Answer 1

It should work
return [
'email' => "required|email|unique:clients,email,".request('id'),
'client_type_text' => 'required',
'client_name' => 'required',
'phone_number' => 'required',
'contacts' => 'required|array',
'contacts.*.firstname' => 'required',
'contacts.*.lastname' => 'required',
'contacts.*.mobile' => 'required',
// check if email is unique for each contact id
'contacts.*.email' => [
'required',
'email',
function ($attribute, $value, $fail) {
$contact_id = explode('.', $attribute)[1];
$client_id = request('id');
$contact = \App\Models\Contact::where('id', $contact_id)->where('client_id', $client_id)->first();
if ($contact) {
$contact_email = $contact->email;
if ($contact_email != $value) {
$contact_with_email = \App\Models\Contact::where('email', $value)->first();
if ($contact_with_email) {
$fail('The email has already been taken.');
}
}
}
},
],
];
