You just need a way to match the checkbox with the textarea. I would just run a counter when you create the form.
$output = qq~ <form><table> ~;
$counter = 1;
foreach $result (@$returned_results) {
$checkname = 'include_' . $counter;
$textname = 'summary_' . $counter;
$urlname = 'url_' . $counter;
$output .= qq~
<tr>
<td><input type="checkbox" name="$checkname"></td>
<td><textarea name="$textname"> yadda yadda </textarea></t
+d>
<td><input type="hidden" name="$urlname"></td>
</tr>
~;
$counter++;
}
$output .= qq~ </table></form> ~;
Now when you have a checked 'include_3' and 'include_87' you know that 'url_3' and 'summary_3' and 'url_87' and 'summary_87' need to go in the database.
