Laravel 5 Update Validation email needs to be unique - php

Question

I'm trying to update a user, as an admin.
I'm changing the username, but it says email must be unique.
How do I fix this.
public function update($id, PutUser $request)
{
if (auth()->id() == $id) {
return redirect()->back()->withFlashDanger('Permission Denied, You can not edit own profile here.');
}
$user = User::find($id);
$user->update((array_merge($request->validated(), ['county' => request('county')])));
//Update model_has_roles model with assignees_roles
return redirect()->route('users.index')->withFlashSuccess(trans("alerts.users.updated"));
}
This is the request class
public function authorize()
{
return true;
}
public function rules()
{
$user_id = $this->input('id');
return [
'name' => 'required|string',
'username' => 'required',
'email' => 'required|email|unique:users,email'.$user_id,
'gender' => 'required',
'phone' => 'sometimes|numeric',
'address' => 'sometimes|string',
'country_id' => 'required',
];
}
}
I keep getting a failed email validation. 'Email has already been taken'. Any idea

Answer 1

You are missing a comma after the email label in your validation:
return [
'name' => 'required|string',
'username' => 'required',
'email' => 'required|email|unique:users,email,'.$user_id,
'gender' => 'required',
'phone' => 'sometimes|numeric',
'address' => 'sometimes|string',
'country_id' => 'required',
];
Since Laravel 5.3 (I believe), you can also use rule builders for more descriptive validation rules. Those are better to read and interpret for humans so it would result in a lower error rate:
use Illuminate\Validation\Rule;
return [
'email' => [
'required',
Rule::unique('users', 'email')->except($user_id),
]
];
