README

Adds social media sharing fields to Silverstripe sites.

Description

This module adds social media meta tags for OpenGraph (Facebook) and Twitter to SiteTree and child page types. It also provides Title, Description and Image fields in the CMS to allow the default values to be overridden.

The module will look for Title, Description and Image values in the following order:

1. As entered in the fields of the provided "Social Media Sharing" section in the CMS.
2. The value of a specific field for a specific class, as configured in the YML (see below).
3. The value of the appropriate field from the CMS "Metadata" section.
4. The value from the "default" field, as specified in the module config. e.g. Page "Title" and "Content".

The module uses placeholder (and field description) text to indicate what values are being used, allowing you to then override them, only if necessary.

Supported social media meta tags include:

• OpenGraph (Facebook)
  • og:site_name
  • og:title
  • og:image
  • og:description
  • og:url
• Twitter
  • twitter:site
  • twitter:title
  • twitter:image
  • twitter:description
  • twitter:card

Requirements

SilverStripe 4.2+

Installation

1. composer require purplespider/silverstripe-basic-social-sharing ^1.0
2. run a /dev/build?flush=all
3. Without any configuration, the module will begin rendering social media meta tags for all page types.
4. Customise these on a per page/DO basis via the new "Social Media Sharing" section, below the existing "Metadata" section for pages.

Defaults

By default, the module will use the following fields to populate the meta tags:

• og:type --> "website"
• og:site_name --> SiteConfig.Title
• og:title --> Title
• og:description --> Content
• og:url --> AbsoluteLink()
• twitter:title --> Title
• twitter:description --> Content
• twitter:card --> "summary"

NOTE: twitter:card will be set to "summary" by default, unless an image field is used. If an image field is used, the content will be set to "summary_large_image".

Adding social media meta tags to DataObjects

By default, this module will only add social media meta tags to SiteTree objects.

To add social media meta tags to DataObjects:

• in _config/config.yml, add the extension to each DataObject class you wish:

Fully\Namespaced\Dataobject:
  extensions:
    - PurpleSpider\BasicSocialSharing\BasicSocialSharingExtension

• in _config/config.yml, set options for titles, descriptions, and images (if desired) for your class.
  • for an example, see the above example config.yml.
• in your DataObject's class, add new fields in getCMSFields():

  public function getCMSFields() {
      $fields = parent::getCMSFields();
      
      ...
      
      $fields->addFieldToTab('Root.Main', new TextareaField("SocialMetaDescription"));
      $fields->addFieldToTab('Root.Main', new UploadField("SocialMetaImage"));
      
      return $fields;
  }

• run a /dev/build?flush=all
