一个小小的传值问题，应该很简单。

Question

=<?=trim($_POST["idno"])?>&hc_id=<?=trim($_POST["hc_id"])?>"> <?}不知道这样可以不？

Answer 1

Only trim  not echo

Answer 2

if(strlen($_POST["hc_id"])==13){?> <meta http-equiv="refresh" content="0;URL=/cs/login.jsp?idno=<?php echo trim($_POST["idno"])?>&hc_id=<?php echo trim($_POST["hc_id"])?>"> <?}

Answer 3

if(strlen($_POST["hc_id"])==13){?> <meta http-equiv="refresh" content="0;URL=/cs/login.jsp?idno=<?php=trim($_POST["idno"])?>&hc_id=<?php=trim($_POST["hc_id"])?>"> <?}
这样也是可以的
