Hey i would like to do this : http://hosting.mrkrabz.net/

 

I've got the base down you can upload single files, But how would i make it so when you click a button it adds a new field for a file to be uploaded and when you click upload it uploads the files in the box's and not just 1 of them all the ones you have put in the field's. ??

you would want to make an html array, like

<input type="file" name="files[]" />
<input type="file" name="files[]" />

 

and in PHP, you would upload them in a loop, like so

for ($i = 0; $i < count($_FILES['files']['name']; $i++){
//i access each individual files stuff like so
$name = $_FILES['files']['name'][$i];
$size = $_FILES['files']['size'][$i];
//upload it now

 

for the button click, you will need javascript. You could surround the input file field with a div, and use javascript, and the innerHTML attribute of the div (gotten by document.getElementById()) to add another file field
