Question

我试图将值添加到phpmyadmin中的表中，但出现错误：“字段列表”中的未知列“ ...”。

$SELECT = "SELECT * FROM battle WHERE time2 < (NOW() - INTERVAL 1400 MINUTE)";

$fire5 = mysqli_query($con,$SELECT)or die(mysqli_error($con));
if (mysqli_num_rows($fire5)>0) {
while($users = mysqli_fetch_assoc($fire5)){
  $nowvote = $users['vote'];
  $nowvote2 = $users['vote2'];
  $userid1 = $users['id1'];
  $userid2 = $users['id2'];
  $username1 = $users['username'];
  $username2 = $users['username2'];
  $time2 = $users['time2'];
  $avatarpath1 = $users['avatar_path1'];
  $avatarpath2 = $users['avatar_path2'];
  $query ="SELECT * from users where id=$userid1";
$fire = mysqli_query($con,$query)or die(mysqli_error($con));
if (mysqli_num_rows($fire)>0) {
  $users= mysqli_fetch_assoc($fire); 
    $win = $users['win'];
     $userid1 = $users['id'];


}
$query2 ="SELECT * from users where id=$userid2 ";
$fire2 = mysqli_query($con,$query2)or die(mysqli_error($con));
if (mysqli_num_rows($fire2)>0) {
  $users= mysqli_fetch_assoc($fire2); 
    $win1 = $users['win'];
    $userid2 = $users['id'];



}
  if ($nowvote>$nowvote2) {

    mysqli_query($con,"UPDATE users SET win=$win1+1 where id = '$userid2'");
     mysqli_query($con, "INSERT INTO winner(avatar_path, username,user_id) VALUES ('$avatarpath1','$username2','$userid2')")or die(mysqli_error($con));

  }elseif($nowvote2>$nowvote){

    mysqli_query($con,"UPDATE users SET win=$win+1 where id = '$userid1'");
       mysqli_query($con, "INSERT INTO winner(avatar_path, username,userid) VALUES ('$avatarpath2','$username1','$userid1')")or die(mysqli_error($con));

  }

  }

因此，当我执行查询时，我得到：'字段列表'中的未知列'userid'。这以前从未发生过，我也不知道发生了什么。

不是你的最后一个

mysqli_query($con, "INSERT INTO winner(avatar_path, username,userid) VALUES ('$avatarpath2','$username1','$userid1')")or die(mysqli_error($con));

是

mysqli_query($con, "INSERT INTO winner(avatar_path, username,user_id) VALUES ('$avatarpath2','$username1','$userid1')")or die(mysqli_error($con));

userid ==> user_id？

字段列表中的未知列。
