Symfony UX TogglePassword

Edit this page

Symfony UX TogglePassword is a Symfony bundle providing visibility toggle for password inputs in Symfony Forms. It is part of the Symfony UX initiative.

It allows visitors to switch the type of password field to text and vice versa.

Installation

Caution

Before you start, make sure you have StimulusBundle configured in your app.

Install the bundle using Composer and Symfony Flex:

1
$ composer require symfony/ux-toggle-password

If you're using WebpackEncore, install your assets and restart Encore (not needed if you're using AssetMapper):

1
2
$ npm install --force
$ npm run watch

Usage with Symfony Forms

Any PasswordType can be transformed into a toggle password field by adding the toggle option:

// ...
use Symfony\Component\Form\Extension\Core\Type\PasswordType;

class CredentialFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            // ...
            ->add('password', PasswordType::class, ['toggle' => true])
            // ...
        ;
    }

    // ...
}

A custom form theme is activated by default, wrapping the widget in <div class="toggle-password-container">. You can disable it by passing use_toggle_form_theme option to false:

class CredentialFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            // ...
            ->add('password', PasswordType::class, ['toggle' => true, 'use_toggle_form_theme' => false])
            // ...
        ;
    }

    // ...
}

Note

Note: If you choose to disable provided package form theme, you will have to handle styling by yourself.

Customizing Labels and Icons

The field uses the words "Show" and "Hide" by default and SVG icons from Heroicons for the toggle button. You can customize them by passing hidden_label, visible_label, hidden_icon and visible_icon options to the field (use null to disable label or icon):

// ...
use Symfony\Component\Form\Extension\Core\Type\PasswordType;

class CredentialFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            // ...
            ->add('password', PasswordType::class, [
                'toggle' => true,
                'hidden_label' => 'Masquer',
                'visible_label' => 'Afficher',
                'visible_icon' => null,
                'hidden_icon' => null,
            ])
            // ...
        ;
    }

    // ...
}

Note

Note: Translation is supported for both label options. You can either use a translation key string (and provide a translation domain with the toggle_translation_domain option) or a Symfony\Component\Translation\TranslatableMessage object. Passing false to the toggle_translation_domain option will disable translation for the labels.

Customizing the Design

The package provides a default stylesheet in order to ease usage. You can disable it to add your own design if you wish.

In assets/controllers.json, disable the default stylesheet by switching the @symfony/ux-toggle-password/dist/style.min.css autoimport to false:

{
    "controllers": {
        "@symfony/ux-toggle-password": {
            "toggle-password": {
                "enabled": true,
                "fetch": "eager",
                "autoimport": {
                    "@symfony/ux-toggle-password/dist/style.min.css": false
                }
            }
        }
    },
    "entrypoints": []
}

Note

Note: you should put the value to false and not remove the line so that Symfony Flex won't try to add the line again in the future.

Once done, the default stylesheet won't be used anymore and you can implement your own CSS on top of the TogglePassword.

You can also only customize specific TogglePassword elements by overriding the default classes. Add your custom class name(s) using the button_classes option for the toggle element. A toggle_container_classes option is also available to customize the container form theme element:

class CredentialFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            // ...
            ->add('password', PasswordType::class, [
                'toggle' => true,
                'button_classes' => ['btn', 'primary', 'my-custom-class'],
                'toggle_container_classes' => ['input-group-text', 'my-custom-container'],
            ])
            // ...
        ;
    }

    // ...
}

Extend the Default Behavior

If you need additional control from JavaScript, you can leverage a few events dispatched by this package:

// assets/controllers/my-toggle-password_controller.js

import { Controller } from '@hotwired/stimulus';

export default class extends Controller {
    connect() {
        this.element.addEventListener('toggle-password:connect', this._onConnect);
        this.element.addEventListener('toggle-password:show', this._onShow);
        this.element.addEventListener('toggle-password:hide', this._onHide);
    }

    disconnect() {
        // You should always remove listeners when the controller is disconnected to avoid side-effects
        this.element.removeEventListener('toggle-password:connect', this._onConnect);
        this.element.removeEventListener('toggle-password:show', this._onShow);
        this.element.removeEventListener('toggle-password:hide', this._onHide);
    }

    _onConnect(event) {
        // The TogglePassword was just created.
        // You can for example add custom attributes to the toggle element
        const toggle = event.detail.button;
        toggle.dataset.customProperty = 'my-custom-value';

        // Or add a custom class to the input element
        const input = event.detail.element;
        input.classList.add('my-custom-class');
    }

    _onShow(event) {
        // The TogglePassword input has just been toggled for text type.
        // You can for example add custom attributes to the toggle element
        const toggle = event.detail.button;
        toggle.dataset.visible = true;

        // Or add a custom class to the input element
        const input = event.detail.element;
        input.classList.add('my-custom-class');
    }

    _onHide(event) {
        // The TogglePassword input has just been toggled for password type.
        // You can for example update custom attributes to the toggle element
        const toggle = event.detail.button;
        delete toggle.dataset.visible;

        // Or remove a custom class to the input element
        const input = event.detail.element;
        input.classList.remove('my-custom-class');
    }
}

Then in your form, add your controller as an HTML attribute:

// ...
use Symfony\Component\Form\Extension\Core\Type\PasswordType;

class CredentialFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            // ...
            ->add('password', PasswordType::class, [
                'toggle' => true,
                'attr' => ['data-controller' => 'my-toggle-password'],
            ])
            // ...
        ;
    }

    // ...
}

Usage without Symfony Forms

You can also use the TogglePassword with native HTML inputs. Inside the stimulus_controller() function you can use the same options to customize labels and icons shown in previous sections:

{# ... #}

{# add "toggle-password-container" or a class that applies "position: relative" to this container #}
<div class="toggle-password-container">
    <label for="password">Password</label>
    <input
        id="password"
        name="password"
        type="password"
        {{ stimulus_controller('symfony/ux-toggle-password/toggle-password', {
            visibleLabel: 'Show password',
            visibleIcon: 'Name of some SVG icon',
            hiddenLabel: 'Hide password',
            hiddenIcon: 'Name of some SVG icon',
            # you can add your own CSS classes if needed, but the following
            # CSS class is required to activate the default styles
            buttonClasses: ['toggle-password-button'],
        }) }}
    >
</div>
