Question

I’m trying to find out what action hook/filter I can use to insert content on the admin “edit.php” page (i want to place a few links above the ‘posts’ table)? I’ve found “edit_form_after_title” and “edit_form_after_editor” (these do exactly what I want to do, but they are for posts.php, not edit.php).

Answer 1

If you just wanted to add to the post title link you could do something like this

if (is_admin()) {
    add_filter('the_title', function($title) {
        return $before_title . $title . $after_title;
    });
}

however, it doesn’t sound like you want to add text to the title link.

To add html after the title and before the actions links, you could do like this

if (is_admin()) {
    add_filter('post_row_actions', function($args) {
        // echo your custom content here
        return $args; // and dont forget to return the actions
    });
}

There is also page_row_actions for the page edit screen (post_row_actions is only for posts)

As far as adding stuff before the title, I don’t see a hook/filter to do that. See wp-admin/class-wp-posts-list-table.php line 463 function single_row if you want to look for yourself.
