Displaying a confirmation message when options are saved

An important usability aspect of any user interface is to display an acknowledgment message when users have completed a task successfully. As you may have noticed in the previous recipe, WordPress does not provide any built-in user feedback after configuration data has been saved to the options table.

Getting ready

You should have already followed the Processing and storing plugin configuration data recipe and the resulting plugin should still be active on your development site. Alternatively, you can get the resulting code (ch3/ch2-page-header-output/ch2-page-header-output-v6.php) from the book's GitHub page. You should rename the ch2-page-header-output-v6.php file to ch2-page-header-output.php before starting this recipe.
