If you want to put custom content after each post just copy the following code and paste it in functions.php file:
function add_post_content($content) {
if(!is_feed() && !is_home()) {
$content .= ‘<p>This article is copyright © ‘.date(‘Y’).’ ’.bloginfo(‘name’).’</p>’;
}
return $content;
}
add_filter(‘the_content’, ‘add_post_content’);
