--- title: Custom columns --- import Aside from "@components/Aside.astro" ## Introduction You may create your own custom column classes and views, which you can reuse across your project, and even release as a plugin to the community. To create a custom column class and view, you may use the following command: ```bash php artisan make:filament-table-column AudioPlayerColumn ``` This will create the following component class: ```php use Filament\Tables\Columns\Column; class AudioPlayerColumn extends Column { protected string $view = 'filament.tables.columns.audio-player-column'; } ``` It will also create a view file at `resources/views/filament/tables/columns/audio-player-column.blade.php`. ## Accessing the state of the column in the Blade view Inside the Blade view, you may access the [state](overview#column-content-state) of the column using the `$getState()` function: ```blade
{{ $getState() }}
``` ## Accessing the Eloquent record in the Blade view Inside the Blade view, you may access the current table row's Eloquent record using the `$record` variable: ```blade
{{ $record->name }}
``` ## Accessing the current Livewire component instance in the Blade view Inside the Blade view, you may access the current Livewire component instance using `$this`: ```blade @php use Filament\Resources\Users\RelationManagers\ConferencesRelationManager; @endphp
@if ($this instanceof ConferencesRelationManager) You are editing conferences the of a user. @endif
``` ## Accessing the current column instance in the Blade view Inside the Blade view, you may access the current column instance using `$column`. You can call public methods on this object to access other information that may not be available in variables: ```blade
@if ($column->isLabelHidden()) This is a new conference. @endif
``` ## Adding a configuration method to a custom column class You may add a public method to the custom column class that accepts a configuration value, stores it in a protected property, and returns it again from another public method: ```php use Filament\Tables\Columns\Column; class AudioPlayerColumn extends Column { protected string $view = 'filament.tables.columns.audio-player-column'; protected ?float $speed = null; public function speed(?float $speed): static { $this->speed = $speed; return $this; } public function getSpeed(): ?float { return $this->speed; } } ``` Now, in the Blade view for the custom column, you may access the speed using the `$getSpeed()` function: ```blade
{{ $getSpeed() }}
``` Any public method that you define on the custom column class can be accessed in the Blade view as a variable function in this way. To pass the configuration value to the custom column class, you may use the public method: ```php use App\Filament\Tables\Columns\AudioPlayerColumn; AudioPlayerColumn::make('recording') ->speed(0.5) ``` ## Allowing utility injection in a custom column configuration method [Utility injection](overview#column-utility-injection) is a powerful feature of Filament that allows users to configure a component using functions that can access various utilities. You can allow utility injection by ensuring that the parameter type and property type of the configuration allows the user to pass a `Closure`. In the getter method, you should pass the configuration value to the `$this->evaluate()` method, which will inject utilities into the user's function if they pass one, or return the value if it is static: ```php use Closure; use Filament\Tables\Columns\Column; class AudioPlayerColumn extends Column { protected string $view = 'filament.tables.columns.audio-player-column'; 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](overview#component-utility-injection) as a parameter: ```php use App\Filament\Tables\Columns\AudioPlayerColumn; AudioPlayerColumn::make('recording') ->speed(fn (Conference $record): float => $record->isGlobal() ? 1 : 0.5) ```
