Magento: 如何对产品进行分目录的产品搜索

 

 

In "advanced search" feature, searching product by category is not the default setting.  But we can do this by modifying the foloowing files:

 

app/code/core/Mage/CatalogSearch/Block/Advanced/Form.php

app/code/core/Mage/CatalogSearch/Model/Advanced.php

app/design/yourdesign/yourdesign/template/catalogsearch/advanced/form.phtml

 

 

 

At the bottom of app/code/core/Mage/CatalogSearch/Block/Advanced/Form.php we can add following codes:

 

public function getStoreCategories()

    {

        $helper = Mage::helper('catalog/category');

        return $helper->getStoreCategories();

    }

 

 

In app/code/core/Mage/CatalogSearch/Model/Advanced.php, replace the getSearchCriterias() by following functions:

 

 

 

 public function getSearchCriterias()

 

     {

     $search = $this->_searchCriterias;

              /* display category filtering criteria */

         if(isset($_GET['category']) && is_numeric($_GET['category'])) {

         $category = Mage::getModel('catalog/category')->load($_GET['category']);

         $search[] = array('name'=>'Category','value'=>$category->getName());

      }

      return $search;

     }

 

 

Replace the getProductCollection() by following function:

 

 public function getProductCollection(){

    if (is_null($this->_productCollection)) {

        $this->_productCollection = Mage::getResourceModel('catalogsearch/advanced_collection')

        ->addAttributeToSelect(Mage::getSingleton('catalog/config')->getProductAttributes())

        ->addMinimalPrice()

        ->addStoreFilter();

        Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($this->_productCollection);

        Mage::getSingleton('catalog/product_visibility')->addVisibleInSearchFilterToCollection($this->_productCollection);

        /* include category filtering */

        if(isset($_GET['category']) && is_numeric($_GET['category'])) $this->_productCollection->addCategoryFilter(Mage::getModel('catalog/category')->load($_GET['category']),true);

        }

        return $this->_productCollection;

} 

 

 

 

In page app/design/yourdesign/yourdesign/template/catalogsearch/advanced/form.phtml, find the codes as following:

 

 

 

   <input name="<?php echo $_code ?>" id="<?php echo $_code ?>" value="<?php echo $this->htmlEscape($this->getAttributeValue($_attribute)) ?>" title="<?php echo $this->htmlEscape($this->getAttributeLabel($_attribute)) ?>"  class="input-text <?php echo $this->getAttributeValidationClass($_attribute) ?>" type="text" />

            <?php endswitch; ?>

        </li>

        <?php endforeach; ?>

 

 

at the bottom of this piece of codes, add following codes:

 

 

 

         <li>

<label for="category_search_field">Search by Category:</label>

<select name="category" id="category_search_field">

<option value="">-- Any Category --</option>

<?php foreach ($this->getStoreCategories() as $_category): ?>

<?php if($_category->hasChildren()): ?>

<option class="parent-cat" value="<?php echo $_category->getId(); ?>"><?php echo $_category->getName();?></option>

<?php foreach ($_category->getChildren() as $subcategory):

if($subcategory->getIsActive()) : ?>

<option value="<?php echo $subcategory->getId(); ?>"<?php echo ($this->getRequest()->getQuery('category') == $subcategory->getId() ? ' selected="selected"': "") ?>><?php echo $subcategory->getName(); ?></option>

<?php endif; endforeach; ?>

<?php elseif($_category->getIsActive()): ?>

<option value="<?php echo $_category->getId(); ?>"><?php echo $_category->getName();?></option>

<?php endif; ?>

<?php endforeach ?>

</select>

</li>
