Question

我已经创建了一个用于注册的html表单，当用户成功注册时，我希望将它们自动重定向回我的index.html页面，并弹出警告告诉他们已经注册成功。目前我的警报有效，但它只是在空白页面中打开。我试过放入header ("location:../index.html")但是没有用，它只是指引我直接到页面而不给我想要的警报。任何人都可以帮忙吗？

<?php
$con = mysql_connect("localhost","root","") or die(mysql_error());
$select_db = mysql_select_db("mayan",$con);
if(isset($_POST['register']))
{
     $firstname=$_POST['first_name'];
     $lastname=$_POST['last_name'];
     $address=$_POST['address'];
     $postcode=$_POST['postcode'];
     $emailaddress=$_POST['emailaddress'];
     $password=$_POST['password'];
     $query = "select emailaddress FROM mayan_users where emailaddress='$emailaddress'";
     $link = mysql_query($query)or die(mysql_error());
     $num = mysql_num_rows($link);
 if ($num>0){
  echo 'Email already exists'; //email already taken
 }

 else {
 $insert_query = "insert into `mayan_users`(`firstname`,`lastname`,`address`,`postcode`,`emailaddress`,`password`) values('$firstname','$lastname','$address','$postcode','$emailaddress','$password')";
 $result = mysql_query($insert_query)or die(mysql_error());



  if(success)
{
   echo "<script type=\"text/javascript\">".
        "alert('success');".
        "</script>";
}
     }

   }
?>

我在网站填写表格后，使用此代码将某人重定向回主页。

if(empty($errors))
{
    //send the email

    echo '
        <script type="text/javascript">
            alert("YOUR MESSAGE"); 
            window.location.href = "http://www.yoursite.com";</script>';    
}

Answer 2

重定向时使用此功能：

function redirect($url) {
    if(!headers_sent()) {
        //If headers not sent yet... then do php redirect
        header('Location: '.$url);
        exit;
    } else {
        //If headers are sent... do javascript redirect... if javascript disabled, do html redirect.
        echo '<script type="text/javascript">';
        echo 'window.location.href="'.$url.'";';
        echo '</script>';
        echo '<noscript>';
        echo '<meta http-equiv="refresh" content="0;url='.$url.'" />';
        echo '</noscript>';
        exit;
    }
}

因此，您希望重定向到同一页面但使用？= XXX获取值

您的代码看起来像这样：

<?php

if ($_GET['success'] == 1){
        echo "<script type=\"text/javascript\">".
        "alert('success');".
        "</script>";
}
$con = mysql_connect("localhost","root","") or die(mysql_error());
$select_db = mysql_select_db("mayan",$con);
if(isset($_POST['register']))
{
     $firstname=$_POST['first_name'];
     $lastname=$_POST['last_name'];
     $address=$_POST['address'];
     $postcode=$_POST['postcode'];
     $emailaddress=$_POST['emailaddress'];
     $password=$_POST['password'];
     $query = "select emailaddress FROM mayan_users where emailaddress='$emailaddress'";
     $link = mysql_query($query)or die(mysql_error());
     $num = mysql_num_rows($link);
 if ($num>0){
  echo 'Email already exists'; //email already taken
 }

 else {
 $insert_query = "insert into `mayan_users`(`firstname`,`lastname`,`address`,`postcode`,`emailaddress`,`password`) values('$firstname','$lastname','$address','$postcode','$emailaddress','$password')";
 $result = mysql_query($insert_query)or die(mysql_error());



  if(success)
{
   redirect('index.php?sucess=1');
}
     }

   }
?>

要通过JavaScript重定向：

window.location = "http://www.google.com/";

但我建议添加一个供用户点击的链接，以及一些用户可能禁用了JavaScript。我会在重定向上设置超时，因此用户只需几秒钟即可阅读该页面。 E.g：

if (success) {
   echo "<script type=\"text/javascript\">" . 
         "setTimeOut(function() {" . 
         "   window.location = 'http://www.google.com';" . 
          "}, 2500);" .
         "</script>";
}

您可以在索引页面中执行变量，例如＆＃34; index.php？success＆＃34;。然后通过if（isset（$ _ GET [＆＃39; success＆＃39;]）检查此请求。并为该IF添加一些登录信息。

Answer 5

1）首先将 index.html 更改为php文件： index.php

2）在 index.php 文件的顶部写

<?php
    session_start();
?>

3）在 index.php 文件的正文中，您可以：

打印消息

<?php
   if(isset($_SESSION['message'])) {
     echo $_SESSION['message'];
     unset($_SESSION['message']);
   }
?>

或使用javascript提醒

<?php
   if(isset($_SESSION['message'])) {
     echo '<script> alert(\'Success\'); </script>';
     unset($_SESSION['message']);
   }
?>

4）在这个动作文件中，你给了我们

<?php

  // START THE SESSION
  session_start();

$con = mysql_connect("localhost","root","") or die(mysql_error());
$select_db = mysql_select_db("mayan",$con);
if(isset($_POST['register']))
{
     $firstname=$_POST['first_name'];
     $lastname=$_POST['last_name'];
     $address=$_POST['address'];
     $postcode=$_POST['postcode'];
     $emailaddress=$_POST['emailaddress'];
     $password=$_POST['password'];
     $query = "select emailaddress FROM mayan_users where emailaddress='$emailaddress'";
     $link = mysql_query($query)or die(mysql_error());
     $num = mysql_num_rows($link);
 if ($num>0){
  $_SESSION['message'] = 'Email already exists'; //email already taken
 }

 else {
 $insert_query = "insert into `mayan_users`(`firstname`,`lastname`,`address`,`postcode`,`emailaddress`,`password`) values('$firstname','$lastname','$address','$postcode','$emailaddress','$password')";
 $result = mysql_query($insert_query)or die(mysql_error());



  if($result)
  {
     $_SESSION['message'] = 'Success';
  }
 }

}
// redirect to main page
header("Location: /");
?>

重定向执行页面并弹出警报
