Checkbox list

简介

复选框列表(CheckboxList)组件允许你从预定义选项列表中选择多个值:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        'tailwind' => 'Tailwind CSS',
        'alpine' => 'Alpine.js',
        'laravel' => 'Laravel',
        'livewire' => 'Laravel Livewire',
    ])
除了允许静态数组之外,options() 方法也接受一个函数来动态计算其值。你可以将多个 utility 作为参数注入到该函数中。 Learn more about utility injection.
Utility Type Parameter Description
Field Filament\Forms\Components\Field $component The current field component instance.
Get function Filament\Schemas\Components\Utilities\Get $get A function for retrieving values from the current form data. Validation is not run.
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.
Raw state mixed $rawState The current value of the field, before state casts were applied. Validation is not run.
Eloquent record ?Illuminate\Database\Eloquent\Model $record The Eloquent record for the current schema.
State mixed $state The current value of the field. Validation is not run.
Checkbox list

这些选项以 JSON 格式返回。如果你使用 Eloquent 保存数据,你应该添加 array 强制转换(cast) 到对应的模型属性上:

use Illuminate\Database\Eloquent\Model;

class App extends Model
{
    protected $casts = [
        'technologies' => 'array',
    ];

    // ...
}

设置选项描述

使用 descriptions() 方法,你可以选择为每个选项提供描述。该方法接收一个普通文本字符串,或者 Illuminate\Support\HtmlStringIlluminate\Contracts\Support\Htmlable 实例。这就允许你在描述中渲染 HTML 甚至 Markdown 文本:

use Filament\Forms\Components\CheckboxList;
use Illuminate\Support\HtmlString;

CheckboxList::make('technologies')
    ->options([
        'tailwind' => 'Tailwind CSS',
        'alpine' => 'Alpine.js',
        'laravel' => 'Laravel',
        'livewire' => 'Laravel Livewire',
    ])
    ->descriptions([
        'tailwind' => 'A utility-first CSS framework for rapidly building modern websites without ever leaving your HTML.',
        'alpine' => new HtmlString('A rugged, minimal tool for composing behavior <strong>directly in your markup</strong>.'),
        'laravel' => str('A **web application** framework with expressive, elegant syntax.')->inlineMarkdown()->toHtmlString(),
        'livewire' => 'A full-stack framework for Laravel building dynamic interfaces simple, without leaving the comfort of Laravel.',
    ])
除了允许静态数组之外,descriptions() 方法也接受一个函数来动态计算其值。你可以将多个 utility 作为参数注入到该函数中。 Learn more about utility injection.
Utility Type Parameter Description
Field Filament\Forms\Components\Field $component The current field component instance.

Eloquent record ?Illuminate\Database\Eloquent\Model $record The Eloquent record for the current schema.
State mixed $state The current value of the field. Validation is not run.
Checkbox list with option descriptions

NOTE

请确保在描述中使用与选项数组相同的 key,这样描述才能与选项匹配。

将选项拆分成多列

使用 columns() 方法,你可以将选项拆分成多列:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->columns(2)
除了允许静态值之外,columns() 方法也接受一个函数来动态计算其值。你可以将多个 utility 作为参数注入到该函数中。 Learn more about utility injection.

Checkbox list with 2 columns

该方法接收和网格columns() 方法相同的选项。这就允许你在不同的临界点中响应式地自定义列数。

设置网格方向

默认情况下,列中的复选框列表按垂直方向排序。如果你想将其进行水平排列,你可以使用 gridDirection(GridDirection::Row) 方法:

use Filament\Forms\Components\CheckboxList;
use Filament\Support\Enums\GridDirection;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->columns(2)
    ->gridDirection(GridDirection::Row)

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->searchable()
Searchable checkbox list

Optionally, you may pass a boolean value to control if the options should be searchable or not:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->searchable(FeatureFlag::active())
除了允许静态值之外,searchable() 方法也接受一个函数来动态计算其值。你可以将多个 utility 作为参数注入到该函数中。 Learn more about utility injection.

