Question

我试图将fileDetailsID这是mysql数据库FileDetails表中的主键放入文件中。当一个用户上传时，文件的详细信息将相互附加。

如果我将'$_SESSION[login_user]'放入$fsql的值中，我会获得当前用户的userID，因此我可以假设上传到数据库的工作正常。

我已就此网站上的先前问题尝试过很多建议，但没有任何效果。虽然我可能做错了，因为我是pvp的新手。

我想我很亲近，这就是我必须获得我想要的主键

  $fses_sql = mysqli_query($conn,"SELECT fileDetailID FROM FileDetails WHERE userID = '$_SESSION[login_user]' ");

这是传递给

的内容

 $fsql = "INSERT INTO files (fileDetailID) VALUES ('$fses_sql')";

        if (mysqli_query($conn, $fsql)) {
        $info = "file uploaded Successfully!";
      } else {
        $info ="Unable to Add file!";
      }

但我收到此错误

我已更改此内容并将输入更改为$ ressult1

$fses_sql = mysqli_query($conn,"SELECT fileDetailID FROM FileDetails WHERE userID = '$_SESSION[login_user]'[, string $ressult1 = MYSQLI_STORE_RESULT ] ");

错误已经消失，但我想填充的字段现在没有任何内容
