Add user setting

Create new User setting

You can add new preferences to the User Settings menu in the Back Office.

To do so, create a setting class implementing two interfaces: ValueDefinitionInterface and FormMapperInterface.

In this example the class is located in src/Setting/Unit.php and enables the user to select their preference for metric or imperial unit systems.

<?php
declare(strict_types=1);

    {
        return 'Unit';
    }

    public function mapFieldForm(FormBuilderInterface $formBuilder, ValueDefinitionInterface $value): FormBuilderInterface
    {
        $choices = [
            'Metric' => self::METRIC_OPTION,
            'Imperial' => self::IMPERIAL_OPTION,
        ];

        return $formBuilder->create(
            'value',
            ChoiceType::class,
            [
                'multiple' => false,
                'required' => true,
                'label' => $this->getDescription(),
                'choices' => $choices,
            ]
        );
    }
}

Register the setting as a service:

services:
    App\Setting\Unit:
        tags:
            - { name: ezplatform.admin_ui.user_setting.value, identifier: unit, priority: 50 }
            - { name: ezplatform.admin_ui.user_setting.form_mapper, identifier: unit }

You can order the settings in the User menu by setting their priority.

The value of the setting is accessible with ez_user_settings['unit'].

Create template for editing settings

You can override a template used when editing the new setting:

ezplatform:
    system:
        admin_group:
            user_settings_update_view:
                full:
                    unit:
                        template: User/Setting/update_unit.html.twig
                        match:
                            Identifier: [ unit ]

The templates/User/Setting/update_unit.html.twig template must extend the @ezdesign/account/settings/update.html.twig template:

    <div class="alert ez-alert--info mt-4" role="alert">
        Imperial units are: yard, mile, pound, etc.</br>
        Metric units are: meter, kilometer, kilogram, etc.
    </div>
{% endblock %}
