/* This, as you have probably guessed, is the crux on which SMF functions.
|
||
|
|
Everything should start here, so all the setup and security is done
|
||
|
|
properly. The most interesting part of this file is the action array in
|
||
|
|
the smf_main() function. It is formatted as so:
|
||
|
|
|
||
|
|
'action-in-url' => array('Source-File.php', 'FunctionToCall'),
|
||
|
|
|
||
|
|
Then, you can access the FunctionToCall() function from Source-File.php
|
||
|
|
with the URL index.php?action=action-in-url. Relatively simple, no?
