What is wrong with my Register function? - php

Question

Problem & Explanation
Hello I have just coded a function that first does checking if account exists in database with that name, and then if email exists in database with that entered email.
If not, return true + insert data.
But in this case, nothing happens on submit, it just shows the form, but doesn't inserts the data..
What is wrong with it?
function createAccount($name, $password, $email)
{
global $pdo;
$check_in = $pdo->prepare("SELECT * FROM users WHERE user_name = :username LIMIT 1");
$check_in->execute( array(':username' => $name) );
if (!$check_in->rowCount())
{
$check_in = email_exists($email);
if ($check_in === false)
{
$insert_in = $pdo->prepare
("
INSERT INTO
users
(user_name, user_password, user_email)
VALUES
(:name, :password, :email)
");
$insert_in->execute( array
(
':name' => $name,
':password' => $password,
':email' => $email
));
return true;
}
else
{
return 'exists';
}
}
else
{
return 'user_in_use';
}
}
function email_exists($email)
{
global $pdo;
$check = $pdo->prepare("SELECT * FROM users WHERE user_email = :email LIMIT 1");
$check->execute( array(':email' => $email) );
if ($check->rowCount())
{
return true;
}
else
{
return false;
}
}
This is how I make up the register:
# Creating shortcuts
if (isset($_POST['username']) && isset($_POST['password']) && isset($_POST['email']))
{
$name = $_POST['username'];
$password = $_POST['password'];
$email = $_POST['email'];
}
# Creating errors array
$errors = array();
if (isset($_POST['submit']))
{
$check_in = createAccount($name, $password, $email);
if ($check_in === true)
{
echo 'Created account sucessfully!';
}
else if ($check_in == 'already_in_use')
{
echo 'Could not create account because name already in use..';
}
else if($check_in == 'exists')
{
echo 'Email already in use..';
}
}
Question:
What is wrong with this code & how do I fix this? I have no errors at all.
It just won't insert any data to the Database.
Yes, the PDO connection & statements are right, because the login works perfectly.
Thanks a lot!
EDIT!
if ($check_in === true)
{
echo 'Created account sucessfully!';
}
else if ($check_in == 'already_in_use')
{
echo 'Could not create account because name already in use..';
}
else if($check_in == 'exists')
{
echo 'Email already in use..';
} else {
echo 'Error is there...';
}
It's echoing 'Error is there...' apon submit!

I just want to slap myself!.....
The problem was: The fields were set as INT, therefore we could not store anything but ints...
