Multipage form

[jntcomputers]

I have a four page form and want to store the data in a session until it is submitted. I have this code at the top:
[code]
session_start();
$_SESSION['id'] = uniqid();
if (isset($_POST[$key])) {
        $_SESSION[$key] = $_POST[$key];
        echo "TESTING SESION SET!<br>";
}
print_r ($_SESSION);
print_r ($_POST);
[/code]

But this out puts:
Array( [id] => 444e9b5b2d41c [] => ) Array ( [B_FirstName] => test [B_MiddleInitial] => [B_LastName] => [B_SSAN] => [B_DateOfBirth] => [B_Email] => [B_HomePhone] => [B_CellPhone] => [B_WorkPhone] => [B_MaritalStatus] => ---- [B_YearsSchool] => [B_NumDependents] => [B_DependentAges] => [B_HomeAddress1] => [B_HomeAddress2] => [B_HomeCity] => [B_HomeState] => [B_HomeZip] => [B_YearsAtAddress1] => [B_MailingAddress1] => [B_MailingAddress2] => [B_MailingCity] => [B_MailingState] => [B_MailingZip] => [B_PrevAddress1] => [B_PrevAddress2] => [B_PrevCity] => [B_PrevState] => [B_PrevZip] => [B_YearsAtAddress2] => [coborrower] => Next Page --> )

As you can see the session variables from the form are blank, but the post variables are not. What am I doing wrong?!?

A simple method to force POST values into a session...

[code]<?php
if(!session_id()) session_start();

// makesure user got here using the form
if(!$_POST['Submit']){ // name of your submit button
    die ("You must have got here by mistake?");
}
// force post data to session for tracking

if(isset($_POST['Submit'])){ // name of your submit button
    foreach($_POST as $key => $value){
    $_SESSION['post_value'][$key] = $value;    
    }
}

echo "<pre>";
print_r($_SESSION);
echo "</pre>";
?>[/code]

$_SESSION['post_value'][$key] = $value;
[/quote]

Does this mean I have to enter the field value for every field.

I.E.
[code]
$_SESSION['name'][$key] = $value;
$_SESSION['email'][$key] = $value;
[/code]

And so on? Because there are liike 80 fields. Is there a way to do it dynamically?

[b]$key will be the name of the input from the form[/b]. It will loop thruogh all the post data

I used ['post_value'] to seperate data in the session.
You can remove it if you like, makes no difference
what I posted will take all the data and put in the session dynamicly.

the session would look like this
[code]array(

    [post_data] => array(
    
            [email] => test
            
            [name] => test
            
        )
)[/code]

Copy this to your server to see how it works if you like
[code]<?php
if(!session_id()) session_start();
$button_lable = "Next";
// force post data to session for tracking
if(isset($_POST['Submit'])){
    $button_lable = "Again?";
    foreach($_POST as $key => $value){
    $_SESSION['new'][$key] = $value;    
    }
    echo "<pre>";
    print_r($_SESSION);
    echo "</pre>";
}
?>
<form name="form1" method="post" action="<?php echo $_SERVER['PHP_SELF'] ?>">
  <p>
    <input name="name" type="text" id="name">
    name <br>
    <br>
    <input name="another field" type="text" id="another field">
  </p>
  <p>
    <input type="submit" name="Submit" value="<?php echo $button_lable ?>">
    <input name="hidden" type="hidden" value="foo">
  </p>
</form>[/code]
