Best way to call a custom function on event 'on_page_add' and 'on_page_delete'

Permalink
Hello All,
I am working on refresh cache for auto and page list when a new page add or delete.
I have on custom function that i want to call when these event get execute.

My call of event is like :
Events::addListener('on_page_delete', array($this, 'CacheBlockClearOn'));
Events::addListener('on_page_add', array($this, 'CacheBlockClearOn'));


I have add this in 'public function on_start()' in core block controller file. But it not working with full page cache enabled.

After that i have add this in core 'Package' class in src\package\package.php , this work with the event 
Events::addListener('on_page_version_approve', array($this, 'CacheBlockClearOn'));


this will work but the problem is 'on_page_add' and 'on_page_delete' events not get execute so unable to refresh cache.

Can anybody tell me the better solution to add this event so this can execute every time page add or delete?

Or provide me better solution to do same.

Thanks in advance.

You can put your on_start handler in a package controller, then set up all the other event handlers from there.

Hello @johntheFish,

I have tried with this file core 'Package' class in src\package\package.php, but here only ''on_page_version_approve'' event works.
So do you mean this file?
Or i have to create new package and in that i have setup all my event handlers?

John is suggesting that you include this handling code in a new package.

Create a package called auto_cache and put the following code in controller.php :
<?php
namespace Concrete\Package\AutoCache;
use Package;
use Events;
class Controller extends Package {
    protected $pkgHandle = 'auto_cache';
    protected $appVersionRequired = '5.7.3';
    protected $pkgVersion = '0.9';
    public function getPackageDescription() {
        return t("A package to automatically trigger cache flushes");
    }
    public function getPackageName() {
        return t("Auto Cache");
    }
    public function install() {

No c5 events are run when the full page cache is enabled.

If you can't turn full page caching off, the only thing I can suggest is the trigger of a cache flush by way of an automated job and a cron job.
