Generate a Form element with multipart encoding as a String.

Multipart encoding is used for forms that include file uploads.

action is the action to perform. enctype is the encoding type, which defaults to “multipart/form-data”.

Alternatively, the attributes can be specified as a hash.

Example

multipart_form{ "string" }
  # <FORM METHOD="post" ENCTYPE="multipart/form-data">string</FORM>

multipart_form("url") { "string" }
  # <FORM METHOD="post" ACTION="url" ENCTYPE="multipart/form-data">string</FORM>
