WOFileUpload

Element Description

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>.

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.

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 is declared as follows:

- (id)formValueForKey:(NSString *)aKey

or, in Java,

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