I have to show 3 differents template to a person and then say to him: "Please, choose one of these templates and I will use it for your web site"

So the question is: Have I to install 3 differents WP test websites (one for each templates) or can I install only one WP website and install on it 3 templates and give to him a differents links (one for a specific installed template)?



  • Do you mean templates, or themes? Is this like a demo site where you can 'test' against several different themes? Commented Aug 5, 2013 at 8:41
  • @Stephen Harris I mean themes, yes I need a demo site to show 3 different themes Commented Aug 5, 2013 at 9:09

    Depends on how dramatic the template changes are. I've installed three themes on one install and then used a theme switcher plugin to switch between them until the client chooses one.

I've done for this myself using the plug-in theme switcher: http://wordpress.org/plugins/theme-switcher/ (yes, it hasn't been edited in 2+ years).

These theme stores a cookie in the browser indicating which theme the user has selected (themes are displayed as a drop-down / link list widget - and selecting a theme changes the cookie and redirects you to the home page).

You can dynamically change the theme with the stylesheet filter:

function wpse109022_change_theme_name( $stylesheet ){
    //Change stylesheet to appropriate theme (based on cookiee for example)
    //$stylesheet should be the theme 'name', e.g. 'twentytwelve'
    return $stylesheet;
add_filter( 'stylesheet', 'wpse109022_change_theme_name' );

Please note Theme Switcher also uses the template filter, to do the same thing. I believe this is for backwards compatibility. (2.5??)

//add_filter( 'template', 'wpse109022_change_theme_name' );

See source of theme switcher for more details

Caveat: one problem is that WordPress doesn't remember templates between themes. For example:

  • Create page and choose template A from your theme
  • Change theme
  • Select template from the new theme and re-save the page
  • Switch back to original theme. The page no longer has template A

If you're using page templates you'll want WordPress to remember which template to use for which theme. I wrote a plug-in for this: http://wordpress.org/plugins/remember-my-template/

It essentially does the following:

  • Every time a page is saved, store the template as meta data with key _wp_page_template_{theme-name}
  • Filter the page's template via get_post_metadata filter and replace it with the appropriate template based on the theme.
