    function display_checkout_form()
{
   ?>


<?
global $total_price;
  global $items;
  if(!$items) $items = "0";
  if(!$total_price) $total_price = "0.00";
  ?>
<? if(session_is_registered("admin_user"))
     echo " ";
     else
     echo "<br>Total Items = $items<br>"; 
  ?>
  </td>
  <td align = center rowspan = 2 width = 135>
  <? if(session_is_registered("admin_user"))
     display_button("logout.php", "log-out", "Log Out");
    else
   // display_button("show_cart.php", "view-cart", "View Your Shopping Cart");
  ?>
  </tr>
  <tr>
  <td align = center valign = top>
  <? if(session_is_registered("admin_user"))
       echo " ";
     else

    paypal integration problem

    in PHP Coding Help

    Posted

    Below is the code that displays html and defines many functions. All I need to do is to pass the value of $total_price to the value of amount in the paypal form. This is inside the displaycheckoutform function(I have highlighted in red where the value needs to be passed too). I have also included the form that calls the function to display the checkout page after this initial code. I have tried a few things but am not that experienced and would massively appreciate some help.

     

     

    output.php

    <?

function do_html_header($title = '')
{
  // print an HTML header

  // declare the session variables we want access to inside the function 
  global $total_price;
  global $items;
  if(!$items) $items = "0";
  if(!$total_price) $total_price = "0.00";
?>

    This is the code that runs the script correctly.

     

    Whenever i add any html to the script it produces that error

     

     

    <?session_start();
?>
"><?
  include ('book_sc_fns.php');

      $cart = array();
      session_register("cart");
      $items = 0;
      session_register("items");
      $total_price = "0.00";      
      session_register("total_price");
    }
    if($cart[$new])
      $cart[$new]++;
    else 
      $cart[$new] = 1;
    $total_price = calculate_price($cart);
    $items = calculate_items($cart);

  }
  if($save)
  {
   foreach ($cart as $isbn => $qty)
    {
    if($$isbn=="0")
     unset($cart[$isbn]);
    else 
     $cart[$isbn] = $$isbn;
    }
    $total_price = calculate_price($cart);
    $items = calculate_items($cart);

        {

          $cart = array();

          session_register("cart");

          $items = 0;

          session_register("items");

          $total_price = "0.00";     

          session_register("total_price");

        }

        if($cart[$new])

          $cart[$new]++;

        else

          $cart[$new] = 1;

        $total_price = calculate_price($cart);

        $items = calculate_items($cart);

    My problem is whenever I run the code below I get the following error

     

    Warning: Invalid argument supplied for foreach() in /home/seachange/domains/sea-change.ie/public_html/cart1/show_cart.php on line 122

     

    However when I just run the php part of this code on its own it runs perfectly and executes everything.

     

    As you prob can see Im a beginner but if their is a fix to this please let me know
