File size checking for uploaded files
A new javascript file, file_upload.js, handles client side file size checking.
The function, checkUploadSize(), accepts an html file input element and a maximum
file size (in bytes) as input. If the size of the file to be uploaded exceeds the
size allowed, a message is displayed the the element is cleared. Server side
checking is still used if it passes this test.
Loading file_upload.js adds event handlers to file input elements with
class="flUpload".
<input type="file" class="flUpload" />
It also looks for a hidden element with id="free_space" that contains the maximum
upload size.
<input type="hidden" id="free_space" value="$free_space" />
The free space is usually calculated by subtracting a user's disk usage from their
quota allowance. In some cases it is a fixed value.
I have implemented this for every upload instance I could find. These include:
* Message attachments
* Authoring space
* Portfolio
* Course editor
* Essay response problems
* Helpdesk request forms
* RSS feed uploads
