Question

我有按钮，onclick我得到这样的链接：//..../ update_news.php？newsID = 112＆amp;＆amp; value = delete

使用此代码：

'<td style="width:50px;"> <u> <b><a href="update_news.php?newsID='.$row['newsID'].'&&'.'value=delete'.'">'.'<img src="src/img/delete.png" /></b></u></td></a>';

然后我尝试使用此类删除行，但它不起作用：

class Delete{
    private $db;
    public function __construct(){

        $this->db = new Connection();
        $this->db = $this->db->dbConnect();
        }
        public function Delete($title, $date, $short_description, $description){

        $newsID = $_Get['newsID'];
        $delete = $_Get['delete'];

        if(isset($delete))
        {
            $sql = "DELETE FROM `News` WHERE  newsID= :newsID";
            $stmt = $pdo->prepare($sql);
            $stmt->bindParam(':newsID', $_GET['newsID'], PDO::PARAM_INT);   
            $stmt->execute();
            echo "WORKS";

        }
        else
        {
            echo "Papapapapa";
        }

}}

我称这个班：

$object = new Delete();
$object->news($newsID, $title, $date, $short_description, $description);

谢谢有人会帮助我。

在我看来，你应该做的第一件事就是重命名你的Delete函数，使它没有大写，所以你不会把它与你的班级混淆。

我要尝试的第二件事实际上是调用（很快将被重命名）delete函数，因为现在你正在调用一个名为news的函数，这可能是一个错字或代码我们可以'看。请尝试使用$object->delete(...)代替$object->news(...)。

为什么要调用news（）方法？您将方法写入构造函数。你必须写成这样一个类：

class Delete{
    private $db;
    public function __construct(){

        $this->db = new Connection();
        $this->db = $this->db->dbConnect();
    }
    public function DeleteNews($title, $date, $short_description, $description){

        $newsID = $_Get['newsID'];
        $delete = $_Get['delete'];

        if(isset($delete))
        {
            $sql = "DELETE FROM `News` WHERE  newsID= :newsID";
            $stmt = $pdo->prepare($sql);
            $stmt->bindParam(':newsID', $_GET['newsID'], PDO::PARAM_INT);
            $stmt->execute();
            echo "WORKS";

        }
        else
        {
            echo "Papapapapa";
        }

    }
}

之后调用DeleteNews方法。

$object = new Delete();
$object->DeleteNews($title, $date, $short_description, $description);

删除db中的行
