Hi Everyone,

I'm building a custom shopping cart. I'm having trouble getting my code to work on a production server that is running PHP version 5.2.17. My test machine is running version 5.3.0 and the code works just fine. I do not have the ability to upgrade the version of PHP on the production machine. Here is part of my code. If we can fix this, I can fix the other switch cases:



//this code adds the item to the cart and creates an array and session variable for the cart. The array is multidimensional (item id1 => quantity, item id2 => quantity, item id3 => quantity and so on...).

if (isset($_GET["action"]))
{
    $action = $_GET["action"];
    $id = $_GET["id"] ;
    $q = $_GET["quantity"];
    $cart = array();

switch ($action)

{

case "add":

if ($_SESSION["cart"])

{

$cart = $_SESSION["cart"];

if (array_key_exists($id,$cart))

{

$cart[$id] = $cart[$id] + $q;

}

else

{

$cart[$id] = $q;

}

}

else

{

$cart[$id] = $q;

}

$_SESSION["cart"] = $cart;

break;

}
}

//this code displays the cart array 

if ($_SESSION["cart"])
{
    $cart = $_SESSION["cart"];

foreach($cart as $key => $value)

{

$runQ1 = mysql_query("SELECT * FROM products WHERE id='$key'") or die(mysql_error());

$results = mysql_fetch_array($runQ1);

print "<table><tr><td>$results[1]</td><td>$results[2]</td><td>$results[3]</td><td>$results[4]</td></tr></table>";

}
}
else
{

print "<table><tr><td>There are no items in your shopping cart.</td></tr></table>";

}



The cart session variable is being set but it is only holding one item at a time. If I add a second item to the cart, the 1st item disappears and only the second one is present in the session variable and the table. I'm not sure if it is a session problem or an array problem. Please help before I lose all of my hair! I don't understand why this code works on 5.3.0 and not 5.2.17...

Thanks in advance!

Hi all,

But of a PHP newbie so treat me nice but this one is driving me nuts 

I have the exact same login.php file running on two different servers and they have slightly different versions of PHP installed as follows:

1. PHP Version 5.0.4 - version http://www.trafficpaymaster.com/tpm/phpversion.php
2. PHP Version 5.2.15 - version http://www.dentistsinflorida.org/tpm/phpversion.php

The login works fine on the first server from he
http://www.trafficpaymaster.com/tpm/login.php

Email: test@test.com
Pwd: test

But try it on the second server he
http://www.dentistsinflorida.org/tpm/login.php

Using the same email and password (which is correct) it just loops round not letting the user into the main script at index.php

Question:  Why?
What have I got wrong for that later version of PHP?


Many thanks guys.
