title: foreach in wordpress
body: <p>I am having some problems to make the following code to work in my side bar of wordpress:
  <code></p>
  
  <pre><code>            $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 = $current_year;
                      echo '&lt;li&gt;&lt;a href="'.get_year_link($current_year).'"&gt;'.$current_year.'&lt;/a&gt;&lt;/li&gt;';
                  }
                  $month_post = 0;
                  foreach ($post as $post_monthly) : 
                         setup_postdata($post_monthly);  
                         $current_month = get_the_time('m');
                          if ($current_month != $month_post){
                                 $month_post =$current_month;
                                 echo '&lt;li&gt;&lt;a href="'.get_year_link($current_month).'"&gt;'.$current_month.'&lt;/a&gt;&lt;/li&gt;';
                          }
  
                          foreach ($post_monthly as $post_title) : 
                                  setup_postdata($post_title);
  
                                  echo '&lt;li&gt;&lt;a href="'.get_permalink().'"&gt;'.the_title().'&lt;/a&gt;&lt;/li&gt;';
                          endforeach;
  
                  endforeach;
  
              endforeach;
  
              wp_reset_postdata();
  </code></pre>
  
  <p></code>
  With this code I am trying to display the following:</p>
  
  <ul>
  <li>2012<br>
  -May
  <ul>
  <li>Lorem ipsum</li>
  <li>Lorem ipsum</li>
  <li>Lorem ipsum</li>
  </ul></li>
  </ul>
  
  <p>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() " </p>
  
  <p>I have checked so many times this code, I just don't seem to see the problem.</p>
  
  <p>Can anyone see something that I am missing, It will be highly appreciated.
  Thanks!</p>
