Hi guys,

I have read a few threads on this but I'm still stuck ! I have an array which is a shopping basket, and it holds details about each item, and a number of items. For example, one users basket may be..

Topside Joint
Cotswold Edge
beef
9
1

Pork
Cotswold Edge
sausages
6.00
1

which is the output as...

$name = $_SESSION['basket'][$key]['name'];
$supplier = $_SESSION['basket'][$key]['supplier'];
$category = $_SESSION['basket'][$key]['category'];
$price = $_SESSION['basket'][$key]['price'];
$qty = $_SESSION['basket'][$key]['qty'];

echo $id . "<br />";
echo $name . "<br />";
echo $supplier . "<br />";
echo $category . "<br />";
echo $price . "<br />";
echo $qty . "<br />";

I KNOW this is a bad method (and it doesn't even work!) but this is how my code currently stands:


foreach($_SESSION['basket'] as $key => $another)
{
$name = $_SESSION['basket'][$key]['name'];
$supplier = $_SESSION['basket'][$key]['supplier'];
$category = $_SESSION['basket'][$key]['category'];
$price = $_SESSION['basket'][$key]['price'];
$qty = $_SESSION['basket'][$key]['qty'];


$sql = "INSERT INTO orders VALUES(0,'".$id."','".$oid."','".$name."','".$pric e."','".$supplier."','".$category."')"
$result = mysql_query($sql, $connection)
or die("MySQL Error: ".mysql_error());
}

How can I do this in a way thats a) better/more efficient and b) just works?

Thanks in advance

Dave

p.s. not sure why, but in the above view $price has a space in it, this does not appear in my code. Cheers

can you print the array or the sql statement here?

print_r($_SESSION);

//or

echo $sql;

Thanks of your reply louie,

this is the print of $_SESSION['basket'] with 2 items in it.

Array ( [0] => Array ( [id] => 1 [name] => Pork [price] => 6.00 [supplier] => Cotswold Edge [category] => sausages [qty] => 1 ) [1] => Array ( [id] => 2 [name] => Pork [price] => 6.00 [supplier] => Cotswold Edge [category] => sausages [qty] => 1 ) )

hopefully you can make sense of it!

Dave

You have a 3D array so you will need another foreach loop inside the "foreach"

when would I run the sql statement?

Could you give me a rough idea of what the code would look like?

Cheers!

what exactly does the $key holds as value?

I'm not sure, sorry a bit new to this. this is my addToBasket.php file which adds items the customer wants, into my array.
<? //removed some irrelevant stuff
$basketArray = array();
$basketArray['id'] = $_GET['id'];
$basketArray['name'] = $_GET['name'];
$basketArray['price'] = $_GET['price'];
$basketArray['supplier'] = $_GET['supplier'];
$basketArray['category'] = $_GET['category'];
$basketArray['qty'] = 1;
$price = $_GET['price'];
$subtotal = $_SESSION['subtotal'];

$found = false;

if(isset($_SESSION['basket']))
{
foreach($_SESSION['basket'] as $key => $another)
{
if($_SESSION['basket'][$key]['id'] == $_GET['id'])
{
$found = true;
break;
}
}
}

if($found == false)
{
$subtotal = ($subtotal + $price);
$_SESSION['subtotal'] = $subtotal;
$_SESSION['basket'] [] = $basketArray;
}
header("Location: foodItems.php?category=".$category."" );
exit();
?>

Something to get you rolling:

$sql = "";
$oid = "someid"; //don't know what that is so I gave it a value
$id = !empty($_GET['id']) ? preg_replace("#[^0-9]#","",$_GET['id']) : "111";
$name = !empty($_GET['name']) ? preg_replace("#[^0-9a-zA-Z\- ]#","",$_GET['name']) : "name";
$price = !empty($_GET['price']) ? preg_replace("#[^0-9]#","",$_GET['price']) : "999";
$supplier = !empty($_GET['supplier']) ? preg_replace("#[^0-9a-zA-Z\- ]#","",$_GET['supplier']) : "SUPPLIER";
$category = !empty($_GET['category']) ? preg_replace("#[^0-9a-zA-Z\- ]#","",$_GET['category']) : "CATEGORY";

$basketArray = array();
$basketArray['id'] = $id;
$basketArray['name'] = $name;
$basketArray['price'] = $price;
$basketArray['supplier'] = $supplier;
$basketArray['category'] = $category;
$basketArray['qty'] = 1;
//$price = $_GET['price'];
$subtotal = !empty($_SESSION['subtotal']) ? $_SESSION['subtotal'] : "0";
$found = false;
//print_r($basketArray);
if(!empty($_SESSION['basket'])) {
foreach($_SESSION['basket'] as $key) {
foreach($key as $x=>$y){
echo $x."-".$y."<br />";
if($y == $id) {
$found = true;
echo "<h1>found</h1>";
break;
}
}
}
}
if(!$found) {
$subtotal = ($subtotal + $price);
$_SESSION['subtotal'] = $subtotal;
$_SESSION['basket'][] = $basketArray;
//insert data to DB
$sql = "INSERT INTO orders VALUES(0,'".$id."','".$oid."','".$name."','".$pric e."','".$supplier."','".$category."')";
}else{
//update quantity
$sql = "UPDATE orders.....";
}
//header("Location: foodItems.php?category=".$category."" );
//exit();
//print_r($_SESSION['basket']);

if($sql != ""){
echo "<h1>".$sql."</h1>";
//$result = mysql_query($sql, $connection)
//or die("MySQL Error: ".mysql_error());
}

so, was the above code any help to you?
