SWFUpload Code

First commit of the code cleanup branche

Ran through JSLint.
Still needs to have function names refactored (should be using camelCase instead of TitleCase unless it's a constructor)
Appearantly I was sleeping when I reviewed Joel's changes and misunderstood what he did. Sorry about that.

Ran code through JSLint and fixed many issues.
Fixed incorrect variable names in built in uploadError function.

Re-added declaration of image_name variable. It's fine to assign it in the default cause but by not included "var image_name" somewhere you've created a global variable rather than a locally scoped variable.

Merged all code from applicationdeom.net/js/handlers.js except thumbnail.php line 68
Fixed missing required param file_id in ToggleCancel function

Changed a comment from upload.php to upload.aspx - Line 65
Moved error.gif image_name to the top of function so upload error always has an image to display.

Updated to allow numbers in the post_params setting object. Checks are not made for the setPostParams and addFileParam methods. Objects are converted to strings before being posted.

Updated documentation.

Added sample file for disabling mod_security.

Moved the doctype after session_start

Fixed type-o in debug output.
Fixed spelling error in docs.

Added allowScriptAccess parameter to HTML embed & object so SWF files loaded from a different domain can still interface with JavaScript.
