Add custom class to WP_Posts_List_Table->single_row() output

[brandondove]

I am working on a custom post type implemention with some common custom meta information that I want to display in the post list. There is a need to indicate each post's status with a quick visual queue. Since there is no way to target a group of table rows that have certain characteristics, I resorted to highlighting the rows using jQuery.

Looking at the WP_Posts_List_Table class, it seems that this would be an easy problem to solve by simply adding a filter to the table row class list. I'm sure this same concept could also be extended to the other subclasses of WP_List_Table.

It'd probably make sense for us to use post_class() here.

New patch based on feedback from nacin

A simple plugin that adds a custom class to the single row on the post edit screen

The new patch uses get_post_class for WP_Posts_List_Table as nacin suggested. Duplicated classes on the table row were removed and author-(self|other) was moved into get_post_class for consistency.

Replying to nacin:

I'm sure I wrote this comment when I accepted the ticket ;)

We should keep the code out of get_post_class(), and instead pass in that value to get_post_class(), which takes an additional classes argument.

Use get_post_class() in the posts list table. props brandondove, fixes #18516.
