網站程式設計-PHP
==========

一、流程

```
<pre class="brush:as3;">

#列表
  default:
    $op="op_list";
    op_list();
  break;
```

二、函數

```
<pre class="brush:as3;">

########################################
# 列表
########################################
function op_list()
{
  global $mysqli,$smarty;

#取得所有記錄
  $sql = "select *
          from `show_kind`
          where `kind`='nav_home'
          order by `sort` ";
  $result = $mysqli->query($sql) or die(printf("Error: %s <br>".$sql, $mysqli->sqlstate));

$DBV=array();
  while($row = $result->fetch_assoc())
  {
    #過濾撈出資料
    $row['sn'] = intval($row['sn']);
    //http://www.w3school.com.cn/php/func_string_htmlspecialchars.asp
    $row['title'] = htmlspecialchars($row['title'], ENT_QUOTES); // 轉換雙引號和單引號
    $row['url'] = htmlspecialchars($row['url'], ENT_QUOTES); // 轉換雙引號和單引號
    $row['sort'] = intval($row['sort']);
    $row['enable'] = $row['enable'] ? "是":"<span style='color:red;'>否</span>";
    $row['target'] = $row['target'] ? "是":"<span style='color:red;'>否</span>";

$DBV[]= $row;
  }

$smarty->assign("DBV", $DBV);
  return;
}
```

三、樣板

```
<pre class="brush:as3;">

{* 選單管理 列表 *}
    {if $WEB.file_name == "nav_m.php" and $op == "op_list"}
      <div class="container" style="margin-top:20px;">
        <table class="table ">
          <thead>
            <tr>
              <th>標題</th>
              <th>網址</th>
              <th>外連狀態</th>
              <th>啟用狀態</th>
              <th>
                <button onclick="window.location.href='?op=op_form'" type="button" class="btn btn-primary">新增</button>
              </th>
            </tr>
          </thead>
          <tbody>
            {foreach from=$DBV item=row}
              <tr>
                <th>{$row.title}</th>
                <th>{$row.url}</th>
                <th>{$row.target}</th>
                <th>{$row.enable}</th>
                <th>
                  <button onclick="window.location.href='?op=op_show&sn={$row.sn}'" type="button" class="btn btn-warning">瀏覽</button>
                  <button onclick="window.location.href='?op=op_form&sn={$row.sn}'" type="button" class="btn btn-success">編輯</button>
                  <button onclick="javascript:op_delete_js({$row.sn});" type="button" class="btn btn-danger">刪除</button>
                </th>
              </tr>
            {/foreach}
          </tbody>
        </table>
      </div>

{/if}
