Re: form and arrays[]

It's possible to have form variables submitted as an array. In your
HTML, just add [] after the variable name (like a PHP array). So, to
draw the form you might have something like this:

for($i = 0; $i < 12; $i++) { ?>
<input type="text" name="description[<?=$i?>]"/>
<input type="text" name="amount[<?=$i?>]"/>
<? } ?>

Of course you'll need to adjust the <?=$i if you don't have short open
tags enabled.

Once the form has been submitted, $_POST['description'] will be an
array rather than a single value. So, you can reference
$_POST['description'][2] if you wanted.

To turn these variables into a string, you could do something like
this:

$str = '';
for($i = 0; $i < 12; $i++) {
$str .= $_POST['description'][$i] . "," . $_POST['description'][$i]
.. "\n";
}

.
