hey all,
For some reason while trying to use a shopping cart script in IE6 and Opera that works fine in other browsers, it doesn't seem to be accepting the $POST variables to pass on to $SESSION. I think the problem lies in my form_check() function but I'm not sure why. Here's the PHP for that section, and the section that displays the basket (my full code is too long for the forum)
PHP:
<?php
function form_check()
{
// check to see if the form has been submitted
// and which submit button was clicked
// if this is an add operation
// add to already existing quantities in shopping cart
if ($_POST['add'])
{
foreach ($_POST['a_qty'] as $k => $v)
{
// if the value is 0 or negative
// don't bother changing the cart
$kid = explode(':', $k);
// key
$product = $kid[0];
// size
$colour = $kid[1];
// colour
$size = $_POST['a_size'][$k];
// quantity
$quant = $v;
if ($v > 0)
{
$added = 'no';
foreach ($_SESSION['cart'] as $key => $value)
{
$sesh = explode(':', $value);
if ($sesh[0] == $product && $sesh[1] == $colour && $sesh[2] == $size)
{
$_SESSION['cart'][$key] = $product . ':' . $colour . ':' . $size . ':' . $quant;
$added = 'yes';
}
else if ($sesh[0] == $product && $sesh[1] == $colour && $sesh[3] == $quant)
{
$_SESSION['cart'][$key] = $product . ':' . $colour . ':' . $size . ':' . $quant;
$added = 'yes';
}
}
if ($added == 'no')
{
$_SESSION['x']++;
$key = $_SESSION['x'];
$_SESSION['cart'][$key] = $product . ':' . $colour . ':' . $size . ':' . $quant;
}
}
}
}
else if ($_POST['addremote'])
{
foreach ($_POST['ar_qty'] as $k => $v)
{
$quant = $v;
}
foreach ($_POST['ar_size'] as $k => $v)
{
$size = $v;
}
foreach ($_POST['ar_colour'] as $k => $v)
{
$colour = $v;
$product = $k;
}
if ($v > 0)
{
$added = 'no';
foreach ($_SESSION['cart'] as $key => $value)
{
$sesh = explode(':', $value);
if ($sesh[0] == $product && $sesh[1] == $colour && $sesh[2] == $size)
{
$_SESSION['cart'][$key] = $product . ':' . $colour . ':' . $size . ':' . $quant;
$added = 'yes';
}

$added = 'yes';
}
}
if ($added == 'no')
{
$_SESSION['x']++;
$key = $_SESSION['x'];
$_SESSION['cart'][$key] = $product . ':' . $colour . ':' . $size . ':' . $quant;
}
}
}
// if this is an update operation
// replace quantities in shopping cart with values entered
else if ($_POST['update'])
{
foreach ($_POST['u_qty'] as $k => $v)
{
$kid = explode(':', $k);
$key = $kid[0];
// key
$product = $kid[1];
// size
$colour = $kid[2];
// colour
$size = $_POST['u_size'][$k];
// quantity
$quant = $v;
// if the value is empty, 0 or negative
// don't bother changing the cart
$value = $product . ':' . $colour . ':' . $size . ':' . $quant;
if ($v != "" && $v >= 0)

$_SESSION['cart'][$key] = $value;

}
header( 'Location: checkout.php' ) ;
}
// if this is a clear operation

$_SESSION = array();
session_destroy();

function display_basket()

$subtotal = $row['price'] * $id[3];

Any ideas?
