我不知道代码哪里错了，就是不显示，不显示内容，只出现了个输入的proname值，求大神指点

Question

<?php

$link=@mysql_connect("localhost","root","root");

mysql_select_db("pro_info",$link) or die("不能选择数据库，".mysql_error());

$cname=$_POST["proname"];

echo $cname;//这句话可以显示

$where="";

$where="where name like '%$cname%'";

$sql="select *from product $where";

$query=mysql_query($sql) or die(mysql_error());

while($row=mysql_fetch_array($query))

{

echo $row['id'].$row[1].$row[2]."<br>";
