Yii2 TranslatableUrlRule
A custom URL rule class for Yii 2 which allows for translated URL rules.
This extension allows you to write URL rules per language. For example, you can have signup
for en
, aanmelden
for nl
and registrieren
for de
.
Because this extension uses normal Yii2 UrlRule objects to build language-specific URL rules, you still have all power that comes with normal Yii URL rules, including URL parameters and regular expressions.
The current language is determined by the Yii::$app->language
parameter. The value of this parameter is used to create and to parse URLs.
This extension does not set the current language parameter. Use codemix/yii2-localeurls for that.
Installation
The preferred way to install this extension is through composer.
Either run
composer require geertw/yii2-translatable-url-rule
or add
"geertw/yii2-translatable-url-rule": "*"
to the require section of your composer.json
file.
Usage
Update your URL rules to use this class and set the patterns per language.
<? $rules = [ [ 'class' => 'geertw\Yii2\TranslatableUrlRule\TranslatableUrlRule', 'patterns' => [ 'en' => '/signup', 'nl' => '/aanmelden', 'de' => '/registrieren', ], 'route' => 'user/signup', ], [ 'class' => 'geertw\Yii2\TranslatableUrlRule\TranslatableUrlRule', 'patterns' => [ 'en' => '/user/<username>', 'nl' => '/gebruiker/<username>', 'de' => '/benutzer/<username>', ], 'route' => 'user/view', ], ]; ?>
The route
parameter remains the same for all rules. patterns
is an array of all patterns, the key must equal the Yii language identifier.
If there is no pattern for a language, the first configured pattern will be used.
Set forceRuleSearch
to true
to force searching in all rule patterns.
You may omit the class
configuration in your URL rules when you configure a ruleConfig in UrlManager:
<? return [ 'components' => [ 'urlManager' => [ 'ruleConfig' => [ 'class' => 'geertw\Yii2\TranslatableUrlRule\TranslatableUrlRule' ], 'rules' => $rules, // Additional UrlManager configuration ], ]; ?>
Language switcher example
Due to the way this library works, you need to specify two language parameters when creating URLs for routes in another language.
The following two code snippets allow you to create a simple dropdown which allows users to select alternative languages for the current route:
Create a widget like this:
<?php namespace frontend\components; use Yii; use yii\bootstrap\Dropdown; class LanguageSwitcher extends Dropdown { public $langLabels; private $isError; public function init() { $route = Yii::$app->controller->route; $params = $_GET; $this->isError = $route === Yii::$app->errorHandler->errorAction; array_unshift($params, '/' . $route); foreach (Yii::$app->urlManager->languages as $language) { $isWildcard = substr($language, -2) === '-*'; if ($isWildcard) { $language = substr($language, 0, 2); } $params['language'] = $language; $params['url-language'] = $language; $this->items[] = [ 'label' => $this->label($language), 'url' => $params, ]; } parent::init(); } public function run() { // Only show this widget if we're not on the error page if ($this->isError) { return ''; } else { return parent::run(); } } public function label($code) { return isset($this->langLabels[$code]) ? $this->langLabels[$code] : null; } }
Insert the following code in your view code:
<?= LanguageSwitcher::widget([ 'options' => ['class' => 'pull-right'], 'langLabels' => [ 'de' => 'German', 'en' => 'English', 'nl' => 'Nederlands', ], ]) ?>
You might recognize this example, as it is largely based on the example for yii2-localeurls.
