I am trying to do

<input name="name" type="text" placeholder="Your Name" value="{{ Input::old('name') }}">

but keep getting this error:

Unexpected token "punctuation" of value ":" ("end of print statement" expected)

Is there a way to retrieve old input for a form? In L5 there is function called old but it is missing here somehow.

This should help: https://octobercms.com/docs/services/html#form-model-binding

So I tried doing input_old but it says:

Unknown "input_old" function.

This is really bothersome. Why are all examples from documentation not working??

So I tried doing input_old (...) Why are all examples from documentation not working??

The docs state snake case should be used for Html/form facade, so:

<input ... value="{{ form_value('name') }}">

Remember - its October, not Laravel. ;-)

I have figured out a way of working with october by using ajax controller, but now I am curious why does this not work.

@mario.basic1089 Twig is a sandboxed language. You must pass it all the data/objects you want it to have access to before you start. see https://octobercms.com/docs/cms/pages#page-variables

In your case use:

//ini section
=========
//code section
public function onStart(){
$this->page['name'] = Input::old('name');
}
=========
<input name="name" type="text" placeholder="Your Name" value="{{ name }}">
