怎么用PHPLIB做二层循环？(附我的代码,有错误)

Question

$tpl->set_block("index","Tcity","Tcitydata");//二层循环的两个block
$tpl->set_block("index","Ecity","Ecitydata");记得有一个大小问题的。
试着反一下看看。$tpl->set_block("index","Ecity","Ecitydata");
$tpl->set_block("index","Tcity","Tcitydata");//二层循环的两个block

Answer 1

$tpl->set_block("index","Tcity","Tcitydata");//二层循环的两个block
$tpl->set_block("index","Ecity","Ecitydata");
能这样放吗？

Answer 3

1、
$tpl->set_block("index","Tcity","Tcitydata");//二层循环的两个block
$tpl->set_block("index","Ecity","Ecitydata");
改做
$tpl->set_block("index","Tcity","Tcitydata");//二层循环的两个block
$tpl->set_block("Tcity","Ecity","Ecitydata");2、
//$tpl->set_var("Tcitydata");//清除上一次二层循环的结果
改做
$tpl->set_var("Ecitydata");//清除上一次二层循环的结果3、
把$tpl->parse("Tcitydata","Tcity",true);
移到二层循环之后
