Cant create a user using Laravel framework - php

Question

I am using Laravel 4 and the following code suffers from a bug that i am not being able to find it :(
So i require your help.
One of the part of my code (that gives me the error) is shown here:
if($status == 'admin')
{
$role_id = 1;
}
else
{
$role_id = 2;
}
$check_role = DB::table('roles')->where('id', $role_id)->pluck('id');
if(($password == $repeat_password)&&($check_role != 0)&&($first_name != "")&&($last_name != ""))
{
$user = User::create(array('username' => $username, 'password' => Hash::make($password), 'first_name'=>$first_name, 'last_name' => $last_name, 'no_total_leaves' => $no_total_leaves, 'active' => $active, 'role_id' => $role_id));
return View::make('pages/manageUsers')->with('info', 'Success!');
}
else
{
return View::make('pages/manageUsers')->with('info','Failed!');
}
I want to make you sure that roles table exists and it hase two rows (id =1 is admin, and is=2 is user).
The following error is shown:
SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`leaves_db`.`users`, CONSTRAINT `users_role_id_foreign` FOREIGN KEY (`role_id`) REFERENCES `roles` (`id`)) (SQL: insert into `users` (`username`, `password`, `first_name`, `last_name`, `no_total_leaves`, `active`, `updated_at`, `created_at`) values (demo .demo, y$BuTWHRpfPl.OztGhTltjteqvGZZ6xcbzlAnCgwrZYRxRDxB.fuqHe, demo , demo, 0, 1, 2015-01-12 11:35:55, 2015-01-12 11:35:55))

Answer 1

As per above mentioned code, you are not inserting value of column role_id in table USERS.
Bare in mind that column role_id in table USERS is foreign key of column ID on table ROLES. So It should always be included in your every insert statement.
$user = User::create(array('username' => $username, 'password' => Hash::make($password), 'first_name'=>$first_name, 'last_name' => $last_name, 'no_total_leaves' => $no_total_leaves, 'active' => $active, 'role_id' => $role_id));

Answer 2

It seems the query that is running is not actually inserting the role_id. I cannot see it in the query that the error shows.

Answer 3

Thanks for your support. I needed to use this row instead:
DB::table('users')->insert(array('username' => $username, 'password' => Hash::make($password), 'first_name'=>$first_name, 'last_name' => $last_name, 'no_total_leaves' => $no_total_leaves, 'active' => $active, 'role_id' => $role_id));
