How to Add a Twitter Hashtag with Scriptless Social Sharing

When using Scriptless Social Sharing, you may want to add a site wide hashtag to all of your tweets.

e.g. I might want to add #learnIronCode to all of the tweets created with the Twitter share button.

Before Adding Hashtag

Never use git push force

via @salcode

After Adding Hashtag

Never use git push force #learnIronCode
salferrarello.com/never-git-push-force/
via @salcode

Code to Add

Note The author of Scriptless Social Sharing, Robin Cornett, was kind enough to point out there is an even better way to do this than I had originally posted. I’ve updated this post to use her code.

add_filter( 'scriptlesssocialsharing_twitter_url', function ( $url ) {
    $hashtag = '#myHashTag';
    return str_replace(
        '&url=',
        '%20' . rawurlencode( $hashtag ) . '&url=',
        $url
    );
});
