未定义指数PHP的错误POST方法

Question

我的HTML从代码：

<form action="#" class="Test" method="post"> 
<label>Please Choose Your Place :</label> 
<input type="text" required list="Places" autocomplete="on"/> 
<datalist id="Places"> 
<option value="EG"></option> 
<option value="USA"></option> 
<option value="Test"></option> 
<option value="Test"></option> 
<option value="Test"></option> 
</datalist> 
<label>Where are you go? :</label> 
<input type="text" required list="Place" autocomplete="on"/> 
<datalist id="Place"> 
<option value="EG"></option> 
<option value="USA"></option> 
<option value="Test"></option> 
<option value="Test"></option> 
<option value="Test"></option> 
</datalist> 
<input name="OK" type="submit"/> 

我的PHP代码：

if(isset($_POST['OK'])) 
    { 
     $Places=$_POST['Places']; 
     $Place=$_POST['Place']; 
     $sql="SELECT * FROM 'test' WHERE Places='$Places' and Place='$Place' and describt='$describt'"; 
     $query=mysql_query($sql); 

    while (mysql_fetch_row($query)) 
    { 

注意：未定义指数：地方G：\ XAMPP \ htdocs中\ S \的index.php上线41

说明：未定义指数：将在G：\ XAMPP \ htdocs中\ S \上线的index.php 42

注意：未定义变量：describt在G：\ XAMPP \ htdocs中\ S \的index.php上线43

警告：mysql_fetch_row（）能够预计参数1是资源，布尔G中给出：\ XAMPP \ htdocs中\上线S \的index.php 46

请帮我

，你必须使用name属性没有ID

<form action="#" class="Test" method="post"> 
<label>Please Choose Your Place :</label> 
<input type="text" required list="Places" autocomplete="on"/> 
<datalist name="Places"> 
<option value="EG"></option> 
<option value="USA"></option> 
<option value="Test"></option> 
<option value="Test"></option> 
<option value="Test"></option> 
</datalist> 
<label>Where are you go? :</label> 
<input type="text" required list="Place" autocomplete="on"/> 
<datalist name="Place"> 
<option value="EG"></option> 
<option value="USA"></option> 
<option value="Test"></option> 
<option value="Test"></option> 
<option value="Test"></option> 
</datalist> 
<input name="OK" type="submit"/> 

Howeve如果你需要的ID，然后同时使用id和name属性。
