Call function when ever eloquent model has CRUD operation.

[njdubois]

Hi!  

 

I'd like to create a function in an eloquent model that gets called whenever create() or save() is called on that model. This function updates an "updated_at" time stamp in a parent table.  

 

I don't even know what to search for in google that will lead me to a tutorial, or documentation explaining this.

 

For example:

 

I have 2 tables, Conferences (has "updated_at" timestamp field) and Maps (When ever a new map is saved, or existing updated I want to update the timestamp field "updated_at" in the Conferences table).

 

I know I could create a class with a function that does this and do a find for ->save() and after call my function.  

 

But why do that?  Shouldn't I be able to put a method in the Maps Model that, when CRUD happens, will automatically fire?

 

I guess it would look something like this:

 

    private function onCrud() {
        $confObj = Conference::where("id", "=", $session(['currentConfId']))->first();
        $confObj->updated_at = date("whatever format...");
        $confObj->save();
    }

How do I tell laravel/eloquent to fire this method when ever a save is called on the model?

 

Any direction with this is greatly appreciated!

 

Thanks,

Nick

I think i may have accidentally stumbled on a clue.

Oh my gosh!! I'm so sorry.  This is a cakePhp project.  Not a laravel project.  Wishful thinking...

Ok, I apologize a million times.  I'd delete this post completely if I could figure out how.

 

I am normally a laravel developer and most of our projects are laravel, except this one which is cakephp.

 

Regardless, I realize now that when I need to look into is event listeners.  I should be able to find more targeted documentation on this and maybe solve my own problem.

 

Thanks anyways!
