我想在我的类别小部件中的类别旁边添加一些自定义项目符号，因此我创建了一个新的小部件，并添加到新的html和类中，以便我可以更改它的外观。不幸的是，由于某种原因，我的小部件在整个商店页面以及它需要的位置（在类别列表/侧栏中）添加了一个指向我最后一个类别的链接。虽然一切似乎都很正常，但到处都是空的a标签却把其他元素的造型搞得一团糟，增加了额外的空间，让事情变得一帆风顺。

Here is my full widget code:

class mdk_wpcat_widget extends WP_Widget {
// Set up the widget name and description.
public function __construct() {
    $widget_options = array( 
        \'classname\' => \'mdk_wpcat_widget\', 
        \'description\' => \'Custom MDK Woocommerce Category Widget\' 
        );
    parent::__construct( \'mdk_wpcat_widget\', \'Woo Cat Widget\', $widget_options );
}

// Create the widget output.
public function widget( $args, $instance ) {
    $title = apply_filters( \'widget_title\', $instance[ \'title\' ] );

    // before and after widget arguments are defined by themes
    //$blog_title = get_bloginfo( \'name\' );
    //$tagline = get_bloginfo( \'description\' );
    echo $args[\'before_widget\'] . $args[\'before_title\'] . $title . $args[\'after_title\']; 

    // Custom Woo Category Output
    $args = array(
        \'number\'     => $number,
        \'orderby\'    => \'menu_order\',
        \'order\'      => \'ASC\',
        \'hide_empty\' => $hide_empty,
        \'include\'    => $ids
    );
    //Hides "film" category by ID
    $args[\'exclude\'] = \'72\';

    $product_categories = get_terms( \'product_cat\', $args );

    $count = count($product_categories);
     if ( $count > 0 ){
         echo \'<ul class="shop-categories">\';
         foreach ( $product_categories as $product_category ) {
            echo \'<li class="shop-category \' . (( $product_category->name == single_cat_title(\'\', false) )?"active-cat":"") . \'"><a href="\' . get_term_link( $product_category ) . \'"><span class="bulletpoint"></span><span class="category-title">\' . $product_category->name . \'</span></li>\';

         }
         echo \'</ul>\';
     }

    echo $args[\'after_widget\'];
}

// Create the admin area widget settings form.
public function form( $instance ) {
    $title = ! empty( $instance[\'title\'] ) ? $instance[\'title\'] : \'\'; ?>    
    <p>
      <label for="<?php echo $this->get_field_id( \'title\' ); ?>">Title:</label>
      <input type="text" id="<?php echo $this->get_field_id( \'title\' ); ?>" name="<?php echo $this->get_field_name( \'title\' ); ?>" value="<?php echo esc_attr( $title ); ?>" />
    </p><?php
}

// Apply settings to the widget instance.
public function update( $new_instance, $old_instance ) {
    $instance = $old_instance;
    $instance[ \'title\' ] = strip_tags( $new_instance[ \'title\' ] );
    return $instance;
  }
}

// Register the widget.
function mdk_wpcat_load_widget() { 
register_widget( \'mdk_wpcat_widget\' );
}
add_action( \'widgets_init\', \'mdk_wpcat_load_widget\' );

谢谢你的帮助！
