好吧，一个接一个地解决一些问题，现在我试图让我的下拉菜单数据提交。我不知道从哪里开始。
这是我的表格..这里有什么问题吗？：
<form action="form.php" method="POST">
<div class="row">
<div class="large-4 columns">
<span id="spryfirstname">
<input name="firstname" type="text" placeholder="First Name"/>
<span class="textfieldRequiredMsg">A value is required.</span></span></div>
<div class="large-4 columns">
<span id="sprylastname">
<input name="lastname" type="text" placeholder="Last Name"/>
<span class="textfieldRequiredMsg">A value is required.</span></span></div>
<div class="large-4 columns">
<div class="row collapse">
<div class="small-9 columns"><span id="spryemail">
<input name="email" type="text" placeholder="[email protected]"/>
<span class="textfieldRequiredMsg">A value is required.</span></span></div>
</div>
</div>
</div>
<div class="row">
<div class="large-12 columns">
<label>Check all Products that you're interested in</label>
<input name="products[]" type="checkbox" value="all">

<hr>
</div>
</div>
<div class="row">
<div class="large-12 columns">
<label>How often would you like to have product updates? <select>
<option value="daily" name="Updates">Daily</option>
<option value="weekly" name="Updates">Weekly</option>
<option value="monthly" name="Updates">Monthly</option>
</select>
</label>
</div>
</div>
<div class="row">
<div class="large-12 columns">
<label>Tell us a little about yourself <textarea placeholder="Type here">
</textarea>
</label>
</div>
</div>
<div class="row">
<input class="button small large-3" type="submit" name="submit" />
</div>
</form>
这是我与数据库/ php的连接：
<?php
if(isset($_POST['submit'])){
$con = mysqli_connect("localhost","dxh6110","tcqfoz7","dxh6110")
or die("Error " . mysqli_error($con));
$first = stripslashes($_POST['firstname']);
$last = stripslashes($_POST['lastname']);
$email = stripslashes($_POST['email']);
$checkbox = stripslashes($_POST['products']);
$first = mysqli_real_escape_string($con,$_POST['firstname']);
$last = mysqli_real_escape_string($con,$_POST['lastname']);
$email = mysqli_real_escape_string($con,$_POST['email']);
$checkbox = mysqli_real_escape_string($con,$_POST['products']);
$checkbox = implode(',', $_POST['products']);
$sql = "INSERT INTO Register (Firstname,Lastname,Email,Product)
VALUES('".$firstname."','".$lastname."','".$email."','".$checkbox."')";
}
mysqli_query($con,$sql);
mysqli_close($con);
?>
好吧，部分问题是，每次您访问该页面时，它将添加另一行。无论是否提交，都请添加以下内容：
if(isset($_POST['Submit'])){
}只需将所有php包裹起来，然后转到^。^，所以继续删除它得到的所有空白行，然后重试。这样，您可以对其进行更好的调试。
因此，这说明了您遇到的空白行问题。;）3个中没有什么？
