PHP - Empty Cart Problem On Paypal Sandbox

I have a site with a shopping cart that uses a paypal buy now button.  The button seems to work fine, when I click it everything in my cart on my site shows up how its suppose to in the paypal checkout page.  Then problem is when I try to log into my buyer sandbox account.  It's telling me its the wrong email or password when I know for a fact it is correct.  I know I need to be logged in to the sandbox developer account while using it, but it still wont let me log in.  My site tried to do multiple items using the value _cart for the cmd hidden paypal input and upload.  However when I use another example that only does one item at a time and has preset variables my sandbox paypal accoung logs in fine.  This makes me think there is something wrong with my code.

Here is the code to build my paypal button for my site
Code: [Select]
$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"  accept-charset="utf-8">
    <input type="hidden" name="cmd" value="_cart">
    <input type="hidden" name="upload" value="1">
    <input type="hidden" name="business" value="pwang@sofpower.com">';
        // Start the For Each loop
        $i = 0;
    foreach ($_SESSION["cart_array"] as $each_item) {
                $item_id = $each_item['item_id'];
                $query = "SELECT * FROM product WHERE id='$item_id' LIMIT 1";
                $result = $db_obj->query($query);
        if($db_obj->error) exit ($db_obj->error);
                //$sql = mysql_query("SELECT * FROM products WHERE id='$item_id' LIMIT 1");
                while ($row = $result->fetch_array(MYSQLI_ASSOC)) {
                        $product_name = $row["product_name"];
                        $price = $row["price"];
                        $details = $row["details"];
                }
                $pricetotal = $price * $each_item['quantity'];
                $cartTotal = $pricetotal + $cartTotal;
                $_SESSION["cart"] = $cartTotal;
                setlocale(LC_MONETARY, "en_US");
        //$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 . '">

                $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>';

                $i++;
    }
        setlocale(LC_MONETARY, "en_US");

        $cartTotal = "<div style='font-size:18px; margin-top:12px;' align='right'>Cart Total : ".$cartTotal." USD</div>";

  // Finish the Paypal Checkout Btn

I'm working on an upload script which will upload my Shopping Cart to Paypal.
I've not worked with this kind of thing before and have no idea where to put this question.

Does anyone know of a way to make sure no one messes with the Form Fields so they can't edit the price?

I'm not working with Paypal API or IPN, just form fields which will upload it.  Going off of their code.

I've thought to verify the lowest price and highest price, but I'm not sure how Shopping Cart systems validate things.


The shopping cart I am building is going to offer Coupon Codes and various prices.  Which alters what things can turn out to be.

Hi there.

This forum has been great so far. I got couple of questions answered here.

Now I am working on a PHP web form where Suppliers list their products for customers to buy.

A customer can buy Product 1 from Supplier A and Product 2 from Supplier B and when the customer checks out through Paypal, the payment for Product 1 should go to Suppplier A and similarly the payment for Product 2 should go the Supplier B's email ID.

I thinks its straight forward and How can we do that? Can you please guide me in the right direction.

Thank you!

Hi, i am building a website where users have a choice to buy a subscription to the next level gold, silver, bronze.

Now i have used paypal before for one off payments but i'm finding it to be a problem when i have three seperate buy now buttons

Code: [Select]
<?php
if ($payment_status == "Completed"){

if ($item_name == "Bronze Membership" && $payment_amount == 4.99&&$payment_currency == "USD"){
$update = mysql_query("UPDATE users SET membership = '1' WHERE email = '$payer_email'");
}
if ($item_name == "Silver Membership" && $payment_amount == 9.99&&$payment_currency == "USD"){
$update = mysql_query("UPDATE users SET membership = '2' WHERE email = '$payer_email'");
}
if ($item_name == "Gold Membership" && $payment_amount == 19.99&&$payment_currency == "USD"){
$update = mysql_query("UPDATE users SET membership = '3' WHERE email = '$payer_email'");
}
}
?>

As you can see i am checking that the item name is the correct name aswell as price but in the sandbox it wont work.

