I have created a form. On success of the form, I am redirecting the user the their dashboard. Now, I want to be able to show a success message/notice on the dashboard.
What is the convention to show such messages ?
When you redirect the user to the admin dashboard pass on a GET variable named "success_notice", for example. So you get a URL like this:
With that setup, just add the code that shows the success message on the dashboard only if that GET variable is set.
