How it works...
This recipe shows how we can leverage options arrays to create multiple sets of options simply by creating the name of the options array on the fly. Instead of having a specific option name in the first parameter of the get_option function call, we create a string with an option ID. This ID is sent through as a URL parameter on the configuration page and as a hidden text field when processing the form data.
The rest of the code is very similar to the other examples that we have seen in this chapter, since the way to access the array elements remains the same.
