本文主要作用是将一个子类对应多个父类,并指定条跳转url的功能。ecshop是一款在线购物网站,感兴趣的可以下载源码看看。我们看看具体是怎么修改的。 1、数据库表“表前缀_category”添加如下字段 alter TABLE `ga_category` add `assign_child` varchar(255) default NULL; alter TABLE `ga_category` add `jump_url` varchar(255) default NULL; 2、includes/lib_goods.php get_categories_tree、get_child_tree函数中的 $cat_arr[$row[‘cat_id’]][‘url’] = build_uri(‘category’, array(‘cid’ => $row[‘cat_id’]), $row[‘cat_name’]); 改为 if(isset($row[‘jump_url’]) != NULL && trim($row[‘jump_url’]) != ”){ $cat_arr[$row[‘cat_id’]][‘url’] = $row[‘jump_url’]; }else{ $cat_arr[$row[‘cat_id’]][‘url’] = build_uri(‘category’, array(‘cid’ => $row[‘cat_id’]), $row[‘cat_name’]); } 将 $three_arr[$row[‘cat_id’]][‘cat_id’] = get_child_tree($row[‘cat_id’]); 改为 if(isset($row[‘assign_child’]) != NULL && trim($row[‘assign_child’]) != ”){ $three_arr[$row[‘cat_id’]][‘cat_id’] = get_assign_child_tree($row[‘assign_child’]); }else{ $three_arr[$row[‘cat_id’]][‘cat_id’] = get_child_tree($row[‘cat_id’]); } 将将获取子类的sql $sql = ‘SELECT cat_id,cat_name ,parent_id,is_show ‘ . ‘FROM ‘ . $GLOBALS[‘ecs’]->table(‘category’) . “WHERE parent_id = ‘$parent_id’ AND is_show = 1 ORDER BY sort_order ASC, cat_id ASC”; 改为(添加assign_child, jump_url两个字段用于查询用) $sql = ‘SELECT cat_id,cat_name ,parent_id,is_show, template_file, assign_child, jump_url ‘ . ‘FROM ‘ . $GLOBALS[‘ecs’]->table(‘category’) . “WHERE parent_id = ‘$parent_id’ AND is_show = 1 ORDER BY sort_order ASC, cat_id ASC”; 并添加函数 function get_assign_child_tree($tree_id = ”) { $three_arr = array(); if($tree_id == ”) return $three_arr; $child_sql = ‘SELECT cat_id, cat_name, parent_id, is_show, assign_child, jump_url ‘ . ‘FROM ‘ . $GLOBALS[‘ecs’]->table(‘category’) . “WHERE cat_id in( $tree_id ) AND is_show = 1 ORDER BY sort_order ASC, cat_id ASC”; $res = $GLOBALS[‘db’]->getAll($child_sql); foreach ($res AS $row) { if ($row[‘is_show’]) $three_arr[$row[‘cat_id’]][‘id’] = $row[‘cat_id’]; $three_arr[$row[‘cat_id’]][‘name’] = $row[‘cat_name’]; if(isset($row[‘jump_url’]) != NULL && trim($row[‘jump_url’]) != ”){ $three_arr[$row[‘cat_id’]][‘url’] = $row[‘jump_url’]; }else{ $three_arr[$row[‘cat_id’]][‘url’] = build_uri(‘category’, array(‘cid’ => $row[‘cat_id’]), $row[‘cat_name’]); } if (isset($row[‘cat_id’]) != NULL) { if(isset($row[‘assign_child’]) != NULL && trim($row[‘assign_child’]) != ”){ $three_arr[$row[‘cat_id’]][‘cat_id’] = get_assign_child_tree($row[‘assign_child’]); }else{ $three_arr[$row[‘cat_id’]][‘cat_id’] = get_child_tree($row[‘cat_id’]); } } } return $three_arr; } 3、admin/category.php中作如下修改 在($_REQUEST[‘act’] == ‘insert’)、if ($_REQUEST[‘act’] == ‘update’)的条件中的 $cat[‘grade’] = !empty($_POST[‘grade’]) ? intval($_POST[‘grade’]) : 0; $cat[‘filter_attr’] = !empty($_POST[‘filter_attr’]) ? implode(‘,’, array_unique(array_diff($_POST[‘filter_attr’],array(0)))) : 0; 后面添加 $cat[‘jump_url’] = !empty($_POST[‘jump_url’]) ? trim($_POST[‘jump_url’]) : ”; $cat[‘assign_child’] = !empty($_POST[‘assign_child’]) ? trim($_POST[‘assign_child’]) : ”; 4、在admin/templates/category_info.htm的 <tr id=”assign_child”> <td class=”label”>{$lang.assign_child}:</td> <td> <input type=”text” name=’assign_child’ value='{$cat_info.assign_child}’ size=”32″ /> </td> </tr> 中添加 <tr id=”jump_url”> <td class=”label”>{$lang.jump_url}:</td> <td> <input type=”text” name=’jump_url’ value='{$cat_info.jump_url}’ size=”32″ /> </td> </tr> 5、languages/zh-cn/admin/category.php中添加如下语言描述 $_LANG[‘jump_url’]=’跳转url(指定跳转至的url)’; $_LANG[‘assign_child’]=’指定子类(将其id填写在输入框中即可,多个是用应为的“,”号隔开)’;
