Ajax to PHP Undefined Index Passed as data:
Question
how are you doing? I can't figure out why I'm getting an Undefined Index error in my code. I've been through most of the postings on this site, and tried adding the dataType, the parentheses, using the serialize method, etc.

$(document).ready(function () {

if (fname == "") {
$('#fname').css("backgroundColor", "#f7e7e1");
}
else if (lname == "") {
$('#lname').css("backgroundColor", "#f7e7e1");
}
else {
$.ajax({
url: 'register.php',
method: 'POST',
data: { data: $('#registerForm').serialize() },
success: function (response) {
console.log("Hello World!!!");
},
dataType: 'text'
});

});
});
</script>
</body>
And here is the PHP document below. When Passing the data, and monitoring it via the browser's debugging tool, it shows register: with no data.
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "museum";
if (isset($_POST['register'])) {
$conn = new mysqli($servername, $username, $password, $dbname);
if($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$fname = $_POST['fname'];
$mi = $_POST['mi'];
$lname = $_POST['lname'];
$address = $_POST['address'];
$address2 = $_POST['address2'];
$city = $_POST['city'];
$state = $_POST['state'];
$zipcode = $_POST['zipcode'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$sql = "INSERT INTO guest (fname, mi, lname, address1, address2, city, state, zipcode, email, phone) VALUES ('$fname', '$mi', '$lname', '$address', '$address2', '$city', '$state', '$zipcode', '$email', '$phone')";
if($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
}
?>

An easier way would be to add an ID to your form and add the name="" attribute to your input fields. Then, when you're going to post them with Ajax, all you need to do is: data: $('#the-form-id').serialize(). No need to define all the fields in JS. – Magnus Eriksson 6 hours ago
This worked, had to take out the variable initializations, and add the name attribute to each of the inputs. Then the program worked as expected.
