我正在使用PDO將數據保存到數據庫，但數據似乎沒有保存，再加上它也不會引發錯誤。 我使用Android的OKhttp3類將POST請求發送到我的PHP文件chatroom.php。數據不會保存在使用PDO的數據庫中
<?PHP
include("PDOConnection.php");
//Define some value
define("ACTION_ADD_ROOM","addRoom");
define("ACTION_SELECT","select");
define("RESULT_SUCCESS",0);
define("RESULT_ERROR",1);
define("RESULT_ROOM_EXISTS",2);
$action=$_POST["action"];
$result=RESULT_ERROR;
if(isset($action))
{
if($action==ACTION_ADD_ROOM)
{
$name=$_POST["name"];
$chatdesc=$_POST["chatdesc"];
if(isset($_FILES['chatImage']))
$image=$_FILES['chatImage']['name'];
}
else if($action==ACTION_SELECT)
{
$Id=$_POST["id"];
}
if(ACTION_ADD_ROOM==$action)
{
//check exists Room
if(isExistRoom($cnn,$name))
{
$result=RESULT_ROOM_EXISTS;
}
else
{
insertChatroom($cnn,$name,$chatdesc,$image);
$result=RESULT_SUCCESS;
}
}
else if(ACTION_SELECT==$action)
{
if(login($cnn,$Id))
{
$result=RESULT_SUCCESS;
//login success
}
else
{
//login fail
$result=RESULT_ERROR;
}
}
if((isset($_FILES['chatImage']) && $result==RESULT_SUCCESS && ACTION_ADD_ROOM==$action))
{
$errors= array();
$file_name = $_FILES['chatImage']['name'];
$file_size =$_FILES['chatImage']['size'];
$file_tmp =$_FILES['chatImage']['tmp_name'];
$file_type=$_FILES['chatImage']['type'];
$expensions= array("jpeg","jpg","png");
if(empty($errors)==true)
{
$id=returnID($cnn,$name);
if(!is_dir("uploads/Rooms/".$id))
mkdir("uploads/Rooms/".$id, 0700);
move_uploaded_file($file_tmp,"uploads/Rooms/".$id."/".$file_name);
}else{
print_r($errors);
}
}
}
echo $result;
function insertChatroom($cnn,$name,$chatdesc,$image)
{
try
{
$query = "INSERT INTO chatroom (name, 'chatdesc', image) VALUES(?, ?, ?)";
$stmt = $cnn->prepare($query);
$stmt->execute([$name, $chatdesc, $image]);
}
catch(\PDOException $e)

}
}
function isExistRoom($cnn,$name)

return $rowcount;

function login($cnn,$Email,$Password)
{

}
function returnID($cnn,$name)

$stmt=$cnn->prepare($query);

我覺得有使用或於Android，但以防萬一一個HTML頁面發送POST要求之間沒有什麼不同，這裏是我的Android代碼：

爲什麼你不開始簡單的POST例子，看看它的工作，然後我們可以調試/檢查你的代碼。 – samayo
