if ( ! isset ( $_SESSION['items'] ) )
{

   $_SESSION['items'] = array ( $_GET['item'], 1);
   
} else {

if ( ! in_array ( $_GET['item'], $_SESSION['items'] ) )
     {
     $_SESSION['items'][] = $_GET['item'];
     $_SESSION['items'][$_GET['item']][] = 1;

     } else {
     $_SESSION['items']['$item_to_add'][] = $_SESSION['items']['$item_to_add'][] + 1;
     }
     
     
}

if ( isset ( $_SESSION['items'] ) )

{

foreach ( $_SESSION['items'] AS $item){

      foreach( $_SESSION['items'][$item][] AS $qty){
      
        echo $item . "x". $qty;
         }
         
         }
         

} else {


echo "No Items exist!";

     
}

?>

 

 

Could someone please help, I keep getting an error of:

Fatal error: Cannot use [] for reading in C:\xampp\htdocs\hrfinal\inc.additem.php on line 20

[gevans]

$_SESSION['items']['$item_to_add'][] = $_SESSION['items']['$item_to_add'][] + 1;

 

You cannot assign a variable with no reference;

 

$_SESSION['items']['$item_to_add'][] + 1;

 

this needs to be something along the lines of;

 

$_SESSION['items']['$item_to_add'][0] + 1;

Okay sweet, that error is fixed, now I'm getting

 

 Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\hrfinal\inc.additem.php on line 32

Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\hrfinal\inc.additem.php on line 32

 

Really don't understand how I would go about displaying each item and its qty.

 

heres the updated code

 

<?php
session_start();

$item_to_add = $_GET['item'];


if ( ! isset ( $_SESSION['items'] ) )
{

   $_SESSION['items'] = array ( $_GET['item'], 1);
   
} else {

if ( ! in_array ( $_GET['item'], $_SESSION['items'] ) )
     {
     $_SESSION['items'][] = $_GET['item'];
     $_SESSION['items'][$_GET['item']][] = 1;

     } else {
     $_SESSION['items']['$item_to_add'][1] = $_SESSION['items']['$item_to_add'][1] + 1;
     }
     
     
}

if ( isset ( $_SESSION['items'] ) )

{

foreach ( $_SESSION['items'] AS $item){

      foreach( $_SESSION['items'][$item][1] AS $qty){
      
        echo $item . "x". $qty;
         }
         
         }
         

} else {


echo "No Items exist!";

     
}

?>

if ( isset ( $_SESSION['items'] ) && is_array($_SESSION['items']))

 

Obviously the $_SESSION['items'] is not an array. So something is messing up somewhere when you are trying to define it as an array. Maybe you are using the old session. close your browser and open a new one and try again.
