<?php
if(isset($_POST['submit']))
$token = $_POST['token'];
$cat = $_POST['cat'];
$ads = $_POST['ads'];
$key = $_POST['keyboard'];
$tel = new Telegram();
$notice = $tel->AddNew($token,$cat,$ads,$key);
?>
<div class='content-wrapper'>
<section class='content-header'>

<ol class='breadcrumb'>
<li class='active'>telegram.php</li>
</ol>

if($dataSet->GetLevel()==1)
echo "

if(isset($notice['success_message']))
echo "
<div class='alert alert-success'>
<strong>Hey!</strong> ".$notice['success_message'].".
</div>
";
echo "
<form role='form' method='POST' action=''>

<div class='box-footer'>

else
echo "
<section class='content'>
<div class='alert alert-warning'>
<strong>Access Denied!</strong> You don\'t have permission to access this page.
</div>
</section> ";
?>
</div>
正如你在顶部所看到的，我调用了一个名为 Telegram.class.php 的类，这个类是这样的：
<?php
class Telegram
protected $notice = array();
private $db;
public function __construct()
$this->db = new Connection();
$this->db = $this->db->dbConnect();
public function AddNew($token,$cat,$ads,$key)
if(!empty($token)&&!empty($cat)&&!empty($ads))
for ($i=0;$i<sizeof($ads);$i++)
for ($i=0;$i<sizeof($key);$i++)
$new = $this->db->prepare("INSERT INTO channels (token_number, category_name, ads_set, keyboard_status) VALUES (?, ?, "/*.$ads[$i].*/", "/*.$key[$i].*/")");
$new->bindParam(1,$token);
$new->bindParam(2,$cat);
$new->bindParam(3,$ads);
$new->bindParam(4,$key);
$new->execute();
$notice['success_message'] = "New Telegram Channel was successfully added";
return $this->notice;
public function getNotice()
return $this->notice;
?>
因为我想在表格中添加多个复选框，所以我在方法Add_New中使用了这个for循环（根据question）：
for ($i=0;$i<sizeof($ads);$i++)
for ($i=0;$i<sizeof($key);$i++)
$new = $this->db->prepare("INSERT INTO channels (token_number, category_name, ads_set, keyboard_status) VALUES (?, ?, "/*.$ads[$i].*/", "/*.$key[$i].*/")");
$new->bindParam(1,$token);
$new->bindParam(2,$cat);
$new->bindParam(3,$ads);
$new->bindParam(4,$key);
$new->execute();
$notice['success_message'] = "New Telegram Channel was successfully added";
return $this->notice;
我知道这不正确，但我不知道将这些 $ads[$i] 和 $key[$i] 变量添加到插入语句...
如果您知道如何按正确的顺序执行此操作，请告诉我.. 谢谢！
【问题讨论】：
【参考方案1】：利用构造函数
首先，您的addNew 函数可以真正理解为“创建此对象的新实例”，这确实是__construct 的工作。这里的另一个问题是Telegram 对象必须创建多个实例。但是，调用$tel = new Telegram(); 意味着只有一个 对象实例。因此，您嵌套的 for 循环应该属于脚本页面，而不是对象内部。
重构数据库连接
目前，您的数据库连接正在对象内初始化。现在您的对象有两个职责：管理电报和与数据库通信。我建议在 Telegram 之外创建连接对象，并尽可能保持面向对象，将其传递给对象。 This answer 很好地解释了这部分。
分解一些功能
现在，对象的构造函数正在做两件事：创建对象的实例，并将其持久化到数据库中。理想情况下，您希望这两个进程彼此分离。这允许您创建Telegram 的实例并在将其保存到数据库之前对其执行验证，从而使您的构造函数保持整洁。
电报类：
<?php
class Telegram
protected $notice = '';
private $_token;
private $_cat;
private $_ads;
private $_key
public function __construct($token, $cat, $ads, $key)
$this->_token = $token;
$this->_cat = $cat;
$this->_ads = $ads;
$this->_key = $key;
public function saveToDb(PDO $con)
$new = $this->con->prepare("INSERT INTO channels (token_number, category_name, ads_set, keyboard_status) VALUES (?, ?, "/*.$ads[$i].*/", "/*.$key[$i].*/")");
$new->bindParam(1,$this->_token);
$new->bindParam(2,$this->_cat);
$new->bindParam(3,$this->_ads);
$new->bindParam(4,$this->_key);
$new->execute();
$this->notice['success_message'] = "New Telegram Channel was successfully added";
return $this->notice;
public function getNotice()
return $this->notice;
public function getToken()
return $this->_token;
public function getCat()
return $this->_cat;
public function getAds()
return $this->_ads;
public function getKey()
return $this->_key;
?>
表单脚本：
<?php
if(isset($_POST['submit']))
$db = new Connection();
$db = $this->db->dbConnect();
$token = $_POST['token'];
$cat = $_POST['cat'];
$ads = $_POST['ads'];
$key = $_POST['keyboard'];
$notices = array();
if(!empty($token)&&!empty($cat)&&!empty($ads))
for ($i=0; $i < count($this->_ads); $i++)
for ($j=0; $j < count($this->_key);$j++)
$tel = new Telegram($token, $cat, $ads[$i], $key[$j]);
$notices[] = $tel->saveToDb($db); // keep a notice for each object created
?>
<div class='content-wrapper'>
/* ... */
【讨论】：
【参考方案2】：简单地使用 PHP 的 implode 和 explode 函数。在保存数据时，像下面这样内爆它：
$key = implode(", ", $_POST['keyboard']);
$tel = new Telegram();
$notice = $tel->AddNew($token,$cat,$ads,$key);
根据需要替换 implode ", " 的第一个参数。
为了显示使用爆炸如下： $id = explode(", ", $DbRes->keyboard);
一旦将数组转换为字符串，就无需在类中循环。查看更新的类代码如下：
<?php
class Telegram
protected $notice = array();
private $db;
public function __construct()
$this->db = new Connection();
$this->db = $this->db->dbConnect();
public function AddNew($token,$cat,$ads,$key)
if(!empty($token)&&!empty($cat)&&!empty($ads))
$new = $this->db->prepare("INSERT INTO channels (token_number, category_name, ads_set, keyboard_status) VALUES (?, ?, ".$ads.", ".$key.")");
$new->bindParam(1,$token);
$new->bindParam(2,$cat);
$new->bindParam(3,$ads);
$new->bindParam(4,$key);
$new->execute();
$notice['success_message'] = "New Telegram Channel was successfully added";
return $this->notice;
public function getNotice()
return $this->notice;
?>
这将帮助您加深理解。您需要将数组转换为字符串，以便 mysql 数据库可以存储它。这篇文章也有帮助：Save PHP array to MySQL?
【讨论】：
那么类呢，类文件没有变化？ 是的，课程将被更改。如果值已转换为字符串，则无需在数组上循环。答案已更新。以上是关于如何使用 PHP OOP 插入多个单选按钮值的主要内容，如果未能解决你的问题，请参考以下文章
