setlocale(LC_MONETARY, "en_US");<br /> 
$cartTotal = money_format("%10.2n", $cartTotal);<br /> 
$minim = money_format("%10.2n", $minim);<br /> 


// Finish the Checkout Btn 

if ($cartTotal > $minim)<br />{<br /> 
    $pp_checkout_btn .=<br />'<form> 
    <input type="hidden" name="custom" value="' . $product_id_array . '" accept-charset="UTF-8"> 
    <input type="hidden" name="notify_url" value="https://www.com//.php">

    </form>'; 
}else{<br /> 
    $pp_checkout_btn .= "A minimum of ". $minim ." is required "; 
}

Answer 1

你比較兩個字符串。您需要將字符串（money_format）轉換之後，如果$cartTotal > $minimum檢查或聲明兩個字符串（「格式化」的值）

$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 "; 
}
