PHP form not submitting correctly - php

Question

I have a form that displays user data based on a query. The form is meant to allow users to update their user account information. i.e., First name, Last name, Email address, etc.
account.php - form
<form class="form-horizontal" role="form" method="post" action="">
<div class="form-group">
<label class="col-lg-3 control-label">First name:</label>
<div class="col-lg-8">
<input class="form-control" name="fName" type="text" placeholder="<?php echo $fName ?>">
</div>
</div>
<div class="form-group">
<label class="col-lg-3 control-label">Last name:</label>
<div class="col-lg-8">
<input class="form-control" name="lName" type="text" placeholder="<?php echo $lName ?>">
</div>
</div>
<div class="form-group">
<label class="col-lg-3 control-label">Email:</label>
<div class="col-lg-8">
<input class="form-control" name="emailAddress" type="text" placeholder="<?php echo $emailAddress ?>">
</div>
</div>
<div class="form-group">
<label class="col-md-3 control-label">Username:</label>
<div class="col-md-8">
<input class="form-control" name="username" type="text" placeholder="<?php echo $username ?>">
</div>
</div>
<div class="form-group">
<label class="col-md-3 control-label">Password:</label>
<div class="col-md-8">
<input class="form-control" name="password" type="password">
</div>
</div>
<div class="form-group">
<label class="col-md-3 control-label">Confirm password:</label>
<div class="col-md-8">
<input class="form-control" name="confirmPassword" type="password">
</div>
</div>
<div class="form-group">
<label class="col-md-3 control-label"></label>
<div class="col-md-8">
<input class="btn btn-primary" value="Update" name="updateaccount" type="button">
<span></span>
<input class="btn btn-default" value="Cancel" type="reset">
</div>
</div>
</form>
updateaccount.php
<?php
$msg = "";
if(isset($_POST["updateaccount"]))
{
$fName = $_POST["fName"];
$lName = $_POST["lName"];
$username = $_POST["username"];
$emailAddress = $_POST["emailAddress"];
$password = $_POST["password"];
$fName = mysqli_real_escape_string($db, $fName);
$lName = mysqli_real_escape_string($db, $lName);
$username = mysqli_real_escape_string($db, $username);
$emailAddress = mysqli_real_escape_string($db, $emailAddress);
$password = mysqli_real_escape_string($db, $password);
$password = md5($password);
$sql="SELECT emailAddress FROM users WHERE emailAddress='$emailAddress'";
$result=mysqli_query($db,$sql);
$row=mysqli_fetch_array($result,MYSQLI_ASSOC);
if(mysqli_num_rows($result) == 1)
{
$msg = "Sorry...This email already exists";
}
else
{
$query = mysqli_query($db, "INSERT INTO users (fName, lName, username, emailAddress, password)VALUES ('$fName', '$lName', '$username', '$emailAddress, '$password')");
if($query)
{
$msg = "Your account has been updated";
}
}
}
?>
The above code is called on the account.php page:
include ("getuseraccount.php");
Did I miss something?

Answer 1

You are using input type button instead of submit for the Update button. Use 'submit' type instead of 'button' type.
<input class="btn btn-primary" value="Update" name="updateaccount" type="button">
try
<input class="btn btn-primary" value="Update" name="updateaccount" type="submit">

Answer 2

Unless you're using Ajax to submit the form (which you made no mention of, you need to add the file that you are submitting the form information to.
<form class="form-horizontal" role="form" method="post" action="updateaccount.php">
