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~！！！！

 

1. <?php
2. $category = Mage:: getModel ( 'catalog/category' );
3. if ( is_object (Mage:: registry ( 'current_category' ) ) ) {
4.     $current_category_path=Mage:: registry ( 'current_category' )-> getPathIds ( );
5. } else {
6.     $current_category_path = array ( );
7. }
8. $category-> load (Mage:: app ( )-> getStore ( )-> getRootCategoryId ( ) );
9. $children_string = $category-> getChildren ( );
10. $children = explode ( ',', $children_string );
11. $extra_options= '';
12. foreach ( $children as $c ) {
13.     $selected = ( in_array ( $c, $current_category_path ) )? 'SELECTED': '';
14.     $extra_options.= '<option value="' . $c . '" ' . $selected . '>' . $category-> load ( $c )-> getName ( ) . '</option>' . "\n";
15. }
16. ?>
17. <form id= "search_mini_form" action= "<?php echo $this->helper('catalogSearch')->getResultUrl() ?>" method= "get">
18.     <fieldset>
