Session array

[laqutus]

How can I create a session array populate it with only one item (id), and then add other  items without overwiring the original session?

 

foreach ( $_POST as $key) { echo $key; echo "<br>"; $_session['cart'][] = $key; }?>

    <?

// Attempt to add values into session array

echo '<pre>'; print_r($_session); echo '</pre>';

?>

 

This will take in the one bit of date but is overwritten if I add anything new to it, how can I increment the session array to hold more data (like new row in mysql).

 

The problem is because I could create a new mysql table and have a temporary cart, but flushing the temporary orders (not completed) order would be a pain so I thought it better to create a session array, is this good practice?

 

Cheers

you just assign whatever value you want to a new index

 

$_SESSION['ID'] = "foo";

$_SESSION['stuff'] = "bar";

$_SESSION['hi'] = "!!!";

Ok cool, I understand that, thanks loanwolf, but how do I increment the new index?

 

This is the bit im having trouble with, as If i make the index a variable then it does not seem to work as IO dont know how to check if the index already exists. I want the index to be numerical eg:

 

$_SESSION['1'] = "foo";

$_SESSION['2'] = "bar";

$_SESSION['3'] = "!!!";

I honestly dont know if $_SESSION can be a multidimensional array, since what you are trying to do is something like this i think

 

$_SESSION[iD][value]

 

to check if a session is set though, all you have to do is

 

if (isset($_SESSION['1'])) {

  //do something

}

I dont think $_SESSION can be a multi-dimensional array ?

Yes $_SESSION can be multi-dimensional. It is the same as any other array
