ParenthesisWPBundle

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 parenthesis/wp-bundle into Symfony's project

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

"repositories": [
        {
            "type": "git",
            "url": "https://github.com/parenthesislab/ParenthesisWPBundle"
        }
    ],
"require": {
    ...
    "parenthesis/wp-bundle": "dev-master"
},

Run php composer.phar update parenthesis/wp-bundle

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

<?php
    public function registerBundles()
    {
        $bundles = array(
            ...
            new Parenthesis\WPBundle\ParenthesisWPBundle(),
        );

        ...

        return $bundles;
    }

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

...
parenthesis_wp:
    resource: "@ParenthesisWPBundle/Resources/config/routing.xml"

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

parenthesis_wp:
    globals: # If you have some custom global variables that WordPress needs
        - wp_global_variable_1
        - wp_global_variable_2
    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())
    enable_wordpress_listener: false # If you want to disable the WordPress request listener
    security:
        firewall_name: "secured_area" # This is the firewall default name
        login_url: "/wp-login.php" # Absolute URL to the wordpress login page

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: Parenthesis\WPBundle\Entity\User, property: login }

    # Example firewall for an area within a Symfony application protected by a WordPress login
    firewalls:
        secured_area:
            pattern:    ^/admin
            access_denied_handler: parenthesis.wp.security.entry_point
            entry_point: parenthesis.wp.security.entry_point
            anonymous: ~

    access_control:
        - { path: ^/admin, roles: ROLE_WP_ADMINISTRATOR }

3) Wrap code inside web/app.php and web/app_dev.php

To avoid problem with some Wordpress plugin, you need to wrap code inside a function like this :

<?php
use Symfony\Component\HttpFoundation\Request;

// change for app_dev.php
function run(){
    $loader = require_once __DIR__.'/../var/bootstrap.php.cache';

    require_once __DIR__.'/../app/AppKernel.php';

    $kernel = new AppKernel('dev', true);
    $kernel->loadClassCache();
    Request::enableHttpMethodParameterOverride();
    $request = Request::createFromGlobals();
    $response = $kernel->handle($request);
    $response->send();
    $kernel->terminate($request, $response);
}
run();

And now do the same for app.php

4) 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/var/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();
}

symfony($sfContainer);

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

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

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

Put the following rules:

DirectoryIndex index.php
IndexIgnore /symfony

<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
parenthesis.wp.manager.comment	Wordpress comment manager
parenthesis.wp.manager.comment_meta	Wordpress comment metas manager
parenthesis.wp.manager.link	Wordpress link manager
parenthesis.wp.manager.option	Wordpress option manager
parenthesis.wp.manager.post	Wordpress post manager
parenthesis.wp.manager.post_meta	Wordpress post metas manager
parenthesis.wp.manager.term	Wordpress term manager
parenthesis.wp.manager.term_relationships	Wordpress term relationships manager
parenthesis.wp.manager.term_taxonomy	Wordpress taxonomy manager
parenthesis.wp.manager.user	Wordpress user manager
parenthesis.wp.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('parenthesis.wp.manager.post');
$userManager = $this->get('parenthesis.wp.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');

Override

Entities

For every Wordpress entities, you can override the default classes. To do so, just add the following configuration in your config.yml (for Post entities):

parenthesis_wp:
    services:
        post:
            class: MyApp\AppBundle\Entity\Post

In order to avoid further troubles when creating a new instance (for example), remember to always use the manager to create a new entity ($container->get('parenthesis.wp.manager.post')->create()).

Managers

You can use your own managers too. To customize it, register yours as services — should be marked as privates — as follow :

parenthesis_wp:
    services:
        comment:
            manager: my_custom_comment_service

Your manager will now be reachable using the usual command, IE from a controller : $this->get('parenthesis.wp.manager.comment')

Repositories

Implementing your custom repository classes is as simple as follow :

parenthesis_wp:
    services:
        comment_meta:
            repository_class: MyApp\MyBundle\Repository\ORM\CustomCommentMetaRepository

Extra

Enable cross application I18n support

If you already have a wordpress plugin to handle I18n, ParenthesisWPBundle 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 :

parenthesis_wp:
    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('parenthesis.wp.i18n_cookie_name');
    }
}

Handling password protected posts

If you use password protected posts and you have defined your own COOKIEHASH constant, you can provide it using the cookie_hash parameter in your config.yml file. You will then be able to use the wp_post_password_required twig function that behave exactly like post_password_required Wordpress function.

Display Wordpress theme into a Symfony Twig-rendered route

You can display the WordPress header (with administration menu bar if available), sidebar and footer into your Symfony's Twig templates by using the following Twig functions available in this bundle:

{{ wp_get_header() }}
{{ wp_get_sidebar() }}

<div id="main">
    Your Twig code comes here
</div>

{{ wp_get_footer() }}
