autocomplete

一：base\default\template\catalogsearch form.mini.phtml

//<![CDATA[

var searchForm = new Varien.searchForm('search_mini_form', 'search', '<?php echo $this->__('Search entire store here...') ?>');

searchForm.initAutocomplete('<?php echo $catalogSearchHelper->getSuggestUrl() ?>', 'search_autocomplete');

//]]>

</script>

二：提交到croller app\code\core\Mage\CatalogSearch\controllers AjaxController.php

/**

* Catalog Search Controller

* @category Mage

* @package Mage_CatalogSearch

* @module Catalog

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;

}
