Understanding sessions

mindapolis · November 8, 2011

I have a question about this code. In the section where it 's finding out if the user has added an item it says

if(isset($_POST['quantity'] && isset($_POST['id']

in my code id is really product_title and is coming from and is coming from a database. Is it okay to substitute product_title for id?

xyph · November 8, 2011

Of course! But be consistent. Change the name of the hidden field to product_title as well.

mindapolis · November 8, 2011

okay, I thought that would be right but just wanted to make sure. Thanks!

mindapolis · November 8, 2011

Now it 's saying Warning: Invalid argument supplied for foreach() in /home/content/a/u/n/auntievics/html/test/checkOut.php on line 357

concerning this Code


foreach($_SESSION['cart'] as $product_title =>  $quantity)
{
	echo "<li>$product_title $quantity</li>"; 
}

I may me incorrect, but if you are now going with xyph's example, using multiple forms for products, also understand that this script is using ONE page. You are creating the variable $cart from $_SESSION['cart'] and adding items and quantity for each product... HOWEVER you are not updating your session after adding these items so when you get the session on a different page, the session items are not showing. In my humble opinion I would say to update the session by adding these lines.

if( isset($cart[$id]) )
	// If so, add quantity to it. (int) forces $id to be returned as an integer.
	$cart[$id] += (int) $quantity;
$_SESSION['cart']=$cart;// ADDED LINE
else
	// Otherwise, set it to the quantity
	$cart[$id] = (int) $quantity;
$_SESSION['cart']=$cart;// ADDED LINE
// Destroy the reference to $cart to avoid acidentally screwing with it elsewhere in the script

I am also unsure about the use of the ampersand on this line. What does it do?

$cart = &$_SESSION['cart'];

trq · November 8, 2011

See http://php.net/references

Drummin · November 8, 2011

So by reference in the case of the code we're looking at, does the session get updated by updating the variable $cart? Or do we need to use $_SESSION['cart']=$cart; after making any changes to $cart.

mindapolis · November 8, 2011

I am really sorry. I'm really confused now. What do I put where?

Drummin · November 8, 2011

See my earlier post that has the lines $_SESSION['cart']=$cart; added to what you're working with. Maybe re-posting the code you are currently testing would be good as well, so we're talking about the same thing.

mindapolis · November 8, 2011

thanks so much for the help! I greatly appreciate it!

<?php
session_start();
if(isset($_POST['empty']) || isset($_SESSION['cart']))
$_SESSION['cart'] = array();  //if a cart is clear or doesn'does not exist yet 
if(isset($_POST['quantity'])  && isset($_POST['product_title']))
{ 
	$product_title = $_POST['product_title']; 
$quantity = $_POST['quantity']; 
$_SESSION['carr']; 
$cart = $S_SESSION['cart'];
// We will store the item and quantity in the array. $array[item] = quantity
// Check if the item is already in the cart
if( isset($cart[$id]) )
	// If so, add quantity to it. (int) forces $id to be returned as an integer.
	$cart[$product_title] += (int) $quantity;
else
	// Otherwise, set it to the quantity
	$cart[$product_title] = (int) $quantity;
// Destroy the reference to $cart to avoid acidentally screwing with it elsewhere in the script
unset( $cart );

Is $_SESSION['carr']; a mis-type? And the extra S?

$_SESSION['carr']; 
$cart = $S_SESSION['cart'];

Should be

$_SESSION['cart']; 
$cart = $_SESSION['cart'];

And so what I was suggesting was changing this section and adding $_SESSION['cart']=$cart; after making any changes to $cart.

if( isset($cart[$id]) )
	// If so, add quantity to it. (int) forces $id to be returned as an integer.
	$cart[$id] += (int) $quantity;
$_SESSION['cart']=$cart;// ADDED LINE
else
	// Otherwise, set it to the quantity
	$cart[$id] = (int) $quantity;
$_SESSION['cart']=$cart;// ADDED LINE
// Destroy the reference to $cart to avoid acidentally screwing with it elsewhere in the script

mindapolis · November 8, 2011

My only concern is I don't have a variable named id. In my database I have product_title

