So, you want to pull content from one page into another...maybe you have an "upcoming events" section that you want to be its own page, yet you also want to show on another page. This shortcode will help you do that. Put this code in your functions.php file.

Pull content from any page given the slug, WordPress shortcode

<?php
// [page name="contact"]
function page_content($atts) {
    	extract(shortcode_atts(array(
			'name' => ''
        ), $atts));
		$return = '';
		$args=array(
		  'name' => $name,
		  'post_type' => 'page',
		  'post_status' => 'publish',
		  'numberposts' => 1
		);
		$thepages = get_posts($args);
		foreach ($thepages as $thepage) {
			$return .= apply_filters('the_content',$thepage->post_content);
		}
		return $return;
}
add_shortcode("page", "page_content");
// end shortcode
?>