Additional info

Hi All,

I am using paypal code which as follows below
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">

<input type="hidden" name="cmd" value="_xclick">
      <input type="hidden" name="business" value="email">
      <input type="hidden" name="item_name" value="productname">
      <input type="hidden" name="currency_code" value="USD">
      <input type="hidden" name="amount" value="<?php echo $totalamount; ?>">
      <input type="image" src="http://www.paypal.com/en_US/i/btn/x-click-but01.gif" name="submit" alt="Make payments with PayPal - it's fast, free and secure!">

</form>

The following are the problems i am facing

1. the page will be redirect to paypal page such that customer having paypal account can pay so how to pay for customers who dont have paypal account.
2. how to get return value after success/failure of payment.
3. it is throwing an error  as shown below

We notice that you are attempting to pay an Indian resident user. The payment you initiated has been blocked. PayPal only facilitates international payments and cannot be used for domestic payments within India. We suggest you find alternative methods to complete the payment. If you believe that the person you attempted to pay is not based in India, please contact PayPal customer support.

Please share your knowledge on above

Hi Friends,
I am not sure i am looking for help here in right category or not.
I am integrating paypal with IPN, (i have done this on many websites and never had this issue before.)

I am testing it on sandbox account.

I have used same class on many projects but never got this issue, please guide me, what can be the reason for this issue.
Need help urgently,

Thanks

I followed tutorial from youtube Code: [Select]
http://www.youtube.com/watch?v=5b3TcoeY7Bsand made shopping cart. Everything is working fine, but there is one part I want to add. I want user to be able to set the quantity of products without going to the cart (user have to be able to enter quantity himself). At the moment I have no idea how to do this, i am still researching this topic, but wanted to try to ask for help from the pros  . This is the complete code (a bit large):

index.php:
Code: [Select]
<?php
session_start();
require("includes/connection.php");
if(isset($_GET['page'])){

$pages=array("products", "cart");

if(in_array($_GET['page'], $pages)) {

$_page=$_GET['page'];

}else{

$_page="products";

}

}else{

$_page="products";

}

Hello,

I am relatively new to PHP/MySQL (two months) and this is my first post in the forum.

I am trying to implement an 'add to cart' script from http://v3.thewatchmakerproject.com/journal/276/.

The demo works fine but when i implement it on my site i get this  warning: "Assigning the return value of new by reference is deprecated" from what i assume is this Function below:

Can anyone help me? Also, i'm aware that using global is not the done thing anymore, so could somebody explain to me what i should do instead of global.

Thanks in advance,

Code: [Select]
function showCart() {
global $db;
$cart = $_SESSION['cart'];
if ($cart) {
$items = explode(',',$cart);
$contents = array();
foreach ($items as $item) {
$contents[$item] = (isset($contents[$item])) ? $contents[$item] + 1 : 1;
}
$output[] = '<form action="cart.php?action=update" method="post" id="cart">';
$output[] = '<table>';
foreach ($contents as $id=>$qty) {
$sql = 'SELECT * FROM collection WHERE dress_id = '.$id;
$result = $db->query($sql);
$row = $result->fetch();
extract($row);
$output[] = '<tr>';
$output[] = '<td><a href="cart.php?action=delete&id='.$id.'" class="r">Remove</a></td>';
$output[] = '<td>'.$title.' by '.$author.'</td>';
$output[] = '<td>&pound;'.$price.'</td>';
$output[] = '<td><input type="text" name="qty'.$id.'" value="'.$qty.'" size="3" maxlength="3" /></td>';
$output[] = '<td>&pound;'.($price * $qty).'</td>';
$total += $price * $qty;
$output[] = '</tr>';
}
$output[] = '</table>';
$output[] = '<p>Grand total: <strong>&pound;'.$total.'</strong></p>';
$output[] = '<div><button type="submit">Update cart</button></div>';
$output[] = '</form>';
} else {
$output[] = '<p>You shopping cart is empty.</p>';
}
return join('',$output);
}

Hi,

I am using a $_SESSION for my shopping cart but cannot figure out how to total my quantity.

