title: Drupal 7 hook_form_FORM_ID_alter() Submit
body: <p>I am developing a custom module and used <strong>hook_form_FORM_ID_alter</strong> method. I have provided option same as in block's configuration visibility settings for specific pages. I have also created a database table for my module. I am not getting any idea how the options selected by user should be stored in my table when submitted and also how the option selected for a particular menu link should be retained. I have added this functionality on menu item edit form. </p>
