==========

一、分析所需表單欄位：

<span style="color:#000080;">標題</span><span style="color:#FF0000;"> title </span><span style="color:#800080;">(text)</span><span style="color:#FF0000;">、</span><span style="color:#0000CD;">網址</span><span style="color:#FF0000;"> url </span><span style="color:#800080;">(text)</span><span style="color:#FF0000;">、</span><span style="color:#0000CD;">是否外連</span><span style="color:#FF0000;"> target </span><span style="color:#800080;">(radio)</span><span style="color:#FF0000;">、</span><span style="color:#0000CD;">是否啟用</span><span style="color:#FF0000;"> enable </span><span style="color:#800080;">(radio)</span><span style="color:#FF0000;">、</span><span style="color:#0000CD;">排序</span><span style="color:#FF0000;"> sort</span><span style="color:#800080;">(text) </span>  
 <span style="color:#FF0000;">分類 kind="nav\_home"</span>

二、流程控制：

收到 op\_form 進入表單(新增、編輯) => 送出一個 op\_insert、op\_update(寫入資料庫、更新資料庫)

三、函數：

op\_form($sn)

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

########################################
# 表單
########################################
function op_form($sn="")
{
  global $mysqli,$smarty;

#抓取預設值
  if($sn)
  {
    #編輯
    $DBV['op'] = "op_update";
    $DBV['form_title'] = "編輯選單";
  }else
  {
    #新增
    $DBV=array();

$DBV['op'] = "op_insert";
    $DBV['form_title'] = "新增選單";
  }

//預設值設定
  //標題 title (text)、網址 url (text)、是否外連 target (radio)、是否啟用 enable (radio)、排序 sort(text)

$DBV['sn']     = (isset($DBV['sn']))     ? $DBV['sn']     : "";
  $DBV['title']  = (isset($DBV['title']))  ? $DBV['title']  : "";
  $DBV['enable'] = (isset($DBV['enable'])) ? $DBV['enable'] : "1";
  $DBV['target'] = (isset($DBV['target'])) ? $DBV['target'] : "0";
  $DBV['url']    = (isset($DBV['url']))    ? $DBV['url']    : "";
  $DBV['sort']   = (isset($DBV['sort']))   ? $DBV['sort']   : "";

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

四、在樣板製作表單

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

{* nav_m.php and op_form *}
    {if $WEB.file_name == "nav_m.php" and $op == "op_form"}
      <div class="container" style="margin-top:20px;">
        <div class="panel panel-primary">
          <div class="panel-heading">
            <h3 class="panel-title">{$DBV.form_title}</h3>
          </div>
          <div class="panel-body">

</div>
                </div>
                <div class="col-md-2">
                  <div class="form-group">
                    <label style="display:block;">啟用狀態</label>

</div>
                </div>
                <div class="col-md-2">
                  <div class="form-group">
                    <label>排序</label>
                    <input type="text" class="form-control" id="sort"  name="sort"  value="{$DBV.sort}" placeholder="排序">
                  </div>
                </div>
              </div>

<input type="hidden" name="op" value="{$DBV.op}">
              <input type="hidden" name="sn" value="{$DBV.sn}">
              <button type="submit" class="btn btn-default">送出</button>
            </form>

</div>
        </div>
      </div>

{/if}
```
