PHP開(kāi)發(fā) 留言板教程之留言板刪除留言PHP頁(yè)面

刪除留言其實(shí)就是刪除我們數(shù)據(jù)庫(kù)里的數(shù)據(jù)

我們前面在刪除鏈接之前傳入了每條數(shù)據(jù)的 id?

<td><a?href="ressage_delete.php?id=<?php?echo?$row['id']?>"?>刪除</a>?</td>

所以在PHP頁(yè)面接收id，然后在刪除相關(guān)的id，就可以實(shí)現(xiàn)刪除的功能了

代碼如下

<?php
header("content-type:text/html;charset=utf-8");
$conn=mysqli_connect("localhost","root","root","ressage");
$id=$_GET['id'];
if($conn){
    $sql="delete from ressage_user where id ='$id' ";
    $que=mysqli_query($conn,$sql);
    if($que){
        echo"<script>alert('刪除成功，返回首頁(yè)');location.href='ressage.php';</script>";
    }else{
        echo "<script>alert('刪除失敗');location='" . $_SERVER['HTTP_REFERER'] . "'</script>";
        exit;
    }
}die("數(shù)據(jù)庫(kù)連接失敗" .mysqli_connect_error());
?>


繼續(xù)學(xué)習(xí)

<?php header("content-type:text/html;charset=utf-8"); $conn=mysqli_connect("localhost","root","root","ressage"); $id=$_GET['id']; if($conn){ $sql="delete from ressage_user where id ='$id' "; $que=mysqli_query($conn,$sql); if($que){ echo"<script>alert('刪除成功，返回首頁(yè)');location.href='ressage.php';</script>"; }else{ echo "<script>alert('刪除失敗');location='" . $_SERVER['HTTP_REFERER'] .
