$atts = shortcode_atts( array( 'name' => '', 'id' => 0, 'default' => '' ), $atts, 'field' );
$key = sanitize_key( $atts['name'] );
if ( '' === $key || is_protected_meta( $key, 'post' ) ) {
return '';
}
$post_id = $atts['id'] ? absint( $atts['id'] ) : get_the_ID();
if ( ! $post_id || ( ! is_post_publicly_viewable( $post_id ) && ! current_user_can( 'read_post', $post_id ) ) ) {
return '';
}
$value = get_post_meta( $post_id, $key, true );
if ( is_array( $value ) || is_object( $value ) || '' === (string) $value ) {
return esc_html( $atts['default'] );
