Question

你好我用php mysqli程序语言制作Crud应用程序。我能够检索和插入数据但无法删除。当我点击删除链接时，它会进入delete.php页面，但没有任何反应。 db.php中

<?php
$conn = mysqli_connect('localhost', 'root','123','app');

?>

的index.php

    $result = mysqli_query($conn,$query);
    while($row = mysqli_fetch_assoc($result)){

        </div>

</body>

</html>

delete.php

<?php

include 'db.php';
if (isset($_GET('id'))) {
    $delete_id = $_GET['id'];
    $query = "delete from people where id = '$delete_id'";
    $run = mysqli_query($conn,$query);
    if ($run) {
        header("Location:index.php");
    }
}

?>

Answer 1

第4行的delete.php中有拼写错误。

在GET数组中，您必须在键名称周围使用[]括号而不是()

if (isset($_GET['id'])) {...}

无法使用php从网站删除一行
