Would be nice to be able to pass an additional option parameter to the format() method of CurrencyFormat class. This additional parameter would have the helper wrap NEGATIVE values with a <span> element that can then be styled in a view to show in color, wrapped in parenthesis, etc.

Currently, Blesta wraps the value as follows:

// Wrap the currency code in a span tag

if ($html_wrap_code) {

$value .= ' <span class=\"currency_code\">' . $currency . '</span>';

}

if ($options['html_code']) {

$value = '<span class="currency_value">' . $value . '</span>';

}

I propose an added test for negative value and where the option is set. This would be inserted just above the return $value line:

// value is negative and options['html_wrap_negative'] is true?

if( strpos($value, '-') !== false && $options['html_wrap_negative'] ) {

$value = '<span class="currency_value_negative">' . $value . '</span>';

}

This four-line addition to the format() method allows us to show negative currency values like traditional systems do. By using an added option and a span element with the CSS class name allows others to either take advantage or not.
