EkinoWordpressBundle

This bundle is used to bring some Symfony services into Wordpress and manipulates Wordpress using Symfony.

Here are some features:

• Use custom Symfony services into Wordpress,
• Use Symfony to manipulate Wordpress database,
• Create custom Symfony routes out of Wordpress,
• When authenticated on Wordpress, authenticated on Symfony too with correct user roles. (requires ekino-wordpress-symfony Wordpress plugin)
• Catch some Wordpress hooks to be dispatched by Symfony EventDispatcher (requires ekino-wordpress-symfony Wordpress plugin)

Installation

1) Install Symfony into your Wordpress project

Install your Wordpress project and/or get into your root project directory and install symfony like this:

php composer.phar create-project symfony/framework-standard-edition symfony/

2) Install ekino/wordpress-bundle into Symfony's project

After, edit symfony/composer.json file to add this bundle package:

"require": {
    ...
    "ekino/wordpress-bundle": "dev-master"
},

Run php composer.phar update ekino/wordpress-bundle

Then, add the bundle into symfony/app/AppKernel.php:

<?php
    public function registerBundles()
    {
        $bundles = array(
            ...
            new Ekino\WordpressBundle\EkinoWordpressBundle(),
        );

        ...

        return $bundles;
    }

Add the WordpressBundle routing file in your symfony/app/config/routing.yml, after your custom routes to catch all Wordpress routes:

...
ekino_wordpress:
    resource: "@EkinoWordpressBundle/Resources/config/routing.xml"

Optionnally, you can specify the following options in your app/config.yml:

ekino_wordpress:
    table_prefix: wp_ # If you have a specific Wordpress table prefix
    wordpress_directory: /my/wordpress/directory # If you have a specific Wordpress directory structure
    load_twig_extension: true # If you want to enable native WordPress functions (ie : get_option() => wp_get_option())

Also optionally, if you want to use UserHook to authenticate on Symfony, you should add this configuration to your app/security.yml:

security:
    providers:
        main:
            entity: { class: Ekino\WordpressBundle\Entity\User, property: login }

3) Update your Wordpress index.php file to load Symfony libraries

<?php

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Debug\Debug;
use Symfony\Component\DependencyInjection\ContainerInterface;

/**
 * Retrieves or sets the Symfony Dependency Injection container
 *
 * @param ContainerInterface|string $id
 *
 * @return mixed
 */
function symfony($id)
{
    static $container;

    if ($id instanceof ContainerInterface) {
        $container = $id;
        return;
    }

    return $container->get($id);
}

$loader = require_once __DIR__.'/symfony/app/bootstrap.php.cache';

// Load application kernel
require_once __DIR__.'/symfony/app/AppKernel.php';

$sfKernel = new AppKernel('dev', true);
$sfKernel->loadClassCache();
$sfKernel->boot();

// Add Symfony container as a global variable to be used in Wordpress
$sfContainer = $sfKernel->getContainer();

if (true === $sfContainer->getParameter('kernel.debug', false)) {
    Debug::enable();
}

$sfContainer->enterScope('request');

symfony($sfContainer);

$sfRequest = Request::createFromGlobals();
$sfResponse = $sfKernel->handle($sfRequest);
$sfResponse->send();

$sfKernel->terminate($sfRequest, $sfResponse);

4) Edit .htaccess file on your Wordpress root project directory

Put the following rules:

DirectoryIndex index.php

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]

    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^index\.php(/(.*)|$) %{ENV:BASE}/$2 [R=301,L]

    RewriteCond %{REQUEST_FILENAME} -f [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule .? - [L]

    # Rewrite all other queries to the front controller.
    RewriteRule .? %{ENV:BASE}/index.php [L]
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        RedirectMatch 302 ^/$ /index.php/
    </IfModule>
</IfModule>

You're ready to go.

Use in Symfony

You can call Wordpress table managers in Symfony by calling the following services:

Service identifier	Type
ekino.wordpress.manager.comment	Wordpress comment manager
ekino.wordpress.manager.comment_meta	Wordpress comment metas manager
ekino.wordpress.manager.link	Wordpress link manager
ekino.wordpress.manager.option	Wordpress option manager
ekino.wordpress.manager.post	Wordpress post manager
ekino.wordpress.manager.post_meta	Wordpress post metas manager
ekino.wordpress.manager.term	Wordpress term manager
ekino.wordpress.manager.term_relationships	Wordpress term relationships manager
ekino.wordpress.manager.term_taxonomy	Wordpress taxonomy manager
ekino.wordpress.manager.user	Wordpress user manager
ekino.wordpress.manager.user_meta	Wordpress user metas manager

So in custom Symfony controllers, you can create / update / delete data in Wordpress database, like that:

# Here an example that sets user #2 as author for post #1
$postManager = $this->get('ekino.wordpress.manager.post');
$userManager = $this->get('ekino.wordpress.manager.user');

$user = $userManager->find(2);

$post = $postManager->find(1);
$post->setAuthor($user);

$postManager->save($post);

Use in Wordpress

Call a service from Symfony container

Simply use the symfony() method and call your custom service like that:

$service = symfony('my.custom.symfony.service');

Extra

Enable cross application I18n support

If you already have a wordpress plugin to handle I18n, EkinoWordpressBundle allow to persist language toggle between Symfony and wordpress. To do so, just grab the cookie name from the wordpress plugin used and provide its name in the configuration as follow :

ekino_wordpress:
    i18n_cookie_name: pll_language # This value is the one used in "polylang" WP plugin

Also, you can implement your own language switcher in Symfony that work cross application. For instance :

<?php

namespace Acme\DemoBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Cookie;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Request;

class LanguageController extends Controller
{
    /**
     * @param Request $request
     * @param string $locale
     *
     * @return RedirectResponse
     */
    public function toggleLocaleAction(Request $request, $locale)
    {
        $response = new RedirectResponse($this->generateUrl('homepage'));
        $response->headers->setCookie(new Cookie($this->getWpCookieName(), $locale, time() + 31536000, '/', $request->getHost()));

        return $response;
    }

    /**
     * @return string
     */
    protected function getWpCookieName()
    {
        return $this->container->getParameter('ekino.wordpress.i18n_cookie_name');
    }
}
