我想在dashboard-home.php中显示数据库中的总记录。

  

我收到未定义索引的错误

如何正确链接到页面以获取同一页面中的内容我指的是同一div中的不同页面。

<!DOCTYPE html>

请注意,您的网址为 dashboard.php ,没有dashboard.php?dash-home=1的查询字符串,这意味着此条件不起作用,您将获得未定义的索引通知你得到了:

if($_GET['dash-home']){

如果您检查代码,则表示您已使用isset()进行其他输入,因此您还需要在此处添加isset()

if(isset($_GET['dash-home'])){

根据您的信息中心链接:

<a href="dashboard.php?dash-home"><h2>DASHBOARD</h2></a>

您无法从dash-home获取值,因为您没有使用dash-home的值,您可以使用:

<a href="dashboard.php?dash-home=1"><h2>DASHBOARD</h2></a>

还有一点,$_SESSION在顶层需要session_start(),而我在您的文件中找不到此功能。这只是旁注,你需要注意这一点。

<强>更新 如果要显示默认包含的文件而不是需要使用其他部分,根据您的注释,您需要根据条件使用一个包含文件,请尝试:

<?php 
if(isset($_GET['dash-home'])){
    include 'dashboard-home.php';
}
elseif(isset($_GET['gallery'])){
    include 'pages/gallery_panel.php';
}
elseif(isset($_GET['news'])){
    include 'news_panel.php';
}
elseif(isset($_GET['view_news'])){
    include 'view_news.php';
}
elseif(isset($_GET['edit_news'])){
    include 'edit_news.php';
}
else{
    include 'dashboard-home.php';
}
?>

  1. 我建议使用switch而不是if-else

  2. 您正在查看$ _GET [&#39; dash-home&#39;]但您需要查看$ _GET [&#39;页面&#39;]

  3. 尝试:

    if(isset($_GET['page']))
        {
            switch ($_GET['page'])
            {
                case 'dash-home':
                    include 'dashboard-home.php';
                    break;
                case 'gallery':
                    include 'pages/gallery_panel.php';
                    break;
    
                and so on.....
            }
        }
