Question

我想在php中显示一个javascript警告框并导航回主页面。这是我的代码

    session_start();
    $name= $_SESSION['name'];
             $id= $_SESSION['id'];
            //check if is a guest 
            if($name=="Guest"){
        echo'<script type="text/javascript">alert(" You are not allowed to view this contnent"); </script>';
        header('Location: mainPage.php');
    }
    //the rest of my page

使用此代码，警报弹出窗口不会仅显示重定向。我也试试这个

$name= $_SESSION['name'];
    $id= $_SESSION['id'];
    //check if is a guest 
    if($name=="Guest"){

        echo'<script type="text/javascript">window.alert(" You are not allowed to view this contnent");</script>';
        echo'<script type="text/javascript> window.navigate("mainPage.php"); </script>';

    }
            //the rest of my page

现在显示弹出窗口，但重定向不起作用。

Answer 1

试试这个。只需在页面需要重定向的秒数后添加。所以

更改

header('Location: mainPage.php');

到

header( "refresh:5; url=mainPage.php" );

Answer 2

$name= $_SESSION['name'];
    $id= $_SESSION['id'];
    //check if is a guest 
    if($name=="Guest"){

        echo'<script type="text/javascript">window.alert(" You are not allowed to view this contnent");</script>';
        echo'<script type="text/javascript> window.location.href="mainPage.php"; </script>';

    }

请查看此代码

Answer 3

session_start();
$name = $_SESSION['name'];
$id = $_SESSION['id'];
//check if is a guest 
if($name=="Guest"){
    echo'<script type="text/javascript">
           alert(" You are not allowed to view this contnent");  
           self.location="mainPage.php"; 
         </script>';

}
