I have a polygon on a web page and a delete button. The polygon is saved in the database in one table and in another table, the coordinates of polygon (latitude,longitude) are saved. When I click the delete button, the polygon in the webpage gets deleted as well as the polygon in database. However the points are not getting deleted.

I used this code:

mysqlquery("DELETE FROM polygon WHERE ID=".$GET['ID']."") or die(showsqlerrors(mysql_error()));

I also used:

mysqlquery("DELETE FROM points WHERE ID=".$GET['ID']."") or die(showsqlerrors(mysql_error()));

But it did not work.

Could anyone help me out?
