New Dynamic Element: WOFileUpload

 A WOFileUpload element displays a form element in which a client browser can specify a file to be uploaded to the server. It corresponds to the HTML: <INPUT type=file>.

Note: WOFileUpload elements inside of a WOForm require that the WOForm have the attribute's encoding type set as follows:

enctype = "multipart/form-data"
For further information on the file upload specification, see RFC1867: http://www.w3.org/RT/REC-html32.html#rfc1867.

WOFileUpload has the following attributes:
WOFileUpload
Attribute Description
filePath The full file path and name of the file uploaded is sent by the browser and returned as a string to the variable or method bound to this attribute.
data The file that is uploaded will be returned as an NSData object to the variable or method bound to this attribute.

If you want to process a file upload in a direct action, use WORequest's formValueForKey: method to get the contents of the file that has been uploaded. This method previously returned an NSString. It is now declared as follows:

- (id)formValueForKey:(NSString *)aKey
or, in Java,

public java.lang.Object formValueForKey(java.lang.String aKey)
