Mandatory plugins in sage theme

Hi sage community,

I would like to make ACF pro a mandatory activated plugin for my theme. When it is not active, the user should not be able to do things in wp-admin. Is there a mechanism for doing this without manual if conditions?

Thank You!

If you are using Bedrock, just install it into app/mu-plugins and it wont be able to be deactivated.

Great! Thank you for that quick answer.

To manage this in composer directly you can add extra installer-paths for the plugins.

"extra": {
    "installer-paths": {
      "web/app/mu-plugins/{$name}/": [
      "web/app/plugins/{$name}/": ["type:wordpress-plugin"],
      "web/app/themes/{$name}/": ["type:wordpress-theme"]

Here I’ve used the package name for their acf pro package

Composer provides an example with akismet here

When it comes to actually developing with ACF as an MU plugin, things got a little weird for me. Though I don’t recall exactly what, it’s been a while. Anyways, if that happens to you, you could alternatively hide the plugin from the plugins list and hide the settings panel from the admin. There are lots of instructions for this online.
