Concatenating

[Anon]

I have a long order form with a text box in each row for quantity of items.

<form method=post>
<tr>
<td><input type=text name=row1 size=5></td>
</tr>
<tr>
<td><input type=text name=row2 size=5></td>
</tr>
</form>

I'm trying to loop through and print out ones that have values. What am I doing wrong below:

<?php

for ($i = 0; $i < 3; $i++) {

$thisRow = $row.$i;

	if ($thisRow) {
		echo $thisRow;
	} 

}	

?>

When I set $thisRow = $row1, it correctly gives me the value I entered in the form.
Thanks,
Scott

I meant to add, the results I am getting with the above code are:
12

instead of the value entered in the text field. It's just spitting the $i values.

You are trying to use "variable variables".

Try this:
$thisRow = ${"row".$i};

Also, read the manual for other useful tricks on variable variables.
