Question

我正在使用PHP OOP编写的CMS项目。对于这个项目，我想添加一个管理员可以添加Telegram Bot并管理它们的部分。所以我在页面telegram_section.php中创建了这个表单：

    <?php 
if(isset($_POST['submit'])){
    $db = new Connection();
    $connection = $db->dbConnect();

    $token = $_POST['token'];
    $cat = $_POST['cat'];
    $ads = $_POST['ads'];
    $key = $_POST['keyboard'];

    $notice = 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]);
                $notice[] = $tel->saveToDb($db); 
            }
        }
    }
}
?>
<div class='content-wrapper'>
    <section class='content-header'>
        <h1>
            Add New Telegram Account
            <small>You can add a new Telegram channel here</small>
        </h1>
        <ol class='breadcrumb'>
            <li class='active'>telegram.php</li>
        </ol>
    </section>
    <?php 
    if($dataSet->GetLevel()==1)
    { echo "
        <section class='content'>
            <div class='row'>
                <div class='col-md-6'>

                            echo "

                                </div>
                            ";
                        }
                        echo "

        </section> "; 
    }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>

这是我在上一页中调用的类Telegram.class.php：

    <?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;
    }
}
?>

现在的问题是，每当我尝试提交表单时，都会收到以下错误消息：

未定义的索引：第10行的telegram_section.php中的键盘

以下是telegram_section.php的第10行：

$ key = $ _POST [＆＃39; keyboard＆＃39;];

获取此用户输入：

<label>
<input type='checkbox' name='keyboard' value='with_keyboard'>
Use dedicated keyboard for this bot
</label></br>
<label>
    <input type='checkbox' name='keyboard' value='without_keyboard'>
    Show keyboard at groups
</label></br>

所以如果你知道如何解决这个问题，请告诉我...提前谢谢！

Answer 1

该错误显示您在POST数组中没有该索引，为什么？，因为没有收到复选框，因为帖子中的“false”是这样的。试试这一行：

$ key =！empty（$ _ POST ['keyboard']）？ $ _POST ['keyboard']：'';

此外，不要“回显”所有表单，只需将其打印为普通HTML。

最后，如果您在输入之前没有显示任何错误标记，请检查您的“echo”，以防您将其标记为已选中。

PS：尝试使用observation<- hotel %>% + inner_join(dat, by = "word") %>% + count(Scoree)，以便在尝试调试脚本时检查阵列中的哪些索引。
