How to redirect back to form with input - Laravel 5

write old function on your fields value for example

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

In your HTML you have to use value = {{ old('') }}. Without using it, you can't get the value back because what session will store in their cache.

Like for a name validation, this will be-

<input type="text" name="name" value="{{ old('name') }}" />

Now, you can get the value after submitting it if there is error with redirect.

return redirect()->back()->withInput();

As @infomaniac says, you can also use the Input class directly,

return Redirect::back()->withInput(Input::all());

Add: If you only show the specific field, then use $request->only()

return redirect()->back()->withInput($request->only('name'));

Hope, it might work in all case, thanks.

You can use the following:

return Redirect::back()->withInput(Input::all());

If you're using Form Request Validation, this is exactly how Laravel will redirect you back with errors and the given input.

Excerpt from \Illuminate\Foundation\Validation\ValidatesRequests:

return redirect()->to($this->getRedirectUrl())
                    ->withInput($request->input())
                    ->withErrors($errors, $this->errorBag());