Drummin · November 8, 2011

The top section is not right. Should be

session_start();
if(isset($_POST['empty']) || !isset($_SESSION['cart']))
$_SESSION['cart'] = array();  //if a cart is clear or doesn't exist yet 
if(isset($_POST['quantity'])  && isset($_POST['product_title']))
{ 
	$product_title = $_POST['product_title']; 
$quantity = $_POST['quantity']; 

$cart = $_SESSION['cart'];

My only concern is I don't have a variable named id. In my database I have product_title

Okay, I was going off an earlier post. Not sure if (int) needs to be removed as you're not dealing with an id now. I would take them out and add a check on $_POST['quantity'] if you're concerned about an integer being passed.

if( isset($cart[$product_title]) )
	// If so, add quantity to it. (int) forces $id to be returned as an integer.
	$cart[$product_title] += (int) $quantity;
$_SESSION['cart']=$cart;// ADDED LINE
else
	// Otherwise, set it to the quantity
	$cart[$product_title] = (int) $quantity;
$_SESSION['cart']=$cart;// ADDED LINE
// Destroy the reference to $cart to avoid acidentally screwing with it elsewhere in the script

mindapolis · November 8, 2011

With that code I get this error message.

Parse error: syntax error, unexpected T_ELSE

Drummin · November 8, 2011

OK, with the added lines we need to use brackets. Code not tested.

<?php
session_start();
if(isset($_POST['empty']) || !isset($_SESSION['cart']))
$_SESSION['cart'] = array();  //if a cart is clear or doesn't exist yet 
if(isset($_POST['quantity'])  && isset($_POST['product_title']))
{ 
	$product_title = $_POST['product_title']; 
$quantity = $_POST['quantity']; 

$cart = $_SESSION['cart'];
if( isset($cart[$product_title]) ){
	// If so, add quantity to it.
	$cart[$product_title] += $quantity;
$_SESSION['cart']=$cart;// ADDED LINE
}
else{
	// Otherwise, set it to the quantity
	$cart[$product_title] = $quantity;
$_SESSION['cart']=$cart;// ADDED LINE

// Destroy the reference to $cart to avoid acidentally screwing with it elsewhere in the script
unset( $cart );

okay, I dont have any errors, but The quantity still is not transferring to the check out page. Yes, both pages have the same code.

Drummin · November 8, 2011

IF you add print_r($_SESSION['cart']); to the checkout page, what does it show?

mindapolis · November 8, 2011

This might be hard to explain, but now it 's putting array() under the navbar. I will put the code as well as the links to the pages.

You've got a lot of html issues to address but to start, move this php code out of your table <tr> elements and put the list (<ul> etc) after your table. The array() is shown there because print_r() is between <tr></tr> tags along with your list. Let me know what print_r shows after adding an item to the cart.

<tr>   
<ul>   
<?php
foreach($_SESSION['cart'] as $product_title =>  $quantity)
{
	echo "<li>$product_title $quantity</li>"; 
}
print_r($_SESSION['cart']);
?>
</ul>
</tr>

I'm not sure I'm following you but I put that php code below the table tag and it put array() under the navbar.

<tr>
<td colspan = "6"><h2>Order Information</h2></td>
</tr>
<tr>   

</tr>
<tr>
<td> <input name="Submit" type="submit" value="Order Treats!" /></td><td><input name="reset" type="submit" value="Cancel Order" /> </td>
</tr>
</table>
<ul>   
<?php
foreach($_SESSION['cart'] as $product_title =>  $quantity)
{
	echo "<li>$product_title $quantity</li>"; 
} 
print_r($_SESSION['cart']);
?>
</ul>
</form>

The point is after submitting your form does array() then hold the values you expect. This is why I've asked what does print_r show after submitting the form. Is it still array() or is it something like array(product_name => 2).

print_r is a debugging feature. It outputs the structure of an array to verify it contains what you want it to. Generally, it's hard to read when displayed in a browser. You need to either view-source or surround it in <pre> tags to see the formatting.

When you print_r() an empty array, it will simply output

Array
(
)

This will appear as

Array ( )

if you don't surround it in pre tags, or aren't viewing the source of the page.

It 's just putting array().
