index array how?

[gokeeffe]

Hi

Here is my array which works find

$_SESSION['grind_array'][] = array ( 'interest' => $_SESSION['interest'],
'subject' => $_SESSION['subject']
'level' => $_SESSION['level']);


My problem is this how do I get the array index number, as I will need this number in another page to allow the users to delete a certain array item.

For example id someone submits 5 grind_arrays and then they want to remove the second one which is array [1] how can I get this value. Is it something like this.


$_SESSION['grind_array'][] = array ( 'index' => $_SESSION['index'],
'interest' => $_SESSION['interest'],
'subject' => $_SESSION['subject']
'level' => $_SESSION['level']);

How is it possible to delete from an array I was going to use the unset SESSION command to remove the specified array element, is this correct ?

Regards
Graham

When you display the array on the other page you must somehow iterate the array. In that process you will get the key.

foreach ($_SESSION['grind_array'] as $key => $record){
   # $key will be the offset and #record the array of interest, subject etc.
   ... your code here ...
}

In the output create a HTML form element that holds $key so you can use it in the next script that removes elements.
