I would like to use the user name of a logged in user in JavaScript without server side implementation.

Since I'm using a cache plugin (WP Super Cache), I don't want to place a user name into the generated HTML output of WordPress. But I would like to use it to fill a contact form, if the user is already logged in.

Is there a way without a separate AJAX request?

  • FWIW W3 Total Cache appears to support something like this using special tags in the template: justinsilver.com/technology/wordpress/… May 8, 2020 at 4:07

  • Only if the user has been to /wp-admin, and you still need an AJAX request to get the user name. May 8, 2020 at 14:02
  • Can you clarify why you're trying to avoid a server-side implementation? If it's simply to avoid the caching, but you're otherwise able to make PHP changes, you can pass the username to your Javascript using this technique: blog.wplauncher.com/… May 13, 2020 at 0:58
