Configuration

Database Migrations

Before usage this extension, we'll also need to prepare the database.

php yii migrate --migrationPath=@vendor/yii2mod/yii2-settings/migrations

Module Setup

To access the module, you need to configure the modules array in your application configuration:

'modules' => [
    'settings' => [
        'class' => 'yii2mod\settings\Module',
    ],
],

You can then access settings management section through the following URL:

http://localhost/path/to/index.php?r=settings

or if you have enabled pretty URLs, you may use the following URL:

http://localhost/path/to/index.php/settings

Component Setup

To use the Setting Component, you need to configure the components array in your application configuration:

'components' => [
    'settings' => [
        'class' => 'yii2mod\settings\components\Settings',
    ],
],

Usage:

$settings = Yii::$app->settings;

$value = $settings->get('section', 'key');

$settings->set('section', 'key', 125.5);

$settings->set('section', 'key', 'false', SettingType::BOOLEAN_TYPE);

// Checking existence of setting
$settings->has('section', 'key');

// Activates a setting
$settings->activate('section', 'key');

// Deactivates a setting
$settings->deactivate('section', 'key');

// Removes a setting
$settings->remove('section', 'key');

// Removes all settings
$settings->removeAll();

// Get's all values in the specific section.
$settings->getAllBySection('section');

$settings->invalidateCache(); // automatically called on set(), remove();

Manage custom settings

You can use your own form model to manage custom settings for your web application via SettingsAction. To use the SettingsAction class you need to follow the following steps:

1. Create your own model, for example:

<?php

namespace app\models\forms;

use Yii;
use yii\base\Model;

class ConfigurationForm extends Model
{
    /**
     * @var string application name
     */
    public $appName;

    /**
     * @var string admin email
     */
    public $adminEmail;

    /**
     * @inheritdoc
     */
    public function rules(): array
    {
        return [
            [['appName', 'adminEmail'], 'required'],
        ];
    }

    /**
     * @inheritdoc
     */
    public function attributeLabels(): array
    {
        return [
            'appName' => Yii::t('app', 'Application Name'),
            'adminEmail' => Yii::t('app', 'Admin Email'),
        ];
    }
}

2. Create view file, named settings.php with the following content:

<?php

use yii\helpers\Html;
use yii\widgets\ActiveForm;

/* @var $model \app\models\forms\ConfigurationForm */
/* @var $this \yii\web\View */

$this->title = Yii::t('app', 'Manage Application Settings');
?>
<?php $form = ActiveForm::begin(); ?>

<?php echo $form->field($model, 'appName'); ?>

<?php echo $form->field($model, 'adminEmail'); ?>

<?php echo Html::submitButton(Yii::t('app', 'Save'), ['class' => 'btn btn-success']) ?>

<?php ActiveForm::end(); ?>

3. Add settings action to your controller class as follows:

<?php

namespace app\controllers;

use yii\web\Controller;

/**
 * Class SiteController
 *
 * @package app\controllers
 */
class SiteController extends Controller
{
    /**
     * @inheritdoc
     */
    public function actions()
    {
        return [
            'manage-settings' => [
                'class' => \yii2mod\settings\actions\SettingsAction::class,
                // also you can use events as follows:
                'on beforeSave' => function ($event) {
                    // your custom code
                },
                'on afterSave' => function ($event) {
                    // your custom code
                },
                'modelClass' => \app\models\forms\ConfigurationForm::class,
            ],
        ];
    }
}

Now you can access to the settings page by the following URL: http://localhost/path/to/index.php?r=site/manage-settings/
