How to ignore unique validation when updating fields in laravel8? - php

Question

I currently use Laravel 8 and I want to know how do I ignore unique validation when a user is updating their profile? If the user is updating every field except the pageName I don't want it to throw a vaildation error cause the user is already the owner of that pageName. I tried this code but it gives error: ErrorException
Undefined variable: user
$request->validate([
'image' => 'nullable|mimes:jpeg,jpg,png|max:100',
'pageName' => 'nullable|alpha_dash|unique:users,littlelink_name'.$user->id,
'pageColor' => 'nullable',
'pageFontcolor' => 'nullable',
'pageDescription' => 'nullable|regex:/^[\w.\- ]+$/i',
'pagePixiv' => 'nullable|url',
]);
This is my controller
<?php

Anyone know how to fix this?

Answer 1

You can change your code to the following
$userId = Auth::user()->id;
$request->validate([
'image' => 'nullable|mimes:jpeg,jpg,png|max:100',
'pageName' => 'nullable|alpha_dash|unique:users,littlelink_name,'.$userId,
'pageColor' => 'nullable',
'pageFontcolor' => 'nullable',
'pageDescription' => 'nullable|regex:/^[\w.\- ]+$/i',
'pagePixiv' => 'nullable|url',
]);

Answer 2

you can use the Rule object to make that validation:
'pageName' => ['nullable','alpha_dash', Rule::unique('users','littlelink_name')->ignore($user->id)
