Laravel Application Helper: old

old($key = null, $default = null)

The old helper function is used to retrieve an old input item. It is a shortcut to calling the Illuminate\Http\Request::old instance method. It accepts a $key argument and a $default argument. They $key should be the name of the input item to retrieve and a $default value can be supplied that will be returned if the given $key does not exist.

The following example demonstrates how to use the old helper function and assumes that an input item with the key name exits:

1<?php
2 
3// Retrieve the old name.
4$userName = old('name');
5 
6// Retrieve the old name with
7// a default value.
8$userName = old('name', 'John Doe');

The examples below demonstrate different methods to achieve the same result:

 1<?php
 2 
 3use Illuminate\Facades\Input;
 4 
 5// Retrieve the old name using the Input facade:
 6$userName = Input::old('name');
 7 
 8// Retrieve the old name using the request()
 9// helper function:
10$userName = request()->old('name');
