下面是一个示例shortcode 根据id 和type 属性

[post type="content" id="2"]

[post type="title" id="2"]

echo do_shortcode ( \'[post type="content" id="294"]\' );

echo do_shortcode ( \'[post type="title" id="294"]\' );

// [post type="content" id="2"]
// [post type="title" id="2"]

function post__shortcode( $atts ) {
    $a = shortcode_atts(
        array (
            \'id\'   => false,
            \'type\' => "content",
        ), $atts );

    $id   = $a [ \'id\' ];
    $type = $a [ \'type\' ];

    // bad id
    if ( ! is_numeric( $id ) ) {
        return \'\';
    }

    // find the post
    $post = get_post( $id );

    // bad post
    if ( ! $post ) {
        return \'\';
    }

    // allow for other post attributes
    switch ( $type ) {

        case "content":
            return $id === get_the_ID() || $id === get_queried_object_id()
                ? \'\' // no recursive loops!
                : apply_filters( \'the_content\', $post->post_content );

        case "title":
            return $post->post_title;
    }

    // nothing to see here
    return \'\';
}

add_shortcode( \'post\', \'post__shortcode\' );
