Extending settings

Default settings

Back Office provides a default set of ezsettings for admin_group SiteAccess. Keep in mind that those settings might be easily overridden by global or SiteAccess ezsettings, as well as all bundles, including third party and yours. For this reason, ezsettings values mentioned in the documentation might not work in your project.

User settings

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);

namespace App\Setting;

use EzSystems\EzPlatformUser\UserSetting\FormMapperInterface;
use EzSystems\EzPlatformUser\UserSetting\ValueDefinitionInterface;
use eZ\Publish\Core\Base\Exceptions\InvalidArgumentException;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
use Symfony\Component\Form\FormBuilderInterface;

class Unit implements ValueDefinitionInterface, FormMapperInterface
{
    public const METRIC_OPTION = 'metric';
    public const IMPERIAL_OPTION = 'imperial';

    public function getName(): string
    {
        return 'Unit';
    }

    public function getDescription(): string
    {
        return 'Choose between metric and imperial unit systems';
    }

    public function getDisplayValue(string $storageValue): string
    {
        switch($storageValue) {
            case self::METRIC_OPTION:
                return 'Metric';
            case self::IMPERIAL_OPTION:
                return 'Imperial';
            default:
                throw new InvalidArgumentException(

                    sprintf('There is no \'%s\' option', $storageValue)
                );
        }
    }

    public function getDefaultValue(): string
    {
        return 'metric';
    }

    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,
            ]
        );
    }
}

Add new service definitions in config/services.yaml:

1
2
3
4
5
6
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'].

Templates settings

You can define a template to be used when editing the given setting in config/packages/ezplatform.yaml:

1
2
3
4
5
6
7
8
9
ezplatform:
    system:
        admin_group:
            user_settings_update_view:
                full:
                    unit:
                        template: User/Settings/update_unit.html.twig
                        match:
                            Identifier: [ unit ]

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

1

4

{% extends '@ezdesign/account/settings/update.html.twig' %}

{% block form %}
    {{ parent() }}
    <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 %}
