Question

我已經使用jquery來驗證我的表單數據。由於波紋管所示：

<form method="post" id="register-form" novalidate> 
<table width='100%> 
<tr class="dark"> 
<td> <strong>Event Date:</strong> </td> 
<td> <input type="date" name="event_date" id="event_date"> </td> 
</tr> 

<tr class="light"> 
<td> <strong> Description </strong> </td> 
<td> <input type="text" name="event_desc" id="event_desc"/> </td> 
</tr> 

<tr class="dark"> 
<td> <strong> Year </strong> </td> 
<td> <input type="text" name="year" id="year"/> </td> 
</tr> 

</table> 

<input type='submit' name='add' value='Save Event'> 
</form> 


<link href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.no-icons.min.css" rel="stylesheet"> 
<script src="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/js/bootstrap.min.js"></script> 

<link href="runnable.css" rel="stylesheet" /> 
<!-- Load jQuery and the validate plugin --> 
<script src="//code.jquery.com/jquery-1.9.1.js"></script> 
<script src="//ajax.aspnetcdn.com/ajax/jquery.validate/1.9/jquery.validate.min.js"></script> 

<!-- jQuery Form Validation code --> 
    <script> 

    // When the browser is ready... 
    $(function() { 

    // Setup form validation on the #register-form element 
    $("#register-form").validate({ 

     // Specify the validation rules 
     rules: { 
      event_date: "required", 
      event_desc: "required", 
      event_date: { 
       required: true, 
      }, 

     }, 

     // Specify the validation error messages 
     messages: { 
      event_date: "Please select a date", 
      event_desc: "Please enter event description", 
     }, 

     submitHandler: function(form) { 
      form.submit(); 
     } 
    }); 

    }); 

    </script> 

現在我的問題是，當我在哪裏可以使用插入查詢驗證結束在我的表中插入表單數據。我在說這個查詢：

<?php 
if(isset ($_POST['add'])) 
{ 
    mysql_query("INSERT into events (event_date, event_desc, year) 
        VALUES('".$_POST['event_date']."', 
          '".$_POST['event_desc']."', 
          '".$_POST['year']."') "); 

     echo "<script> alert('1 Record inserted!') </script>"; 
} 

那麼有人可以幫我怎麼做嗎？

請將您的查詢置於if if (isset($_POST['add'])){}條件以檢查發佈數據。

if(isset($_POST['add'])){ 
//... some code 

mysql_query("INSERT into events (event_date, event_desc, year) 
       VALUES('".$_POST['event_date']."', 
         '".$_POST['event_desc']."', 
         '".$_POST['year']."') "); 
//... some code 
}

<?php 
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password'); 
if (!$link) { 
    die('Could not connect: ' . mysql_error()); 
} 
mysql_select_db('YOUR_DB', $link); 
$result = mysql_query("set names 'utf8'"); 
$result = mysql_query("INSERT into events (event_date, event_desc, year) 
       VALUES('".$_POST['event_date']."', 
         '".$_POST['event_desc']."', 
         '".$_POST['year']."') ")OR die(mysql_error());; 
mysql_close($link); 
?>
