Simple session variable question.

Hi,

Coding isn't my strong point as you can probably guess from this question!

I am revamping a site and have decided to use MODX to make future maintenance easier. The problem I have been stuck on all day is regarding the capture of a variable from the url.

The user lands on our page with or without an affiliate tracking paramater appended to the url: -

eg. www.mydomain.co.uk/?int=123

This variable then needs to be stored in a session so that if the user moves around the site the tracking code stays with them and if required added to a link that sends them to our quote engine: -

eg http://quote.mydomain.co.uk/index.php?int=123

I have this working on our existing site by simply using the following script: -

<?
session_start();

// store session data
$_SESSION['int']=$int;

if ($int == '')
{
$int='0000';
}

?>

And then to redirect the user: -

header('Location: http://quote.mydomain.co.uk/index.php?int='.$int);

For some reason I can't get it to store the variable within modx. I have read that you don't need to use session_start in modx and have tried other avenues but keep going round in circles!

I would appreciate any help!!

Thanks

The session is already started as soon as MODx gets the page request. Either a plugin or a snippet at the top of your template would do the trick. Fetch the value from the $_GET, validate it, and load it into the $_SESSION. Keep in mind that all $_GET and $_POST values are strings, not numbers. Something like this:

Then your link would be

Thanks Susan, I appreciate the help.

I'm still having problems passing a value through. I'm developing/testing locally at the moment....would that have any impact?

I have a snippet GetIntCode at the top of my template and call it by [[GetIntCode]]

This snippet looks like this as advised: -



Then I simply use another snippet quoteonline to redirect: -



When I test by going to localhost/mydomain/index.html?int=100 the int variable holds 0000.

At the risk of sounding dumb any ideas?

Many thanks again.

That last redirect url should be: -

header('Location: http://quote.mydomain.co.uk/index.php?int='.$_SESSION['int']);

Think the forum editor added some stuff!
