自定义 Entry

简介

你可以创建你自己的自定义条目(Entry)类及视图，它可以在整个应用中进行重用，甚至可以将其作为插件发布到社区。

你可以创建自定义条目(Entry)类及视图，请要使用如下命令：

php artisan make:filament-infolist-entry AudioPlayerEntry

该命令将创建以下组件类：

use Filament\Infolists\Components\Entry;

class AudioPlayerEntry extends Entry
{
    protected string $view = 'filament.infolists.components.audio-player-entry';
}

同时生成一个视图文件：resources/views/filament/infolists/components/audio-player-entry.blade.php。

NOTE

Filament 信息列表条目不是 Livewire 组件。在条目类中定义公共属性和方法不会使之在 Blade 视图中可访问到。

在 Blade 视图中访问条目状态

在 Blade 视图中，你可以使用 $getState() 函数访问条目的状态值：

<x-dynamic-component
    :component="$getEntryWrapperView()"
    :entry="$entry"
>
    {{ $getState() }}
</x-dynamic-component>

在 Blade 视图中访问其他组件的状态

在 Blade 视图中，你可以使用 $get() 函数访问 Schema 中其他组件的状态值：

<x-dynamic-component
    :component="$getEntryWrapperView()"
    :entry="$entry"
>
    {{ $get('email') }}
</x-dynamic-component>

TIP

Unless a form field is reactive, the Blade view will not refresh when the value of the field changes, only when the next user interaction occurs that makes a request to the server. If you need to react to changes in a field's value, it should be live().

在 Blade 视图中访问 Eloquent 记录

Inside the Blade view, you may access the current Eloquent record using the $record variable:

<x-dynamic-component
    :component="$getEntryWrapperView()"
    :entry="$entry"
>
    {{ $record->name }}
</x-dynamic-component>

在 Blade 视图中访问当前操作

Inside the Blade view, you may access the current operation, usually create, edit or view, using the $operation variable:

<x-dynamic-component
    :component="$getEntryWrapperView()"
    :entry="$entry"
>
    @if ($operation === 'create')
        This is a new conference.
    @else
        This is an existing conference.
    @endif
</x-dynamic-component>

在 Blade 视图中访问当前 Livewire 组件

Inside the Blade view, you may access the current Livewire component instance using $this:

@php
    use Filament\Resources\Users\RelationManagers\ConferencesRelationManager;
@endphp

<x-dynamic-component
    :component="$getEntryWrapperView()"
    :entry="$entry"
>
    @if ($this instanceof ConferencesRelationManager)
        You are editing conferences the of a user.
    @endif
</x-dynamic-component>

在 Blade 视图中访问当前 Entry 实例

Inside the Blade view, you may access the current entry instance using $entry. You can call public methods on this object to access other information that may not be available in variables:

<x-dynamic-component
    :component="$getEntryWrapperView()"
    :entry="$entry"
>
    @if ($entry->isLabelHidden())
        This is a new conference.
    @endif
</x-dynamic-component>

Adding a configuration method to a custom entry class

You may add a public method to the custom entry class that accepts a configuration value, stores it in a protected property, and returns it again from another public method:

use Filament\Infolists\Components\Entry;

class AudioPlayerEntry extends Entry
{
    protected string $view = 'filament.infolists.components.audio-player-entry';
    
    protected ?float $speed = null;

    public function speed(?float $speed): static
    {
        $this->speed = $speed;

        return $this;
    }

    public function getSpeed(): ?float
    {
        return $this->speed;
    }
}

Now, in the Blade view for the custom entry, you may access the speed using the $getSpeed() function:

<x-dynamic-component
    :component="$getEntryWrapperView()"
    :entry="$entry"
>
    {{ $getSpeed() }}
</x-dynamic-component>

Any public method that you define on the custom entry class can be accessed in the Blade view as a variable function in this way.

To pass the configuration value to the custom entry class, you may use the public method:

use App\Filament\Infolists\Components\AudioPlayerEntry;

AudioPlayerEntry::make('recording')
    ->speed(0.5)

Allowing utility injection in a custom entry configuration method

Utility injection is a powerful feature of Filament that allows users to configure a component using functions that can access various utilities. You can allow utility injection by ensuring that the parameter type and property type of the configuration allows the user to pass a Closure. In the getter method, you should pass the configuration value to the $this->evaluate() method, which will inject utilities into the user's function if they pass one, or return the value if it is static:

use Closure;
use Filament\Infolists\Components\Entry;

class AudioPlayerEntry extends Entry
{
    protected string $view = 'filament.infolists.components.audio-player-entry';
    
    protected float | Closure | null $speed = null;

    public function speed(float | Closure | null $speed): static
    {
        $this->speed = $speed;

        return $this;
    }

    public function getSpeed(): ?float
    {
        return $this->evaluate($this->speed);
    }
}

Now, you can pass a static value or a function to the speed() method, and inject any utility as a parameter:

use App\Filament\Infolists\Components\AudioPlayerEntry;

AudioPlayerEntry::make('recording')
    ->speed(fn (Conference $record): float => $record->isGlobal() ? 1 : 0.5)
