*/
class Mage_CatalogSearch_AjaxController extends Mage_Core_Controller_Front_Action
{
public function suggestAction()
{
if (!$this->getRequest()->getParam('q', false)) {
$this->getResponse()->setRedirect(Mage::getSingleton('core/url')->getBaseUrl());
}
$this->getResponse()->setBody($this->getLayout()->createBlock('catalogsearch/autocomplete')->toHtml());
}
}
三: block 数据处理返回 app\code\core\Mage\CatalogSearch\Block Autocomplete.php
/**
* Autocomplete queries list
*/
class Mage_CatalogSearch_Block_Autocomplete extends Mage_Core_Block_Abstract
{
protected $_suggestData = null;
protected function _toHtml()
{
$query = $this->helper('catalogsearch')->getQueryText();
$html = '';
if (!$this->_beforeToHtml()) {
return $html;
}
$suggestData = $this->getSuggestData();
if (!($count = count($suggestData))) {
return $html;
}
$count--;
$html = '<ul><li style="display:none"></li>';
foreach ($suggestData as $index => $item) {
if ($index == 0) {
$item['row_class'] .= ' first';
}
if ($index == $count) {
$item['row_class'] .= ' last';
}
$html .= '<li title="'.$this->htmlEscape($item['title']).'" class="'.$item['row_class'].'"><a href="'.$item['link'].'"><span class="title">'
.$item['title'] . '</span><span class="amount">'.$item['num_of_results'].'</span></a></li>';
}
$html.= '</ul>';
return $html;
}
public function getSuggestData()
{
if (!$this->_suggestData) {
$productTable = Mage::getSingleton('core/resource')->getTableName('catalog/category_product');
$query = $this->helper('catalogsearch')->getQueryText();
$collection = Mage::getResourceModel('catalog/category_collection')
->setStore(Mage::app()->getStore())
->addAttributeToSelect('name')
->addAttributeToSelect('url_key')
->addFieldToFilter('is_active', 1);
$counter = 0;
$data = array();
foreach ($collection as $item) {
$_data = array(
'title' => $this->getCategoryName($item),
'row_class' => (++$counter)%2?'odd':'even',
'link' => $item->getUrl(),
'num_of_results' => $this->__('%d products',$item->getProductCount())
);
if ($item->getName() == $query) {
array_unshift($data, $_data);
}
else {
$data[] = $_data;
}
if ($counter > 8) break;
}
$this->_suggestData = $data;
}
return $this->_suggestData;
}
public function getCategoryName($category)
{
$name = '';
foreach(array_reverse($category->getParentCategories()) as $item){
if($item->getLevel() == 1) break;
$name .= $item->getName().' ';
}
return $name;
}
}
