我第一次有一个模型视图控制器（MVC）项目，完成该项目后，它可以在本地PHP版本7.3.9服务器（Xampp）上正常运行，但是一旦我托管在远程服务器上。模型函数之一，例如mdlAddUser（$ table，$ data）无法插入数据库。该模型中的其他功能在远程服务器和脱机状态下均可正常运行。
mdlAddUser（）继续返回“错误”消息，这意味着插入失败。
我需要帮助，以便可以成功将用户添加到数据库。提前致谢 。
这是我的标准代码：
require_once“ connection.php”;
Class UsersModel {
/*=============================================
SHOW USER
=============================================*/
static public function MdlShowUsers($tableUsers, $item, $value){
if($item != null){
$stmt = Connection::connect()->prepare("SELECT * FROM $tableUsers WHERE $item = :$item");
$stmt -> bindParam(":".$item, $value, PDO::PARAM_STR);
$stmt -> execute();
return $stmt -> fetch();
}
else{
$stmt = Connection::connect()->prepare("SELECT * FROM $tableUsers");
$stmt -> execute();
return $stmt -> fetchAll();
}
$stmt -> close();
$stmt = null;
}
/*=============================================
ADD USER
=============================================*/
static public function mdlAddUser($table, $data){
$stmt = Connection::connect()->prepare("INSERT INTO $table(name, user, password, profile, photo) VALUES (:name, :user, :password, :profile, :photo)");
$stmt -> bindParam(":name", $data["name"], PDO::PARAM_STR);
$stmt -> bindParam(":user", $data["user"], PDO::PARAM_STR);
$stmt -> bindParam(":password", $data["password"], PDO::PARAM_STR);
$stmt -> bindParam(":profile", $data["profile"], PDO::PARAM_STR);
$stmt -> bindParam(":photo", $data["photo"], PDO::PARAM_STR);
if ($stmt->execute()) {
return "ok";
} else {
return "error";
}
$stmt -> close();
$stmt = null;
}
/*=============================================
EDIT USER
=============================================*/
static public function mdlEditUser($table, $data){
$stmt = Connection::connect()->prepare("UPDATE $table set name = :name, password = :password, profile = :profile, photo = :photo WHERE user = :user");
$stmt -> bindParam(":name", $data["name"], PDO::PARAM_STR);
$stmt -> bindParam(":user", $data["user"], PDO::PARAM_STR);
$stmt -> bindParam(":password", $data["password"], PDO::PARAM_STR);
$stmt -> bindParam(":profile", $data["profile"], PDO::PARAM_STR);
$stmt -> bindParam(":photo", $data["photo"], PDO::PARAM_STR);
if ($stmt->execute()) {
return 'ok';
} else {
return 'error';
}
$stmt -> close();
$stmt = null;
}
/*=============================================
EDIT USER
=============================================*/
static public function mdlEditUserStudent($table, $data){
$stmt = Connection::connect()->prepare("UPDATE $table set phone = :phone, password = :password, address = :address, photo = :photo WHERE id = :idStudent");
$stmt -> bindParam(":phone", $data["phone"], PDO::PARAM_STR);
$stmt -> bindParam(":idStudent", $data["idStudent"], PDO::PARAM_INT);
$stmt -> bindParam(":password", $data["password"], PDO::PARAM_STR);
$stmt -> bindParam(":address", $data["address"], PDO::PARAM_STR);
$stmt -> bindParam(":photo", $data["photo"], PDO::PARAM_STR);
if ($stmt->execute()) {
return 'ok';
} else {
return 'error';
}
$stmt -> close();
$stmt = null;
}
}
这是我的控制器代码

$photo = "";

list($width, $height) = getimagesize($_FILES["newPhoto"]["tmp_name"]);
$newWidth = 500;
$newHeight = 500;

}
}else{

/*=============================================

=============================================*/
static public function ctrShowUsers($item, $value){
$table = "users";
$answer = UsersModel::MdlShowUsers($table, $item, $value);
return $answer;
}
}
这是我从包含HTML表单的View中调用adduser函数的方式
$createUser = new ControllerUsers();
$createUser -> ctrCreateUser();
