 * Is there a way I can build a page for an end user to choose an item, from a list
   of items which can be saved and then referenced by a PHP function?
 * For example:
 * I need to provide Gravity Forms a form recipient email address based on the oncall
   user who’s been selected in the front end of the site.
 * So using the filter below, I’d need to write a function that get’s the current
   oncall persons info from a page that the client has chosen from a list.
 * `add_filter( 'gform_notification', 'your_function_name', 10, 3 );`
 * I’m not asking how to write the function, but rather **how do I create a list
   where the selection can be stored and retrieved by a function**?
 * I hope this makes sense. I’m new to all this 😀

 * I have done something like this using a custom page template. It would fill in
   a form and save changes to that form. The plugin which showed me the basic techniques
   was:
    `https://wordpress.org/plugins/wp-csv-to-database/` It showed me how to
   display tables, forms and controls, how to respond to form actions.
 * Once you have your list you can also access it using shortcodes, details here:

 * Thanks Ross!
 * Did you have to reverse engineer the plugin?
 * I’ll install it and take a look 🙂

 * I wouldn’t think that “reverse engineering” is appropriate under the GPL and 
   provision of source code.
    Yes, I read the plugin files, examined how the forms
   handled the display and update phases, how to use SQL and so on. In my own code
   I acknowledge this plugin as providing guidance.

 * I wasn’t trying to be insulting. I meant reverse engineering in a good way. I’m
   new to development. Sorry if I offended.
