Trying to create PHP script to modify tables

[Mikey7047]

OK, I just setup some forms today for my school, it is a form which submits to a database (MySQL). Essentially this database is going to be used as a "to-do" list. I have also managed to successfully export the database to a .xml for easy viewing. I later realized, I would need somehow to delete the row from the table once the task was completed...And I have no clue where to start since I have just begun learning PHP...I'm hoping someone around here can help me!

That is an idea of what I want the page to look like, when the submit button is pressed, it should get the id number from the form, then delete the id from the table.

How about something like this:

$sql = "DELETE FROM `tablename` WHERE `id` = '1'";
mysql_query($sql);
