Hi,
I am new to php and am having problems with sessions, basically I have a form that I have split into 2 pages. I use session variables to collect the input from both pages and then output the values to a final page that will eventually email the submissions to me. This part works fine, I get all the desired information as required.
The problem I am having is that I am trying to make each page retain values as well as using session variables, so if a user decides to go back to make changes, they only have to change the desired field rather than having to re-enter values in all the fields.
When I try to go back, all the fields are empty.
I have tried using header instead of meta refresh and it still does the same thing. The only way I can get it to work is if I move
<?php
session_start();
$_SESSION['clientname'] = $_POST['name']; //name
$_SESSION['clientcompany'] = $_POST['company']; //company
?>
and
<?php
session_start();
$_SESSION['productname'] = $_POST['product']; //name
$_SESSION['sizename'] = $_POST['size']; //company
?>
from the top of the script to next block of php code. The the problem is that everything works but I have to reload the page before I get the session variables to populate.
here is the code :
<?php
session_start();
$_SESSION['clientname'] = $_POST['name']; //name
$_SESSION['clientcompany'] = $_POST['company']; //company
?>
<html>
<head>
<title>Page 1</title>
</head>
<body>
<?php
// move session stuff to here, works fine but reload of page needed.
$N = '';
$C = '';
if(isset($_POST['submit']))
{
//process the text-input field
if(isset($_POST['name']))
$N = $_POST['name'];
else
$N = false;
if(isset($_POST['submit']))
if(isset($_POST['submit']))
//process the text-input field
if(isset($_POST['company']))
$C = $_POST['company'];
else
$C = false;
//if all entries okay, process information, display message and exit script.
if ($N && $C)
{
echo '<META HTTP-EQUIV="Refresh" Content="0; URL=size.php">';
//exit;
echo '</body></html>';
exit();
}
}
echo '<h2>Page 1</h2>';
echo '<form name="Form1" action="' . $_SERVER['PHP_SELF'] . '" method="POST">';
//display text-input label for name
if(isset($_POST['submit']) && !$N)
echo '<p><font color="red" size="+1"><b>Please Specify</b></font><br />';
else
echo '<p>Please enter Name [required]<br />';
//display the text-input field
echo '<input type="text" name="name" maxlength="60" size="60"
value="' . $_SESSION['clientname'] . '" /></p>';
if(isset($_POST['submit']) && !$C)
echo '<p><font color="red" size="+1"><b>Please Specify</b></font><br />';
else
echo '<p>Please enter Company [required]<br />';
//display the text-input label for company
echo '<input type="text" name="company" maxlength="60" size="60"
value="' . $_SESSION['clientcompany'] . '" /></p>';
echo '<p><input type="submit" name="submit" value="submit"></p>';
echo '</form>';
echo '</body>';
echo '</html>';
and size.php
:
<?php
session_start();
$_SESSION['productname'] = $_POST['product']; //name
$_SESSION['sizename'] = $_POST['size']; //company
?>
<html>
<head>
<title>Page 2</title>
</head>
<body>
<?php
// move session stuff to here, works fine but reload of page needed.
$P = '';
$C = '';
if(isset($_POST['submit']))
{
//process the text-input field
if(isset($_POST['product']))
$P = $_POST['product'];
else
$P = false;
if(isset($_POST['submit']))
if(isset($_POST['submit']))
//process the text-input field
if(isset($_POST['size']))
$SI = $_POST['size'];
else
$SI = false;
//if all entries okay, process information, display message and exit script.
if ($P && $SI)
{
echo '<META HTTP-EQUIV="Refresh" Content="0; URL=success.php">';
//exit;
echo '</body></html>';
exit();
}
}
echo '<h2>Page 2</h2>';
echo '<form name="Form1" action="' . $_SERVER['PHP_SELF'] . '" method="POST">';
//display text-input label for name
if(isset($_POST['submit']) && !$P)
echo '<p><font color="red" size="+1"><b>Please Specify</b></font><br />';
else
echo '<p>Please enter Product Name [required]<br />';
//display the text-input field
echo '<input type="text" name="product" maxlength="60" size="60"
value="' . $_SESSION['productname'] . '" /></p>';
if(isset($_POST['submit']) && !$SI)
echo '<p><font color="red" size="+1"><b>Please Specify</b></font><br />';
else
echo '<p>Please enter Size [required]<br />';
//display the text-input label for company
echo '<input type="text" name="size" maxlength="60" size="60"
value="' . $_SESSION['sizename'] . '" /></p>';
echo '<p><input type="submit" name="submit" value="submit"></p>';
echo '</form>';
echo '</body>';
echo '</html>';
and success.php :
<?php
session_start();
echo 'product type is : ';
echo $_SESSION['productname'];
echo "<br>";
echo 'Client Name : ';
echo $_SESSION['clientname'];
echo "<br>";
echo 'Client Company : ';
echo $_SESSION['clientcompany'];
echo "<br>";
session_end();
?>
sorry about the size of the scripts, I have reduced them as much as I can. Any help would be greatly appreciated. Thank you.
