Works beautifully! Thank you so much!
Oddly enough the only thing I was even able to get working at the template level is the below. Kept returning either 0 or “expecting integer, received string” error. Regardless, your fix did the trick globally. Much appreciated.
// Different versions of a number
$unformatted = get_field('paid_attendance');
{
$integerValue = str_replace(",", "", $unformatted); // Remove commas from string
$integerValue = intval($integerValue); // Convert from string to integer
$integerValue = number_format($integerValue); // Apply number format
$floatValue = str_replace(",", "", $unformatted); // Remove commas from string
$floatValue = floatval($floatValue); // Convert from string to float
$floatValue = number_format($floatValue, 2); // Apply number format
echo $integerValue; // Output values
}
