JQuery Post to PHP Inserts data, but json response is null - php

Question

I'm building a simple sign up form with AngularJS and sending the data to a PHP page using JQuery's $.post(). When I send the data, it correctly gets inserted into the database. However, the returned json that I am logging is showing my data fields as null.
Console:
{"status":"success","email":null,"id":null,"sessionId":null}
Javascript:
$.post("admin/addUser.php", {
email: form.email,
password: form.password
}).done(function(data){
console.log(data);
});
PHP:
$email = mysql_real_escape_string($_POST["email"]);
$password = md5(mysql_real_escape_string($_POST["password"]));
$sessionId = md5(uniqid(microtime()) . $_SERVER['REMOTE_ADDR'] . $_SERVER['HTTP_USER_AGENT']);
//Add this user to the database
$sql = mysql_query("INSERT INTO users (email, password, sessionId) VALUES ('".$email."', '".$password."', '".$sessionId."')");
if ($sql){
//Now find the user we just added
$getUser = mysql_query("SELECT * FROM users WHERE email = '".$email."' AND sessionId = '".$sessionId."'");
if ($getUser){
$row = mysql_fetch_array($getUser);
$user = array(
'status' => 'success',
'email' => $row['email'],
'id' => $row['id'],
'sessionId' => $row['sessionId']
);
echo json_encode($user);
}else{
$user = array(
'error' => mysql_error()
);
echo json_encode($user);
}
}else{
$user = array(
'error' => mysql_error()
);
echo json_encode($user);
}

Answer 1

Are you sure that you have only one record in here
$getUser = mysql_query("SELECT * FROM users WHERE email = '".$email."' AND sessionId = '".$sessionId."'");
Try to dump $row and see the response. BTW I would suggest you to add limit
$getUser = mysql_query("SELECT * FROM users WHERE email = '".$email."' AND sessionId = '".$sessionId."' LIMIT 1");

Answer 2

Ok, I dug around and found the answer to this. It was a mistake on my end. I was only storing the password and sessionId as varchar(30). When I was generating the sessionId and checking it against the DB, it was being cut off when it was stored, since I was only allowing 30 chars. I update to 255 and works as expected :-P.
