Display Content of a post or page anywhere

This is useful if you have a place on the sidebar or a box on the homepage where you want to have some changeable content. Add the content to a post or page and then output it wherever you want it using this.

<?php
// know the id of the page you want to display
$theId = 668;
// get the post
$feature = get_post($theId);
// get the content for the post. You can also get anything else for the post, post_title, post_excerpt...
$content = $feature->post_content;
echo $content;
?>
