Question

I am having some problems to make the following code to work in my side bar of wordpress:

            $the_query = get_posts( $args );


            $year_post = 0;
            foreach ($the_query as $post) : 
                setup_postdata($post);
                $current_year = get_the_time('Y'); 
                if( $current_year != $year_post ) {
                    $year_post = $current_year;
                    echo '<li><a href="'.get_year_link($current_year).'">'.$current_year.'</a></li>';
                }
                $month_post = 0;
                foreach ($post as $post_monthly) : 
                       setup_postdata($post_monthly);  
                       $current_month = get_the_time('m');
                        if ($current_month != $month_post){
                               $month_post =$current_month;
                               echo '<li><a href="'.get_year_link($current_month).'">'.$current_month.'</a></li>';
                        }

                        foreach ($post_monthly as $post_title) : 
                                setup_postdata($post_title);

                                echo '<li><a href="'.get_permalink().'">'.the_title().'</a></li>';
                        endforeach;

                endforeach;

            endforeach;

            wp_reset_postdata();

With this code I am trying to display the following:

• 2012
  -May
  • Lorem ipsum
  • Lorem ipsum
  • Lorem ipsum

It display 2012, May, but when it comes to display the titles of the post I am getting the following error: “Warning: Invalid argument supplied for foreach() ”

I have checked so many times this code, I just don’t seem to see the problem.

Can anyone see something that I am missing, It will be highly appreciated.
Thanks!

The return value of get_posts() is an array of objects. So then, your $post contains an object, not an array.
