how to check if a cookie is set in laravel?
提问by Jim Peeters
I have made a cookie with my controller and this seems to work because if I check my resources in my developer tools it is there. But now I want to do actions with it in my view , but this doesn't seem to work , this is the code I used in my view:
我用我的控制器制作了一个 cookie，这似乎有效，因为如果我在我的开发人员工具中检查我的资源，它就在那里。但是现在我想在我的视图中对其进行操作，但这似乎不起作用，这是我在视图中使用的代码：
@if (Cookie::get('cookiename') !== false)
<p>cookie is set</p>
@else
<p>cookie isn't set</p>
@endif
this is always returning 'true'
这总是返回“真实”

If you check out the Cookie class now you can use Cookie::has('cookieName');
如果您现在查看 Cookie 类，则可以使用 Cookie::has('cookieName');
class Cookie extends Facade
{
/**
* Determine if a cookie exists on the request.
*
* @param string $key
* @return bool
*/
public static function has($key)
{
return ! is_null(static::$app['request']->cookie($key, null));
}
// ...
