Variable Combinations

[vaiod]

Okay... I would like to combine two variables but not like most of the other examples in this forum... Here is the concept.

...
for ($i = 1;$i <= 9;$i++) {
echo("<input type=text value=\"$height[$i]\" name=height$i><br>");
}
...

As a result I would have 9 textboxes named height1, 2, 3 etc...

The form initially would show no values in the textboxes but if 2 of 9 are filled out and submitted (requires all 9) it would error and re-display the form with the 2 values entered from before.

I could just code the entire thing 9 times but that makes no sense.

Kind of a weird use I know... anybody have any ideas?

Thanks Much,
Eric

try ${height}$i
instead of
$height[$i]

Another idea would be:

for ($i = 1;$i <= 9;$i++) {
	$temp = "height" . $i;
	echo "<input type=\"text\" value=\"{$$temp}\" name=\"{$temp}\"><br>";
}

though generally it would be better to use height[N] instead of heightN for your names.

Thanks for the feedback I really appreciate it...

try ${height}$i
This didn't work but the other solution did...

Thanks again to laserlight and drew010.
