############## Example : ################
############### For Updating
//rules
'email' => 'unique:users,email_address,' . $userId,
############### For Creating
//rules
'email' => 'unique:users,email_address',Just a side note, most answers to this question talk about email_address while in Laravel's inbuilt auth system, the email field name is just email. Here is an example how you can validate a unique field, i.e. an email on the update:
In a Form Request, you do like this:
public function rules()
{
return [
'email' => 'required|email|unique:users,email,'.$this->user->id,
];
}
Or if you are validating your data in a controller directly:
public function update(Request $request, User $user)
{
$request->validate([
'email' => 'required|email|unique:users,email,'.$user->id,
]);
}
Update: If you are updating the signed in user and aren't injecting the User model into your route, you may encounter undefined property when accessing id on $this->user. In that case, use:
public function rules()
{
return [
'email' => 'required|email|unique:users,email,'.$this->user()->id,
];
}
A more elegant way since Laravel 5.7 is:
public function rules()
{
return [
'email' => ['required', 'email', \Illuminate\Validation\Rule::unique('users')->ignore($this->user()->id)]
];
}
