Introduction

The TastyIgniter translate extension provides comprehensive multilingual support. It allows administrators to manage translations for dynamic content (models), and frontend users to choose their preferred language.

Features

• Locale Picker: Allow admin and frontend users to choose their preferred language.
• Dynamic Content Translation: Translate dynamic content such as database records.
• Locale Picker Component: Allow visitors to choose their preferred language.

Installation

You can install the extension via composer using the following command:

composer require tastyigniter/ti-ext-translate:"^4.0" -W

Run the database migrations to create the required tables:

php artisan igniter:up

Usage

Configuring default locale

The setLocale method on the translator.localization service is used to set the language of your TastyIgniter application. The getLocale method on the translator.localization service is used to get the current language. You will typically set the default locale within a middleware.

Here is an example of setting the default locale to fr:

resolve('translator.localization')->setLocale('fr');

For more information on making your site multilingual, see the Localization section of the TastyIgniter documentation.

Switching locales

Visitors as well as administrators can choose their preferred language, which will change the language of the frontend or admin pages depending on the selection.

Admin area

In the admin area, you can switch the language by selecting the desired language from the dropdown on the staff profile page. Navigate to Manage > Staff members > Edit Staff and select the desired language from the Language dropdown. The admin area will be displayed in the selected language.

The Igniter\Flame\Translation\Middleware\Localization middleware is used to set the language of the admin area. The middleware checks if the staff member has a language set in their profile and sets the language accordingly.

Frontend

To allow visitors to switch the language, you can create a component to show a dropdown with the available languages. The component will change the language of the page depending on the selection. Here is an example creating a language picker livewire component:

use Igniter\System\Models\Language;
use Livewire\Component;

class LocalePicker extends Component
{
    public function render()
    {
        return view('localepicker', [
            'locales' => Language::listSupported(),
            'activeLocale' => resolve('translator.localization')->getLocale(),
        ]);
    }

    public function onSwitchLocale($locale)
    {
        resolve('translator.localization')->setLocale($locale);

        return redirect()->back();
    }
}

The listSupported method on the Language model returns an array of supported languages, where the key is the language code and the value is the language name. The getLocale method on the translator.localization service is used to get the current language. The setLocale method on the translator.localization service is used to change the language of the page.

The component view file localepicker.blade.php:

<div>
    <select wire:change="onSwitchLocale($event.target.value)">
        @foreach ($locales as $code => $name)
            <option value="{{ $code }}" {{ $code == $activeLocale ? 'selected' : '' }}>
                {{ $name }}
            </option>
        @endforeach
    </select>
</div>

When a visitor selects a language from the dropdown, the onSwitchLocale method is called, which changes the language of the page and redirects back to the same page.

The Igniter\Flame\Translation\Middleware\Localization middleware is used to set the language of the frontend. The middleware checks does the following checks:

• If the visitor has a language set in the first part of the URL, it sets the language accordingly.
• If the visitor has a language set in their browser, it sets the language accordingly.
• If the visitor has a language set in their session, it sets the language accordingly.
• If the visitor does not have a language set in the above options, it sets the default language.

Model translation

Models can have their attributes translated by using the Igniter\Translate\Actions\TranslatableModel action and specifying which attributes to translate using the translatable method. Here's how you can configure a model to have translatable attributes:

use Igniter\Translate\Actions\TranslatableModel;
use Igniter\Flame\Database\Model;

class Category extends Model
{
    public array $implement = [TranslatableModel::class];

    public function translatable() {
        return ['name'];
    }
}

You can also translate models on other extensions by adding extending the model class within your extension class boot method. Here is an example of how to translate the Category model from the Igniter.Cart extension:

use Igniter\Cart\Models\Category;
use Igniter\Translate\Actions\TranslatableModel;

public function boot()
{
    Category::extend(function ($model) {
        $model->implement[] = TranslatableModel::class;
        $model->addDynamicMethod('translatable', function () {
            return ['name', 'description'];
        });
    });
}

The addDynamicMethod method is used to add a new method to the model class.

Setting translations

You can store translations for the active locale by setting the model attribute value using the model property. Here is an example of setting the name attribute of a Category model to a french translation, assuming the active locale is set to fr:

$category = Category::find(1);
$category->name = 'Nom de la catégorie';
$category->save();

You can store translations for multiple locales when creating a model.

$category = Category::create([
    'name' => [
        'en' => 'Category Name',
        'fr' => 'Nom de la catégorie',
    ],
]);

To store the translation for a specific locale, you can use the setLocale method on the translator.localization service.

resolve('translator.localization')->setLocale('fr');

$category = Category::find(1);
$category->name = 'Nom de la catégorie';
$category->save();

You can store translations for multiple locales when saving a model.

$category = Category::find(1);

$category->name = [
    'en' => 'Category Name',
    'fr' => 'Nom de la catégorie',
];

$category->save();

Retrieving translations

You can retrieve translations for the active locale by accessing the model attribute value. Here is an example of retrieving the name attribute of a Category model, assuming the active locale is set to fr:

$category = Category::find(1);
echo $category->name;

You can retrieve translations for a specific locale by using the getAttributeTranslatedValue method on the model instance.

$category = Category::find(1);

echo $category->getAttributeTranslatedValue('name', 'fr');

Form widgets

Translatable text

The trltext form widget is used to create a text input field that can store translations for multiple locales.

'my_field' => [
    'label' => 'Name',
    'type' => 'trltext',
],

The options for the trltext form widget type are the same as the text form field type.

Translatable textarea

The trltextarea form widget is used to create a textarea input field that can store translations for multiple locales.

'my_field' => [
    'label' => 'Description',
    'type' => 'trltextarea',
],

The options for the trltextarea form widget type are the same as the textarea form field type](https://tastyigniter.com/docs/extend/forms#textarea).

Translatable rich editor

The trlricheditor form widget is used to create a rich text editor input field that can store translations for multiple locales.

'my_field' => [
    'label' => 'Content',
    'type' => 'trlricheditor',
],

The options for the trlricheditor form widget type are the same as the richeditor form widget type.

Translatable markdown editor

The trlmarkdowneditor form widget is used to create a markdown editor input field that can store translations for multiple locales.

'my_field' => [
    'label' => 'Content',
    'type' => 'trlmarkdowneditor',
],

The options for the trlmarkdowneditor form widget type are the same as the markdowneditor form widget type.
