soon as it's triggered you check the number of files. Here is a simple example for a 2 file limit:

<input type="file" onchange="if(parseInt($(this).get(0).files.length)>2) 
                               alert('You can only upload a maximum of 2 files'); 
                             else alert('You are within the limit');" multiple/>
