Question

我希望在成功删除字段时显示成功消息。

我已经有一个确认警报正在运行，但现在我想回复一条消息（或用js显示它）查询成功了。

当我尝试if部分时，它总是显示post verwijdert（在荷兰语中删除的帖子），但我希望它在确认提醒后显示。

    <script language="JavaScript" type="text/javascript">
            function delpage(id, title)
            {
               if (confirm("Weet je zeker dat je '" + title + "' wilt verwijderen?"))
               {
                  window.location.href = '?delpage=' + id;
               }
            }
        </script>
        </header>

<div id="verwijder">

        <?php

    $blogPosts = GetBlogPosts();

foreach ($blogPosts as $post)

}  

//run if a page deletion has been requested
if(isset($_GET['delpage'])){

    $delpage = $_GET['delpage'];
    $delpage = mysql_real_escape_string($delpage);
    $sql1 = mysql_query("DELETE FROM blog_posts WHERE id = '$delpage'");
    header('Location:verwijder.php');
    exit();
}




$sql = mysql_query("SELECT * FROM blog_posts ORDER BY id DESC");
while($row = mysql_fetch_object($sql)) 
{
        echo "<tr>";
        echo "<h1><td>$row->title</td></h1>";
        if($row->id == 0)
        { //home page verberg delete link
        } 
        else 
        {
            // delete functie waarbij een alert word weergegeven of je dit zeker wil
            echo "<td><a class='link' href=\"javascript:delpage('$row->id','$row->title');\">Verwijder</a></td>";
        }
        echo "</tr>";
}

if ($sql1 == !false)
{
    echo '<h1>Post verwijdert</h1>';
}
else
{
    echo 'test';    
}
?>

</div>

您可以在$_SESSION中保留删除结果并执行以下操作。但在使用sessiony之前，请务必执行session_start();

//run if a page deletion has been requested
if(isset($_GET['delpage'])){
    $delpage = $_GET['delpage'];
    $delpage = mysql_real_escape_string($delpage);
    $sql1    = mysql_query("DELETE FROM blog_posts WHERE id = '$delpage'");
    if($sql1)
      $_SESSION['delete'] = 1;
    header('Location:verwijder.php');
    exit();
}

然后在verwijder.php

if(isset($_SESSION['delete']) && $_SESSION['delete']){
   //Show success message of delete here
   unset($_SESSION['delete']);
}

删除后显示成功消息（查询成功）
