KayueWordpressBundle

Improved version of the original WordpressBundle. The biggest different is this new KayueWordpressBundle won't load the entire WordPress core, thus all the WordPress template funtions won't be available in your Symfony app. This is also the goal of the bundle; do everything in Symfony's way.

I started that bundle two years ago and the original repository grew somewhat chaotically, so I decided to start fresh with new repositories.

Features

• WordPress authentication (v1.0.0)
• Custom table prefix (v1.0.1)
• WordPress entities (v1.0.2)
• Multisite support (v1.1.0)
• Twig extension (v1.1.0)
• WordPress style shortcode (v1.1.0)

Todo

• Unit test (please help!)
• Port more WordPress shortcode over
• Refactor blog manager's code

An example to obtain post content, author, comments and categories:

// path/to/controller.php

public function postAction($slug)
{
    $repo = $this->getDoctrine()->getRepository('KayueWordpressBundle:Post');
    $post = $repo->findOneBy(array(
        'slug'   => 'hello-world',
        'type'   => 'post',
        'status' => 'publish',
    ));

    echo $post->getTitle() , "\n";
    echo $post->getUser()->getDisplayName() , "\n";
    echo $post->getContent() , "\n";

    foreach($post->getComments() as $comment) {
        echo $comment->getContent() . "\n";
    }

    foreach($post->getTaxonomies()->filter(function(Taxonomy $tax) {
        // Only return categories, not tags or anything else.
        return 'category' === $tax->getName();
    }) as $tax) {
        echo $tax->getTerm()->getName() . "\n";
    }

    // ...
}

Twig Extension

This bundle comes with the following Twig extensions.

Functions

• wp_switch_blog - equivalent to WordPress's switch_to_blog() method.
• wp_find_attachments_by_post
• wp_find_one_attachment_by_id
• wp_find_featured_image_by_post - equivalent to WordPress's get_the_post_thumbnail method.
• wp_find_post_thumbnail - alias of wp_find_featured_image_by_post
• wp_find_one_option_by_name - equivalent to WordPress's get_option() method.
• wp_find_one_post_by_id
• wp_find_one_post_by_slug
• wp_find_all_metas_by_post - equivalent to WordPress's get_post_meta() method.
• wp_find_one_meta_by - equivalent to WordPress's get_post_meta() method.
• wp_find_metas_by - equivalent to WordPress's get_post_meta() method.
• wp_find_terms_by_post
• wp_find_categories_by_post - equivalent to WordPress's get_categories() method.
• wp_find_tags_by_post - equivalent to WordPress's get_tags() method.

Filters

• wp_texturize - Texturize. Needed for post formatting
• wp_shortcode - equivalent to WordPress's do_shortcode() method.

Multisite

Multisite is a feature of WordPress that allows multiple virtual sites to share a single WordPress installation. In this bundle, each blog (site) has its own entity manager. You need to use blog manager to retrive the blog and then the entity manager.

The following example shows you how to display the latest 10 posts in blog 2.

<?php

public function firstPostAction()
{
    $blogManager = $this->get('kayue_wordpress.blog.manager');
    
    // Method 1: Switch current blog's id. Similar to WordPress's `switch_to_blog()` method.
    // Changing the current blog ID will affect Twig extensions too.
    $blogManager->setCurrentBlogId(2);
    $this->get('kayue_wordpress.post.manager')->findOnePostById(1);

    // Method 2: Use entity manager if you don't want to switch the entire blog.
    // This won't change the current blog ID.
    $anotherBlog = $blogManager->findBlogById(3)->getEntityManager();
    $posts = $anotherBlog->getRepository('KayueWordpressBundle:Post')->findOneById(1);
}

WordPress Authentication

This bundle allow you to create a WordPress login form in Symfony. All you have to do is to configure the WordPress firewall in your security.yml.

The following example demonstrates how to turn AcmeDemoBundle's login form into a WordPress login form.

security:
    
    encoders:
        # Add the WordPress password encoder
        Kayue\WordpressBundle\Entity\User:
            id: kayue_wordpress.security.encoder.phpass

    providers:
        # Add the WordPress user provider
        wordpress:
            entity: { class: Kayue\WordpressBundle\Entity\User, property: username }

    firewalls:
        login:
            pattern:  ^/demo/secured/login$
            security: false
        secured_area:
            pattern:    ^/demo/secured/
            # Add the WordPress firewall. Allow you to read WordPress's login state in Symfony app.
            kayue_wordpress: ~
            # Optional. Symfony's default form login works for WordPress user too.
            form_login:
                 check_path: /demo/secured/login_check
                 login_path: /demo/secured/login
                 default_target_path: /demo/secured/hello/world
            # Optional. Use this to logout.
            logout:
                path:   /demo/secured/logout
                target: /demo/secured/login
            # ...

Shortcode

WordpressBundle support WordPress style shortcode. At the moment the bundle only come with the [caption] shortcode. Pull request is welcome.

To create new shortcode, you need to 1) extends ShortcodeInterface, and then 2) tag it with kayue_wordpress.shortcode

<?php

use Kayue\WordpressBundle\Wordpress\Shortcode\ShortcodeInterface;

class GalleryShortcode implements ShortcodeInterface
{
    public function getName()
    {
        return 'gallery';
    }

    public function($attr, $content = null)
    {
        // do your things...

        return "<p>Return HTML</p>";
    }
}
}

services:
    acme_demo_bundle.wordpress.shortcode.gallery:
        class: Acme\DemoBundle\Wordpress\Shortcode\GalleryShortcode
        tags:
            - { name: kayue_wordpress.shortcode }
