MYSQL与Smarty的应用
在三十讲遇到这样一个问题就是运行代码时出现错误 Fatal error: Call to undefined method mysql::fetch_array() in D:\WWW\news\index.php on line 12
，我把mysql::fetch_array() 改成mysql::fetch_row() 又出现Fatal error: Call to undefined method mysql::fetch_row() in D:\WWW\news\index.php on line 12
,以至我读不到{$row[1]}，具体的代码如下，
//.......smarty_inc.php
<?php
include_once("Smarty/Smarty.class.php"); //包含smarty类文件
$smarty = new Smarty(); //建立smarty实例对象$smarty
$smarty->config_dir="Smarty/Config_File.class.php"; // 目录变量
$smarty->template_dir = "./templates"; //设置模板目录
$smarty->compile_dir = "./templates_c"; //设置编译目录
$smarty->cache_dir = "./caches/"; //缓存目录
$smarty->caching = true; //开启缓存,为flase的时侯缓存无效
$smarty->cache_lifetime = 600; //缓存时间
//----------------------------------------------------
//左右边界符，默认为{}，但实际应用当中容易与JavaScript相冲突
//----------------------------------------------------
$smarty->left_delimiter = "{";
$smarty->right_delimiter = "}";
?>
//......mysql_class.php
<?php

我用的like模糊查询，比如mysql的name中有“csdn论坛系统”这几个字，如何在 <input>中查询“csdn 系统”也能出来这个“csdn论坛系统”，我现在是查“csdn”或者“系统”都可以。谢谢各位了！不知道我这么表达 ......
