Hi,

   I am trying to add cart items using session.

Code: Select all

if (!isset($_SESSION['cartId'])) $_SESSION['carId'][] = $_POST['cartId']; 
    else array_push($_SESSION['cartId'],$_POST['cartId']);

I am getting error, first arg must be array.


Thanx

So I think you should "return " http://cz.php.net/manual/cs/function.is ... .isset.php

If _SESSION[cartid] does not exists it's not an array. And you can only use [] on an existing array.
try

Code: Select all

if (!isset($_SESSION['cartId']) || !is_array($_SESSION['cartId'])) {
	$_SESSION['carId'] = array();
}
$_SESSION['cartId'][] = $_POST['cartId'];

Try...

Code: Select all

if (// check if $_POST['cartid'] is valid) {
  if (!isset($_SESSION['cartId'])) {
    $_SESSION['carId'] = array($_POST['cartId']);
  } else {
    $_SESSION['carId'][]=$_POST['cartId']); 
  }
}
Note: Check the user input for cartid. Never trust user input...

Edit: Beat me to it Volka...

if (!isset($_SESSION['cartId']) || !is_array($_SESSION['cartId'])) { 
        $_SESSION['carId'] = array($_POST['cartId']); 
} 
else { 
        $_SESSION['cartId'][] = $_POST['cartId']; 
     }
	 
print_r($_SESSION['carId']);
array_push()?

I am not getting the error. But, i am not able to add new values. The values are over written in [0].

You are missing a 't' in 'cartID' on line 2. Here's volka's code with the typo fixed -- it should work fine:

Code: Select all

if (!isset($_SESSION['cartId']) || !is_array($_SESSION['cartId'])) {
        $_SESSION['cartId'] = array();
}
$_SESSION['cartId'][] = $_POST['cartId'];

I want to display in cart page. If the values are repeated in the array, i should display the number of times the product is selected. How do i do it?

Code: Select all

$cardId=$_SESSION['cartId'];


//  Not working- start //
if($Submit=="Del")
  {
       $hiddel=$_POST['hiddel'];
       unset($cardId[$hiddel]);
  }

// Not working - end//


$uniqueCart=array_unique($cardId);
$arrayCount=array_count_values($cardId);

foreach($uniqueCart as $cardIds)
  {
      //code for fetch data from database using $cardIds.
      //displaying the values.
     <input type='hidden' name='hiddel' value='$cardIds'><input type='Submit' name='Submit' value='Del'> //for sending value to delete.

   }
