$shop_qu="select * from phone where p_id=$id";
mysql_select_db('htc',$conn);
$shop_re1=mysql_query($shop_qu);
[color=#FF0000]while ($shop_re2=mysql_fetch_row($shop_re1)){[/color]
foreach ($shop_re2 as $va){
报错
Warning: mysql_fetch_row() expects parameter 1 to be resource, boolean given in
我确定连接没问题,以前调试的时候就是这样用的,
但是后来修改功能的时候重写了语句 然后就报错了,
我又在数据库里试了试赋值后的语句,有结果,但就是php里调用不了
------解决方案--------------------
$shop_re1 = mysql_query($shop_qu) or die("Invalid query: " . mysql_error());
试下这个
------解决方案--------------------$id有值吗
$shop_qu="select * from phone where p_id=$id";
echo $shop_qu; //把这个$shop_qu打印出来
