Array Posting Question? code snippet included

[acuradio]

I have a simple form on index.php. This $dAta array is contained on the page and has a few existing elements to it. I am trying to add an entry into the array from the $_POST. Any ideas?

Listed below is my code

<?php
$dAta = array(1 => "961204","961205","961206",);
?>

<FORM METHOD=POST ACTION="index.php">
<input name="field1" type="text" size="80" value="">
<INPUT TYPE=submit VALUE="Enter">

<?php
$d = count($dAta);
$d = $d + 1;
$dAta[$d] = $_POST['field1'];
?>

Have a look at :
www.php.net/serialize
www.php.net/unserialize

serialize() will transform an array into a string...

unserialize() will transform back that string to the original array...

So this way, you can pass the array in a hidden field...

Something like this :

echo '<input name="data" value="' . serialize($dAta) . '" type="hidden" />' . "\n";

Though you might want to use [man]addslashes/man to make sure that quotes and whatnot don't break your HTML.

Or, you could just store the seralized array in a session. Otherwise, you're letting the user see & manipulate the array (adding a possible security vulnerability).
