Also show comment count in wp-admin/users.php

[novasource]

WordPress should also show each user's comment count in wp-admin/users.php.

An example use case is a client's blog with almost 200 users, the vast majority of which are old spammer accounts established before I added a Turing test to registration. I have no way to know which ones have no approved comments. If I could know that, I could probably reduce this list to 20 or so users.

WordPress forum posts that reference this need:
​http://wordpress.org/support/topic/267642
​http://wordpress.org/support/topic/207456
​http://wordpress.org/support/topic/241938
​http://wordpress.org/support/topic/298920 (this one says the feature was available in 2.5?)
​http://wordpress.org/support/topic/269956

Requesting 2.8.5 because this should be an easy change.

I attached a beta of the new features. Summary of changes:

• In template.php:
  • Added comments to users case in switch in get_column_headers.
  • To user_row:
    • Added $numcomments variable.
    • Added case switch to switch ($column_name) for new comments column. Note that this column doesn't use the same CSS classes as posts. I tried taking the same CSS classes and changing posts to categories, but the number was vertically centered.
    • Removed display of 0 from both posts and columns. This drastically helps usability where you have sparse matrixes--which will be the case if a lot of spammers got in--because a blank is a lot easier to spot than 0 against a set of integers that are >0.
• In user.php:
  • Added get_usernumcomments function. It's basically a copy of get_usernumposts with obvious modifications, including leaving out the get_private_posts_cap_sql at the end of the SQL statement. I inspected the referenced code and didn't think it's relevant to comments, although I admit I am not fully aware enough of the plugin ecosystem to know if I should have a different stance. Note that I assume the @since comment means this function has been present since the indicated version?

I couldn't clearly find if you prefer patch files or full files from external parties, so the full PHP is attached.

Other notes:

• Comments in the header appears to wrap in the middle of the word. Not sure what to do; probably needs CSS changes?
• Unlike the posts count link, comments count has no links to the comments of that user. I didn't see such a page. It would be a handy additional page.

Diff always, Full files are pretty much useless when reviewing changes, Many people will mearly glance at the diff rather than trying it out.

Milestone: All enhancements to current trunk

[novasource]

Patch files attached.

Removing my assignment because I am not familiar with Wordpress's development culture or processes.

Punting as no owner and no community testing in the three months that patch has been up. Thinking might be better as a plugin?

[novasource]

It would be unfortunate if such a simple and useful change had to be farmed out to a plugin.

I'd tend to agree that this is plugin material. You can always clean up your patches (looks like they're not generated properly; they could also be combined) and see if it gains traction for 3.0.

This feels like plugin material.

If the plugin is popular then it is possible that the code will get rolled into the core.

If we are missing hooks / filters which make it difficult to write a plugin to do this then pleas let us know and we will add them.

This is related to screen options which aren't properly hook-able (missed that already).

Hooks should be there to do this. If not, feel free to re-open.
