Wordpress, add custom button on post type list page

Question

I am trying to add custom button on top of post type page like this image

Is there any filter or action I can use to add custom button there?

Thanks

If you are using the class WP_Lists_table (and you should) then this is the right way to do it:

add_action('manage_posts_extra_tablenav', 'add_extra_button');
function add_extra_button($where)
{
    global $post_type_object;
    if ($post_type_object->name === 'shop_order') {
        // Do something
    }
}

Digging into WordPress core code i did not find any hook or any filter for that buttonm you can also see that code from line no 281 to line number 288 . But you can add your button here according to this filter.

add_filter('views_edit-post','my_filter');
add_filter('views_edit-page','my_filter');

function my_filter($views){
    $views['import'] = '<a href="#" class="primary">Import</a>';
    return $views;
}

Hope it helps you.

Unfortunately there is no hook called after showing the "Add New" button. The closest possible place to add anything without using javascript is below the title and "Add new" like this:

In my example I added a button to my custom post type "Event" using the hook "edit_form_top":

add_action('edit_form_top', 'add_custom_button');

function add_custom_button($id){
    if ($post->post_type != 'event') return false;
    echo('<button>Custom button</button>');
}
