Excuse the last post, I didn't have all the code it there. I have a table listing items in a database, and have a delete button next to each item, and I want to be able to click on the delete and delete only that record in the database and then reload the page where it would display the updated information. Here is part of the code I have.You have a lot of detail for folks to analyze just to give you an answer. If I get the gist of your question, here is the genesis of an approach. Put something like this in your loop that generates the table rows. The checkbox can be anywhere in the row that looks good. echo "<input type=\"checkbox\" name=\"row$i\" value=\"$value\">"; $i++; Then when you process your $_POST, you'll see all the $_POST[rowx] {"x" is the row number} that were checked by the user.// list elements one by one until there are no more in the database while ( $row=mysql_fetch_array($result2) ) { if ($row[range] != "") { echo " <form action=".$_SERVER['PHP_SELF']." method=\"post\" name=\"deleteRange\"><tr class=\"trlist\"> <td>$row[id]</td> <td>$row[range]</td> <td align=\"right\"><input type=\"submit\" name=\"deleteRange\"value=\"Delete\" /></td></tr> </form> "; } } echo "</table>"; echo " <br /> <form action=".$_SERVER['PHP_SELF']." method=\"post\" name=\"addrange\"><table class=\"nolist\"> <tr> <td>Add Range: $row[id]</td> <td><input type=\"text\" name=\"name\" size=\"53\" tabindex=\"9\" /></td><td align=\"right\"><input type=\"submit\" name=\"addRange\"value=\"Add Range\" /></td></tr></table> </form>";}elseif (isset($_POST['deleteRange'])) {$query = "delete from district.ip_range where id = $row[id]"; mysql_query($query, $link) or die (mysql_error()); echo "Record ".$row[id]." has beed deleted."; }They key I am using to find the record I want to delete is the the $row[id], but that is out of the scope of where the variable is set. Is there a way to set a variable so that it goes outside the scope?
