Hey there.
Here's a code to my shopping cart
<?php require_once('../Connections/myDatabase.php'); ?>
<?php session_start(); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}
if ((isset($_POST['cartid'])) && ($_POST['cartid'] != "")) {
$deleteSQL = sprintf("DELETE FROM cart WHERE cartid=%s",
GetSQLValueString($_POST['cartid'], "int"));
mysql_select_db($database_myDatabase, $myDatabase);
$Result1 = mysql_query($deleteSQL, $myDatabase) or die(mysql_error());
$deleteGoTo = "DeleteSuccessfully.php";
if (isset($_SERVER['QUERY_STRING'])) {
$deleteGoTo .= (strpos($deleteGoTo, '?')) ? "&" : "?";
$deleteGoTo .= $_SERVER['QUERY_STRING'];
}
header(sprintf("Location: %s", $deleteGoTo));
}
mysql_select_db($database_myDatabase, $myDatabase);
$query_Cart = "SELECT * FROM cart";
$Cart = mysql_query($query_Cart, $myDatabase) or die(mysql_error());
$row_Cart = mysql_fetch_assoc($Cart);
$totalRows_Cart = mysql_num_rows($Cart);
?>
