I am working on a multipage form, where users proceed saving data form page to page. Here is an idea of the flow:
PAGE 1
<form action="page2.php" method="POST">
input data_page1
</form>
PAGE 2
<?php
session_start();
session_register('data_page1');
$_SESSION['data_page1'] = $_POST['data_page1'];
?>
<form action="page3.php" method="POST">
input data_page2
</form>
PAGE 3
<?php
session_start();
session_register('data_page2');
$_SESSION['data_page2'] = $_POST['data_page2'];
?>
if (!$_SESSION['data_page2']){
echo "Go back to ".'<a href="page2.php">'."page 2".'</a>';
}
else{
<form action="page4.php" method="POST">
input data page3
</form>
}
Everything works fine if users input data correctly.
If at page 3 they they forget to input something, they are redirected back to page 2. The problem is that when they are redirected there, the data previously stored from page 1 are lost.
Are sessions the problem here?
its give you an idea how to handle
session_start();
if(!isset($_SESSION['data_page1']))
{
session_register('data_page1');
$_SESSION['data_page1'] = $_POST['data_page1'];
}
else
{
//user moving back
//how you want handle it write here
}
