What you're trying to do?  You can use the uniqid function.

Thanks for quick reply ok then how do i say get id=1 from uniqid 

 

thanks

Explain what you're trying to do.  Do you want a unique ID, or do you want the number 1?

 

What will this be used for and why do you want it?

[raptor30506090]

ok what im trying to do is get the session to add new product in with same id so product_1 id_1    and product_2 id_1

the reason for this is so i can add options to the cart only way at mo i can think of doing it

 

cheers

You don't have a database with product IDs?

 

The session is unique for every user, they don't SHARE the session like they do a database.

No what im trying to do is my products will have options like size 8 ?4.99 size 9 ?5.99 so when at the mo they select an option it replaces the last price so im trying to make it add a new session name hope that helps or im going mad

ok im not getting any were with this can some one give me an idea how to go about putting options in a form to make choice payment in my cart and if they add more than 1 of the same

 

Thanks sorry to be a pain

If English is not your first language, just try to say MORE on the subject so we can get an idea of what you mean.

 

What you need to be doing is storing the cart in the session using the product ID as the key:

 

$_SESSION['cart'][$productId] = array('quantity' => 5, 'price' => 9.99, 'options' => array( 'color' => 'green', 'size' => 'medium' ) );

[raptor30506090]

this is were im a bit stuck if they orderd

 

$_SESSION['cart'][$productId] = array('quantity' => 5, 'price' => 9.99, 'options' => array( 'color' => 'green', 'size' => 'medium' ) );

 

and then same person orderd

 

$_SESSION['cart'][$productId] = array('quantity' => 5, 'price' => 19.99, 'options' => array( 'color' => 'blue', 'size' => 'large' ) );

 

would that over right the first order?

 

thanks

When you go to add a product to the cart, check to see if it's already in the cart.  if it is, only update the quantity.

[raptor30506090]

Sorry ManiacDan

 

if you looked at what i put iv changed the last 3 colour , price and size would this create a new product listing so we would have two products in the cart?

 

 

[ManiacDan]

I don't know, that's a business rule.  What do you want to happen when they do that? 

 

If I bought 3 green shirts at $9.99, then 15 red shirts at $8.00, would you really make an entry for 18 shirts?  How would you ever figure out the original order?

 

If it were me, I'd probably use the same idea I gave you earlier, except $_SESSION['cart'][$productId] would be an array of products, each with their own quantities and specifications.  if all specifications matched, I'd update the quantity.  If any one of them did not match, I'd add a new row. 

 

Obviously, if $_SESSION['cart'][$productId] didn't already exist I'd add a new array of products, like this:

 

 

$_SESSION['cart'][$productId] = array( array( 'quantity' => 5, 'price' => 9.99, 'options' => array( 'color' => 'green', 'size' => 'medium' ) ) );
