使用prepared语句在数据库中插入数据时出错

我正在为我的公司使用php和prepared语句的票证系统工作。添加票证时，应填写以下字段：
票证类型
票名
票证描述
请求的日期
请求的小时数
公司
就诊类型
优先
地位
指派的技术人员
这是有效的：1。您可以选择从数据库中提取的票证类型。2您可以从数据库中选择公司。三。您可以选择从数据库中提取的访问类型。4您可以选择从数据库中提取的技术人员。
问题是当你按下add ticket时，它不会向数据库中添加任何内容。
这是我的密码：

更新
对ticketdata.php做了细微的更改，更正了@smith和@nick的观察结果。它们看起来像这样：

class TicketData {
    public static $tablename = "ticket";
    public function TicketData(){
        $this->name = "";
        $this->title = "";
        $this->description= "";
        $this->lastname = "";
        $this->email = "";
        $this->password = "";
        $this->date_at="";
        $this->time_at="";
        $this->tecnico_id="";
        $this->created_at = "NOW()";
    }
    public function getProject(){ return ProjectData::getById($this->project_id); }
    public function getPriority(){ return PriorityData::getById($this->priority_id); }
    public function getStatus(){ return StatusData::getById($this->status_id); }
    public function getKind(){ return KindData::getById($this->kind_id); }
    public function getCategory(){ return CategoryData::getById($this->category_id); }
    public function add(){
        $sql = "insert into ticket (title,description,date_at,time_at,category_id,project_id,priority_id,user_id,status_id,kind_id,created_at,tecnico_id) ";
        $sql .= "values (\"$this->title\",\"$this->description\",\"$this->date_at\",\"$this->time_at\",\"$this->category_id\",\"$this->project_id\",\"$this->priority_id\",\"$this->user_id\",\"$this->status_id\",\"$this->kind_id\",\"$this->created_at\",\"$this->tecnico_id\")";
        return Executor::doit($sql);
    }

现在，它将保存以下字段：
票证类型( kind_id )
票名( title )
票证描述( description )
请求的日期( date_at )
请求的小时数( hour_at )
公司( project_id )
就诊类型( category_id )
优先权( priority_id )
状态( status_id )
它不会保存此字段：
指派的技术人员( tecnico_id )
addticket-action.php文件

<?php
        $r = new TicketData();
        $r->title = $_POST["title"];
        $r->description = $_POST["description"];
        $r->category_id = $_POST["category_id"];
        $r->project_id = $_POST["project_id"];
        $r->priority_id = $_POST["priority_id"];
        $r->user_id = $_SESSION["user_id"];
        $r->status_id = $_POST["status_id"];
        $r->kind_id = $_POST["kind_id"];
        $r->date_at = $_POST["date_at"];
        $r->time_at = $_POST["time_at"];
        $r->tecnico_id = $_POST["tecnico_id"];
        $r->created_at = $_POST["created_at"];
        $r->add();
        Core::alert("Successfully added!");
        Core::redir("./index.php?view=tickets");
 ?>

我想让一切工作之前，消毒和转换成一个适当的准备声明。要使脚本保存( date_at ) ( hour_at )以及( tecnico_id )田地？

提供一些日志或后端错误消息对于解决此问题非常有帮助。
不过，乍一看，最重要的是你并没有使用一个事先准备好的语句。您基本上是将一个字符串连接在一起以生成一个sql语句，这是非常糟糕的，原因有两个：
你很容易受到sql注入的攻击。例如，如果你把 ","",""); DROP TABLE ticket; -- 在您的标题字段中，有人可能会破坏您的票证表，因为您的代码没有对此进行检查。
你需要净化你的输入。如果title包含双引号，它将提前结束字符串输入，导致sql失败。
这是一个相当大的安全漏洞，所以堵上它，同时为自己节省一些输入净化的麻烦！如果您转换为prepared语句并且它可以工作，那么这可能是一个卫生处理问题。如果它仍然不起作用，在那里得到一些日志语句，让我们看看你有什么。
