PHP SMARTY 樣板引擎
===============

1. 類別下拉選單，我們屆時會將類別儲存在「ugm\_p\_kind」資料表，當我們需要選單時，再從資料表撈出  
   不過這裡，我們先用陣列來代替  
   程式 - 預設值 ```
  <pre class="brush:as3;">
  
    $row['kind'] = isset($row['kind']) ? $row['kind']: "";  
    $row['kind_options'] = get_kind_options($row['kind']);
  ```
  
   程式 - 函數(取得選項，傳入預設值，selected 代表選擇) ```
  <pre class="brush:as3;">
  
  function get_kind_options($default=""){
    global $db;
    $kind_options = array(
      "1"=>"類別1",
      "2"=>"類別2",
      "3"=>"類別3",
      "4"=>"類別4",
      "5"=>"類別5"
    );  
  
    $options = "";
    foreach($kind_options as $key=> $option){
      $selected = ($default == $key) ? " selected":"";
      $options .="<option value='{$key}'{$selected}>{$option}</option>";
    }
    return $options;
  }
  ```
  
   樣板 ```
  <pre class="brush:as3;">
  
            <div class="col-sm-3">
              <div class="form-group">
                <label for="kind">類別</label>
                <select name="kind" class="form-control" size="1">
                  <{$row.kind_options}>
                </select>
              </div>
            </div>
  ```
2. 商品價格  
   樣板 ```
  <pre class="brush:as3;">
  
            <div class="col-sm-3">
              <div class="form-group">
                <label for="price">商品價格</label>
                <input type="text" class="form-control" id="price" name="price" value="<{$row.price}>">
              </div>            
            </div>
  ```
3. 商品數量  
   樣板 ```
  <pre class="brush:as3;">
  
            <div class="col-sm-3">
              <div class="form-group">
                <label for="amount">商品數量</label>
                <input type="text" class="form-control" id="amount" name="amount" value="<{$row.amount}>">
              </div>            
            </div>
  ```
