You can use metadata in the following Application templates: upload.html, enter.html, login.html or fbprofile.html.
An example is provided below.
The format used is meta[user][metaname]
In Media Factory, for the meta data form to be called “agent”, the format of the name is the following: meta[user][agent]
To ensure that the metadata is uploaded with the media, add it to the swf uploader's params as follows:
if ( $('#agentMeta').length > 0 ) { swfu.addPostParam('meta[user][agent]', $('#agentMeta').val()); }
Where 'agentMeta' is the id for the input text field containing the metadata.
