How can I redirect with old input in Laravel?

Question

I have a login modal. When the user log-in fail the authentication, I want to redirect back to this modal with :

• error message(s)
• and old input(s).

---

Controller

// if Auth Fail 
return Redirect::to('/')
                ->with('error','Username/Password Wrong')
                ->withInput(Request::except('password'))
                ->withErrors($validator);

---

Form

{!! Form::open(array('url' => '/', 'class' => 'login-form')) !!}

  <div class="form-group">
    <label for="username">Username</label>
    <input type="text" class="form-control"  id="username" name="username" placeholder="Enter Username" required>
  </div>
  <div class="form-group">
    <label for="password">Password</label>
    <input type="password" class="form-control" id="password" name="password" placeholder="Enter Password" required>
  </div>
  <button type="submit" class="btn btn-primary">Login</button>

{!! Form::close() !!}

As you can see as part of my image, the error message seem to display, but the old input of username doesn't seem to populate.

Can someone please correct me ? Did I forget to do anything ? What is the most efficient way in Laravel to accomplish something like this ?

Answer 1

You can access the last inputs like so:

$username = Request::old('username');

As pointed at by @Arian Acosta you may simply do

<input type="text" ... value="{{ old('username') }}" ... >.

As described in the docs it is more convenient in a blade view.

There are several possibilties in the controller:

Instead of ->withInput(Request::except('password'))

do:

a) Input::flash();

or:

b) Input::flashExcept('password');

and redirect to the view with:

a) ->withInput(Input::except('password'));

resp. with:

b) ->withInput();

Answer 2

Try this

 return redirect()->back()
       ->with('error','username is invalid')
       ->withInput();

make sure you have value="{{ old('username') }}" in your input element
