Question

怎么使用smarty连接数据库，和输出

我在php页面这样写的代码：
$query = "SELECT * FROM member where uid=$uid";

$result = mysql_query($query) or die("Query failed : " . mysql_error());

while($row = mysql_fetch_array($result))
{
echo $row['xingming'] . "<br/>";
} ;
这段代码可以换成smarty形式的吗

Answer 1

要将型启陆php代码写成函数并且保存成function.xingmings.php放在plugins目录里
<?php
function smarty_function_xingmings($params,&$smarty){

$uid = $params['uid']; //旁空取参数 uid

$query = "SELECT * FROM member where uid=$uid";

$result = mysql_query($query) or die("Query failed : " . mysql_error());
$xingmingArr=array();
while($row = mysql_fetch_array($result))
{
$xingmingArr[] = $row['xingming'];
}

//将数组返回给模板
$smarty->assign($thexingmings,$xingmingArr);
}

?>

模板里的调用卜顷代码
{xingmings val="thexingmings" uid="26"}
{section name=i loop=$thexingmings}
姓名列表：{$thexingmings[i].xingming}<br>
{/section}
