magento--搜索功能添加分类选项！

magento的搜索是没有分类条件的，我们可以给他加上这个条件，在综合站搜索比较精准一些！

当然，magento的搜索设置也要设置好，太模糊的搜索会造成搜索的不精准。

下面是代码，覆盖文件template/catalogsearch/form.mini.phtml文件即可~！！！！

<?php

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

if(is_object(Mage::registry('current_category'))){

$current_category_path=Mage::registry('current_category')->getPathIds();

}else{

$current_category_path = array();

}

$category->load(Mage::app()->getStore()->getRootCategoryId());

$children_string = $category->getChildren();

$children = explode(',',$children_string);

$extra_options='';

foreach($children as $c){

$selected = (in_array($c, $current_category_path))?'SELECTED':'';

$extra_options.= '<option value="' . $c . '" ' . $selected . '>' . $category->load($c)->getName() . '</option>' . "\n";

}

?>

<form id="search_mini_form" action="<?php echo $this->helper('catalogSearch')->getResultUrl() ?>" method="get">

<fieldset>

<legend><?php echo $this->__('Search Site') ?></legend>

<div class="mini-search">

<input id="search" type="text" class="input-text" name="<?php echo $this->helper('catalogSearch')->getQueryParamName() ?>" value="<?php echo $this->helper('catalogSearch')->getEscapedQueryText() ?>" />

<?= $extra_options ?>
