ad_build_mime_message (public)

 ad_build_mime_message text_body html_body [ charset ]

Defined in packages/acs-tcl/tcl/html-email-procs.tcl

Composes multipart/alternative email containing plain text and html versions of the message, parses out the headers we need, constructs an array and returns it to the caller. This proc is based on ad_html_sendmail, written by Doug Harris at the World Bank.

Parameters:
text_body (required)
html_body (required)
charset (optional, defaults to "UTF-8")
Returns:
ns_set containing MIME-Version, Content-ID, Content-Type, and body
