Re: [PHP] arrays and sessions

[Justin Patrin]

First of all, make sure you're doing session_start() before 
reading/writing any session data and before you do any output.

Second, You likely need to just do something like this:

session_start();
if(post data) {
  $_SESSION['formArray'][] = $_POST;
}
This will save each POST array as-is in the session.

I've got some code and it simply isn't working.  I thought it might be
because each time the form submits data, the array I'm storing
information in is being re-initialized.  If this is the case, I don't
have the multidimensional array I'm trying to get, but just a vector
array with the most recent submission data.


here are some thoughts...

sounds like you're just not keeping track of each iteration. i mean,
within the session variable you need to somehow differentiate between
each subsequent form submittal.
<?php

  $iteration = ++$_POST['iteration'];

  $_SESSION['post_data'][$iteration] = $_POST;

  // include $iteration in the post data
  // so that next time it comes around
  // it can be incremented.
  echo <<<QQQ
<form method="post" action="myself">
 ...
 <input type="hidden" name="iteration" value="$iteration" />
 ...
</form>
?>

you should then see a multi-dimensional array with
'print_r($_SESSION);'.
this code is untested and not very complete. ;) but maybe it will give
you some ideas?
hth,
chris.
