Actually, if you make the names in the form resemble array variables,
this can be greatly simplified.
Something similar to the following might be what you are looking for:
<input type="text" name="item[0]">
<input type="text" name="item[1]">
when the form is passed to the next script, there will be a single
variable called $item - and it will be an array with two values.
This is one of the neater features of PHP... I would recommend generating
the input fields using something like the following:
for ($loop=0; $loop < $num_needed; $loop++) {
echo "<input type=\"text\" name=\"item[$loop]\"><br>";
}
in the result script you can then traverse the passed array $item
with a foreach loop (if you are using PHP4). Something like the following
could possibly work.
foreach($item as $key=>$value) {
echo "Index #$key = $value<br>";
}
