How Can I add Fields in wp-option table?

Question

I want to activate my plugin and I want to create fields in "wp_option" table. How can I do that?

Answer 1

If you just want to create a field, add_option() will do just fine, but I would strongly recommend using update_option() instead, as it tends to be the better choice for most applications.

Answer 2

Refer to the Codex entry for Plugin Development - specifically the WordPress Options Mechanism section. See also: Creating Options Pages, and especially Settings API.
