文件名不能为空

Question

几个星期前，我有这个代码将文件上传到我的数据库，但现在不起作用

输入：

上传文件的.php（与数据库的连接）

function(doc) {
{ if (doc.type === 'conference') {
    if(doc.timeslots.size !==0 ){
            emit( null, doc);
        }
    }
  }
}

Answer 1

哪里显示错误？在插入？如果你说它过去有效，那么表格的结构可能会改变。

Answer 2

您有一个浏览文件的按钮。您需要另一个发布表单。像

这样的东西

echo "<input $class type='submit' value='submit' name='$name' id='$name'>"
