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
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>(责任编辑:最模板) |
