Description

FAQ
- Why don’t you support feature X?
-
I wrote this plugin for my own site, NiallKennedy.com, added some slight flexibility through filters, and released the plugin on GitHub as a PHP library with a WordPress plugin wrapper. I use summary cards for my site’s articles. If you would like to add better support for photos, galleries, videos, apps, or products exposed to Twitter you can fork my work and optionally send some code in a pull request.
- How do I add my Twitter account?
-
First you need to hook into the filter from code in your theme or site plugin(s). You can add this code to your theme’s
functions.php
file or create a new file inwp-content/mu-plugins/twitter-cards.php
or something similar.add_filter( 'twitter_cards_properties', 'twitter_custom' );
Next you need to modify the array passed to the filter with your own values.
function twitter_custom( $twitter_card ) { if ( is_array( $twitter_card ) ) { $twitter_card['creator'] = '@niall'; $twitter_card['creator:id'] = '1085'; } return $twitter_card; }
The values generated by the plugin are passed to your new function for manipulation before output.
The Twitter API function users/show is a good way to lookup your account information. Copy the
screen_name
andid_str
tocreator
andcreator:id
array values respectively in your filter function referenced above.
https://api.twitter.com/1/users/show.json?screen_name=niallYour Twitter screenname may change but your Twitter ID will remain the same. Grab both while you are setting up your site to provide Twitter with the best data.
- You forgot to include a trailing slash on meta elements
-
The plugin outputs HTML-style void elements without a trailing slash by default. Add XML-style trailing slashes by returning a value of
xml
on thetwitter_cards_htmlxml
filter.
