Think about it...
You would not <?php echo $_REQUEST; ?> and expect to get the value of any form
field would you. No, you wouldn't.
Given the following form...
<form>
Title<input type="text" name="title" value="" /><br />
Subject<input type="text" name="subject" value="" /><br />
<input type="submit" name="submit" value="Send it!" />
</form>
on the processing page, I would access those variables by writing the following.
echo $_REQUEST['title'];
echo $_REQUEST['subject'];
With that said, going back to your issue, you would do this:
if ( $_REQUEST['painDesc'] && count($_REQUEST['painDesc']) ) {
foreach($_REQUEST['painDesc'] as $key => $val) {
echo "{$key}:{$val}<br />";
}
}
