Multidimensional Array Help

[thomashw]

I have a multidimensional array using sessions.

 

The array consists last array in the multidimensional array has a 0 and 1 "key" but it's only displaying the value for the 0 key, and doesn't display the value corresponding to the 1 key.

 

$j = 0;
foreach($_SESSION['cart'][$pid]["$j"] as $key => $value)
{
  echo "$value, ";
  $j++;
}

 

I'm also new to this, so this may be a stupid question.

This is fine for showing what is in the array, but you aren't showing what code made the array. This is where your mistake is. Show the code.

[thomashw]

$i = 0;
while(isset($_POST["option$i"]))
  {
    // Add the options to the array
    $_SESSION['cart'][$pid][] = array("option$i" => $_POST["option$i"]);
    $i++;
  }

 

Thanks.

one the final page with the results, use:

<?php
echo "<pre>";
print_r($_SESSION);
echo "</pre>";
?>

and share that output with me.

Array ( [cart] => Array ( [2] => Array ( [productid] => 2 [quantity] => 1 [price] => 299.99 [0] => Array ( [option0] => Bulb Type: H1 ) [1] => Array ( [option1] => Color Temperature: 4300K ) ) ) )

 

When I use the for loop, it only displays the Bulb Type: H1, and not the Color Temperature: 4300K.

 

Thanks!

If you are getting all this info from a database, wouldn't it be easier to just add a item # and quantity to the cart? When a user views the shopping cart or goes to check out, you could query your database for the details. A properly designed database of items would not have the same part number with options like:

 

part 1, blue

part 1, green

part 1, pink

 

instead you would have:

 

part 1

part 2

part 3

The options are selected by the person on the site, and each part has multiple options to be selected, so I need to "remember" what they selected... there are also multiple categories for options, so if I entered all of the different ways the options could be selected, I'd have thousands for just one part.

can you paste the formatted print_r. Until I fixed it, the output wasn't in pre tags. Take a look up there ^

Wow, that makes it so much more organized!

 

Array
(
    [cart] => Array
        (
            [2] => Array
                (
                    [productid] => 2
                    [quantity] => 1
                    [price] => 299.99
                    [0] => Array
                        (
                            [option0] => Bulb Type: H1
                        )

                    [1] => Array
                        (
                            [option1] => Color Temperature: 4300K
                        )

                )

        )

)

 

Now that I see it like this, the options don't need to be in new arrays. It'd be great to have the options in the $pid array, but the $pid array is created higher in the code. How can I "add" the options to the end of the $pid array instead of creating a new array for the options? I realize I need to remove the "[]" from the end of this code, but how do I just "add" to the $pid array?

 

$i = 0;
while(isset($_POST["option$i"]))
  {
    // Add the options to the array
    $_SESSION['cart'][$pid][] = array("option$i" => $_POST["option$i"]);
    $i++;
  }

[sKunKbad]

$_SESSION['cart'][2][] = 'some option';

 

will add 'some option' to the product in the array shown.

 

I would create an options array inside the product array, that way you can loop through the options when outputting:

 

$pid = 1;
$_SESSION['cart']["$pid"]['options'][] = 'chrome';
$_SESSION['cart']["$pid"]['options'][] = 'gold plated';
$_SESSION['cart']["$pid"]['options'][] = 'diamond encrusted';

 

check the array with print_r(), and you will see that they have been added to the product options array

You rock! Thank you!!
