FBGraph Plugin

The FBGraph Plugin is a Facebook Graph API client for Grav CMS

Installation

Installing the FBGraph plugin can be done in one of two ways. The GPM (Grav Package Manager) installation method enables you to quickly and easily install the plugin with a simple terminal command, while the manual method enables you to do so via a zip file.

GPM Installation (Preferred)

The simplest way to install this plugin is via the Grav Package Manager (GPM) through your system's terminal (also called the command line). From the root of your Grav install type:

bin/gpm install fbgraph

This will install the FBGraph plugin into your /user/plugins directory within Grav. Its files can be found under /your/site/grav/user/plugins/fbgraph.

Manual Installation

To install this plugin, just download the zip version of this repository and unzip it under /your/site/grav/user/plugins. Then, rename the folder to fbgraph. You can find these files on GitHub or via GetGrav.org.

You should now have all the plugin files under

/your/site/grav/user/plugins/fbgraph

NOTE: This plugin is a modular component for Grav which requires Grav and the Error and Problems to operate.

Configuration

Before configuring this plugin, you should copy the user/plugins/fbgraph/fbgraph.yaml to user/config/plugins/fbgraph.yaml and only edit that copy.

Here is the default configuration and an explanation of available options:

enabled: true
route: /fbgraph # endpoint for ajax api requests

host: https://graph.facebook.com/v2.8/
app_id: 1234567890123456 # your app ID
secret: q1w2e3r4t5y6u7i8o9p0a1s2d3 # your secret

resources: # an array of configured resources

Resource configuration

A resource defines an endpoint that you want to request through the graph API. Upon request the resource configuration is transformed into a URL query string. Below is an example of a resource configuration.

...
resources:
    my_photos:
        page_id: me
        edge: /photos
        params:
            type: uploaded
            limit: 10
            fields:
                - source
                - key: images
                  value:
                      - width
                      - height
                      - source

The field parameter defines the fields to be returned from the API. It is possible to define fields for nested resources with the use of key/value pairs. The above configuration will result in the following query string fields=source,images{width,height,source}

Refer to the Facebook Graph API Reference for more information on how to form your queries

Usage

Begin by overriding app_id and secret with the values for your Facebook app

Twig

The following functions are available in your twig template files

fbgraph(array resource) resource is an associative array (or parsed yaml config) The function will send a request to Facebook's API and return the response as parsed JSON

Ajax

All resources configured under plugins.fbgraph.resources can be accessed via the /fbgraph.json endpoint. It accepts the following parameters

resource(required) the name of the resource
before hash for the before cursor (previous page)
after hash for the after cursor (next page)

example http://mygravsite.local.host/fbgraph.json?resource=my_photos&after=MA2ss72UD8g12jbfa
