[RESOLVED] incrementing array

[AndreF]

I want to create a shopping cart for myself. It should allows "Continue to Buy" with multiple products before checkout.
What is selected in cart, will be in an array-formated session like this:
$_SESSION[$i]['cart_info'] = array();

I think when I want to allow multiple orders in one cart, $i should incremented that the second and thirs order won't be overriden the first order info?

So for first run $i should be incremented and each time "continue to buy" button is pressed, $i should be incremented to create a new session?

Isn't there any better way to handle a multiple order in one cart? If there is not, then how to increment $i with each button press and first time it should be 0?

Hi,

You can just create the cart, and add items:

$_SESSION['cart']=array();
$_SESSION['cart'][] = 'Item 1';
$_SESSION['cart'][] = 'Item 2';

php will automatically increment the counter for the index for you this way. You can access them through:

foreach($_SESSION['cart'] as $arraykey => $item)
  {
  echo "key ".$arraykey." has value: ".$item."<br />";
  }

actually the array has some things as second dimension like:
$SESSION['cart_info']['price']
$SESSION['cart_info']['discount']
$_SESSION['cart_info']['setup_fee']

so they should look like this?
$SESSION['cart_info'][]['price']
$SESSION['cart_info'][]['discount']
$_SESSION['cart_info'][]['setup_fee']

or is there a better way to do this?

If someone can just tell me how can I make an aray like this format, then you will know what actually I am trying to ask.

EDITED!

How can I make an array like above?

[leatherback]

like this?

$_SESSION['cart'][] = array(
'name'=>'Item 1',
'price'=>'99',
'discount'=>25);

[AndreF]

Like this:

Array (
       Array (
            [name]=>Item 1
            [price]=>99
            [discount'=> 25
      )
      Array (
             Second order details will be here. IF ANY
      )
      Array (
             Third order details will be here. IF ANY
      )
)

In order to add that second, thirs, 4th..... order details if they is any then how should the followings look like?

$_SESSION['cart_info'] = array()
$_SESSION['cart_info']['name'] = value
$_SESSION['cart_info']['price'] = value
$_SESSION['cart_info']['discount'] = value

pklease advice.

Matt,

the code in post ~5 does just that. Just give it a try in an empty page e.g.,

session_start();
// item 1:
$_SESSION['cart'][] = array(
'name'=>'Item 1',
'price'=>'99',
'discount'=>25); 

// item 2
$_SESSION['cart'][] = array(
'name'=>'Item 2',
'price'=>'78',
'discount'=>15); 

echo '<pre>';
print_r($_SESSION);
echo '</pre>';

[AndreF]

We don't know the product name is item 1 and its price is 99. these are selected by user in cart, so they should not be hardcoded in session like you gave.
it should use something like:
$SESSION['cart_info']['name'] = value
$SESSION['cart_info']['price'] = value

how things above should look like?

[leatherback]

Hehe.. you didn't understand what I am talking about, and/or didn't tell me that you don't know how to get your values from the form/link into your session... You -obviously- can replace anything that is hardcoded by variables

session_start();

$item_name= $_POST['name'];

// get your item deatils from e.g. database, or similarly from the posted data
// Getting it from posted data will be insecure, as users can spoof your form

$_SESSION['cart'][] = array(
'name'=>$item_name,
'price'=>$item_price,
'discount'=>$discount);

[AndreF]

so adding a dimension to the followings won't work?

$SESSION['cart_info'][]['name'] = value
$SESSION['cart_info'][]['price'] = value

[leatherback]

I am not sure; I never do it that way.

However, if you are generating load of values through your code (Which I presume is why you would like to do it that way) you could just at the start create a product array, fill that and at the end of the page update the cart?

$product = array();
$sproduct['id']=$_POST['pid'];
// blablabla...

$product['name'] = row['name'];

// blablabla

$_SESSION['cart'][] = $product;

Yes, it worked thank you I would mark this thread as resolved.

[AndreF]

we have an array lik ethis:

Array
(
    [2] => Array
        (
            [blah] => foo
        )

)

Then how can we know what the element number is? (e.g. in this example 2)

[leatherback]

see before

Foreach($array as $key=>$value)
  {
  echo 'key: '.$key;
  }

Just a short note to thanks a lot for all kind helps. This issue is closed! 🙂
