README

Decorates the client and provides the contentful model as an array as defined in the content type of contentful. Additional sugar are the template helper for easy access.

Installation

Step 1: Download the Bundle

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

$ composer require bestit/contentful-bundle

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the app/AppKernel.php file of your project:

<?php
// app/AppKernel.php

// ...
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...

            new BestIt\ContentfulBundle\BestItContentfulBundle(),
        );

        // ...
    }

    // ...
}

Step 3: Configuration Reference

best_it_contentful:

    # This field indicates which controller should be used for the routing.
    controller_field:     controller

    # Which field is used to mark the url of the contentful entry?
    routing_field:        slug

    # This content types have a routable page in the project.
    routable_types:       []
    caching:              # Required
        content:

            # Please provider your service id for caching contentful contents.
            service_id:           ~ # Required

            # Please provide the ttl for your content cache in seconds. 0 means forever.
            cache_time:           0
        routing:

            # Please provider your service id for caching contentful routings.

                        linkContentType:      []
                        unique:               ~

Step 4: Enable the cache reset webhook

Every contentful entry is cached forever with this bundle, but ...

You can use the contentful webhooks to reset your cache entries.

best_it_contentful:
    prefix:   /bestit/contentful
    resource: "@BestItContentfulBundle/Controller"
    type:     annotation

Just add the reset controller to your routing (we suggest to protected it with a http auth password) and input this url in your contentful webhook config and you are ready to go.

The most simple cache reset is the direct reset on an id or the array of the ids from an collection (used as cache tags).

If you have cache entries which are not matched to the entry ids directly but to your own custom cache ids, you need to fill the config value caching.collection_consumer with this custom cache ids to reset them anytime another cache is reset.

Usage

Contentmodel Creator

$php bin/console contentful:create-types`

This command copies your configured content-types in your contentful project.

Client Decorator

<?php

/** @var \BestIt\ContentfulBundle\Service\Delivery\ClientDecorator $clientDecorator */
$clientDecorator = $this->getClient();

$contentType = 'example-type';
$limit = 5;
$where = ['fields.example-slug' => 'example-com'];

if (is_scalar($where)) {
    $entry = $clientDecorator->getEntry($id = $where);
} else {
    $entries = $clientDecorator->getEntries(
        function (\Contentful\Delivery\Query $query) use ($contentType, $limit, $where) {
            $query->setContentType($contentType);

            if ($limit) {
                $query->setLimit($limit);
            }

            array_walk($where, function ($value, $key) use ($query) {
                $query->where($key, $value);
            });

            return $query;
        },
        $cacheId = sha1(__METHOD__ . ':' . $contentType . ':' . serialize($where))
    );
}

Router

We provide you with a router if you want to match contentful elements directly through the url to a controller action of your app. Just register our Slug-Matcher with your CMF-Routing-Chain

You may choose between the caching Slug-Matcher with this service declaration:

services: 
 app.router.contentful:
     class: BestIt\ContentfulBundle\Routing\CachingContentfulSlugMatcher
     public: false
     arguments:
         - '@best_it_contentful.cache.pool.routing'
         - '@contentful.delivery.contentful_client'
         - '%best_it_contentful.controller_field%'
         - '%best_it_contentful.routing_field%'
         - '@best_it_contentful.routing.route_collection_response_parser'
         - '@best_it_contentful.delivery.response_parser'
         - '%best_it_contentful.cache.parameter_against_routing_cache%'
     calls:
         - [setRoutableTypes, ['%best_it_contentful.routable_types%']]
     tags:
         - { name: router, priority: 0 }  # Adjusted to not override the manual routing done by Symfony

Or the non caching Slug-Matcher:

services: 
    app.router.contentful:
        class: BestIt\ContentfulBundle\Routing\ContentfulSlugMatcher
        public: false
        arguments:
            - '@best_it_contentful.delivery.client'
            - '%best_it_contentful.controller_field%'
            - '%best_it_contentful.routing_field%'
            - '@best_it_contentful.routing.route_collection_response_parser'
        calls:
            - [setRoutableTypes, ['%best_it_contentful.routable_types%']]
        tags:
            - { name: router, priority: 0 }  # Adjusted to not override the manual routing done by Symfony

Note that the CachingContentfulSlugMatcher passes the data to your controller as an array, while the non caching ContentfulSlugMatcher passes contentfuls Entry

View-Helper

You can use following twig helper for easier access:

1. get_contentful: Loads an entry/entries matching your query and returns it. If you load entries, you need to save the result array.
2. parseMarkdown: This view helper makes use of Parsedown and returns the markdown of contentful as html.
