Hello I am having some difficulty with my shopping cart script. So far I have it so you can update how many quantities of the item you want and it also updates the price as well. I want it so that once you click a button that says "Add To Cart" it sends you to a page that displays your order and tells you the Quantity, Unit Price and Total Cost of it.
Below is the code I have so far.
Javascript:
<script type="text/javascript">
$(document).ready(function() {
$("#Quantity").keypress(function(event) {
return /\d/.test(String.fromCharCode(event.keyCode));
});
$("#Quantity").change(function(event) {
$(this).val(Math.abs($(this).val()));
UpdatePrice();
});
$("#CartForm").submit(function(event) {
if(!isNormalInteger($("#Quantity").val()))
{
event.preventDefault();
alert("Sorry, you must select at least one of these DVD's!");
return false
}
});
UpdatePrice();
});
function UpdatePrice() {
var AdjustedPrice = parseFloat($("#BaseUnitPrice").val())*parseInt($("#Quantity").val());
$("#AdjustedPrice").html(AdjustedPrice.toFixed(2) + $("#Currency").val());
}
function ChangeQuantity(Value) {
var NewQuantity = parseInt($("#Quantity").val()) + parseInt(Value);
if(NewQuantity < 1) NewQuantity = 1;
$("#Quantity").val(NewQuantity);
UpdatePrice();
}
function isNormalInteger(str) {
return /^\+?(0|[1-9]\d*)$/.test(str);
}
</script>
HTML/PHP:
echo'<div class="right"><img alt="Picture" src="dvdcovers/wolverine.jpg" height="100" width="100" /></div>';
echo'<font color="white">';
echo'<br />';
echo'<b>Title:</b> The Wolverine';
echo'<br />';
echo'<b>Quantity:</b> $Quantity;';
echo'<br />';
echo'<b>Unit Price:</b>';
echo'<br />';
echo'<b>Total Cost:</b>';
echo'</font>';
echo'<br /><br />';
echo'<h3 class="widget-title">Purchasing And Payment</h3>';
echo'<form action="cart.php" method="post" id="CartForm">';
echo'<b>Unit Price: </b><div id="AdjustedPrice"></div>';
echo'<br />';
echo'<input type="hidden" id="Currency" value=" AUD" />';
echo'<input type="hidden" id="BaseUnitPrice" name="UnitPrice" value="29.99" />';
echo'<input type="hidden" name="ProductCode" value="000" />';
echo'<br />';
echo'<input type="text" id="Quantity" name="Quantity" value="1" />';
echo'<input type="button" value="-" onclick="ChangeQuantity(-1);" />';
echo'<input type="button" value="+" onclick="ChangeQuantity(1);" />';
echo'<br />';
echo'<input type="Submit" value="Buy" />';
echo'</form>';
Basically I would like to know how to get the value of quantity, unit price and total cost to a new php page that displays these details. Any help would be great. Thankyou.
Have you tried storing variables in a session after you submit the form?
/*
Cart.php
*/
// start session
session_start();
// store session data
$_SESSION['Quantity'] = $_POST['Quantity'];
$_SESSION['UnitPrice'] = $_POST['UnitPrice'];
$_SESSION['TotalCost'] = $_SESSION['UnitPrice'] * $_SESSION['Quantity'];
echo "<br>Quantity => " .'$'. $_SESSION['Quantity'];
echo "<br>UnitPrice => " .'$'. $_SESSION['UnitPrice'];
echo "<br>TotalCost => " .'$'. $_SESSION['TotalCost'];
