2.                 <div class="row">
3.                     <div class="file-field input-field col s6">
4.                         <div class="btn">
5.                             <span>MANILA</span>
6.                             <input type="file" id="mnl_process">
7.                         </div>
8.                         <div class="file-path-wrapper">
9.                             <input class="file-path validate" type="text">
10.                         </div>
11.                     </div>
12.                     <div class="file-field input-field col s6">
13.                         <div class="btn">
14.                             <span>IN-COUNTRY</span>
15.                             <input type="file" id="inc_process">
16.                         </div>
17.                         <div class="file-path-wrapper">
18.                             <input class="file-path validate" type="text">
19.                         </div>
20.                     </div>
21.                 </div>

So I need 4 of that code all I have to do is change the id from mnl_x to inc_x where x is the name of the category. In this case the category name is process.

I know AJAX, jQuery and PHP but I haven't tried to do uploads.

How should I approach this properly? So I can attach it under one button.

Here is my jQuery idea:

2.         $("#upload_values").click(function() {
3.             $("input[type=file]").each(function(){
4.                 //I'll insert ajax post here but I don't know how upload
5.             }); 
6.       });
