Check out this question. You can use

email'  =>  'required|email|unique:users,email,'.$user->id

@mstnorris thanks man, but IMHO I don't see difference between the above rule and mine?

You'll have to show more code as to how you're passing the ID through in order for us to help you. Did you check out the linked question?

@mstnorris Ok. I am not using Form request validation as I'm using laravel as an API where the front end is a javascript application. Here is my code:

I have a validator class like this:

use InvalidInputException;
use Illuminate\Validation\Factory as Validator;

class UserValidator
{
    protected $validator;

    public function __construct(Validator $validator)
    {
        $this->validator = $validator;
    }

    public function rules($id)
    {
        return [
            'name'  =>  'required',
            'email'  =>  'required|unique:users,id,'.$id,
            'password'  =>  'required'
        ];
    }

public function validate(array $input, $id = 0)
    {
        $validator = $this->validator->make($input, $this->rules($id));
        
        if($validator->fails()) throw new InvalidInputException();
    }
}

And I have a repository class for database operations:

class UserRepository extends Repository
{
   protected $validator;
   public function __construct(UserValidator $validator)
    {
        $this->validator = $validator;
    }  

   public function update(array $attributes, $id)
    {
        $this->validator->validate($attributes, $id);
        //----Rest of the code
    }
}

@binalfew Try changing this line:

class UserValidator
{
    protected $validator;

    public function __construct(Validator $validator)
    {
        $this->validator = $validator;
    }

    public function rules($id)
    {
        return [
            'name'  =>  'required',
            'email'  =>  'required|unique:users,email,'.$id, // <--- THIS LINE
            'password'  =>  'required'
        ];
    }

public function validate(array $input, $id = 0)
    {
        $validator = $this->validator->make($input, $this->rules($id));
        
        if($validator->fails()) throw new InvalidInputException();
    }
}

@rodrigo.pedra Thank you for taking the time to answer. To what should I change it, please?

In the code you posted you had this line:

'email'  =>  'required|unique:users,id,'.$id, // note the id field

I suggested to change to this:

'email'  =>  'required|unique:users,email,'.$id, // note the email field

If you look into the docs [ http://laravel.com/docs/5.1/validation#rule-unique ], you'll see that the second argument is the table field which the value should be unique.

what if the roles array is defined in the model ??

@CyrusGreat The old way also working, I tried it on 5.3!

@CyrusGreat You should write this in your controller. Here $data represents your $request. You can write the above code like this in the controller.

$this->validate($request, [
    'email' => [
        'required',
        Rule::unique('users')->ignore($user->id),
    ],
]);

hi i am new in laravel . i have some questions . Is it possible to write more line for validate? for example : $this->validate($request, [ 'email' => [ 'required', Rule::unique('users')->ignore($user->id), ], another parameter => [ .... ], another parameter => [ .... ], ]);

and another question if i want to use RequestFile to check validation how pass the id for ignoring?

the third question : can i use this rule for one of the inputs and for the rest use Request file? how can i understand that the validate was true , for example if the validate true check the request file rules .

last question : which one is better Request file or validate this way in controllers ?

THIS IS AN EASY SOLUTION

Just add $this->route('id') as the third parameter

if your route was defined like this:

Route::put('{company}', 'CompanyController@update')
            ->name('update');

then your parameter name is "company"

So in your FormRequest:

    public function rules()
    {
        $rules = [
            'url' => [
                'required',
                'url',
                'unique:companies,url,'.$this->route('company') ?? 0
            ],    
        ];
        // dd($rules); << check yourself

        return $rules;
    }

This FormRequest works the same for insert or update.

this line will instruct to ignore "0" in case of insert

$this->route('company') ?? 0

@eduardoarandah

This is a three year old thread...

thanks @eduardoarandah , this looks like a right solution.

if your primary key is not named 'id' In my case my primary key is user_id and table name is users_table and I want to update user_name

so I do it this way

'user_name' => 'required|unique:users_table,user_name,'.$id.',user_id'

This snippet may be useful if you're using a FormReqest. This will ensure the name is unique, ignore the existing record and also ignore any soft deleted records.

 public function rules()
    {
        return [
            'name' => [
                'required',
                'email',
                Rule::unique('users', 'email')
                    ->where(static function ($query) {
                        return $query->whereNull('deleted_at');
                    })
                    ->ignore($this->user),
            ]
        ];
    }
