How to Execute a Function on Button Click and Component Render in Custom Filament Fields?

Hi, I am creating custom fields and want to include a button that, when clicked, executes a function in my component. The function, sendOtp, queries the database and calls services, etc. Additionally, I want to call this function when the component is rendered for the first time. Here is my base code: Component:

<?php

namespace App\Forms\Components\Fields;

use Filament\Forms\Components\Field;

class AuthField extends Field
{
    protected string $view = 'forms.components.fields.auth-field';

    public function sendOtp(): void
    {
        // send otp logic
        ray('send otp');
    }
}

<?php

namespace App\Forms\Components\Fields;

use Filament\Forms\Components\Field;

class AuthField extends Field
{
    protected string $view = 'forms.components.fields.auth-field';

    public function sendOtp(): void
    {
        // send otp logic
        ray('send otp');
    }
}

Blade:

<x-dynamic-component
    :component="$getFieldWrapperView()"
    :field="$field"
>
    <div
        x-data="{
            state: $wire.$entangle('{{ $getStatePath() }}'),
         }"
        x-init="sendOtp"
    >
        <input x-model="state" type="text" maxlength="6" minlength="6" placeholder="000000">

        <button type="button">
            Send OTP
        </button>
    </div>
</x-dynamic-component>

<x-dynamic-component
    :component="$getFieldWrapperView()"
    :field="$field"
>
    <div
        x-data="{
            state: $wire.$entangle('{{ $getStatePath() }}'),
         }"
        x-init="sendOtp"
    >
        <input x-model="state" type="text" maxlength="6" minlength="6" placeholder="000000">

        <button type="button">
            Send OTP
        </button>
    </div>
</x-dynamic-component>

How can I make the button execute the sendOtp function on click, and also call this function when the component is rendered for the first time?

Hi, To achieve your goal of creating a custom field with a button that executes the sendOtp function when clicked and also calls this function when the component is rendered for the first time, you can follow these steps: Component:...

sendOpt method should exist in the pages, in your CreatePage, EditPage... another way would be registering actions in the field https://filamentphp.com/docs/3.x/forms/actions/#adding-an-action-to-a-custom-form-component

namespace App\Forms\Components\Fields;

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

class AuthField extends Field
{
    protected string $view = 'forms.components.fields.auth-field';

    protected function setUp(): void
    {
        parent::setUp();

        $this->registerActions([
            Action::make('sendOtp')
                ->label('Send OTP')
                ->action(fn () => $this->sendOtp()),
        ]);
    }

    public function sendOtp(): void
    {
        // Send OTP logic
        ray('send otp');
    }
}

namespace App\Forms\Components\Fields;

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

class AuthField extends Field
{
    protected string $view = 'forms.components.fields.auth-field';

    protected function setUp(): void
    {
        parent::setUp();

        $this->registerActions([
            Action::make('sendOtp')
                ->label('Send OTP')
                ->action(fn () => $this->sendOtp()),
        ]);
    }

    public function sendOtp(): void
    {
        // Send OTP logic
        ray('send otp');
    }
}

Blade: Then, update your Blade template to call the sendOtp function when the button is clicked and when the component is initialized:

<x-dynamic-component
    :component="$getFieldWrapperView()"
    :field="$field"
>
    <div
        x-data="{
            state: $wire.$entangle('{{ $getStatePath() }}'),
            sendOtp() {
                $wire.mountFormComponentAction('{{ $getStatePath() }}', 'sendOtp')
            }
         }"
        x-init="sendOtp"
    >
        <input x-model="state" type="text" maxlength="6" minlength="6" placeholder="000000">

        <button type="button" @click="sendOtp">
            Send OTP
        </button>
    </div>
</x-dynamic-component>

<x-dynamic-component
    :component="$getFieldWrapperView()"
    :field="$field"
>
    <div
        x-data="{
            state: $wire.$entangle('{{ $getStatePath() }}'),
            sendOtp() {
                $wire.mountFormComponentAction('{{ $getStatePath() }}', 'sendOtp')
            }
         }"
        x-init="sendOtp"
    >
        <input x-model="state" type="text" maxlength="6" minlength="6" placeholder="000000">

        <button type="button" @click="sendOtp">
            Send OTP
        </button>
    </div>
</x-dynamic-component>

With these changes, the sendOtp function will be called both when the component is rendered initially and when the button is clicked.