The format I am using is:  $_SESSION['cart']['itemid']['qty']

I realise that i could write a for loop to start at item id 0 and end at 1000 each time totalling the qty field but there must be a better, more efficient way,

Does anybody have any advice?

Hi there, i follow a tutorial from www.phpwebcommerce.com and i'm having path problem for 'add to cart' button.

Demo from phpwebcommerce: http://www.phpwebcommerce.com/plaincart/index.php
I have modified some changes, i'm putting the 'add to cart' button to 1st level instead of 2nd level. Example, under all category (car & manga) i choose car, then inside car category list there is a 'add to cart' button under all car product  instead of clicking inside and show 'add to cart' button.

productDetail.php:
Code: [Select]
<?php
if (!defined('WEB_ROOT')) {
exit;
}

$product = getProductDetail($pdId, $catId);

// we have $pd_name, $pd_price, $pd_description, $pd_image, $cart_url
extract($product);
?>
<table width="100%" border="0" cellspacing="0" cellpadding="10">
 <tr>
  <td align="center"><img src="<?php echo $pd_image; ?>" border="0" alt="<?php echo $pd_name; ?>" width="230" height="170"></td>
  <td valign="middle">
<strong><?php echo $pd_name; ?></strong><br>
Price : <?php echo displayAmount($pd_price); ?><br>
<?php
// if we still have this product in stock
// show the 'Add to cart' button
if ($pd_qty > 0) {
?>
<input type="button" name="btnAddToCart" value="Add To Cart &gt;" onClick="window.location.href='<?php echo $cart_url; ?>';" class="addToCartButton">
<?php
} else {
echo 'Out Of Stock';
}
?>
  </td>
 </tr>
 <tr align="left">
  <td colspan="2"><?php echo $pd_description; ?></td>
 </tr>
</table>

I copy this code out from productDetail.php:
Code: [Select]
<input type="button" name="btnAddToCart" value="Add To Cart &gt;" onClick="window.location.href='<?php echo $cart_url; ?>';">


productList.php:
Code: [Select]

if (!defined('WEB_ROOT')) {
exit;
}

$productsPerRow = 2;
$productsPerPage = 8;

//$productList    = getProductList($catId);
$children = array_merge(array($catId), getChildCategories(NULL, $catId));
$children = ' (' . implode(', ', $children) . ')';

$sql = "SELECT pd_id, pd_name, pd_price, pd_thumbnail, pd_qty, c.cat_id

$result     = dbQuery(getPagingQuery($sql, $productsPerPage));
$pagingLink = getPagingLink($sql, $productsPerPage, "c=$catId");
$numProduct = dbNumRows($result);

// the product images are arranged in a table. to make sure

extract($row);

}

if ($i % $productsPerRow == 0) {
echo '<tr>';

$pd_price = displayAmount($pd_price);

// if the product is no longer in stock, tell the customer
if ($pd_qty <= 0) {
echo "<br>Out Of Stock";
}

echo "</td>\r\n";

if ($i % $productsPerRow == $productsPerRow - 1) {
echo '</tr>';
}

$i += 1;
}

if ($i % $productsPerRow > 0) {
echo '<td colspan="' . ($productsPerRow - ($i % $productsPerRow)) . '">&nbsp;</td>';
}

} else {
?>
<tr><td width="100%" align="center" valign="center">No products in this category</td></tr>
<?php
}
?>
</table>
<p align="center"><?php echo $pagingLink; ?></p>

The code i copy from productDetail.php i paste in productList.php at line48, it show the 'add to cart' button but when i click on it, it cant add to my shopping cart and it show error:

Notice: Undefined variable: cart_url in C:\Domains\xxxxxxxx\wwwroot\xxxxxxxx\plaincart\include\productList.php on line 48
