Hmmm...seems my loop isn't loopy enough...

I have a form, that has two name fields ($fname[1] and $fname[2]), and related email fields ($femail[1] and $femail[2]). The form then submits back to the same page, where a loop should kick off some stuff. Here's the code:

$items = 2;
$counter = 0;
for ($numitems=0; $numitems < $items; $numitems++) {
if (($fname[$numitems]!="") && ($femail[$numitems]!="")) {
// do some stuff;
$counter++;
$tally.="$fname[$numitems], ";
}
}
print("Counter: $counter<br />\n");
print("Tally: $tally<br />\n");


However, the loop only cycles once, with the data for [1]. I have verified that the $fname[2] and $femail[2] actually reach the script, but $counter only ends up being "1", and $tally only contains the value for $fname[1].

Fixed -

I changed
($numitems=0; $numitems < $items; $numitems++)
to
($numitems=0; $numitems <= $items; $numitems++)

and it works.

set $items=3;
then it will also catch the [2] arrays...

Pugz, I'm a little unclear what is happening here however a quick guess?

$numitems starts at 0 and will only count until 1 (< $items) so it's getting $fname[0] and $fname[1]. and you have them named [1] and [2].

Can some one switch forums on this?
