请帮助我如何添加类别过滤器最近我有机会重写Magento的分层导航标准功能。请求非常具体，因为客户机希望所有“过滤器”始终可见。例如，如果您希望按颜色过滤结果（假设您有黄色、绿色、红色、蓝色和洋红），则会过滤产品，但分层导航会显示所有过滤器。这样，客户可以重新筛选当前类别中的产品，而无需返回到类别视图

用于分层导航的文件位于app

/design/frontend/base/default/template/catalog/layer/

文件夹中。用于分层导航的文件是

view.phtml

——当我们点击一个类别时，它会显示所有的过滤器。用于活动状态的文件是

state.phtml

——当我们点击其中一个过滤器时，它负责结果——所以我们要编辑这个。因此，将

state.phtml

从base复制到您的包或主题中

这是state.phtml中的原始代码：

<?php $_filters = $this->getActiveFilters() ?>
<?php if(!empty($_filters)): ?>
<div class="currently">
    <p class="block-subtitle"><?php echo $this->__('Currently Shopping by:') ?></p>
    <ol>
    <?php foreach ($_filters as $_filter): ?>
        <li>
            <a href="<?php echo $_filter->getRemoveUrl() ?>" title="<?php echo $this->__('Remove This Item') ?>" class="btn-remove"><?php echo $this->__('Remove This Item') ?></a>
            <span class="label"><?php echo $this->__($_filter->getName()) ?>:</span> <?php echo $this->stripTags($_filter->getLabel()) ?>
        </li>
    <?php endforeach; ?>
    </ol>
    <div class="actions"><a href="<?php echo $this->getClearUrl() ?>"><?php echo $this->__('Clear All') ?></a></div>
</div>
<?php endif; ?>

Since we’re going to need url path of current category add this code before “currently” div block

<?php $obj = new Mage_Catalog_Block_Navigation(); ?>
<?php $_current_category=$obj->getCurrentCategory()->getUrlPath(); ?> //getting url path of current category
<?php $subs = $obj->getCurrentCategory()->getAllChildren(true); ?> //getting ids of subcategories of current category

即使您将属性设置为

Filterable（带结果）

您仍然需要对产品进行计数，以便只输出产品

计数>0的属性值

                                            <?php foreach($split as $color): ?>  //check out how many products have the same attribute value
                                                <?php if($color==$attr["value"]): ?>
                                                    <?php $count++;?>
                                                <?php endif; ?>
                                            <?php endforeach; ?>

                                        <?php endif;?>

                                    <?php endforeach; ?>

                                    <?php if($count>0):?>  // check if any product has that attribute value
                                        <li><a href="<?php echo $this->getUrl('').$_current_category ?>?color=<?php echo $attr["value"]?>" ><?php echo  $attr["label"]; ?></a></li>  // if not currently active filter make a link
                                    <?php endif; ?>

                                <?php else:?>
                                    <li class="current"> <?php echo $this->stripTags($_filter->getLabel()); ?></li>  // if currently active filter write out the label
                                <?php endif;?>
                        <?php endif; ?>
<?php endforeach;  ?>

<?php endforeach; ?> // ending the first for loop (foreach($filters as $filter))
                </ol>

            </dd>
    </dl>
    <a class="all" style="float:right;" href="<?php echo $this->getClearUrl()?>">All</a>    // show all products, return from current state back to category view
</div>
<?php endif; ?>

//检查有多少产品具有相同的属性值
//检查是否有任何产品具有该属性值
//如果当前未激活筛选器，请创建链接
//如果当前过滤器处于活动状态，请写出标签
//结束第一个for循环（foreach（$filters as$filter））
//显示所有产品，从当前状态返回类别视图

就这样。我们一直保持过滤器可见的任务已经完成，StackOverflow并不是一个教程服务。在请求帮助之前，请联机搜索并尝试执行某些操作。
 <?php foreach($attroptions as $attr): ?>   // get value and label of each attribute
