Joomla 4 - triggering an event on order status change

[webgobe]

For Joomla 3 I used plgVmCouponUpdateOrderStatus, and worked perfectly.
On Joomla 4 the events whose name does not start with "on" no longer work. I tried to find in VM 4.0.12 I could use instead to catch the order status change event (I need that to trigger actions in a custom built component) but no luck so far. Any hint, idea or solution is highly appreciated!

plgVmOnUpdateOrderPayment  ?

[webgobe]

Thanks, will try your tip obviously, the problem seemingly is not the triggering event - the one I used is still there in the code of VM - but this:

"On Joomla 4 the events whose name does not start with "on" no longer work."

I did not marked it correctly to be obvious, but the sentence is from this page: https://docs.joomla.org/Potential_backward_compatibility_issues_in_Joomla_4#Plugins_.28Events.29

Yup, as I suspected. Nothing. Not even an error message. Anyways, the client needs the event to be triggered when the order is confirmed by shop admin

Works fine for me

Anyways, the client needs the event to be triggered when the order is confirmed by shop admin

That is what I use it for

Code Select Expand

function plgVmOnUpdateOrderPayment ($data,$old_order_status) {
                    $status = $this->params->get('status', 'C');
                    $status_array = explode(',',$status);
      if(in_array($data->order_status, $status_array)){
                               // do something
                           }
                   }

I have this:

Code Select Expand


function plgVmOnUpdateOrderPayment ($data,$old_order_status){
Factory::getApplication()->enqueueMessage('Royalty check  on UpdateOrderStatus', 'message');
vmdebug('Royalty check  on UpdateOrderStatus '.$data->order_status);
// .... and some other code
}

I get nothing, The plugin isn't triggered. The code works on J3...

On Joomla 4/VM 4.0.12??

[GJC Web Design]

yep -- exactly the code above in a VMCustom plugin triggered by the order going to Confirmed

[webgobe]

Can you please share the full plugin code??? I am doing something wrong somewhere, and can't find out what...

[GJC Web Design]

I have pasted the relevant code here.. the rest has nothing to do with the triggering
