非常有线。选择代码工作正常，但插入查询没有。怎么了？

你需要告诉PDO上升错误
setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
答案 1 :(得分：0)
您已将INSERT查询字符串分配给var，但未在其上执行$db->query($sql);。
在
$sql = " INSERT INTO sponsors (naam, site, img, opbrengst, duur) VALUES ('".$naam.", ".$site.", ".$img.", ".$opbrengst.", ".$duur."')";
添加
$db->query($sql);
