I created this array


$products = array(
"ibm" => array (
"id" => "ibm",
"qty" => 0,
"name" => "IBM Laptop",
"price" => "200.00"
),
"dell" => array (
"id" => "dell",
"qty" => 0,
"name" => "Dell Laptop",
"price" => "300.00"
),
"gateway" => array (
"id" => "gateway",
"qty" => 0,
"name" => "Gateway Laptop",
"price" => "400.00"




I want to use the foreach funtion to display name price and qty

How can I do this??

PHP Code:

foreach($products AS $name => $info)
{
    echo "<strong>$name</strong>: \${$info['price']} (Qty: {$info['qty']}<br />";
} 


Should do the trick.

Thanks for the input the relsults only show the first part of the name:


ibm: $200.00 Qty: 0
dell: $300.00 Qty: 0
gateway: $400.00 Qty: 0

it shoul say ibm laptop, dell laptop, why is it not showing the second part does it have to do with the white spaces??

Thanks Chroder,

I was able to look as the code you gave me any figure out why
but I still have some questions to I can better understand arrays.

$products is the name of the array and with that array their is arrays call ibm, dell, gateway. on the second part of the foreach statement $name =>$info means that $name stands for ibm,gateway, dell.

does $info stand for an array that contains id,qty,name,price??

why did I have to enclosed some items in {} ??

trying to fully understand array and output



foreach($products AS $name => $info)
{
echo "<strong>{$info['name']}</strong>: \${$info['price']} Qty: {$info['qty']}<br />";
}

A foreach array has two different syntax's:

foreach($array AS $value)

foreach($array AS $key => $value

(You name the variables whatever you want) In our case, we used the second one. Since you have a multidimensional array (meaning an array of an array) then the $value itself is an array, and that explains why $info was holding id,qty,name,price -- because that is the array that $products[anykey] is holding.

As to the {}'s, that's a simpler explanation Curly brackets help PHP distinguish between a variable in double quotes, and normal text in double qoutes. For example, if you wanted to say:

<animal>s are great

With 'animal' as a variable, you would need curly brackets to tell PHP that the 's' is not part of the variable name:

{$animal}s are great

If you try to put quotes around the keyname like $info['price'] then PHP get's confused. You can solve this by using simply $info[price] (no quotes) or by using the curly brackets. Habit just makes me choose the latter. You can read more in the manual, the part's on 'Simple' and 'Complex' syntax.

thanks for the explanation

Okay, I created the foreach listed below

foreach($products AS $name => $info)
{

echo "<tr>";
echo "<td>{$info['name']}</td>";
echo "<td>\${$info['price']}</td>";


Then I added this line to pass the about of items that have been added to $_SESSION['cart']

echo "<td><a
href=$_SERVER[PHP_SELF]?buy=$products>BUY</a></td>";

am I passing the right array to the $_SESSSION['cart']

I need the display the items(dell laptop, etc) and the quantity (1,2, etc)of them in the cart

$products is the array itself, you cannot pass an entire array as a query string (other then to serialize it, which is not efficient in this situation).

You'd want to pass the 'id' in the query string

echo "<td><a href=$_SERVER[PHP_SELF]?buy=$info[id]">BUY</a></td>";

how is passing buy=$info['id'] to the $_SESSION array going to help be create

name price qty


and have to qty change with each time I select it example

Dell Laptop $200.00 5

I am confused because I have never worked with session and arrays

There is a cart script that was written by Ying Zhang which I first saw in a tutorial (I think on PHP Builders, not positive) quite some months ago.

It just recently resurfaced on OpenSourceCMS as a demo and is more polished. It was written for educational and demonstration purposes only, but has a very good foundation laid into it for session tracking and the cart.

You might be interested in this and you can demo it at OpenSource, it is called MyMarket. The script is very small, well as scripts of this type are considered.

I am actually using this script to build a cart for an existing site that I am working with. The site currently is passing the purchasing off to a Yahoo Store, but we are losing sales with this method. I have adapted it to feed off of the inventory at the Ystore, now all I need to do is the complicated part -- the Payment Gateway with Authorize.NET.

The tutorial was at DevShed (not PHP Builders). I did a lot of searching for cart tutorials, and this one was about the best I found out there. There is another good one at Zend also which was written some time ago, but the principals still apply. That is in a series entitled A PHP Based Shopping Cart

E-Commerce Tutorial [ Part 1 | Part 2 | Part 3 ]
A comprehensive three part tutorial covering each step of how MyMarket was built. It provides background information about user security, shopping carts, and more. These documents reside at DevShed.
