| Drag & drop files & folders onto the webpage to have the files upload.<br><br> | |
| Need to improve this to recognise files in folders, subfolders etc.<br><br> | |
| Ideas? Please tweet me: <a href="https://twitter.com/#!/mattpass" target="_blank">@mattpass</a><br><br> | |
| (Note: Files & folders not actually saved on the webspace, PHP only reports what's been uploaded).<br><br> | |
| <form action="upload.php" target="saveFrame" id="fileForm" method="POST"> | |
| <input type="text" id="numFiles" name="numFiles" size="3"> = no of files<br> | |

You can drag & drop files & folders onto the webpage to have them posted to the PHP page in the iFrame. However, this only works 1 level deep and doesn't cover whats inside folders. Any ideas on how I can make it also cover files & folders within folders?
