Social Feed Plugin

The Social Feed Plugin is for Grav CMS. This plugin allows you to easily fetch feeds from Facebook, Twitter and Instagram, and use them in your website, to make a social wall for example.

Installation

Installing the Social Feed 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 social-feed

This will install the Social Feed plugin into your /user/plugins directory within Grav. Its files can be found under /your/site/grav/user/plugins/social-feed.

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 social-feed. 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/social-feed

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

Configuration

Set up apis configuration:

In your dashboard, go to Plugins > Social Feed, and make sure the plugin is enabled. Then, fill out in the form the api informations and usernames to follow regarding to the social network(s) you want to fetch posts from.

Absolute urls:

By default, all images are downloaded in your user folder, in a media subfolder. All media will have a relative url like '/user/media/filename.ext'. If you want absolute urls, set absolute_urls to true in user/config/system.yaml.

Usage

Cli commands :

This plugin offers you a CLI. You must use it to fetch posts locally. In order to do that, after having fully configured the plugin in the dashboard, run in your terminal the following command:

$ bin/plugin social-feed fetch:posts

The better is, in our sense, to make a crontab about it, and let your server update your local feeds itself.

$ crontab -e

Press i, paste the following line for running the script every 15 minutes:

*/15 * * * * php bin/plugin social-feed fetch:posts

Press escape, then enter :x, press enter. It's done.

Twig function:

To get posts from your twig templates, you can use the following function:

{% set postData = socialPosts() %}
<ul>
    {% for post in postData.posts %}
    <li>{{ post.body }}</li>
    {% endfor %}
</ul>

You can even pass parameters to the socialPosts() function:

name type default
order_by string "publishedAt"
order_dir string "DESC"
limit integer 10
page integer 1
usernames array empty
providers array empty

For example:

{%
    set postData = socialPosts({
        order_by: 'provider',
        order_dir: 'ASC',
        limit: 50,
        providers:['facebook', 'twitter']
    })
%}

Api entrypoint:

You can call the api entrypoint '/social-posts', and using the parameters above as query parameters.

For example:

GET /social-posts?order_by=provider&order_dir=ASC&limit=50&providers[]=facebook&providers[]=twitter

This will return a response like this:

{
    "total": 1,
    "limit": 10,
    "page": 1,
    "posts": [
        {
            "provider": "twitter",
            "postId": "794443718241775616",
            "authorUsername": "moduleon",
            "authorName": "moduleon",
            "authorFileUrl": "/user/media/twitter_moduleon.jpeg",
            "headline": "A Todo MVC example of Nucleon is out!\nhttps://t.co/lJEZ4AJbeG",
            "body": "A Todo MVC example of Nucleon is out!\n<a href=\"https://github.com/moduleon/todomvc/tree/develop/examples/nucleon\" target=\"_blank\">https://github.com/moduleon/todomvc/tree/develop/examples/nucleon</a>",
            "fileUrl": null,
            "link": "https://twitter.com/moduleon/status/794443718241775616",
            "publishedAt": "2016-11-04 07:38:37"
        }
    ]
}

Manipulate posts :

Before saving a post internally, the CLI fires the event "onSocialPostBeforeSave". You can listen to it in a custom plugin, manipulate the post attributes, before it to be saved.

<?php

namespace Grav\Plugin;

use Grav\Common\Plugin;
use RocketTheme\Toolbox\Event\Event;

class CustomPlugin extends Plugin
{
    /**
     * Subscribe to app events.
     */
    public static function getSubscribedEvents()
    {
        return [
            'onSocialPostBeforeSave' => ['onSocialPostBeforeSave', 0],
        ];
    }

    /**
     * Pre save callback.
     */
    public function onSocialPostBeforeSave(Event $event)
    {
        $post = event->offsetGet('post');
        $post['myCustomAttribute'] = true;
        $event->offsetSet('post', $post);
    }
}
