Question

我使用php作为服务器端脚本并使用表单在数据库中使用MySql插入数据。提交页面重定向到另一个页面并显示感谢等。但是当用户单击刷新按钮然后表单再次提交时，所以请告诉我如何阻止这一点。

我的第一页代码如下 -

<?php

$route=$_POST['route'];
$datee=$_POST['SelectedDate'];
$pick_time=$_POST['pick_time'];
$ampm=$_POST['ampm'];
$destination=$_POST['destination'];
$cab=$_POST['cab'];
$days="/";


?>

<html>
<head>



</head>
<body>
<form onSubmit="validateForm();" action="http://localhost/wordpress/?page_id=452"             method="post" name="localhire_select" >
<table>
<tr>
<td>
<div id="outer" name="outer" align="left" style="width:300px;height:300px;background-        color:#FAFA23;border:1px solid;padding:10px 30px;">
<table width="200" border="0" cellpadding="0" cellspacing="2">

<td  widtn="60%" align="left">Pick-up Date:</td><td><input type="text" name="datee"     size="10px"  value=<?php echo $datee ; ?> /></td>

第二页的代码是 -

<?php
error_reporting(E_ALL);
ini_set('display_errors', true);

$host="localhost";
$user_name="usr";
$pwd="pwd";
$database_name="db"; //assuming you created this
mysql_connect($host, $user_name, $pwd);
if (mysql_error()>"") print mysql_error() . "<br>";
mysql_select_db($database_name);
if (mysql_error() > "") print mysql_error() . "<br>";

$datee=$_POST['datee'];
$time=$_POST['time'];
$destination=$_POST['destination'];
$days=$_POST['days'];
$cab=$_POST['cab'];
$route=$_POST['route'];
$full_name=$_POST['full_name'];
$address=$_POST['address'];
$mobile_number=$_POST['mobile_number'];
$pickup_location=$_POST['pickup_location'];

 $query2="SELECT `order_number` FROM `count` WHERE 1";
 $count=mysql_query($query2);
while($row = mysql_fetch_array($count))
{
   $variable = $row["order_number"];
}


$query3="UPDATE `count` SET order_number=order_number+1 WHERE 1";
mysql_query($query3);


$query1="INSERT INTO `booking`         (`pickup_date`,`pickup_time`,`destination`,`days`,`type`,`full_name`,`address`,`mobile`,`pi    ckup_location`,`route`,`order_number`) VALUES     ('$datee','$time','$destination','$days','$cab','$full_name','$address','$mobile_number','$    pickup_location','$route','$variable')";
mysql_query($query1);

mysql_close();

?>

Answer 1

您正在寻找名为Post/Redirect/Get

的模式

基本上，在发布表单后，使用以下内容执行所有MySQL信息，然后重定向：

header('Location: thanks.php', true 303);

使用GET请求。然后，用户无法刷新该页面;它只会显示“谢谢”。

Answer 2

你需要在PHP中使用此SUBMIT按钮作为POST。试试这个!!!!

如果（isset（$ _ POST [ “提交”]））{ $日期= $ _ POST [ “日期”];

然后在INSERT QUERY之后使用HEADER。喜欢这个

echo header（“location：thank.php”）;

如何在刷新页面时停止重新提交页面？
