    Hello, I’m just starting to play with filter hooks and in this instance trying to insert some elements after the post text. The problem that I faced is that all text will render after the post content, but the two functions (get_template_part and similar_posts) that I’m calling would actually render before the post content. This is the code that I’m using in functions.php (you can see how it looks at balticgamers.net/1/):

    function insertFootNote($content) {
        if(!is_feed() && !is_home()) {
				//Starting FaceBook button code
				get_template_part( 'template-part-FaceBook-button-bottom' );

				//Starting related articles list
				$content.= "<div id='similar-articles'>";
				$content.= "<strong>Related Posts:</strong>";
				$content.= "<br /><br />";
				similar_posts();
				$content.= "</div>";

				//Starting copyright text
                $content.= "<div id='terms-of-use'>";
                $content.= "<a href='http://balticgamers.com/terms-of-use' title='Terms of use'>© copyright text »</a>";
                $content.= "</div>";
        }
        return $content;
}
add_filter ('the_content', 'insertFootNote');

    Thank you!

    Since both get_template_part() and similar_posts() both seem to echo their results to the screen, you probably need use output buffering to capture the output and append the results of those functions to $content:

    ob_start();
get_template_part( 'template-part-FaceBook-button-bottom' );
$part = ob_get_clean();
$content .= $part;

    Thank You, vtxyzzy !!! That worked!

    At my current knowledge level I would never get to this 🙂

    Thanks again!
