foreach закрывается после первого значения, затем отображаются оставшиеся значения

Question

Я написал WordPress виджет, который перечисляет категории блога в теге. Первоначально код, который я написал, работает, и вы можете выбрать значение, а когда вы нажимаете сохранить, виджет отображает правильную информацию в интерфейсе. Однако после нажатия кнопки «Сохранить» при перезагрузке массива он выглядит следующим образом:

<select name="widget-cheer_recent_posts[7][cat]" id="widget-cheer_recent_posts-7-cat" class="widefat"></select>

<option value="72" id="Elite">Elite</option>
</p>
<option value="96" id="Featured">Featured</option>
<option value="70" id="Junior Varsity">Junior Varsity</option>
<option value="105" id="JV">JV</option>
<option value="67" id="Mixes">Mixes</option>
<option value="97" id="promo">promo</option>
<option value="99" id="Samples">Samples</option>
<option value="1" id="Uncategorized">Uncategorized</option>
<option value="71" id="Varsity">Varsity</option>

Я не уверен, как это происходит, так как выпадающий список загружается правильно с первого раза, и только после сохранения и перезагрузки AJAX в WordPress происходит сбой. Вот код для виджета:

define ('CHEER_PLUGIN_DIR', dirname( plugin_basename( __FILE__ ) ));
define ('CHEER_PLUGIN_URL', plugins_url() . '/' . CHEER_PLUGIN_DIR);

class cheer_recent_posts extends WP_Widget {


    /** constructor */
    function cheer_recent_posts() {
        parent::WP_Widget(false, $name = 'Cheer Samples');  
    }

    /** @see WP_Widget::widget */
    function widget($args, $instance) { 
        extract( $args );
        global $posttypes;

        global $cats;
        $title          = apply_filters('widget_title', $instance['title']);
        $cat            = $instance['cat'];
        $number         = apply_filters('widget_title', $instance['number']);
        $offset         = apply_filters('widget_title', $instance['offset']);
        $thumbnail_size = apply_filters('widget_title', $instance['thumbnail_size']);
        $thumbnail      = $instance['thumbnail'];
        $posttype       = $instance['posttype'];
        ?>
              <?php echo $before_widget; ?>
                  <?php if ( $title )
                        echo $before_title . $title . $after_title; ?>

                                // get the category IDs and place them in an array
