Detail page button calling Apex without new window

Question

I would like to add a custom detail page button to the order page which is only executing Apex. Without displaying a new window.

For the moment, my custom button is linked to a visualforce page which is calling the order standard controller and my custom extension. After getting the order record in the constructor of my custom extension, a public method is called by the visual force page via a command button. Finally, I make a redirection to the previous order page.

My goal is to be able to get the order record in the constructor of a class, make an update on it, then redirect directly to the order page without displaying any new window.

Thanks for your help.

You can accomplish it this way:

Page:

<apex:page standardcontroller="object__c" extension="mycontroller" action="updateMe">
    Maybe show some message here if the update fails  
</apex:page>

Controller

public with sharing mycontroller() {
   public object__c myobj {get; set;}

   public mycontroller(ApexPages.STandardController ctr){
      myobj = ctr.getRecord();
   }

   public pageReference updateMe() {
     //Do the update/DML here

     PageReference pageRef = new PageREference(myUrlGoesHere);
     pageRef.setRedirect(true);
     return pageRef;
   }
}
