Auth::attempt() Manually Authenticating Users based on NULL condition | Laravel | Passport - laravel

Question

I am creating an application based on Laravel 5.8. I want to manually authentication users based on some checks, But these checks or fields have some null values or not null values.
I follow the official documentation Link
Instead of checking like this
if (Auth::attempt(['email' => $email, 'password' => $password, 'active' => 1])) {
// The user is active, not suspended, and exists.
}
I want to check if some fields that are not null like
if (Auth::attempt(['email' => $email, 'password' => $password, 'activate_on' => 'SomeDateTimeValue Or Not Null' ])) {
}
So it means if the user has some activate_on fields value which should not Null then the Auth::attempt should return true otherwise false.

Answer 1

You can do it by adding your implementation of the UserProvider interface, but that's a lot of work.
I think the easiest way is to do it in two steps.
// first get the user by email
$user = User::whereEmail($email)->first();
if($user->activate_on && Auth::attempt(['email' => $email, 'password' => $password])
{
// logged in
}

I do not believe what you are asking is directly possible. If you take a look at the retrieveByCredentials() method which is called during the attempt() process, the query builder is only set up to accept a value where($key, $value) or an array of values whereIn($key, $value) to conditionally query the user.
public function retrieveByCredentials(array $credentials)
{
if (empty($credentials) ||
(count($credentials) === 1 &&
array_key_exists('password', $credentials))) {
return;
}
// First we will add each credential element to the query as a where clause.
// Then we can execute the query and, if we found a user, return it in a
// Eloquent User "model" that will be utilized by the Guard instances.
$query = $this->newModelQuery();
foreach ($credentials as $key => $value) {
if (Str::contains($key, 'password')) {
continue;
}
if (is_array($value) || $value instanceof Arrayable) {
$query->whereIn($key, $value);
} else {
$query->where($key, $value);
}
}
return $query->first();
}
EDIT:
Sample helper function:
if (!function_exists('attempt')) {
function attempt($credentials, $dates = [], $remember = false)
{
$user = User::where('email',$credentials['email'])->first();
// if a date is null return false
foreach ((array)$dates as $date) {
if (is_null($user->{$date})) {
return false;
}
}
return Auth::attempt($credentials, $remember);
}
}
Usage:
// single date
if (attempt(['email' => $email, 'password' => $password],'activate_on')) {
// ...
}
// array of dates
if (attempt(['email' => $email, 'password' => $password],['activate_on','approve_on'])) {
// ...
}
// no date
if (attempt(['email' => $email, 'password' => $password])) {
// ...
}
