Passing session varaible through url

I decided to simplify things.

session_start();
if(!isset($_SESSION['current_step'])) 
$_SESSION['current_step'] = 1;
else if(isset($_SESSION['current_step']) == 1)
$_SESSION['current_step'] = 2;
else if(isset($_SESSION['current_step']) == 2)
$_SESSION['current_step'] = 3;
else if(isset($_SESSION['current_step']) == 3)
$_SESSION['current_step'] = 4;
else
$_SESSION['current_step'] = 1;


Header('Location: http://www.devwebsites.com/forums/install/index.php?$_SESSION[\'current_step\']');
?>

 

and when i click the next button i get this in my url bar.

 

http://www.devwebsites.com/forums/install/index.php?$_SESSION[%27current_step%27]

 

how do i fix this? i thought i was doin this right..

Why would you want to pass a session variable through the url? You can retrieve the value on the next page regardless, thats the entire point of sessions.

 

Anyway.... variables are not interpolcated within single quotes.

 

Header('Location: http://www.devwebsites.com/forums/install/index.php?sess=' . $_SESSION['current_step']);

Well I posted in another thhread about this. I believe its still on the first page. anyway this is for forum installation and each time they click the next button i want to add one to the variable step which would display the next echo in the case switch.  View the other thread from the start for more information about this.

Do you understand what sessions are?

[BoltZ]

Sort of. But I am having trouble with my code. I am trying to get it when the person clicks the button it will be like

index.php?step=2

 

then 3 and then 4 and then all the way to 9 where i finish setup. But I don't want the user to be able to just manually type in the steps without something being set. Here is my code so far. I click on next and it goes to step 2 then it keeps going to step 2.

session_start();
if(!isset($_SESSION['current_step'])) $_SESSION['current_step'] = 1;

//lets check to see if step in in the url using isset. If it isnt, default step to one
$step = isset($_GET['step']) ? $_GET['step'] : 1;

if($step <= $_SESSION['current_step']){
    
    switch($step){
        case 1:
        $_SESSION['current_step'] == 2; ?>
//bunch of code i edited
        <form action="install.php" method="post">

<div>
<input type="image" src="images/next_button.gif" alt="Submit button" value="Next" name="step1" />
</div>
</form>
//end of code i edited
<?php
        break;

        case 2:
        $next_page = 3;
        ?>
<form action="install.php" method="post">
<div>
<input type="image" src="images/next_button.gif" alt="Submit button" value="Next" name="step1" /></div>
</form
<?php
        break;

        case 3:
        $next_page = 4;
        ?>
<form action="install.php" method="post">

<div><input type="image" src="images/next_button.gif" alt="Submit button" value="Next" name="step1" /></div>
</form><?php
        break;

        case 4:
        $next_page = 5;
        include 'step4.php';
        break;
    }
    
}

?>

<?php
//step 1.php
//your process logic, saving data etc.
$errors = false; //chage this if the user does not pass your step 1 requirements


if(!$errors){
    //rewrite the session current step var
    $next_step = 2;

    if($_SESSION['current_step'] < $next_step) $_SESSION['current_step'] = $next_step;

    //your link should look like index.php?step={$next_step}
}

?>

 

A url for this is in my signature

 

and it goes to install.php which is this

session_start();
if(!isset($_SESSION['current_step'])) 
$_SESSION['current_step'] = 1;
else if(isset($_SESSION['current_step']) == 1)
$_SESSION['current_step'] = 2;
else if(isset($_SESSION['current_step']) == 2)
$_SESSION['current_step'] = 3;




Header('Location: index.php?step=' . $_SESSION['current_step']);
?>

 

Sorry if its alot. Feel free to edit this post to delete everything thats not necessary

Session variables do not need to be passed through the URL.

 

The following code does something similar to what you described:

<?php
session_start();
if (isset($_GET['clr']) && isset($_SESSION['step'])) unset ($_SESSION['current_step']);
if (!isset($_SESSION['current_step'])) $_SESSION['current_step'] = 1;
switch (true) {
case ($_SESSION['current_step'] > 0 && $_SESSION['current_step'] < 10):
	echo '<h1>Step ' . $_SESSION['current_step'] . '</h1>';
	break;
default:
	echo 'oops ... ' . $_SESSION['current_step'];
	$_SESSION['current_step'] = 0;
}
$_SESSION['current_step']++;
echo '<br><a href="?x">Go to step ' . $_SESSION['current_step'] . '</a>';
?>

Is this all for one file? Or is this the install.php page which is the action for the form...i am very confused

[kenrbnsn]

My example is one file. You can put the form in the same file as the action.

 

Ken

[BoltZ]

Can you show me an example of how to do that? sorry but im not the greatest back-end developer in the world..

 

like do i need a form action?

 

and do i even need the install.php file?
