網站程式設計-PHP
==========

1. function.php 加上 ```
  <pre class="brush:as3;">
  
  defined('WEB_PATH') || die("WEB_PATH root path not defined");
  ```
2. 程式的流程，都是以<span style="color:#FF0000;">列表</span>為開始，故有需要將列表的網址存至 <span style="color:#FF0000;">$\_SESSION</span> ,讓程式可以順利回到<span style="color:#FF0000;">列表</span>。  
   function.php ```
  <pre class="brush:as3;">
  
  ###############################################################################
  #  取得目前網址
  ###############################################################################
  if(!function_exists("getCurrentUrl")){
  function getCurrentUrl(){
    global $_SERVER;
    $protocol = strpos(strtolower($_SERVER['SERVER_PROTOCOL']),'https')=== FALSE ? 'http' : 'https';
    $host     = $_SERVER['HTTP_HOST'];
    $script   = $_SERVER['SCRIPT_NAME'];
    $params   = $_SERVER['QUERY_STRING']?'?' . $_SERVER['QUERY_STRING']:"";
  
    $currentUrl = $protocol . '://' . $host . $script .  $params;
    return $currentUrl;;
  }
  }
  ```
  
   列表流程 ```
  <pre class="brush:as3;">
  
    //預設動作
    default:
    # ---- 目前網址 ----
    $_SESSION['CurrentUrl']=getCurrentUrl();
    $op="op_list";
    op_list();
    break;
  ```
  
   當程式有需要回到列表時，只要轉向至 <span style="color:#FF0000;">$\_SESSION\['CurrentUrl'\]</span> 即可  
   在顯示單筆的樣板 ```
  <pre class="brush:as3;">
      
          <div style="margin:10px 0;">
            <button onclick="window.location.href='{$smarty.session.CurrentUrl}'" type="button" class="btn btn-warning">返回</button>
          </div>
  ```
3. 在單筆顯示增加一個編輯按鈕 ```
  <pre class="brush:as3;">
            
            <button onclick="window.location.href='?op=op_form&sn={$DBV.sn}'" type="button" class="btn btn-success">編輯</button>
  ```
4. 刪除完轉向列表的$\_SESSION\['CurrentUrl'\]
5. 列表樣板修改 ```
  <pre class="brush:as3;">
  
  
      {* 選單管理 列表 *}
      {if $WEB.file_name == "nav_m.php" and $op == "op_list"}
        {literal}
          <link rel="stylesheet" href="../class/sweet-alert/sweet-alert.css" type="text/css" />
          <script src="../class/sweet-alert/sweet-alert.js" type="text/javascript"></script>
          <script type="text/javascript">
            function op_delete_js(sn){
              swal({
                title: '確定要刪除此資料？',
                text: '相關資料通通都將會被移除！',
                type: 'warning',
                showCancelButton: 1,
                confirmButtonColor: '#DD6B55',
                confirmButtonText: '確定刪除！',
                closeOnConfirm: false ,
                allowOutsideClick: true
              },
              function(){
                location.href='nav_m.php?op=op_delete&sn=' + sn;
              });
            }
          </script>
        {/literal}
        <div class="container" style="margin-top:20px;">
          <h2 class="text-center">選單管理</h2>
          <table class="table table-bordered table-hover list-table">

              </tr>
            </thead>
            <tbody>
              {foreach from=$DBV item=row}
                <tr>
