问题描述：

I\'m using a theme template and when i try to get post ID it returns the ID of the template not the ID of the actual single post.

the template ID is: 215

the post ID is: 1911

function metavalue() {
global $post;
$meta = get_post_meta($post->ID, \'product_url\', true);
return $meta;
}
add_shortcode(\'url_short\', \'metavalue\');

get_the_ID(); the_id(); $post->ID; will also output 215. i need a way to get the actual single post ID so i can get the custom field value from \'product_url\'.

function metavalue() {
global $wp;
$url = home_url( $wp->request );
$correct_post_id = url_to_postid( $url ); 
$meta = get_post_meta($correct_post_id, \'product_url\', true);
return $meta;
}
add_shortcode(\'url_short\', \'metavalue\');
