Tell us what you are trying to do?
I needed to add a comma to my outputted numbers. I followed the directions here for creating a shortcode (https://toolset.com/forums/topic/i-want-to-add-comma-every-three-digits/) and it works beautifully. However, now it outputs a zero if that same number field is blank. It doesn't do that if I don't use this custom shortcode. I imagine there's maybe a line to add to the shortcode php function code so that it doesn't output the zero if the field is blank, but not show how to do this. Any help would be appreciated!

Is there any documentation that you are following?
https://toolset.com/forums/topic/i-want-to-add-comma-every-three-digits/

functions.php code:
add_shortcode( 'ts_format_number', 'ts_format_number_func');
function ts_format_number_func( $atts, $content ) {
$int = (int) do_shortcode($content);
return number_format($int, 2);
}

Shortcode example:
[ts_format_number][types field="price"][/types][/ts_format_number]

With this shortcode, an empty "price" field outputs a zero now.

Hi there,

Please kindly change the first part of the code to:

add_shortcode( 'ts_format_number', 'ts_format_number_func');
function ts_format_number_func( $atts, $content ) {
    $int = (int) do_shortcode($content);
    if ($int == null) {
        return "";
    } else {
        return number_format($int, 0);
    }
    
}

Then, use the shortcode as you would do before.

Thanks.
