FB – Comment Moderation Tool bug or error in the code?
If it is a page the global post object is already set when wp_head fires. But you have to get the data for this page with custom code. Pseudo code: add_action ( ‘wp_head’, ‘wpse_58539_get_ogp’ ); function wpse_58539_get_ogp() { if ( ! is_page_template( ‘your-template-name’ ) ) { return; } $page = get_post( $GLOBALS[‘post’] ); // Inspect … Read more
