它没有显示任何错误或错误，请帮助哈哈这里是我的所有代码让我更容易查看和帮助我希望大声笑

Answer 1

我认为username和name是您的表格列，因此请尝试

$validUser = mysqli_real_escape_string($con, $_SESSION['username']);
mysqli_query("SELECT * FROM users WHERE username ='$validUser' LIMIT 1");
if (mysqli_connect_errno()) {
   echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con, "SELECT level, exp, maxexp, str, dex, inte, sta, crit, hp, atk, def, dfire, dwater, dposion, atkfire, atkwater, atkposion, weapon FROM users WHERE username = '$validUser'");
$data = mysqli_fetch_array($result,MYSQLI_ASSOC);
$weapon = $data['weapon'];
$weaponQ = mysqli_query($con, "SELECT * FROM equipment WHERE wname= '$weapon'") or die(mysqli_error($con)); 
if(mysqli_num_rows($weaponQ) > 0) {
  $weaponF = mysqli_fetch_array($weaponQ,MYSQLI_ASSOC);
}
else {
  echo 'No rows found';
}
mysqli_close($con);

并且也没有以下查询的工作，因此您可以删除它： -

 mysqli_query("SELECT * FROM users WHERE username ='$validUser' LIMIT 1");

没有第二次获取
