我有一个 Wordpress 商店设置，并且有一个钩子被调用来显示客户选择的产品选项。
钩子是：
wpsc_after_cart_widget_item_name
<?php echo wpsc_cart_item_name(); ?></a>
<span style="font-size: 10px; line-height: 0.06em;">
<?php do_action ( "wpsc_after_cart_widget_item_name" ); ?></td>
<td><?php echo wpsc_cart_item_quantity(); ?></td>
<td><?php echo wpsc_cart_item_price(); ?></td>
<td class="cart-widget-remove"><form action="" method="post" class="adjustform">
<input type="hidden" name="quantity" value="0" />
<input type="hidden" name="key"
value="<?php echo wpsc_the_cart_item_key(); ?>" />
<input type="hidden" name="wpsc_update_quantity" value="true" />
<input class="remove_button" type="submit" />
我无法弄清楚为什么它在购物车小部件中显示两次。我在网络上彻底搜索了过滤器挂钩、故障排除，甚至是用 jQuery 删除重复文本的丑陋方法，但一无所获。
任何帮助，将不胜感激。我的网站是http://www.a1decals.com/products-page。
我还不能发布图片，但这里有一个链接：http: //i134.photobucket.com/albums/q87/mad_stallion_2006/screen001-3_zpsa94e087b.jpg
更新：这是购物车的代码，您的代码插入到您告诉我它依赖的动作挂钩的上方和下方。
不知道是不是把代码放错地方了还是怎么了，我会继续挪动看看，但还是一头雾水。
很抱歉提出所有代码，但我不知道什么可能相关。
