I Want to read a pareameter from parameters.yml. the solution is to extend the Controller but I got this error :
Error: Call to a member function getParameter() on null
I know that the container is null, but i don't know how to get the container?
class Configuration extends Controller
{
public function __construct()
{
$this->tempFolderPath = sys_get_temp_dir();
$parameter = $this->container->getParameter('a');
}
}
Any solution ? Any help ?
我想从parameters.yml读取一个pareameter。 解决方案是扩展Controller但我收到此错误 ：
错误：在null上调用成员函数getParameter（）
我知道容器是 null，但我不知道如何获取容器？
class Configuration extends Controller
{
public function __construct（）
{
$ this- ＆gt; tempFolderPath = sys_get_temp_dir（）;
$ parameter = $ this-＆gt; container-＆gt; getParameter（'a'）;
}
}
< p>任何解决方案？ 有什么帮助吗？
this is not a best practice, but for me this is the only solution :( because in my code I have a static method that instantiate the hole class. so the solution will be.
微信扫一扫public function __construct()
{
$this->tempFolderPath = sys_get_temp_dir();
global $kernel;
$this->host = $kernel->getContainer()->getParameter('ws_host');
}
