multidimensional array can't comprehend

[Rifts]

Hey guys I am trying to make a simple shopping cart but I can't seem to wrap my head around this.

 

I have $_SESSION['cart'] as an array and I can add an item to it and then echo specific elements of the item like so

 

echo $_SESSION['cart']['0']['Name'];

 

I can not seem to figure out how to add a second item to the array so I can do something like

 

echo $_SESSION['cart']['1']['Name'];

 

and it will echo the second item that I 'added' to my cart?

 

Thanks I hope that makes sense.

Here is part 1 of a series of youtube videos where the guy goes through everything you need to create a shopping cart. He uses multi arrays too.

 

I have learnt all my php from this dude, he's very good. You can watch the whole series and get a firm grasp on everything, or you can just find the video where he talks about the multi arrays .

 

Enjoy

the multidimensional array ah yes

 

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

$_SESSION['cart']['0']['Name'] = 'product 1';

$_SESSION['cart']['1']['Name'] = 'product 2';

$nextnum = count($_SESSION['cart']) + 1;

$_SESSION['cart'][$nextnum]['Name'] = 'product 3';

print_r($_SESSION['cart']);

 

so by using the count function you always know where you are up to in the array, then add 1 for the next 'key' to assign it's 'value'

ahhhhh I see that is really helpful thank you both!

Hey so i'm not sure what I'm doing wrong here.

 

for some reason when I try to add a new product the $nextnum var wont increase so it just keeps overwritting the first product.

 

I have this and then a form to "add to cart" or submit it via post

 

<?php
session_start();

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




$nextnum = count($_SESSION['cart']) + 1;

echo $nextnum;

$_SESSION['cart'][$nextnum]['name'] = $_POST['name'];
$_SESSION['cart'][$nextnum]['id'] = $_POST['id'];
$_SESSION['cart'][$nextnum]['price'] = $_POST['price'];
$_SESSION['cart'][$nextnum]['size'] = $_POST['size'];
$_SESSION['cart'][$nextnum]['color'] = $_POST['color'];

print_r($_SESSION['cart']);		


?>

$_SESSION['cart'][$nextnum]['name'][] = $_POST['name'];

 

or

 

$_SESSION['cart'][$nextnum]['name'][$nextnum] = $_POST['name'];

ok well i figured that out out I have a new question lol

 

I can not seem to get the number of that array for example

 

say there are 3 things in the cart array

 

$count = count($_SESSION['cart']);
for($i=0;$i<$count;$i++){
echo $_SESSION['cart'][$i];
}

 

instead of listing 0,1,2  it just says Array,Array,Array

 

why is that?

[BlueSkyIS]

because each thing inside $_SESSION['cart'] is an array. when you loop over them and echo them, you get array because that's what they are.

ok so what do I need to do to get the spot in the cart array they are?
