Answer 1

/**
 * Retrieve an old input item.
 *
 * @param  string  $key
 * @param  mixed   $default
 * @return mixed
 */
 function old($key = null, $default = null)
 {
     return app('request')->old($key, $default);
 }

old()功能有2个参数。第一个是会话，第二个是默认。

所以你可以使用像：

<input id="nom" type="text" class="form-control" name="nom" value="{{ old('nom', $actif->nom) }}" required autofocus>
