return form results using array 1

[mrsbean]

I want to return the contents of a multi-select list box from a form using an array.

$size = count ($_REQUEST['AreasOfInterest']);

$p1 = $_REQUEST['AreasOfInterest[]'];

echo "<P>size: $size </p>";
$x = 0;

while ($x < $size) {
echo "<p> Array Value $x = $p1[$x] </p>";
$x++;
}

Arrays scare me - not really sure how they work. The code above returned the following:

size: 4

Array Value 0 =

Array Value 1 =

Array Value 2 =

Array Value 3 =

I'm not getting the text value I was seeking following the equal sign. What am I doing wrong?

Thanks in advance.

The interior brackets in this line:

$p1 = $_REQUEST['AreasOfInterest[]'];

don't make sense. If you mean to reference an element of $_REQUEST['AreasOfInterest'], then that is done as $_REQUEST['AreasOfInterest'][0], $_REQUEST['AreasOfInterest'][1], $_REQUEST['AreasOfInterest'][2], etc.

Also, I recommend strongly against using $_REQUEST. It is more secure to reference $_GET and $_POST for GET- and POST-method input, respectively. Since $_REQUEST is an amalgam of $_GET, $_POST and $_COOKIE, $_REQUEST shares some of the problems of setting register_globals() to "on". See

Omit the sharp brackets [ignore][][/ignore] from your request, then it should work :

$p1 = $_REQUEST['AreasOfInterest'];
