Passing data between PHP and MySQL database?

[MacMorag]

I have added a drop-down menu to the reply form, which has three options - "A", "B" and "C". Whenever someone replies they must select either of the three options.

I have also created a new field in the "post" table in the database. This field is called "option", and is used to record whether A, B or C was selected when the post was submitted.

How do I pass the selected option from the reply form and place it in the "option" field in the database.

e.g. When the post is submitted by the user, they select option A. How do I place "A" in the "post"table of the database.

Thanks.
