Im writing sales software that will be walking through a set of pages and on certain pages there are items listed to sell and when you click buy it basically just passes a hidden variable to the next page to be set as a session variable, and then when you get to the end it call gets reported to a database. However my employer wanted me to include a shopping cart, and this shopping cart should display the item name, sku, and price of whatever you're buying, as well as a remove button so the person doing the script doesnt need to go back through the entire thing to remove one item. At the moment I have the cart set to display everything, which was fairly simple. but I cant figure out how to get the remove button to work. Here is the code for the shopping cart:
$total = 0;
//TEST CODE:
$_SESSION['itemname-addon'] = "Test addon";
$_SESSION ['price-addon'] = 10.00;
$_SESSION ['sku-addon'] = "1234h";
$_SESSION['itemname-addon1'] = "Test addon1";
$_SESSION ['price-addon1'] = 99.90;
$_SESSION ['sku-addon1'] = "1111";
$_SESSION['itemname-addon2'] = "Test addon2";
$_SESSION ['price-addon2'] = 19.10;
$_SESSION ['sku-addon2'] = "123";
//end test code
$items = Array
(
"0"=> Array
(
"name" => $_SESSION['itemname-mo'],
"price" => $_SESSION ['price-mo'],
"sku" => $_SESSION ['sku-mo']
),
"1" => Array
(
"name" => $_SESSION['itemname-addon'],
"price" => $_SESSION ['price-addon'],
"sku" => $_SESSION ['sku-addon']
),
"2" => Array
(
"name" => $_SESSION['itemname-addon1'],
"price" => $_SESSION ['price-addon1'],
"sku" => $_SESSION ['sku-addon1']
),
"3" => Array
(
"name" => $_SESSION['itemname-addon2'],
"price" => $_SESSION ['price-addon2'],
"sku" => $_SESSION ['sku-addon2']
)
);
$a_length = count($items);
for($x = 0; $x<$a_length; $x++){
$total +=$items[$x]['price'];
}
$formattedtotal = number_format($total,2,'.','');
for($i = 0; $i < $a_length; $i++){
$name = $items[$i]['name'];
$price = $items[$i]['price'];
$sku = $items[$i]['sku'];
displaycart($name,$price,$sku);
}
echo "<br />
<b>Sub Total:</b>
$$formattedtotal";
function displaycart($name,$price,$sku){
if($name != null || $price != null || $sku != null){
if ($name == "no sale" || $price == "no sale" || $sku == "no sale"){
echo "";
}
else{
$formattedprice = number_format($price,2,'.','');
echo "$name: $$formattedprice ($sku)";
echo "<form action=\"\" method=\"post\">";
echo "<button type=\"submit\" />Remove</button><br />";
echo "</form>";
}
}
}
So at this point Im not sure where to go from here for the remove button. Any suggestions would be appreciated.
