The Notes API
From OpenEMR Project Wiki
Using the Notes API
The Notes API is available in OpenEMR by including the following line in your code:
require_once("$srcdir/pnotes.inc");
Thos loads up all of the functions for dealing with notes.
Once that is done, it is important to use the appropriate ACL checks to ensure that users who are viewing/updating/deleting notes are authorized to do so.
Once pnotes.inc is included, the following functions are available:
addPnote
deletePnote
getPnoteById
getPnotesByUser
updatePnote
updatePnoteMessageStatus
Dependencies
The Notes API uses the database table 'pnotes' to store its data.
