使用BACK按钮发出问题

标签： php

我是PHP编程的新手，因为我开始工作已经3天了，所以我需要你的帮助。 我正在创建一个包含4页的表单。当用户点击“返回”按钮时，例如从第2页到第1页，他之前在第1页上选择的所有数据都应该出现在那里，这样他就不需要再次填写。 能否通过发布代码来帮助我。

以下是示例代码

page1.php中

<?php
session_start();
$session=session_id();
$_SESSION['session']=$session;

    ?>
    <html>
    <body>
    <form action="oopssurvey.php" method="post">
    Where do you work?<br/>
    <Input type ="radio" name="location" value="USA" <?php if($_SESSION['location']    == 'USA') echo "checked='checked'" ?>/>In the United states<br/>
    <Input type ="radio" name="location" value="India" <?php if($_SESSION['location'] == 'India') echo "checked='checked'" ?>/>Outside of the United states<br/>

    <input name="Operation1" type="submit" value="saveandresume" />
    <input name="Operation2" type="submit" value="next" />

    </form>
    </body>
    </html>

使page2.php 

<?php
session_start();

if($_SESSION['session']==$session)
{
$location=$_SESSION['location'];
}
else
{
$_SESSION['location'] = $_POST['location'];
}
?>

<html>

<body>

<form action="oopssurvey.php" method="post">

<Input type ="radio" name="effective" value="Agree"/>Agree<br/>

page3.php

// // somecode

Survey.php 

<?php
session_start();
include 'classperson.php';


if($_POST['Operation1'])
{
$_SESSION['location'] = $location;
$_SESSION['location'] = $_POST['location'];
echo "Please save the link inorder to continue your survey http://bonnie/~jnagesh/SampleSurvey/OOPS/oopspage2.php";
}

else if($_POST['Operation2'])
{
$_SESSION['location'] = $location;
$_SESSION['location'] = $_POST['location'];
include "oopspage2.php";
}


elseif($_POST['Operation3'])

{
$_SESSION['effective'] = $effective;
$_SESSION['effective'] = $_POST['effective'];
$_SESSION['training'] = $training;
$_SESSION['training'] = $_POST['training'];
$_SESSION['treated'] = $treated;
$_SESSION['treated'] = $_POST['treated'];
$_SESSION['effort'] = $effort;
$_SESSION['effort'] = $_POST['effort'];
echo "Please save the link inorder to continue your survey later http://bonnie/~jnagesh/SampleSurvey/NextandBackButtons/page3.php";

}

elseif($_POST['Operation4'])
{

$_SESSION['effective'] = $_POST['effective'];
$_SESSION['training'] = $training;
$_SESSION['training'] = $_POST['training'];
$_SESSION['treated'] = $treated;
$_SESSION['treated'] = $_POST['treated'];
$_SESSION['effort'] = $effort;
$_SESSION['effort'] = $_POST['effort'];
include "oopspage3.php";
}

elseif($_POST['Operation5'])     /* THE PROBLEM LIES IN THIS CODE FOR BACK BUTTON*/
{
$location = $_POST['location'];
$_SESSION['location'] = $location;
<html> 
<body> 
<form action="1.php" method="post"> /*oBVIOUSLY i WONT BE ALLOWED TO DECLARE <HTML> INSIDE PHP*/
