Laravel validation: ignoring certain fields during update

How can I prevent Laravel from validating certain columns when editing an existing user? I’m trying to update a guest’s information, but I want to ignore the phone and email fields if no changes have been made to the guest’s details. However, when creating a new guest, it should properly check for uniqueness. How can I achieve this? I’ve been struggling with this issue for a while.

Here are my form validation rules:

return [
    'first_name' => 'required|string|max:255',
    'last_name' => 'nullable|string|max:255',
    'other_names' => 'nullable|string|max:255',
    'city' => 'nullable|string|max:255',
    'country' => 'nullable|string|max:255',
    'email' => ['required_if:phone,null', Rule::unique('guests')->whereNot('email',null)->where('hotel_id',auth()->user()->hotel_id) ],
    'phone' => ['required_if:email,null', Rule::unique('guests')->where('phone','!=', $request->phone)->where('hotel_id',auth()->user()->hotel_id) ],
    'address' => 'nullable|string|max:255', 
    'other_phone' => 'nullable|numeric:11',    
];

Any assistance would be greatly appreciated.

    You can use the Rule::unique() method to ignore a certain ID during the validation. This is useful when updating a model and wanting to ignore the model itself.

    use IlluminateValidationRule;

// Assuming $guest is the guest being updated
$guestId = $guest->id;

return [
    'first_name' => 'required|string|max:255',
    'last_name' => 'nullable|string|max:255',
    'other_names' => 'nullable|string|max:255',
    'city' => 'nullable|string|max:255',
    'country' => 'nullable|string|max:255',
    'email' => [
        'required_if:phone,null', 
        Rule::unique('guests')->ignore($guestId)->where(function ($query) use ($request) {
            return $query->where('hotel_id', auth()->user()->hotel_id);
        }),
    ],
    'phone' => [
        'required_if:email,null', 
        Rule::unique('guests')->ignore($guestId)->where(function ($query) use ($request) {
            return $query->where('hotel_id', auth()->user()->hotel_id);
        }),
    ],
    'address' => 'nullable|string|max:255', 
    'other_phone' => 'nullable|numeric:11',    
];

    In the above code, Rule::unique('guests')->ignore($guestId) tells Laravel to enforce the uniqueness.

    Just compare the value to save with the value in the model attribute. E.g.:

    $guest = Guest::firstOrNew(/* ... */);
$new = !$guest->exists;

return [
    ...
    'email' => $new || $guest->email !== $request->email ? [/* validation rules */] : [],
    ...
];
