11-2 列出單一活動

一、製作函數

1. 讀出單一活動的流程已經有了，所以，直接完成函數show_action($action_id)

   //列出指定活動
   function show_action($action_id)
   {
       global $db, $smarty;
   
       $sql    = "SELECT * FROM `actions` where `action_id` ='{$action_id}'";
       $result = $db->query($sql);
       if (!$result) {
           throw new Exception($db->error);
       }
       $action = $result->fetch_assoc();
       $smarty->assign('action', $action);
   }

二、修改主樣板

1. 編輯 templates\index.tpl

   {if $op=="regist"}
     {include file='regist_form.tpl'} 
   {elseif $op=="list_action"}
     {include file='list_action.tpl'}
   {elseif $op=='show_action'}
     {include file='show_action.tpl'}
   {else}
     {$content}
   {/if}

三、新增專屬樣板

1. 新增 templates\show_action.tpl

   <h2>{$action.title}</h2>
   
   <div class="panel panel-default">
     <div class="panel-heading">活動日期：{$action.action_date}</div>
     <div class="panel-body">
       {$action.content}
     </div>
     <div class="panel-footer">報名截止日：{$action.end_date}</div>
   </div>
