Add content in custom post type page after the title and before columns

Question

I found here on WPSE that you can add content before post title in the post page, and in custom post type pages

    add_action( 'load-edit.php', function(){

       $screen = get_current_screen();

        // Only edit post screen:
       if( 'edit-reservation' === $screen->id )
       {
            // Before:
            add_action( 'all_admin_notices', function(){
                echo '<p>Greetings from <strong>all_admin_notices</strong>!</p>';
            });

        }
    });

Which works in my reservation custom post type. But I'm wondering if it's possible to output content after the title, but before table with custom post types?

Answer 1

You could try to "hijack" the following filter in the WP_List_Table class:

/**
 * Filter the list of available list table views.
 *
 * The dynamic portion of the hook name, `$this->screen->id`, refers
 * to the ID of the current screen, usually a string.
 *
 * @since 3.5.0
 *
 * @param array $views An array of available list table views.
 */
 $views = apply_filters( "views_{$this->screen->id}", $views );

Example

For the edit-post screen, the filter is views_edit-post:

/**
 * Display HTML after the 'Posts' title
 * where we target the 'edit-post' screen
 */
add_filter( 'views_edit-post', function( $views )
{
    echo '<p>Greetings from <strong>views_edit-post</strong></p>';

    return $views;
} );

and this will display as:

You can do it with JavaScript.

add_action( 'all_admin_notices', function(){
    echo '<script>jQuery(document).ready(function($) {  $( "<p>Greetings from <strong>all_admin_notices</strong>!</p>" ).insertAfter( ".subsubsub" );});</script>';
} );
