新建记录
保存前自定义数据
有时,你需要在保存到数据库之前修改表单数据。你可以定义 mutateFormDataBeforeCreate()
方法,使其接收 $data
数组作为参数,并返回修改过的版本:
protected function mutateFormDataBeforeCreate(array $data): array{ $data['user_id'] = auth()->id(); return $data;}
此外,如果你是通过模态框操作新建记录:
use Filament\Pages\Actions\CreateAction; CreateAction::make() ->mutateFormDataUsing(function (array $data): array { $data['user_id'] = auth()->id(); return $data; })
自定义新建过程
你可以使用 handleRecordCreation()
方法调整记录创建方式:
use Illuminate\Database\Eloquent\Model; protected function handleRecordCreation(array $data): Model{ return static::getModel()::create($data);}
此外,如果你是通过模态框操作新建记录:
use Filament\Pages\Actions\CreateAction;use Illuminate\Database\Eloquent\Model; CreateAction::make() ->using(function (array $data): Model { return static::getModel()::create($data); })
自定义表单重定向
默认情况下,表单保存后,用户会被重定向到资源编辑页,或查看页(当其存在时)。
你可以重写 getRedirectUrl()
自定义表单保存后的跳转页面。
比如,表单可以跳转回列表页:
protected function getRedirectUrl(): string{ return $this->getResource()::getUrl('index');}
如果你想跳转到之前的页面,否则再到首页:
protected function getRedirectUrl(): string{ return $this->previousUrl ?? $this->getResource()::getUrl('index');}
自定义保存通知
当记录创建成功,会派送一个通知给用户,告知操作成功。
要自定义通知标题,在创建页类中定义 getCreatedNotificationTitle()
方法:
protected function getCreatedNotificationTitle(): ?string{ return 'User registered';}
另外,如果你是在模态框操作中创建记录:
use Filament\Pages\Actions\CreateAction; CreateAction::make() ->successNotificationTitle('User registered')
你可以在新建页类中通过重写 getCreatedNotification()
方法自定义整个通知:
use Filament\Notifications\Notification; protected function getCreatedNotification(): ?Notification{ return Notification::make() ->success() ->title('User registered') ->body('The user has been created successfully.');}
另外,如果你是在模态框操作中创建记录:
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.'), )
要完全禁用通知,在新建页类的 getCreatedNotification()
方法中返回 null:
use Filament\Notifications\Notification; protected function getCreatedNotification(): ?Notification{ return null;}
此外,如果你通过模态框操作中新建记录:
use Filament\Pages\Actions\CreateAction; CreateAction::make() ->successNotification(null)
生命周期钩子
钩子可用在页面生命周期的各种节点中执行代码,比如表单数据保存之前。要启用钩子,在页面类中以钩子名新建一个 protected 修饰的方法:
protected function beforeCreate(): void{ // ...}
此例中,beforeCreate()
方法会在表单数据保存到数据库之前被调用。
新建页还有一些可用的钩子:
use Filament\Resources\Pages\CreateRecord; class CreateUser extends CreateRecord{ // ... protected function beforeFill(): void { // 在表单填充默认值之前运行 } protected function afterFill(): void { // 在表单填充默认值之后运行 } protected function beforeValidate(): void { // 表单提交后,表单验证之前运行 } protected function afterValidate(): void { // 表单提交后,表单验证之后运行 } protected function beforeCreate(): void { // 表单字段保存到数据库之前运行 } protected function afterCreate(): void { // 表单字段保存到数据库之后运行 }}
此外,如果你是通过模态框操作新建记录:
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. })
停止新建处理过程
你可以随时在生命周期钩子内或者 mutation 方法内调用 $this->halt()
, 停止整个新建处理过程:
se 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(); }}
此外,如果你是通过模态框操作新建记录:
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(); } })
如果你想同时关闭操作模态框,你也可以用 cancel()
取消操作,而不必 halt()
:
$action->cancel();
授权
关于授权,Filament 会监听所有应用中注册的模型策略。
如果模型策略的 create()
方法中返回的是 true()
,用户可以访问新建页。
Wizards
你可以简单地将新建过程转换成多个步骤。
在页面类中,添加相应的 HasWizard
trait:
use App\Filament\Resources\CategoryResource;use Filament\Resources\Pages\CreateRecord; class CreateCategory extends CreateRecord{ use CreateRecord\Concerns\HasWizard; protected static string $resource = CategoryResource::class; protected function getSteps(): array { return [ // ... ]; }}
在 getSteps()
数组中,返回 wizard 步骤:
use Filament\Forms\Components\MarkdownEditor;use Filament\Forms\Components\TextInput;use Filament\Forms\Components\Toggle;use Filament\Forms\Components\Wizard\Step; protected function getSteps(): array{ return [ Step::make('Name') ->description('Give the category a clear and unique name') ->schema([ TextInput::make('name') ->required() ->reactive() ->afterStateUpdated(fn ($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), ]), ];}
此外,如果你通过模态框中新建记录,只需定义 steps()
数组并传入 Step
对象:
use Filament\Pages\Actions\CreateAction; CreateAction::make() ->steps([ // ... ])
现在,你可以访问新建页面,查看在操作中查看向导了!编辑页仍然可以使用资源类中定义的表单。
如果你想要允许自由导航,使所有步骤都可以跳过,重写 hasSkippableSteps()
方法:
public function hasSkippableSteps(): bool{ return true;}
此外,如果你通过模态框中新建记录:
use Filament\Pages\Actions\CreateAction; CreateAction::make() ->steps([ // ... ]) ->skippableSteps()
资源表单和向导中共用字段
如果你想减少资源表单和向导步骤之间的重复工作量,可以为表单字段提取出公共的静态资源方法,这样就能简单地从中找到资源或者向导需要字段实例:
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(), ]), // ... ]; }}
自定义视图
要进一步自定义,你可以覆盖页面类的静态 $view
属性:
protected static string $view = 'filament.resources.users.pages.create-user';
