I can't figure out the other myself... I am not able to evaluate if the mulitday checkbox is checked or not. And the value that is returned always says array rather then 0 or 1.
function func_format_2nd_date_price( $atts ) {
global $post;
if ( get_post_meta($post->ID,'wpcf-multi-day',true) != 0) {
$multi = get_post_meta($post->ID,'wpcf-multi-day',true);
echo "Is Multi " . $multi;
}
}
add_shortcode('format_2nd_date_price', 'func_format_2nd_date_price');
In addition I noticed something odd...
If a - minus/hyphen is placed between two shortcodes it becomes an – en-dash in the popup.
