Post Share Count

How to add html wrapper or some css class to counter and/or display counter as link?

Use array as argument with keys before_ and after_ prefix and social link name, here is example how to add @via parameter twitter sharing link:

<?php
$share_args = array(
    'before_twitter' => '<span class="share-link"><a href="https://twitter.com/intent/tweet?text=' . urlencode(get_the_title()) . '&url=' . urlencode(get_permalink()) . '&via=' . urlencode('your-twitter-name') . '" rel="nofollow" target="_blank"><span class="genericon genericon-twitter"></span> ',
    'after_twitter' => '</a></span>',
);
the_post_share_count( $share_args );
?>

Also you can add changes to functions.php:
function your_theme_post_share_count_services( $services ) {
$services[‘twitter’][‘before’] = ‘ ‘;
return $services;
}
add_filter(‘post_share_count_services’, ‘your_theme_post_share_count_services’);

How to limit list of social networks? (or “I want only twitter counter”)

Add show_only parameter:
array( ‘twitter’, ‘facebook’ ));
the_post_share_count($args);
?>

Also you can do it in functions.php:
function your_theme_post_share_count_services( $services ) {
unset( $services[‘facebook’] );
unset( $services[‘pinterest’] );
unset( $services[‘googleplus’] );
unset( $services[‘linkedin’] );
return $services;
}
add_filter(‘post_share_count_services’, ‘your_theme_post_share_count_services’);
