Prime components - Schema

简介

Within Filament schemas, prime components are the most basic building blocks that can be used to insert arbitrary content into a schema, such as text and images. As the name suggests, prime components are not divisible and cannot be made simpler. Filament provides a set of built-in prime components:

Text
Icon
Image
Unordered list

You may also create your own custom components to add your own arbitrary content to a schema.

An example of using prime components to set up two-factor authentication.

In this example, prime components are being used to display instructions to the user, a QR code that the user can scan, and list of recovery codes that the user can save:

use Filament\Actions\Action;
use Filament\Schemas\Components\Image;
use Filament\Schemas\Components\Section;
use Filament\Schemas\Components\Text;
use Filament\Schemas\Components\UnorderedList;
use Filament\Support\Enums\FontWeight;
use Filament\Support\Enums\TextSize;

$schema
    ->components([
        Text::make('Scan this QR code with your authenticator app:')
            ->color('neutral'),
        Image::make(
            url: asset('images/qr.jpg'),
            alt: 'QR code to scan with an authenticator app',
        )
            ->imageHeight('12rem')
            ->alignCenter(),
        Section::make()
            ->schema([
                Text::make('Please save the following recovery codes in a safe place. They will only be shown once, but you\'ll need them if you lose access to your authenticator app:')
                    ->weight(FontWeight::Bold)
                    ->color('neutral'),
                UnorderedList::make(fn (): array => array_map(
                    fn (string $recoveryCode): Text => Text::make($recoveryCode)
                        ->copyable()
                        ->fontFamily(FontFamily::Mono)
                        ->size(TextSize::ExtraSmall)
                        ->color('neutral'),
                    ['tYRnCqNLUx-3QOLNKyDiV', 'cKok2eImKc-oWHHH4VhNe', 'C0ZstEcSSB-nrbyk2pv8z', '49EXLRQ8MI-FpWywpSDHE', 'TXjHnvkUrr-KuiVJENPmJ', 'BB574ookll-uI20yxP6oa', 'BbgScF2egu-VOfHrMtsCl', 'cO0dJYqmee-S9ubJHpRFR'],
                ))
                    ->size(TextSize::ExtraSmall),
            ])
            ->compact()
            ->secondary(),
    ])

Although text can be rendered in a schema using an infolist text entry, entries are intended to render a label-value detail about an entity (like an Eloquent model), and not to render arbitrary text. Prime components are more suitable for this purpose. Infolists can be considered more similar to description lists in HTML.

Prime component classes can be found in the Filament\Schemas\Components namespace. They reside within the schema array of components.

文本组件

使用 Text 组件，可以将文本插入到 Schema。请将文本内容传入到 make() 方法中：

use Filament\Schemas\Components\Text;

Text::make('Modifying these permissions may give users access to sensitive information.')

要渲染原始 HTML 内容，请将 HtmlString 对象传递给 make() 方法：

use Filament\Schemas\Components\Text;
use Illuminate\Support\HtmlString;

Text::make(new HtmlString('<strong>Warning:</strong> Modifying these permissions may give users access to sensitive information.'))

NOTE

请注意，你需要确保 HTML 渲染是安全的，否则应用可能会有 XSS 攻击漏洞。

要渲染 Markdown，你可以使用 Laravel 的 str() 辅助函数将 Markdown 转换成 HTML，并将其转换成 HtmlString 对象：

use Filament\Schemas\Components\Text;

Text::make(
    str('**Warning:** Modifying these permissions may give users access to sensitive information.')
        ->inlineMarkdown()
        ->toHtmlString(),
)

As well as allowing a static value, the make() method also accepts a function to dynamically calculate it. You can inject various utilities into the function as parameters.

Utility	Type	Parameter	Description
Component	`Filament\Schemas\Components\Component`	`$component`	The current component instance.
Get function	`Filament\Schemas\Components\Utilities\Get`	`$get`	A function for retrieving values from the current schema data. Validation is not run on form fields.
Livewire	`Livewire\Component`	`$livewire`	The Livewire component instance.
Eloquent model FQN	`?string<Illuminate\Database\Eloquent\Model>`	`$model`	The Eloquent model FQN for the current schema.
Operation	`string`	`$operation`	The current operation being performed by the schema. Usually `create`, `edit`, or `view`.
Eloquent record	`?Illuminate\Database\Eloquent\Model`	`$record`	The Eloquent record for the current schema.
