Help With Coding Challenge - Observer/Notfiers in admin?

[Dayo]

I realise I can but I am reluctant to edit any of the core files.

Thanks for your well.

Eventually, you will have to anyway. For example, files inside includes/modules/pages have not over-ride.

For my own use, I have no hesitation and reluctance is for stuff I am thinking might be put up for general download.

Anyway, I will be looking and the notifiers to understand how they work.

Thanks for the pointer

Hello.

This is a follow up to this thread http://www.zen-cart.com/forum/showthread.php?t=88191

I decided to implement a custom notifier but no joy as the event does not seem to trigger my code.

The aim is to edit the DB entries after a user clicks "update" in a payment module admin.

What I have done so far is

1) In module.php, I added

$zco_notifier->notify('NOTIFY_MODULE_AFTER_ADMIN_SAVE_DB_UPDATE'); 

after the while loop that includes....

$db->Execute("update " . TABLE_CONFIGURATION . "
set configuration_value = '" . $value . "'
where configuration_key = '" . $key . "'");

in the "save" switch section. This should call the notifier if I understand the process correctly.

2) in includes/autoloaders, I created a file called config.mynewclass.php with the following code...

<?php

$autoLoadConfig[180][] = array('autoType'=>'class',
                              'loadFile'=>'observers/class.mynewclass.php');
$autoLoadConfig[180][] = array('autoType'=>'classInstantiate',
                              'className'=>'mynewclass',
                              'objectName'=>'mynewclass');
?>

QUERY >> Not sure which breakpoint to use as the wiki is not clear on this. Any tips?

3) In classes/observers, I created a file called class.mynewclass.php with the following code...

<?php
 class mynewclass extends base {
   function mynewclass() {
       global $zco_notifier;
    $zco_notifier->attach($this, array('NOTIFY_MODULE_AFTER_ADMIN_SAVE_DB_UPDATE'));
   }
   
   function update(&$callingClass, $notifier, $paramsArray) {
    
    My code.... 
       
   }
   
 }
 ?>

QUERY >> Can anyone spot where I may have goofed?

Thanks for your help

As far as I am aware the notifier system is for the catalog side of Zen Cart. I don't think it works on the admin side. Could be wrong though.

That's probably the reason. All clicks into place.

I wonder whether it is possible to trick it to work.

[Dayo]

After checking, I am not so sure it doesn't work in Admin as config.core.php in admin/includes instantiates zco_notifier.

I will try to place my files in admin/includes/auto_loaders and admin/includes/classes/observers (after creating the observers folder) and see what happens.

[Dayo]

OK I can see there isn't the equivalent of class.base.php in admin which contains all the notifier functions.

Wonder why zco_notifier is instantiated though.

Perhaps one of the gurus can give a definitive answer on whether this is a goer or not.

[DrByte]

Support for observer/notifier functionality in the admin is limited.

Additionally, the admin shares many catalog-side functions/classes files, including class.base.php etc.

BTW ... your threads have been merged, due to similarities and same end goal.

OK thanks

i found a way round my problem by restructuring what i am doing.
