防止ID 1被删除

-1

我有一个代码获取帐户的ID并删除它在数据库中，但我需要防止ID 1被删除。防止ID 1被删除

我该怎么做？

<?php 

    // connect to the database 
    include('dbconn.php'); 

    // confirm that the 'id' variable has been set 

    if (isset($_GET['admin_ID']) && is_numeric($_GET['admin_ID'])) 
    { 
    // get the 'id' variable from the URL 
    $id = $_GET['admin_ID']; 

    // delete record from database 
    if ($stmt = $con->prepare("DELETE FROM tbl_admin WHERE admin_ID = ? LIMIT 1")) 
    { 
    $stmt->bind_param("i",$id); 
    $stmt->execute(); 
    $stmt->close(); 
    } 
    else 
    { 
    echo "ERROR: could not prepare SQL statement."; 
    } 
    $con->close(); 

    // redirect user after delete is successful 
    header("Location: DeleteAdmin.php"); 
    } 
    else 
    // if the 'id' variable isn't set, redirect the user 
    { 
    header("Location: DeleteAdmin.php"); 
    } 

    ?>

检查'id'，如果没有操作删除查询。 –

'WHERE admin_ID <> 1' –

您在代码中使用if语句，因此不确定您需要了解更多信息。 – miken32

变化DELETE FROM tbl_admin WHERE admin_ID = ? LIMIT 1到DELETE FROM tbl_admin WHERE admin_ID = ? AND admin_ID != 1 的LIMIT 1是不必要假设你认为是主要的ID，因此存在不能有两个具有相同id。
