Answer 3

I am calling different validation classes for Store and Update. In my case I don't want to update every fields, so I have baseRules for common fields for Create and Edit. Add extra validation classes for each. I hope my example is helpful. I am using Laravel 4.

Model:

public static $baseRules = array(
    'first_name' => 'required',
    'last_name'  => 'required',
    'description' => 'required',
    'description2' => 'required',
    'phone'  => 'required | numeric',
    'video_link'  => 'required | url',
    'video_title'  => 'required | max:87',
    'video_description'  => 'required',
    'sex' => 'in:M,F,B',
    'title'  => 'required'
);

public static function validate($data)
{
    $createRule = static::$baseRules;
    $createRule['email'] = 'required | email | unique:musicians';
    $createRule['band'] = 'required | unique:musicians';
    $createRule['style'] = 'required';
    $createRule['instrument'] = 'required';
    $createRule['myFile'] = 'required | image';

    return Validator::make($data, $createRule);
}

public static function validateUpdate($data, $id)
{
    $updateRule = static::$baseRules;
    $updateRule['email'] = 'required | email | unique:musicians,email,' . $id;
    $updateRule['band'] = 'required | unique:musicians,band,' . $id;
    return Validator::make($data, $updateRule);
}

Controller: Store method:

public function store()
{
    $myInput = Input::all();
    $validation = Musician::validate($myInput);
    if($validation->fails())
    {
        $key = "errorMusician";
        return Redirect::to('musician/create')
        ->withErrors($validation, 'musicain')
        ->withInput();
    }
}

Update method:

public function update($id) 
{
    $myInput = Input::all();
    $validation = Musician::validateUpdate($myInput, $id);
    if($validation->fails())
    {
        $key = "error";
        $message = $validation->messages();
        return Redirect::to('musician/' . $id)
        ->withErrors($validation, 'musicain')
        ->withInput();
    }
}

You can trying code bellow

return [
    'email' => 'required|email|max:255|unique:users,email,' .$this->get('id'),
    'username' => 'required|alpha_dash|max:50|unique:users,username,'.$this->get('id'),
    'password' => 'required|min:6',
    'confirm-password' => 'required|same:password',
];

Unique Validation With Different Column ID In Laravel

'UserEmail'=>"required|email|unique:users,UserEmail,$userID,UserID"

Answer 6

For a custom FormRequest and Laravel 5.7+ you can get the id of your updated model like this:

public function rules()
    {
        return [
            'name' => 'required|min:5|max:255|unique:schools,name,'.\Request::instance()->id
        ];
    }
