TL;DR: This article outlines the code needed to add a custom link on the All Posts screen that uses a custom piece of post metadata.

Note: A few months ago, I wrote an article on how to add a custom view to the All Posts screen. This article is not all together the same, but not all together different. Think of it as a more detailed and perhaps for more practical implementation of the concept.

Assume that you have a standard post type or a custom post type and you’re going to simply filter by a headline that you define using a mechanism that allows you to save data to the post_metadata table.

For example, let’s say that you have a post and it as a piece of meta data with:

• a meta_key with the value of article_attribute
• a meta_value with the value of headline

And you want to use this information to add a new Headlines link that automatically filters everything out except articles with that metadata.

Here’s how to do it.

TL;DR: If you’re looking for an easy way to sort WordPress posts by date (be it descending or ascending) in the administration area without having users click on the Date column header, you can do so through the use of the pre_get_posts filter that provides a reference to the instance WP_Query running on the page.

For examples in code on how to do that, check out the rest of the article.
