Prime 组件

简介

在 Filament Schema 中，Prime 组件是最基本的构建块，可用于将任意内容（例如文本和图像）插入到 Schema 中。顾名思义，Prime 组件不可分割，且无法简化。Filament 提供了一组内置的 Prime 组件：

• Text
• Icon
• Image
• Unordered list

你也可以创建自己的自定义组件以将自己的任意内容添加到 Schema 中。

本例中，Prime 组件用于向用户显示说明、用户可以扫描的二维码以及用户可以保存的恢复码列表：

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(),
    ])

虽然可以使用信息列表的文本条目 在 Schema 渲染文本，但条目旨在渲染实体的标签-值详细信息（例如 Eloquent 模型），而不是渲染任意文本。Prime 组件更适合此目的。信息可以被当作更类似于 HTML 中的 描述列表。

Prime 组件类可以在 Filament\Schemas\Components 命名空间中找到。它们位于组件的 Schma 数组中。

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(),
)

除了允许静态值之外，make() 方法也可以接受函数来动态计算其值。你可以将各种 utility 作为参数注入到函数中。

自定义文本颜色

你可以为文本设置颜色：

use Filament\Schemas\Components\Text;

Text::make('Information')
    ->color('info')

除了允许静态值之外，color() 方法也可以接受函数来动态计算其值。你可以将各种 utility 作为参数注入到函数中。

使用中性颜色

， 默认情况下，文本颜色设置为 gray，与背景相比通常相当暗淡。你可以使用 color('neutral') 方法将其变得更暗：

use Filament\Schemas\Components\Text;

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

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

显示为徽章

默认情况下，文本非常简单，没有背景色。你可以使用 badge() 方法使其显示为“徽章”。一个很好的用例是状态，其中可能需要显示一个带有与状态匹配的颜色的徽章：

use Filament\Schemas\Components\Text;

Text::make('Warning')
    ->color('warning')
    ->badge()

或者，你可以传入一个布尔值控制文本是否显示为徽章：

use Filament\Schemas\Components\Text;

Text::make('Warning')
    ->color('warning')
    ->badge(FeatureFlag::active())

除了允许静态值之外，badge() 方法也可以接受函数来动态计算其值。你可以将各种 utility 作为参数注入到函数中。

自定义文本大小

文本默认字体较小，但你可以将其更改为 TextSize::ExtraSmall、TextSize::Medium 或 TextSize::Large。

例如，你可以使用 size(TextSize::Large) 放大文本：

use Filament\Schemas\Components\Text;
use Filament\Support\Enums\TextSize;

Text::make('Modifying these permissions may give users access to sensitive information.')
    ->size(TextSize::Large)

自定义字体粗细

文本条目默认使用常规字体粗细，但你可以将其更改为以下任意选项：FontWeight::Thin、FontWeight::ExtraLight、FontWeight::Light、FontWeight::Medium、FontWeight::SemiBold、FontWeight::Bold、FontWeight::ExtraBold 或 FontWeight::Black。

例如，你可以使用 weight(FontWeight::Bold) 将字体设置为粗体：

use Filament\Schemas\Components\Text;
use Filament\Support\Enums\FontWeight;

Text::make('Modifying these permissions may give users access to sensitive information.')
    ->weight(FontWeight::Bold)

除了允许静态值之外，weight() 方法也可以接受函数来动态计算其值。你可以将各种 utility 作为参数注入到函数中。

使用 JavaScript 确定文本内容

你可以使用 JavaScript 确定文本内容。如果你想根据 表单字段 的状态显示不同的消息，而无需向服务器发出重新渲染 Schema 的请求，这将非常有用。为此，你可以使用 js() 方法：

use Filament\Schemas\Components\Text;

Text::make(<<<'JS'
    $get('name') ? `Hello, ${$get('name')}` : 'Please enter your name.'
    JS)
    ->js()

$state 和 $get() utility 可以在 JavaScript 上下文中使用，因此你可以使用它们来获取 Schema 中字段的状态。

图标组件

使用 Icon 组件，你可以将图标插入到 Schema 中。请将图标 传入到 make() 方法中：

use Filament\Schemas\Components\Icon;
use Filament\Support\Icons\Heroicon;

Icon::make(Heroicon::Star)

除了允许静态值之外，make() 方法也可以接受函数来动态计算其值。你可以将各种 utility 作为参数注入到函数中。

    alt: 'QR code to scan with an authenticator app',
)
    ->imageWidth('12rem')

Image::make(

    alt: 'QR code to scan with an authenticator app',
)
    ->imageHeight('12rem')

例如，你可以使用 size(TextSize::Large) 放大列表项：

use Filament\Schemas\Components\Text;

Adding extra HTML attributes to a prime component

你可以通过 extraAttributes() 方法向组件传递额外的 HTML 属性，这些属性将被合并到其外部 HTML 元素上。这些属性应该用一个数组表示，其中键是属性名称，值是属性值：

use Filament\Schemas\Components\Text;

Text::make('Modifying these permissions may give users access to sensitive information.')
    ->extraAttributes(['class' => 'custom-text-style'])

除了允许静态值之外，extraAttributes() 方法也可以接受函数来动态计算其值。你可以将各种 utility 作为参数注入到函数中。
