从phpadmin删除记录

Question

我有一个带有相应删除按钮的行列表。当用户单击删除按钮时，必须删除该行。

我的html按钮作为表格的一部分。我检查了是否将正确的ID传递给了函数。

 <td style="border-color: #f3e0d7" ><button  name="btn_delete" class="deleteSub" onclick="DeleteSubscription('.$row["RSS_ID"].')" >Delete</button></td>         

javascript的DeleteSubscription按钮

function DeleteSubscription(id){

alert(id);

if(confirm("Are you sure you want to remove this subscription?")){
    $.ajax({
        url:'LandingPage.php',
        method:"POST",
        date:
            {
                delete_Subscription:1,
                idPHP:id,
            },
        success:function(response){
            alert(response);
            fetch_data();
        },
        dataType:"text",
    });
}
};

我的用于与表通信的PHP代码

if(isset($_POST['delete_Subscription'])){

$ID = !empty($_POST['idPHP']) ? trim($_POST['idPHP']) : null;

try{
    $connect = mysqli_connect($servername,$username,$password,$database);

    $sql=("DELETE FROM rssfeeds WHERE RSS_ID='".$ID."'");

    if(mysqli_query($connect,$sql)){
        exit('Subscription deleted');
    }
    else{
        print_r($sql->errorInfo());
        exit('error');
    }
}catch(PDOException $e){
    console.log($e);
}
}
