Override core functionality

Override core functionality

Hi there,

Is there a way where I could re define/declare the core modules of moodle like message_send() or email_to_user() functions without directly editing the core files. 

Purpose is that, I would like to add some extra functionalities to happen along with the actual functionality when ever these functions are called. I could edit the core function, but, during upgrade, I might have to re-edit. 

I could add custom function, but, this functions needs to be called where ever the message_send() or email_to_user() functions are called. We have them in many places this would again consume a lot of time and resource to identify the places and add this.

Any suggestion on how this can be achieved.

Thanks in advance

It would probably need to be an output renderer override in your theme. 

I recently wrote up a post for my own reference about overriding a different core function with links to the relevant Moodle documentation that you might find useful https://www.dgmyspace.dumgal.ac.uk/eportfolio/rumbler/2021/08/14/moodle-theme-building-role-descriptor/

You'll need to figure out where the function is being defined and what the class you need to extend is called. My guess would be somewhere either in /lib or /mod although having done a quick search it might be /message/renderer.php 

I hope that at least gives some starting points. 

I know it doesn't entirely answer the question!
