Laravel Add Custom Conditions While Login
----------------------------------------------

Add custom condition while login in laravel.

I made it work by directly adding condition in AuthenticatesUsers trait

If you go inside the following folder 

/vendor/laravel/framework/src/Illuminate/Foundation/Auth

and open the file AuthenticatesUsers.php

Once you open the file you can see protected function credentials(Request $request){} method is this where you can add condition

Like.

/**
     * Get the needed authorization credentials from the request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    protected function credentials(Request $request)
    {
        $credentials = $request->only($this->username(), 'password');
        $credentials = array_add($credentials, 'frontend_regsitered', '1');
        return $credentials;
    }

So add you can see i have added frontend_regsitered as 1 custom condition while login.
