Answer 1

对我来说有点专业。我只是用 zencart 打开我的网站http://www.hvgbuilding.com/

Answer 2

您正在比较两个字符串。您需要在money_format检查$cartTotal > $minimum或声明另外两个字符串（“格式化”值）之后转换字符串（）

$cartOutput = "";
$cartTotal = 0;
$minim = 20.00;
$pp_checkout_btn = '';
$product_id_array = '';

setlocale(LC_MONETARY, "en_US");
$cartTotalFormatted = money_format("%10.2n", $cartTotal);
$minimFormatted = money_format("%10.2n", $minim);

// Finish the Checkout Btn
if ($cartTotal > $minim )
{
  $pp_checkout_btn .= ' ';
} else {
  $pp_checkout_btn .= "A minimum of ". $minimFormatted ." is required "; 
}
