I would like to add a "like" icon at the end of articles. It’s just an icon which allow the reader of the article to click on the icon and increment a counter. It’s not a social button.
For now, i can add this icon directly in page.tpl
<?php print render($page['content']); ?> <p class="like-article-container"><span class="like-article"><span class="glyphicon glyphicon-thumbs-up" aria-hidden="true"></span></span></p>
It works but i was wondering if it was possible to add it directly in the content type "article" in admin without modifying the file.tpl
