Question

在视图文件中

action =“{{route（'uploadfile'，['file_id'=＆gt; 1]）}}”method =“post”＆gt;

在路线档案中

Route::post('/uploadfile',['uses'=>'FileController@uploadfile','as'=>'uploadfile']);

在控制器中

 public function uploadfile($file_id)
{

}

我的问题是：我如何从视图获取值到控制器而不使用post方法将它们显示到url中它会给出错误。

您无法像这样传递变量。您可以使用此方法提交值

在视图文件中

    <?xml version="1.0" encoding="UTF-8"?>

在控制器中

//user[preceding-sibling::video/uploader[avg((following-sibling::ratings/rating/@value))>=3]/text()=//user/email/text()]

试试这个
