Question

我正在尝试创建一个删除链接，当我点击它时会删除带有给定ID的sql表中的一行，它应该是这样的，但它不起作用，请你看一下我的代码并告诉我，我做错了什么，谢谢！

这就是链接，当我点击存档它应该删除该行。

这是archivenews.php

echo '<td><a href="archivenews.php?newsid='. $row['ID'] .'">Arhiviraj</a>/<a href="archivenews.php?newsid='. $row['ID'] .'">Obrisi</a></td>';

先谢谢你了！

在'header（“Location：oglasi.php”）之前添加; ' -

mysql_query($query);

您需要对数据库执行查询，mysql_query（）会执行此操作。

所以，你的代码变成了 -

<?php
session_start();
require('konektor.php');

if(!(isset($_SESSION["login"]) && $_SESSION["login"] == "OK")) 
{
    header("Location: index.php");
    exit;
}
else
{
    $id = $_GET['newsid'];
    $query = "DELETE FROM `Oglasi` WHERE `ID` = '$id'";
    mysql_query($query);
    header("Location: oglasi.php");
}
?>

只是检查查询是否已在那里执行，您也可以执行此操作 -

    <?php
session_start();
require('konektor.php');

if(!(isset($_SESSION["login"]) && $_SESSION["login"] == "OK")) 
{
    header("Location: index.php");
    exit;
}
else
{
    $id = $_GET['newsid'];
    $query = "DELETE FROM `Oglasi` WHERE `ID` = '$id'";
    $result = mysql_query($query);
    if(!$result) 
    {
        die("Could not archive" . mysql_error());
        //This will display any error in the execution of query.
    } 
    header("Location: oglasi.php");
}
?>

从表中删除一行
