老師您好:
關於14.4章中落實權限機制，若$_SESSION['user_name']不存在則轉向index.php，但$op在index.html中被判斷
{if $op=="goods_form"}
{include file="goods_form.html"}
{elseif $op=="goods_display"}
{include ile='goods_display.html'}
{elseif $op=="user_form"}
{include file='user_form.html'}
{elseif $op=="display_user"}
{include file='display_user.html'}
{else}
{include file='goods_list.html'}
{/if}
所以在index.php?op=goods_form就能帶出goods_form，那不就不用登入就能編
輯了，有測試過喔!
