Laravel Package

Overview

Seamless integration of Weglot into your Laravel project.

Requirements

• PHP version 5.5 and later
• Laravel 5.*
• Weglot API Key, starting at free level

Installation

You can install the library via Composer. Run the following command:

composer require weglot/translate-laravel

To use the library, use Composer's autoload:

require_once __DIR__. '/vendor/autoload.php';

Getting Started

Package Register

This package use auto-discovery, when you require it from composer, you should have nothing to do and Provider gonna be added automatically to your config/app.php providers list.

If this doesn't work, you can add our provider to the config/app.php, as following:

return [
    // ...

    'providers' => [
        // ... Other packages ...
        Weglot\Translate\TranslateServiceProvider::class
    ],

    // ...
];

Quick configuration

As usual for Laravel packages, you can publish configuration files by doing:

$ php artisan vendor:publish --provider="Weglot\Translate\TranslateServiceProvider" --tag="config"

You'll find the configuration file in config/weglot-translate.php with default values. If you want to go deeper in configuration, I suggest you to consult the corresponding part of this README.

Configuration

Here is a full configuration file:

<?php

return [
    'api_key' => env('WG_API_KEY'),
    'original_language' => config('app.locale', 'en'),
    'destination_languages' => [
        'fr'
    ],
    'exclude_blocks' => ['.site-name'],
    'exclude_urls' => ['\/admin\/.*'],
    'prefix_path' => '',
    'cache' => false,

    'laravel' => [
        'controller_namespace' => 'App\Http\Controllers',
        'routes_web' => 'routes/web.php'
    ]
];

This is an example of configuration, enter your own API key, your original language and destination languages that you want.

• api_key : is your personal API key. You can get an API Key by signing up on Weglot.
• original_language : original language is the language of your website before translation.
• destination_languages : are the languages that you want your website to be translated into.
• prefix_path : if your laravel installation is not on webroot (ie. something like that: https://my.website.com/foo/ is your actual root) set it to specify the path to your laravel installation
• cache : if you wanna use cache or not. It's not a required field and set as false by default. Look at Caching part for more details.

There is also a non-required parameters:

• exclude_blocks : where you can list all blocks you don't want to be translated. On this example, you can see that all blocks with the site-name class won't be translated.
• exclude_urls : you can prevent urls path from being translated (such as an admin path in this example)

And some Laravel-related parameters:

• laravel.controller_namespace : Used internaly when rewriting routes, change it if your Laravel namespace isn't App or your controllers are moved.
• laravel.routes_web : Used internaly when rewriting routes, refer to the file where you have all your web routes.

Routing

Since we are adding routes for each destination languages we need a strong way to manipulate urls.

We choose to make that through named routes and route() helper.

When you create a route, you have to give a name as following:

Route::get('/', 'Controller@method')
    ->name('my_route_name');

Then you can use it in your blade templates as following:

<a href="{{ route('my_route_name') }}">My link</a>

Like that, we will detect current language and adjust url if needed.

Forcing language

You can force any language as following:

<a href="{{ route('my_route_name', ['_wg_lang' => 'es']) }}">My link</a>

Like that, it will force es language for this link !

Caching

We implemented usage of Cache Facade for our package.

If you wanna use cache, just put the cache parameter to true in this package configuration. It will plug onto the Laravel cache behavior.

If you wanna clear your translation cache, just use the weglot:cache:clear command as following:

$ php artisan weglot:cache:clear

Helper reference

weglotCurrentUrlInstance

One of the core helper of this plugin it returns an instance of Weglot\Util\Url which is what manages:

• Detect current language
• What are translated urls based on current url
• Is a given url translable or not (based on excludedUrls option)
• Generate hreflinks

Here is some usage examples:

$url = weglotCurrentUrlInstance();

// returns current language
$lang = $url->detectCurrentLanguage();

// returns all translated urls
$urls = $url->currentRequestAllUrls();
/**
 * Will return an array like this:
 * Array(
 *   'en' => 'https://weglot.com/',
 *   'fr' => 'https://weglot.com/fr',
 *   'es' => 'https://weglot.com/es',
 *   'de' => 'https://weglot.com/de'
 * )
 **/

// returns a boolean to know if the current url is translable
$translable = $url->isTranslable();

// returns string containing DOM with hreflang tags
$hreflangTags = $url->generateHrefLangsTags();
/**
 * Will return an array like this:
 * <link rel="alternate" href="https://weglot.com" hreflang="en"/>
 * <link rel="alternate" href="https://weglot.com/fr" hreflang="fr"/>
 * <link rel="alternate" href="https://weglot.com/es" hreflang="es"/>
 * <link rel="alternate" href="https://weglot.com/de" hreflang="de"/>
 **/

weglotButtonRender

You can add a language button with the helper function: weglotButtonRender

Two layouts exists:

<!-- first layout -->
{{ weglotButtonRender(1) }}

<!-- second layout -->
{{ weglotButtonRender(2) }}

If you want to overwrite theses templates you can publish them with the following artisan command:

$ php artisan vendor:publish --provider="Weglot\Translate\TranslateServiceProvider" --tag="views"

weglotHrefLangRender

Hreflang links are a way to describe your website and to tell webcrawlers (such as search engines) if this page is available in other languages. More details on Google post about hreflang: https://support.google.com/webmasters/answer/189077

You can add them through the helper function: weglotHrefLangRender

Just put the function at the end of your <head> tag:

<html>
    <head>
        ...

        {{ weglotHrefLangRender() }}
    </head>

weglotLanguage

Simple helper to convert ISO 639-1 code to full language name. It can takes one boolean parameter that allow you to choose having english name or original language name.

Here is a quick example:

$name = weglotLanguage('bg');
// $name will contains: "Bulgarian"

$name = weglotLanguage('bg', false);
// $name will contains: "български"
