// laravel validation regex exists example 'member_id' => 'required|exists:members,id' // laravel custom validation unique example 'email' => 'required|unique:members,email'
We can also simple use the PHP Based Laravel Rule class to main class define the jquery rule data fluently.
use Illuminate\Validation\Rule;
Validator::make($data, [
'email' => [
'required',
Rule::exists('members')->where(function ($query) {
$query->where('status', 1);
}),
],
]);
