README

Languages for a WebX UI site: the list a site is published in, translated Eloquent attributes, and the dictionary the admin panel is drawn from.

A service library with no section of its own — like webx-ui/seo, it is what the modules that do have sections are built on.

Two problems, kept apart

Mixing these is how a project ends up with translation files nobody can find:

	Interface phrases	Content
Written by	whoever wrote the module	whoever runs the site
Changes	at deploy	all day
How many	a finite list of keys	as much as there is
Lives in	`lang/` in the package	the database

One file of phrases per module, shared by both halves of it; one language map per translatable column. Neither knows about the other.

Install

composer require webx-ui/localization
php artisan migrate
php artisan webx:locales:seed

The languages

use WebxUi\Localization\Locales;

$locales = app(Locales::class);

$locales->codes();        // ['uk', 'ru']
$locales->defaultCode();  // 'uk'
$locales->current();      // the language this request is being answered in
$locales->use('ru');      // false if the site does not publish in it

They live in the locales table so that adding one is a thing somebody does in the panel rather than a deploy. config/webx-localization.php names the set a fresh installation starts with, and is also the answer while the table does not exist yet — the first migrate runs through code that wants a language long before there is one to read.

Translated attributes

A model says which of its columns hold a language map:

use WebxUi\Localization\HasTranslations;

class Page extends Model
{
    use HasTranslations;

    public function translatable(): array
    {
        return ['title', 'slug', 'content'];
    }
}

Schema::create('pages', function (Blueprint $table) {
    $table->id();
    $table->translatable('title', 'slug', 'content');   // json, nullable
    $table->boolean('is_published')->default(true);
});

$page->title;                                  // this request's language, then the fallbacks
$page->title = 'Contacts';                     // writes that language, leaves the others alone
$page->forLocale('uk')->title;
$page->getTranslations('title');               // ['en' => 'Contacts', 'uk' => 'Контакти']
$page->setTranslations('title', [...]);        // what a form editing every language posts

Page::whereTranslation('slug', $slug, 'uk')->first();
Page::orderByTranslation('title', 'asc')->get();

Stored as {"en": "Contacts", "uk": "Контакти"}, which is the shape spatie/laravel-translatable uses — data written here is readable by anything that understands that convention.

Serialising gives one language, not all of them: a public page renders in one, and an API for the site should not hand out every translation of everything. The panel asks for the maps explicitly with translationsToArray().

A column that still holds a plain string — a site being converted — reads as the default language's value rather than as nothing, and the next save writes a proper map.

What a JSON column cannot do

It cannot make a slug unique inside a language, and it cannot be indexed without a generated column per language. Uniqueness of an address belongs to the routing table in webx-ui/seo, where it holds across every kind of entity at once instead of one table at a time. whereTranslation() is what validation uses in the meantime.

The panel's own language

The language of the interface belongs to the person, not to the site: somewhere published only in Ukrainian can still be maintained by somebody who wants English menus.

GET  /api/cms/locales              which languages exist — public
GET  /api/cms/translations/{code}  the dictionary for one of them — public
PUT  /api/cms/auth/locale          what this administrator chose

The first two are public because the sign-in screen has to be drawn before there is a session to ask, and because the text of an interface is not a secret.

webx.panel-locale middleware sets the application's language for a panel request — from the signed-in administrator, or failing that from X-Webx-Locale, or failing that from the browser. It matters for more than menus: a 422 carries validation messages, and those are written by the server.

Where the phrases come from

Every package ships lang/<code>/<group>.php and registers it the ordinary Laravel way:

$this->loadTranslationsFrom(__DIR__.'/../lang', 'webx-pages');

__('webx-pages::fields.title') then works on the server, and the same file reaches the browser in the dictionary above — a module translates its strings once and both halves of it speak the same language.

Resolution, in order:

what the site published over the package — lang/vendor/webx-pages/<code>/
the package's own lang/<code>/
the fallback language
the key itself

Step one is how a site adds a language a module never shipped, or disagrees with a word in one it did:

php artisan vendor:publish --tag=webx-pages-lang

The merge is per line rather than per file, so one new key in a release cannot blank out a screen that was translated a year ago.

config('webx-localization.panel') lists the languages the interface may be shown in — a different question from which languages the site publishes, and listed rather than detected, because a language belongs there only once somebody has read the translation.

Caching

The language list and each dictionary are built once and kept. After editing a lang file:

php artisan webx:locales:clear
