[SOLVED] arrays for cart

[M.O.S. Studios]

hey guys im attempting my own cart. here is my prob, i have a script that reads $_GET dadt and places it into a array variable, how ever it only seem to work once, im havingtrouble getting the two to combine, here is my script

 

 

here is the url it see has blahblah/cart.php?action=add&cat=hotrods&item_number=B001

<?php

session_start();

$cart = $_SESSION['cart'];

 

if($_GET['action']==add)

{

if($cart)

{

$cart .=",". array(cat=> $_GET['cat'], item_number=> $_GET['item_number'], qty=>1);

}

else

{

  $cart=array(cat=> $_GET['cat'], item_number=> $_GET['item_number'], qty=>1);

}

$_SESSION['cart'] = $cart;

}

 

$cart=array($_SESSION['cart']);

echo "catagory item qty <br/>";

echo $cart['cat']." ".$cart['item_number']." ".$cart['qty'];

//echo "<br/>"." ".$cart['1']['cat']." ".$cart['1']['item_number']." ".$cart['1']['qty'];

print_r ($cart);

 

this first time i add that prod it give me this

 

 

Array ( [0] => Array ( [cat] => hotrods [item_number] => B001 [qty] => 1 ) )

 

what i want, is if i click the prod again it will give me this

 

Array ( [0] => Array ( [cat] => hotrods [item_number] => B001 [qty] => 1,

          [1] => Array ( [cat] => hotrods [item_number] => B001 [qty] => 1)

 

instead it gives me this:

 

Array ( [0] => Array,Array )

 

can any one see my mistake?

Try:

<?php

session_start();

$cart = $_SESSION['cart'];

 

if($_GET['action']==add)

{

  $cart[]=array(cat=> $_GET['cat'], item_number=> $_GET['item_number'], qty=>1);

$_SESSION['cart'] = $cart;

}

 

It'll be a multi-dimensional array of products.

WOW! thanks for that amazingly fast reply!!!

 

i tried your code and it gave me this error:

 

Fatal error: [] operator not supported for strings in /home/montrea1/public_html/lm/cart/cart.php on line 7

 

 

here is the new code

 

<?php

session_start();

$cart = $_SESSION['cart'];

 

if($_GET['action']==add)

{

$cart[]=array(cat=> $_GET['cat'], item_number=> $_GET['item_number'], qty=>1);

$_SESSION['cart'] = $cart;

}

 

print_r ($cart);

?>

 

any ideas?

Clear your session first.  It's because of the old session code.  Just clear it and start a new one. =P

[DarkWater]

Also, change it to this:

 

<?php

session_start();

$cart = $_SESSION['cart'];

 

if($_GET['action']==add)

{

$cart[]=array('cat'=> $_GET['cat'], 'item_number' => $_GET['item_number'], 'qty' =>1);

$_SESSION['cart'] = $cart;

}

 

print_r ($cart);

?>

 

There was just some less-than-optimal code because you forgot the ' ' around the array keys.  I added them.  Won't affect the error though, so you'll still need a new session.

THANKS SO MUCH, it took me all day to get it, and you not even 5 mins (thank includes that time it took you to write the post)

No problem, glad to help.  Please mark this topic as solved.  Also, just for reference (and to maybe reduce the need for another post), when you want to iterate over the cart, here's how you can do it:

 

foreach ($_SESSION['cart'] as $row) {

  echo $row['item_number']; //etc, etc

}

 

That's how the array's formatted.
