How do I do something when an entry is updated?

[backpack-operations]

So i have a backpack form, inside the Create and Update operation... i want when an entry is updated... to do something extra... like to set some attributes that don't have fields. How can I do that?

There are several ways to perform additional actions when an entry is updated in Backpack. Here are some options:

1. Override the update() method:
   You can override the update() method in your CrudController to add custom logic before or after the update operation. Here's an example:

   use \Backpack\CRUD\app\Http\Controllers\Operations\UpdateOperation { update as traitUpdate; }
   
   public function update()
   {
       // Do something before update
       $response = $this->traitUpdate();
       // Do something after update
       return $response;
   }

2. Use Laravel Events:
   You can use Laravel's built-in events in your setupUpdateOperation() method:

   public function setupUpdateOperation()
   {
       // ...
   
       YourModel::updating(function($entry) {
           $entry->last_edited_by = backpack_user()->id;
       });
   }

3. Use field events:
   You can define events directly on fields:

   CRUD::field('name')->on('updating', function ($entry) {
       $entry->last_edited_by = backpack_user()->id;
   });

4. Use the strippedRequest setting:
   You can modify the request before it's saved to the database:

   public function setupUpdateOperation()
   {
       CRUD::setOperationSetting('strippedRequest', function ($request) {
           $input = $request->only(CRUD::getAllFieldNames());
           $input['updated_by'] = backpack_user()->id;
           return $input;
       });
   }
