Insert content after each posts with filter hook - WordPress

If we want to add some content in single posts, Everyone like to edit single.php file in our theme directory. In almost WordPress themes, this single.php file is used to render single posts.

We just want to add our content after the the_content() function.

Today we are going to use another method to achieve this same functionality. Just copy & paste below code in to our theme’s functions.php file.

function insertFootNote($content) {
	if(!is_feed() && !is_home()) {
			$content.= "<div class='subscribe'>";
			$content.= "<h4>Enjoyed this article?</h4>";
			$content.= "<p>Subscribe to our  <a href='http://feed.example.com'>RSS feed</a> and never miss updates!</p>";
			$content.= "</div>";
	}
	return $content;
}
add_filter ('the_content', 'insertFootNote');

In this code snippet, we just make a new function named as insertFootNote() with our additional content. Then use WordPress filter hook to add this additional content with content from Database.

I always suggest you to try hacks & code snippet as much as possible in different ways. It will improve our knowledge & help to master in our domain.
