Here is the function that I use to display CPT in the “At a glance” widget
add_action( 'dashboard_glance_items', 'cpad_at_glance_content_table_end' );
function cpad_at_glance_content_table_end() {
$args = array(
'public' => true,
'_builtin' => false
);
$output="object";
$operator="and";
$post_types = get_post_types( $args, $output, $operator );
foreach ( $post_types as $post_type ) {
$num_posts = wp_count_posts( $post_type->name );
$num = number_format_i18n( $num_posts->publish );
$text = _n( $post_type->labels->singular_name, $post_type->labels->name, intval( $num_posts->publish ) );
if ( current_user_can( 'edit_posts' ) ) {
$output="<a href="https://wordpress.stackexchange.com/questions/138812/edit.php?post_type=" . $post_type->name . '">' . $num . ' ' . $text . '</a>';
echo '<li class="post-count ' . $post_type->name . '-count">' . $output . '</li>';
}
}
}
This make the text clickable as link. Hope this helps
