in foreach hell

i am making a little shopping cart want to make a "add to cart page" where the details of what was just added to the cart are shown. The user will be able to proceed to checkout or continue shopping.

Item Price Qty Subtotal
Fight 50.00 1 $50.00

i have this code

<?php 
$qty = -1;
foreach($_SESSION['cart'] as $id => $value) ;
    if($id = $_GET['id']) {
        $qty = $value; 
}
if($qty < 0 ) {
    echo "its 0";
} else  
	?>
 

PHP:

and some output

<tr> <?php $product = find_product($id); ?>
<td><?php echo "Id is   -->",($id); ?></td>
 <?php echo "<br>"; ?>
<td><?php echo "Title is   -->", $product['tite']; ?></td>
 <?php echo "<br>"; ?>
<?php echo "Price is   -->"; ?>
<td><?php  echo number_format($product['price'],2); ?></td>
 <?php echo "<br>"; ?>
 <?php echo "Quanity is   -->"; ?>
<td><input type="text" size="2" maxlength="2" name="<?php echo $id ?>" value="<?php echo $qty; ?>" </td>
 <?php echo "<br>"; ?>
  <?php echo "Total price is   -->"; ?>
<td>$<?php echo number_format($product['price']* $qty, 2); ?></td>
</tr>

PHP:

the output displays with 3 times added to the cart of the id of 1

Id is -->1
Title is -->Halo 3
Price is -->55.00
Quanity is -->3
Total price is -->$165.00



the array looks like this and everything is fine with 3 items in the cart with and id of 1.

Array ( [1] => 3 )

i add another item to the cart (id 2) and it still works fine

Id is -->2
Title is -->Fight Night Rd 3
Price is -->50.00
Quanity is -->1
Total price is -->$50.00

the array looks like this

Array ( [1] => 3 [2] => 1 )

now i go back and add another item with an id of 1 to the cart and this is where it goes bad.

Id is -->1
Title is -->Halo 3
Price is -->55.00
Quanity is -->1
Total price is -->$55.00

the id is right
the title is right
the price is right
the quanity is wrong
and the total price is wrong because the the quanity is wrong however the price amount is right.

but my arrray says

Array ( [1] => 4 [2] => 1 )

i can not get it to go back and read the first element in the array again. it is stuck reading the 1 of [2] =>1 and can not fix it without clearing the cookies of the browser. can anyone help?

 

Try

if($id = $_GET['id'])

Code (php):

to replace the

if($id == $_GET['id'])

Code (php):

 

not didnt work
if($id == $_GET['id'])


it turns quantity to a -1 for the first array

the second (last) array works the same

 

Looks like you got a semicolon where you don´t want it to be.

foreach($_SESSION['cart'] as $id => $value) ;

PHP:

The semicolon at the end of this line makes your for loop do nothing. You probably change it to :

foreach($_SESSION['cart'] as $id => $value) {

PHP:

and put the closing } wherever you want your loop to end. I feel like I might be missing something because this error would imply that your cart wouldn´t work at all.
