i want to switch the theme of my WP website automatically by random for my users in order to do different A/B testing actions. switch_theme is not working cause that changes the theme in the database.
But i want to do this for each user by random without changing the general themesetting in WP. Like the function WP provides when previewing a theme. How can i do that? I do not need help with the randomize function etc. I just need a hint how to switch the theme for a usersession.
A plugin is not a solution, cause there is none i could use to fulfill my requirements for the A/B test. I need to program individually for my needs.
Thanks in advance for your help! René
