​
Customizing data before saving

Sometimes, you may wish to modify form data before it is finally saved to the database. To do this, you may define a mutateFormDataBeforeCreate() method on the Create page class, which accepts the $data as an array, and returns the modified version: 
protected function mutateFormDataBeforeCreate(array $data): array
{
    $data['user_id'] = auth()->id();

    return $data;
}
Alternatively, if you’re creating records in a modal action: 
use Filament\Pages\Actions\CreateAction;

CreateAction::make()
    ->mutateFormDataUsing(function (array $data): array {
        $data['user_id'] = auth()->id();

        return $data;
    })

​
Customizing the creation process

You can tweak how the record is created using the handleRecordCreation() method on the Create page class: 
use Illuminate\Database\Eloquent\Model;

protected function handleRecordCreation(array $data): Model
{
    return static::getModel()::create($data);
}
Alternatively, if you’re creating records in a modal action: 
use Filament\Pages\Actions\CreateAction;
use Illuminate\Database\Eloquent\Model;

CreateAction::make()
    ->using(function (array $data): Model {
        return static::getModel()::create($data);
    })

​
Customizing form redirects

By default, after saving the form, the user will be redirected to the Edit page of the resource, or the View page if it is present. You may set up a custom redirect when the form is saved by overriding the getRedirectUrl() method on the Create page class. For example, the form can redirect back to the List page: 
protected function getRedirectUrl(): string
{
    return $this->getResource()::getUrl('index');
}
If you wish to be redirected to the previous page, else the index page: 
protected function getRedirectUrl(): string
{
    return $this->previousUrl ?? $this->getResource()::getUrl('index');
}

​
Customizing the save notification

When the record is successfully created, a notification is dispatched to the user, which indicates the success of their action. To customize the title of this notification, define a getCreatedNotificationTitle() method on the create page class: 
protected function getCreatedNotificationTitle(): ?string
{
    return 'User registered';
}
Alternatively, if you’re creating records in a modal action: 
use Filament\Pages\Actions\CreateAction;

CreateAction::make()
    ->successNotificationTitle('User registered')
You may customize the entire notification by overriding the getCreatedNotification() method on the create page class: 
use Filament\Notifications\Notification;

protected function getCreatedNotification(): ?Notification
{
    return Notification::make()
        ->success()
        ->title('User registered')
        ->body('The user has been created successfully.');
}
Alternatively, if you’re creating records in a modal action: 
use Filament\Notifications\Notification;
use Filament\Pages\Actions\CreateAction;

CreateAction::make()
    ->successNotification(
       Notification::make()
            ->success()
            ->title('User registered')
            ->body('The user has been created successfully.'),
    )
To disable the notification altogether, return null from the getCreatedNotification() method on the create page class: 
use Filament\Notifications\Notification;

protected function getCreatedNotification(): ?Notification
{
    return null;
}
Alternatively, if you’re creating records in a modal action: 
use Filament\Pages\Actions\CreateAction;

CreateAction::make()
    ->successNotification(null)

​
Lifecycle hooks

Hooks may be used to execute code at various points within a page’s lifecycle, like before a form is saved. To set up a hook, create a protected method on the Create page class with the name of the hook: 
protected function beforeCreate(): void
{
    // ...
}
In this example, the code in the beforeCreate() method will be called before the data in the form is saved to the database. There are several available hooks for the Create page: 
use Filament\Resources\Pages\CreateRecord;

class CreateUser extends CreateRecord
{
    // ...

    protected function beforeFill(): void
    {
        // Runs before the form fields are populated with their default values.
    }

    protected function afterFill(): void
    {
        // Runs after the form fields are populated with their default values.
    }

    protected function beforeValidate(): void
    {
        // Runs before the form fields are validated when the form is submitted.
    }

    protected function afterValidate(): void
    {
        // Runs after the form fields are validated when the form is submitted.
    }

    protected function beforeCreate(): void
    {
        // Runs before the form fields are saved to the database.
    }

    protected function afterCreate(): void
    {
        // Runs after the form fields are saved to the database.
    }
}
Alternatively, if you’re creating records in a modal action: 
use Filament\Pages\Actions\CreateAction;

CreateAction::make()
    ->beforeFormFilled(function () {
        // Runs before the form fields are populated with their default values.
    })
    ->afterFormFilled(function () {
        // Runs after the form fields are populated with their default values.
    })
    ->beforeFormValidated(function () {
        // Runs before the form fields are validated when the form is submitted.
    })
    ->afterFormValidated(function () {
        // Runs after the form fields are validated when the form is submitted.
    })
    ->before(function () {
        // Runs before the form fields are saved to the database.
    })
    ->after(function () {
        // Runs after the form fields are saved to the database.
    })

​
Halting the creation process

At any time, you may call $this->halt() from inside a lifecycle hook or mutation method, which will halt the entire creation process: 
use Filament\Notifications\Actions\Action;
use Filament\Notifications\Notification;

protected function beforeCreate(): void
{
    if (! $this->record->team->subscribed()) {
        Notification::make()
            ->warning()
            ->title('You don\'t have an active subscription!')
            ->body('Choose a plan to continue.')
            ->persistent()
            ->actions([
                Action::make('subscribe')
                    ->button()
                    ->url(route('subscribe'), shouldOpenInNewTab: true),
            ])
            ->send();
    
