Wordpress: include content of one page in another

Question

How do I include the page content of one or more page in another page?

ex. I have pageA, pageB and pageC and I want to include the contents of these pages in pageX

is there a wordpress function that loads the post of a specified page/post?
like show_post("pageA")??

Hi @dany:

There is not a show_post() function per se in WordPress core but it is extremely easy to write:

function show_post($path) {
  $post = get_page_by_path($path);
  $content = apply_filters('the_content', $post->post_content);
  echo $content;
}

Note that this would be called with the page's path, i.e.:

<?php show_post('about');  // Shows the content of the "About" page. ?>
<?php show_post('products/widget1');  // Shows content of the "Products > Widget" page. ?>

Of course I probably wouldn't name a function as generically as show_post() in case WordPress core adds a same-named function in the future. Your choice though.

Also, and no slight meant to @kevtrout because I know he is very good, consider posting your WordPress questions on StackOverflow's sister site WordPress Answers in the future. There's a much higher percentage of WordPress enthusiasts answering questions over there.

Hope this helps.

Kit Johnson's wordpress forum solution with creating a shortcode works, but adds the inserted page in the top of the new page, not where the shortcode was added. Close though, and may work for other people.

from the wordpress post, I pieced together this which inserts the page where the shortcode is put:

function get_post_page_content( $atts ) {
    extract( shortcode_atts( array(
        'id' => null,
        'title' => false,
    ), $atts ) );
    $output = "";       

    $the_query = new WP_Query( 'page_id='.$id );
    while ( $the_query->have_posts() ) {
        $the_query->the_post();
            if($title == true){
            $output .= get_the_title();
            }
            $output .= get_the_content();
    }
    wp_reset_postdata();
    return $output;

}

Then, the shortcode bit works as expected. If you don't want the title, title=false does not work, you need to leave title off entirely.
