Custom components

#Inserting a Blade view into a schema

You may use a “view” component to insert a Blade view into a schema arbitrarily:

use Filament\Schemas\Components\View;

View::make('filament.schemas.components.chart')

This assumes that you have a resources/views/filament/schemas/components/chart.blade.php file.

#Rendering the component’s child schema

You may pass an array of child schema components to the schema() method of the component:

use Filament\Forms\Components\TextInput;
use Filament\Schemas\Components\View;

View::make('filament.schemas.components.chart')
    ->schema([
        TextInput::make('subtotal'),
        TextInput::make('total'),
    ])

Inside the Blade view, you may render the component’s schema() using the $getChildSchema() function:

<div>
    {{ $getChildSchema() }}
</div>

#Accessing the state of another component in the Blade view

Inside the Blade view, you may access the state of another component in the schema using the $get() function:

<div>
    {{ $get('email') }}
</div>

#Accessing the Eloquent record in the Blade view

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

<div>
    {{ $record->name }}
</div>

#Accessing the current operation in the Blade view

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

<p>
    @if ($operation === 'create')
        This is a new post.
    @else
        This is an existing post.
    @endif
</p>

#Accessing the current Livewire component instance in the Blade view

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

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

<p>
    @if ($this instanceof PostsRelationManager)
        You are editing posts the of a user.
    @endif
</p>

#Accessing the current component instance in the Blade view

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

<p>
    @if ($schemaComponent->getState())
        This is a new post.
    @endif
</p>

#Inserting a Livewire component into a schema

You may insert a Livewire component directly into a schema:

use App\Livewire\Chart;
use Filament\Schemas\Components\Livewire;

Livewire::make(Chart::class)

If you are rendering multiple of the same Livewire component, please make sure to pass a unique key() to each:

use App\Livewire\Chart;
use Filament\Schemas\Components\Livewire;

Livewire::make(Chart::class)
    ->key('chart-first')

Livewire::make(Chart::class)
    ->key('chart-second')

Livewire::make(Chart::class)
    ->key('chart-third')

#Passing parameters to a Livewire component

You can pass an array of parameters to a Livewire component:

use App\Livewire\Chart;
use Filament\Schemas\Components\Livewire;

Livewire::make(Chart::class, ['bar' => 'baz'])

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.

Learn more about utility injection.

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.

Now, those parameters will be passed to the Livewire component’s mount() method:

class Chart extends Component
{
    public function mount(string $bar): void
    {       
        // ...
    }
}

Alternatively, they will be available as public properties on the Livewire component:

class Chart extends Component
{
    public string $bar;
}

#Accessing the current record in the Livewire component

You can access the current record in the Livewire component using the $record parameter in the mount() method, or the $record property:

use Illuminate\Database\Eloquent\Model;

class Chart extends Component
{
    public function mount(?Model $record = null): void
    {       
        // ...
    }
    
    // or
    
    public ?Model $record = null;
}

Please be aware that when the record has not yet been created, it will be null. If you’d like to hide the Livewire component when the record is null, you can use the hidden() method:

use Filament\Schemas\Components\Livewire;
use Illuminate\Database\Eloquent\Model;

Livewire::make(Chart::class)
    ->hidden(fn (?Model $record): bool => $record === null)

#Lazy loading a Livewire component

You may allow the component to lazily load using the lazy() method:

use Filament\Schemas\Components\Livewire;
use App\Livewire\Chart;

Livewire::make(Chart::class)
    ->lazy()       

#Custom component classes

You may create your own custom component classes and views, which you can reuse across your project, and even release as a plugin to the community.

To create a custom component class and view, you may use the following command:

php artisan make:filament-schema-component Chart

This will create the following component class:

use Filament\Schemas\Components\Component;

class Chart extends Component
{
    protected string $view = 'filament.schemas.components.chart';

    public static function make(): static
    {
        return app(static::class);
    }
}

It will also create a view file at resources/views/filament/schemas/components/chart.blade.php.

You may use the same utilities as you would when inserting a Blade view into a schema to render the component’s child schema, access another component’s live state, access the current Eloquent record, access the current operation, access the current Livewire component instance, and access the current component instance.

#Adding a configuration method to a custom component class

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

use Filament\Schemas\Components\Component;

class Chart extends Component
{
    protected string $view = 'filament.schemas.components.chart';
    
    protected ?string $heading = null;

    public static function make(): static
    {
        return app(static::class);
    }

    public function heading(?string $heading): static
    {
        $this->heading = $heading;

        return $this;
    }

    public function getHeading(): ?string
    {
        return $this->heading;
    }
}

Now, in the Blade view for the custom component, you may access the heading using the $getHeading() function:

<div>
    {{ $getHeading() }}
</div>

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

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

use App\Filament\Schemas\Components\Chart;

Chart::make()
    ->heading('Sales')

#Allowing utility injection in a custom component 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\Schemas\Components\Component;

class Chart extends Component
{
    protected string $view = 'filament.schemas.components.chart';
    
    protected string | Closure | null $heading = null;

    public static function make(): static
    {
        return app(static::class);
    }

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

        return $this;
    }

    public function getHeading(): ?string
    {
        return $this->evaluate($this->heading);
    }
}

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

use App\Filament\Schemas\Components\Chart;

Chart::make()
    ->heading(fn (Product $record): string => "{$record->name} Sales")

#Accepting a configuration value in the constructor of a custom component class

You may accept a configuration value in the make() constructor method of the custom component and pass it to the corresponding setter method:

use Closure;
use Filament\Schemas\Components\Component;

class Chart extends Component
{
    protected string $view = 'filament.schemas.components.chart';
    
    protected string | Closure | null $heading = null;

    public function __construct(string | Closure | null $heading = null)
    {
        $this->heading($heading)
    }

    public static function make(string | Closure | null $heading = null): static
    {
        return app(static::class, ['heading' => $heading]);
    }
    
    public function heading(string | Closure | null $heading): static
    {
        $this->heading = $heading;

        return $this;
    }

    public function getHeading(): ?string
    {
        return $this->evaluate($this->heading);
    }
}