批量切换复选框

使用 bulkToggleable() 方法,你可以允许用户一次性切换所有复选框:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->bulkToggleable()
Bulk toggleable checkbox list

Optionally, you may pass a boolean value to control if the checkboxes should be bulk toggleable or not:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->bulkToggleable(FeatureFlag::active())
除了允许静态值之外,bulkToggleable() 方法也接受一个函数来动态计算其值。你可以将多个 utility 作为参数注入到该函数中。 Learn more about utility injection.
Utility Type Parameter Description

禁用特定选项

使用 disableOptionWhen() 方法,可以禁用特定选项。它接受一个闭包,在闭包中你可以检测选项是否是特定要被禁用的 $value 值:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        'tailwind' => 'Tailwind CSS',
        'alpine' => 'Alpine.js',
        'laravel' => 'Laravel',
        'livewire' => 'Laravel Livewire',
    ])
    ->disableOptionWhen(fn (string $value): bool => $value === 'livewire')
You can inject various utilities into the function as parameters. Learn more about utility injection.
Utility Type Parameter Description
Field Filament\Forms\Components\Field $component The current field component instance.
Get function Filament\Schemas\Components\Utilities\Get $get A function for retrieving values from the current form data. Validation is not run.
Option label string | Illuminate\Contracts\Support\Htmlable $label The label of the option to disable.

Eloquent record ?Illuminate\Database\Eloquent\Model $record The Eloquent record for the current schema.
State mixed $state The current value of the field. Validation is not run.
Option value mixed $value The value of the option to disable.

如果你想检索选项是否未被禁用,比如,为了验证数据,你可以使用 getEnabledOptions()

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        'tailwind' => 'Tailwind CSS',
        'alpine' => 'Alpine.js',
        'laravel' => 'Laravel',
        'livewire' => 'Laravel Livewire',
        'heroicons' => 'SVG icons',
    ])
    ->disableOptionWhen(fn (string $value): bool => $value === 'heroicons')
    ->in(fn (CheckboxList $component): array => array_keys($component->getEnabledOptions()))

For more information about the in() function, please see the Validation documentation.

在选项标签中允许 HTML

默认情况下,Filament 将在选项标签中转义 HTML。如果你想允许使用 HTML,可以使用 allowHtml() 方法:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technology')
    ->options([
        'tailwind' => '<span class="text-blue-500">Tailwind</span>',
        'alpine' => '<span class="text-green-500">Alpine</span>',
        'laravel' => '<span class="text-red-500">Laravel</span>',
        'livewire' => '<span class="text-pink-500">Livewire</span>',
    ])
    ->searchable()
    ->allowHtml()

NOTE

请注意,你需要确保 HTML 的渲染是安全的,否则你的应用将容易受到 XSS 攻击。

Optionally, you may pass a boolean value to control if the options should allow HTML or not:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technology')
    ->options([
        'tailwind' => '<span class="text-blue-500">Tailwind</span>',
        'alpine' => '<span class="text-green-500">Alpine</span>',
        'laravel' => '<span class="text-red-500">Laravel</span>',
        'livewire' => '<span class="text-pink-500">Livewire</span>',
    ])
    ->searchable()
    ->allowHtml(FeatureFlag::active())
除了允许静态值之外,allowHtml() 方法也接受一个函数来动态计算其值。你可以将多个 utility 作为参数注入到该函数中。 Learn more about utility injection.
Utility Type Parameter Description
Field Filament\Forms\Components\Field $component The current field component instance.
Get function Filament\Schemas\Components\Utilities\Get $get A function for retrieving values from the current form data. Validation is not run.
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.

Eloquent record ?Illuminate\Database\Eloquent\Model $record The Eloquent record for the current schema.
State mixed $state The current value of the field. Validation is not run.

集成 Eloquent 关联

如果你在 Livewire 组件内创建表单,请确保设置好表单模型。否则,Filament 不知道应该使用哪个模型去检索关联。

你可以使用 CheckboxList 上的 relationship() 方法配置 BelongsToMany 关联。Filament 将从关联中加载项目数据,并在表单提交后将其保存回关联的中间表中。titleAttribute 是用于为每个选项生成标签的字段名:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->relationship(titleAttribute: 'name')

NOTE

disabled()relationship() 一起使用时,请确保 disabled() 的调用在 relationship() 之前。这可以确保在 relationship() 中进行 dehydrated() 调用不会被 disabled() 调用覆盖:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->disabled()
    ->relationship(titleAttribute: 'name')

