With a few extra lines in my functions.php I've created a shortcode that lets me include the content of a post:

function include_content( $atts ) {
  $id = (int) $atts['id'];
  if ( ! $post = get_post( $id ) )
    return '';
  return apply_filters( 'the_content', $post->post_content );
}
add_shortcode( "include", "include_content" );

Now, if I make a posting like

A few weeks ago I published an epic statement: [include id="345"]

WP generates

<p>A few weeks ago I published an epic statement: <p>FTW!<br />
just my 2 ยข</p>
</p>

So, obviously the content of the old post is wpautop'ed before it's included. If simply returning $post->post_content, that content would end up unrendered (i.e. no <br />) within the outer posting. Now, how can I get rid of the paragraph tags around the imported post, i.e. how can I do the include first and wpautop the whole thing after? Any code improvements are welcome, too!

Thanks!

I suggest you <blockquote> that and maybe even strip_tags() the_content and insert the tag on a new line which should look and feel better, since you're quoting another post. – soulseekah Oct 18 '11 at 5:42
@Soulseekah I'd really like to see it work plain include style. It's not only about quoting. Thanks anyway! – Morgan Oct 18 '11 at 5:57
I really don't see the point in removing the first <p> and the last </p> in an imported post, you either strip all the <p> or not strip the <p>; try to turn this into the filter substr( $post->post_content, 3, -4 ), which answers your initial call for something to "get rid of the paragraph tags around the imported post", you may end up with mismatching <p> tags in several circumstances, and the whole point of markup goes down the drain and you have <p> inside <p>. – soulseekah Oct 18 '11 at 6:04
Of course it's not only about getting rid of the first <p> and the last </p>. Basically I want the content of the old post included first and then the whole thing rendered. – Morgan Oct 18 '11 at 6:23
Insert the shortcode on a line of its own and make sure it's not surrounded by <p> in the HTML editor, that will include your post as is without the extra stuff. Does this solve your problem? – soulseekah Oct 18 '11 at 6:27
