. # This file is useful for putting message box(es) on the screen. If you include # session_messages.php these messages can even persist accross http redirects # (such as you should do after receiving a POST. # # Just call message("message here") whenever you have something to report. # # # Once a template is loaded, call display_messages(). run.php will do that # automatically after your main function returns, so long as you require_once # this file. # # Just make sure your template has a section with a # ~value html~ tag in it. # # Simple example: # # #

~value html~

# # # Full-featured example: # # # #

~data html~
