Filter Plus

[GeneticsPro]

Hello. I propose to improve the "plus" function.

php-liquid/src/Liquid/StandardFilters.php

Line 334 in d3e9c3d

public static function plus($input, $operand)

For the possibility of adding an unlimited number of parameters.
Example:
{{ 4 | plus: 2, 3, 7 }}

Решение:

public static function plus($input, $operand)
{
	//return (float)$input + (float)$operand;

	$args = func_get_args();
	unset($args[0]);

	if ($args)
	{
		$input = (float) $input;

		foreach ($args as $arg)
		{
			if ($arg)
			{
				$input += (float) $arg;
			}
		}

		return $input;
	}
	else
	{
		return $input;
	}
}
