Shopping cart

[lional]

Hi all

I am trying to write a shopping cart that allows for the customer to purchase more than one product in one transaction and then press the buy button.

The code on the products list page is:

<?php
            include 'includes/conn_db.php';
            $query_cl = "SELECT * from products";
$result_cl = mysql_query($query_cl, $conn);
while ($row_cl = mysql_fetch_assoc($result_cl)){
  $prod_id_out = $row_cl["prod_id"];
$description_out = $row_cl["description"];
$size_inch_out = $row_cl["size_inch"];
$size_mm_out = $row_cl["size_mm"];
$price_out = $row_cl["price"];
      
      print <<<PRICES
            <td valign="top">
            <select name="$prod_id_out">
            <option value="0"></option>
            <option value="1">1</option>
            <option value="2">2</option>
            <option value="3">3</option>
            <option value="4">4</option>
            <option value="5">5</option>
            <option value="6">6</option>
            <option value="7">7</option>
            <option value="8">8</option>
            <option value="9">9</option>
            <option value="10">10</option>
            </select></td>
            <td>
            $size_inch_out</td>
            <td>$size_mm_out</td>
            <td>$price_out</td>
            
            
            </tr>
PRICES;
}
?>

and my view cart is:

<?php
            include 'includes/conn_db.php';
            $query_cl = "SELECT * from products";
$result_cl = mysql_query($query_cl, $conn);
while ($row_cl = mysql_fetch_assoc($result_cl)){

  $prod_id_out = $row_cl["prod_id"];
$description_out = $row_cl["description"];
$size_inch_out = $row_cl["size_inch"];
$size_mm_out = $row_cl["size_mm"];
$price_out = $row_cl["price"];
  $final_var = '$' .  $prod_id_out . '_out';
  $post_line = $final_var . ' = $_POST["' . $prod_id_out . '"]';
  eval("\$post_line = \"$post_line\";");
     
  
}

?>

I am having problems with the view cart. I need to find a way to dynamically assing the variables and then I want to check if the value is greater than 0, to add the product to the cart

 

Any help will be appreciated