        $this->halt();
    }
}
Alternatively, if you’re creating records in a modal action: 
use Filament\Notifications\Actions\Action;
use Filament\Notifications\Notification;
use Filament\Pages\Actions\CreateAction;

CreateAction::make()
    ->before(function (CreateAction $action) {
        if (! $this->record->team->subscribed()) {
            Notification::make()
                ->warning()
                ->title('You don\'t have an active subscription!')
                ->body('Choose a plan to continue.')
                ->persistent()
                ->actions([
                    Action::make('subscribe')
                        ->button()
                        ->url(route('subscribe'), shouldOpenInNewTab: true),
                ])
                ->send();
        
            $action->halt();
        }
    })
If you’d like the action modal to close too, you can completely cancel() the action instead of halting it: 
$action->cancel();

​
Authorization

For authorization, Filament will observe any model policies that are registered in your app. Users may access the Create page if the create() method of the model policy returns true.

​
Wizards

You may easily transform the creation process into a multistep wizards. On the page class, add the corresponding HasWizard trait: 
use App\Filament\Resources\CategoryResource;
use Filament\Resources\Pages\CreateRecord;

class CreateCategory extends CreateRecord
{
    use CreateRecord\Concerns\HasWizard;
    
    protected static string $resource = CategoryResource::class;

    protected function getSteps(): array
    {
        return [
            // ...
        ];
    }
}
Inside the getSteps() array, return your wizard steps: 
use Filament\Forms\Components\MarkdownEditor;
use Filament\Forms\Components\TextInput;
use Filament\Forms\Components\Toggle;
use Filament\Forms\Components\Wizard\Step;

protected function getSteps(): array
{
    return [
        Step::make('Name')
            ->description('Give the category a clear and unique name')
            ->schema([
                TextInput::make('name')
                    ->required()
                    ->reactive()
                    ->afterStateUpdated(fn ($state, callable $set) => $set('slug', Str::slug($state))),
                TextInput::make('slug')
                    ->disabled()
                    ->required()
                    ->unique(Category::class, 'slug', fn ($record) => $record),
            ]),
        Step::make('Description')
            ->description('Add some extra details')
            ->schema([
                MarkdownEditor::make('description')
                    ->columnSpan('full'),
            ]),
        Step::make('Visibility')
            ->description('Control who can view it')
            ->schema([
                Toggle::make('is_visible')
                    ->label('Visible to customers.')
                    ->default(true),
            ]),
    ];
}
Alternatively, if you’re creating records in a modal action, simply define a steps() array and pass your Step objects: 
use Filament\Pages\Actions\CreateAction;

CreateAction::make()
    ->steps([
        // ...
    ])
Now, create a new record to see your wizard in action! Edit will still use the form defined within the resource class. If you’d like to allow free navigation, so all the steps are skippable, override the hasSkippableSteps() method: 
public function hasSkippableSteps(): bool
{
    return true;
}
Alternatively, if you’re creating records in a modal action: 
use Filament\Pages\Actions\CreateAction;

CreateAction::make()
    ->steps([
        // ...
    ])
    ->skippableSteps()

​
Sharing fields between the resource form and wizards

If you’d like to reduce the amount of repetition between the resource form and wizard steps, it’s a good idea to extract public static resource functions for your fields, where you can easily retrieve an instance of a field from the resource or the wizard: 
use Filament\Forms;
use Filament\Resources\Form;
use Filament\Resources\Resource;

class CategoryResource extends Resource
{
    public static function form(Form $form): Form
    {
        return $form
            ->schema([
                static::getNameFormField(),
                static::getSlugFormField(),
                // ...
            ]);
    }
    
    public static function getNameFormField(): Forms\Components\TextInput
    {
        return TextInput::make('name')
            ->required()
            ->reactive()
            ->afterStateUpdated(fn ($state, callable $set) => $set('slug', Str::slug($state)));
    }
    
    public static function getSlugFormField(): Forms\Components\TextInput
    {
        return TextInput::make('slug')
            ->disabled()
            ->required()
            ->unique(Category::class, 'slug', fn ($record) => $record);
    }
}

use App\Filament\Resources\CategoryResource;
use Filament\Resources\Pages\CreateRecord;

class CreateCategory extends CreateRecord
{
    use CreateRecord\Concerns\HasWizard;
    
    protected static string $resource = CategoryResource::class;

    protected function getSteps(): array
    {
        return [
            Step::make('Name')
                ->description('Give the category a clear and unique name')
                ->schema([
                    CategoryResource::getNameFormField(),
                    CategoryResource::getSlugFormField(),
                ]),
            // ...
        ];
    }
}

​
Custom view

For further customization opportunities, you can override the static $view property on the page class to a custom view in your app: 
protected static string $view = 'filament.resources.users.pages.create-user';
