Tools > "Repair site tracking site icons" generates PHP Fatal error when not on Multisite

[slaFFik]

If you open Tools > BuddyPress page in /wp-admin/tools.php?page=bp-tools and try to run "Repair site tracking site icons/blog avatars synchronization." operation while NOT being on WP Multisite - the action will generate a fatal error:

PHP Fatal error:  Uncaught Error: Call to undefined function get_sites() in trunk\wp-content\plugins\buddypress\src\bp-core\admin\bp-core-admin-tools.php:337

It looks like this was introduced in BP 7 (see #8384).

Multisite-related operation "Repopulate site tracking records." works fine because it uses a function bp_blogs_record_existing_blogs() which does all the proper is_multisite() checks.
And bp_admin_repair_blog_site_icons() used in a failing operation calls get_sites() directly without safety checks first.

I've attached a patch that implements the easiest solution to this problem - on non-MS site display a "Failed" message, similar to bp_admin_repair_blog_records() function.
We could add get_sites() function into our bp-core-wpabstraction.php file, but I do think this would be a bad idea.

Thanks for catching this issue and for the patch @slaFFik 👌. I believe we should only include this tool for Multisite configs.

In this case, I suggest to leave the improvement I made in the 1st patch, but also hide the checkbox completely if not on Multisite. So direct call to a function will return an expected array with a "Failed" text, but by default, the checkbox won't be displayed on the Tools page at all on a regular WP installation. Sounds good?

Sounds good 👌 Let’s have this in 😉

In 12826:

Tools: add WP MultiSite checks for "Repair site tracking site icons" operation

On regular sites checking and running the "Repair site tracking site icons" operation on the Tools > BuddyPress page generates a fatal error due to the get_sites() function usage, which is MultiSite specific. So, hide the operation on non-multisite and properly return an error when ran directly.

Fixes #8414 (Trunk)
