我有一个＆＃34;注册＆＃34;在模态和脚本中形成如下：
$(function () {
$("#lala").on('submit', function (e) {
e.preventDefault();
$.ajax({
type: 'post',
url: 'signup.php',
data: $("#lala").serialize(),
success: function () {
alert('form was submitted');
}
});
});
});<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel"
aria-hidden="true">

我的＆＃34; signup.php＆＃34;看起来像这样：
<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "eam";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn){
die("Connection failed: " . mysqli_connect_error());
}
$email = $_POST["email"];
$pwd = $_POST['password'];
$honorific = $_POST['honorific'];
$fullname = $_POST['fullname'];
$persona = $_POST['persona'];
$sql = "SELECT MAX(id) AS maxid FROM registered";
$result = $conn->query($sql);
if ($result->num_rows == 0) {
$id = 1;
}
else{
$row = $result->fetch_assoc();
$id = $row['maxid']+1;
}
$sql = "INSERT INTO registered (id, email, password, honorific, fullname, persona)
VALUES ({$id}, {$email}, {$pwd}, {$honorific}, {$fullname}, {$persona})";
if (mysqli_query($conn, $sql)) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}
mysqli_close($conn);
?>
问题在于，无论我尝试过什么，表单变量都不会传递给signup.php。我检查过它们，是的，它们是空的。有什么办法可以帮助我找出原因吗？
