Laravel Backpack - Set extra attributes before page save

Question

In my PageTemplates.php I have a field like this:

$this->crud->addField([
    'name' => 'adres',
    'label' => 'Adres',
    'type' => 'address',
    'fake' => true,
]);

Now I would like to save also the latitude and longitude of the address they give in (if it can be found). I've copied the PageCrudController and changed the config in config/backpack/pagemanager.php to:

return [
    'admin_controller_class' => 'App\Http\Controllers\Admin\PageCrudController',
    'page_model_class'       => 'App\Models\Page',
];

In my store function I have:

public function store(StoreRequest $request)
{
    $address = $request->request->get('adres');
    $addressObj = app('geocoder')->geocode($address)->get()->first();

    if($addressObj)
    {

    }

    $this->addDefaultPageFields(\Request::input('template'));
    $this->useTemplate(\Request::input('template'));

    return parent::storeCrud();
}

But what do I place in the if statement? How can I add (= set) an extra field to the extras field in my database?

Try like this `if($addressObj) { $request->latitude = '23.5'; $request->latitude = '40.5'; }` — Niklesh Raut, Nov 18 '17 at 11:37
@user2486, tried it, but doesn't work. There not saved. This also doesn't work with other fields. — nielsv, Nov 18 '17 at 12:04
Where is `storeCrud` this function written ? is it also in `$this->storeCrud` or only in `parent::storeCrud` ? — Niklesh Raut, Nov 18 '17 at 12:05
then you can try only `$this->storeCrud` no need to call as `parent::` — Niklesh Raut, Nov 18 '17 at 12:30

In backpack 4.1, I solved my issue by the following way : Override the store method in my controller, set my extra field in request and then call the backpack store method Don't forget to add include backpack trait Hope the solution will help someone

use \Backpack\CRUD\app\Http\Controllers\Operations\CreateOperation { store as traitStore; }

public function store()
{
    $this->crud->setOperationSetting('saveAllInputsExcept', ['save_action']);
    $this->crud->getRequest()->request->add(['updated_by' => backpack_user()->id]);     
        
    return $this->traitStore();
}

Fixed it by doing the following:

Add latitude and longitude as hidden fields:

$this->crud->addField([
    'name' => 'latitude',
    'type' => 'hidden',
    'fake' => true,
]);

$this->crud->addField([
    'name' => 'longitude',
    'type' => 'hidden',
    'fake' => true,
]);

Set attributes by doing the following:

if($addressObj)
    {
        $request['latitude'] = $addressObj->getCoordinates()->getLatitude();
        $request['longitude'] = $addressObj->getCoordinates()->getLongitude();
    }
}

Change parent::updateCrud to parent::updateCrud($request);.

For people still looking at this issue, I'd recommend you follow the advice in the note under the Callbacks section of Laravel Backpack's docs if you don't just want to observe changes made from the Backpack admin panel, you just need to create an Observable.

To do this you can do the following:

Create an Observer class: php artisan make:observer YourObserver --model=YourModel
Add your code to the generated event methods you wish to observe.
Register the Observer by calling the observe method on the model you wish to observe in your EventServiceProvider's boot method like so:
```
public function boot()
{
    YourModel::observe(YourObserver::class);
}
```

Or equally you can register the Observer to the $observers property of your applications' EventServiceProvider class:

protected $observers = [
    YourModel::class => [YourObserver::class],
];
