Error Call to undefined function money format

0 votes

Every time I try to run this code there is a message saying:

Fatal error: Call to undefined function money_format()

The lines that have that problem are:

$pricetotal = money_format("%10.2n", $pricetotal);

and

$cartTotal = money_format("%10.2n", $cartTotal);

Can you please explain me the reason why this happens ?

$cartOutput = "";
$cartTotal = "";
$pp_checkout_btn = '';
$product_id_array = '';
if (!isset($_SESSION["cart_array"]) || count($_SESSION["cart_array"]) < 1) {
    $cartOutput = "<h2 align='center'>Your shopping cart is empty</h2>";
} else {
    // Start PayPal Checkout Button
$pp_checkout_btn .= '<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
    <input type="hidden" name="cmd" value="_cart">
    <input type="hidden" name="upload" value="1">
    <input type="hidden" name="business" value="you@youremail.com">';
    // Start the For Each loop
    $i = 0; 
    foreach ($_SESSION["cart_array"] as $each_item) { 
        $item_id = $each_item['item_id'];
        $sql = mysql_query("SELECT * FROM products WHERE id='$item_id' LIMIT 1");
        while ($row = mysql_fetch_array($sql)) {
            $product_name = $row["product_name"];
            $price = $row["price"];
            $details = $row["details"];
        }
        $pricetotal = $price * $each_item['quantity'];
        $cartTotal = $pricetotal + $cartTotal;
        setlocale(LC_MONETARY, "en_US");
        $pricetotal = money_format("%10.2n", $pricetotal);
        // Dynamic Checkout Btn Assembly
        $x = $i + 1;
        $pp_checkout_btn .= '<input type="hidden" name="item_name_' . $x . '" value="' . $product_name . '">
        <input type="hidden" name="amount_' . $x . '" value="' . $price . '">
        <input type="hidden" name="quantity_' . $x . '" value="' . $each_item['quantity'] . '">  ';
        // Create the product array variable
        $product_id_array .= "$item_id-".$each_item['quantity'].","; 
        // Dynamic table row assembly
        $cartOutput .= "<tr>";
        $cartOutput .= '<td><a href="product.php?id=' . $item_id . '">' .     $product_name . '</a><br /><img src="inventory_images/' . $item_id . '.jpg" alt="' . $product_name. '" width="40" height="52" border="1" /></td>';

    </form></td>';
    //$cartOutput .= '<td>' . $each_item['quantity'] . '</td>';
    $cartOutput .= '<td>' . $pricetotal . '</td>';
    $cartOutput .= '<td><form action="cart.php" method="post"><input name="deleteBtn' . $item_id . '" type="submit" value="X" /><input name="index_to_remove" type="hidden" value="' . $i . '" /></form></td>';

    $i++; 
} 
setlocale(LC_MONETARY, "en_US");
$cartTotal = money_format("%10.2n", $cartTotal);
$cartTotal = "<div style='font-size:18px; margin-top:12px;' align='right'>Cart Total : ".$cartTotal." USD</div>";

Hello @kartik,

If you are using windows based system then you will not have this function available.

The function money_format() is only defined if the system has strfmon capabilities. For example, Windows does not, so money_format() is undefined in Windows.

Hope it helps!!
