Foreach在foreach里面

Question

I need help with a foreach within a foreach. I'm using the Wordpress plug-in, Advanced Custom Fields to create Repeater Fields inside of repeater fields. I'm then displaying (or attempting to display) them on the frontend outside the main loop using the code below:

 <?php
            //Loop Through Days and Sights
              $days = get_field('day_and_highlights');
              $n = 0;

              if($days){
                echo '<div>';
                  foreach($days as $day){ 
                    $n++;
                    echo '<h2> Day ' . $n . ': ' . $day['destination_dropdown'] . '</h2><br/>';
                    //Loop through Attractions
                    <?php
                    $attractions = get_field('attraction_list');
                    if($attractions){
                        echo '<ul class=\"list_attractions\">';
                        foreach($attractions as $attraction){
                            echo '<li class=\"single_attraction\"><p>' . $attraction['add_attraction'] . '</p></li>';
                        }; //end foreach
                        echo '</ul>';
                    }; //endif 
                  };
                echo '</div>';
              };
            ?>

The first foreach echo's everything spot on. The inner foreach doesn't do jack. I can't get it to do anything.

You have an extra php tag:

             //Loop through Attractions
             <?php
                $attractions = get_field('attraction_list');
                if($attractions){

Try removing it.

Also, your IF and FOREACH statements should not end in semicolons:

                }; //endif