自定义关联查询

你可以使用 relationship() 方法的 modifyOptionsQueryUsing 参数,自定义检索选项的数据库查询:

use Filament\Forms\Components\CheckboxList;
use Illuminate\Database\Eloquent\Builder;

CheckboxList::make('technologies')
    ->relationship(
        titleAttribute: 'name',
        modifyQueryUsing: fn (Builder $query) => $query->withTrashed(),
    )
The modifyQueryUsing argument can inject various utilities into the function as parameters. Learn more about utility injection.
Utility Type Parameter Description
Field Filament\Forms\Components\Field $component The current field component instance.
Get function Filament\Schemas\Components\Utilities\Get $get A function for retrieving values from the current form data. Validation is not run.
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.
Query Illuminate\Database\Eloquent\Builder $query The Eloquent query builder to modify.
Raw state mixed $rawState The current value of the field, before state casts were applied. Validation is not run.
Eloquent record ?Illuminate\Database\Eloquent\Model $record The Eloquent record for the current schema.
State mixed $state The current value of the field. Validation is not run.

自定义关联选项标签

如果你想要自定义每个选项的标签,比如使之更具描述性,或者将姓和名组合,你可以在数据库迁移中使用虚拟字段:

$table->string('full_name')->virtualAs('concat(first_name, \' \', last_name)');
use Filament\Forms\Components\CheckboxList;

CheckboxList::make('authors')
    ->relationship(titleAttribute: 'full_name')

另外,你也可以使用 getOptionLabelFromRecordUsing() 方法将选项的 Eloquent 模型转换成标签:

use Filament\Forms\Components\CheckboxList;
use Illuminate\Database\Eloquent\Builder;
use Illuminate\Database\Eloquent\Model;

CheckboxList::make('authors')
    ->relationship(
        modifyQueryUsing: fn (Builder $query) => $query->orderBy('first_name')->orderBy('last_name'),
    )
    ->getOptionLabelFromRecordUsing(fn (Model $record) => "{$record->first_name} {$record->last_name}")
The getOptionLabelFromRecordUsing() method can inject various utilities into the function as parameters. Learn more about utility injection.
Utility Type Parameter Description

Eloquent record Illuminate\Database\Eloquent\Model $record The Eloquent record to get the option label for.
State mixed $state The current value of the field. Validation is not run.

将中间表数据保存到关联

如果你的中间表有额外的列,你可以使用 pivotData() 方法指定应该在其中保存的数据:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('primaryTechnologies')
    ->relationship(name: 'technologies', titleAttribute: 'name')
    ->pivotData([
        'is_primary' => true,
    ])
除了允许静态值之外,pivotData() 方法也接受一个函数来动态计算其值。你可以将多个 utility 作为参数注入到该函数中。 Learn more about utility injection.

State mixed $state The current value of the field. Validation is not run.

设置没有搜索结果的自定义消息

使用可搜索的复选框列表时,你可能希望在没有找到搜索结果时显示一条自定义消息。为此,请使用 noSearchResultsMessage() 方法:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->searchable()
    ->noSearchResultsMessage('No technologies found.')
除了允许静态值之外,noSearchResultsMessage() 方法也接受一个函数来动态计算其值。你可以将多个 utility 作为参数注入到该函数中。 Learn more about utility injection.

设置自定义搜索提示

使用可搜索的复选框列表时,你可能希望在用户还未输入搜索条件时显示自定义消息。为此,请使用 searchPrompt() 方法:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->searchable()
    ->searchPrompt('Search for a technology')

State mixed $state The current value of the field. Validation is not run.

调整搜索抖动

默认情况下,当用户输入到可搜索的复选框列表时,Filament 会在搜索选项之前等待 1000 毫秒(1 秒)。如果用户持续输入到搜索框,搜索之间也会等待 1000 毫秒。你可以使用 searchDebounce() 方法,对此进行修改:

use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->searchable()
    ->searchDebounce(500)

  • selectAllAction()
  • deselectAllAction()

下面是一个如何自定义 Action 的示例:

use Filament\Actions\Action;
use Filament\Forms\Components\CheckboxList;

CheckboxList::make('technologies')
    ->options([
        // ...
    ])
    ->selectAllAction(
        fn (Action $action) => $action->label('Select all technologies'),
    )
The action registration methods can inject various utilities into the function as parameters. Learn more about utility injection.
