How to Personalize User Experience with Session Variables
When a user has cookies disabled, or their ad blocker blocks cookies, your best to use session variables to ensure personalization works for them. This guide will show you how to use session variables
Parsley access to session variables should not be used on statically cached pages.
In this guide you will learn how to create page personalization, using session variables, on the Zesty platform. We will be modifying the loader file and a view file to create the most basic form of personalization.
There are three key components to executing personalization. The URL, the Session Variable, and the Business Logic. Let's start by looking at how to format the URL.
The URL
The url will contain the key to personalization, it is simply stored in a Get variable. A Get variable can be appended to the end of any URL. In our example, let's use st
, short for session test.
Note: when you setup links with advertisers, just append ?st=developer
or ?st=marketer
etc. and you can custom curate any experience you want to deliver.
Easy right? Now let's store that value to a session variable.
The Session Variable
Session variables are single references stored to memory on Zesty servers. Once a session variable is set, it can be accessed with Zesty's reference language, parsley. Parsley provides a simple way to set and access cookies, which looks like $_variable = 'hello world'
. Note the $_
denotes the variable a session variable, where are variable $
without the _
underscore is only available in a single page load.
In this example, we are going to store the Get variable passed by the URL to our session variable. To ensure we capture this on any page, we are going to put our code in the loader
view. From the Code Editor in your Satellite, open the loader
view file, and enter this line of code:
Open the loader view file and add:
Note: the name of the session variable doesn't effect the result, but the name cannot have spaces or abnormal characters. Session variables can also be overwritten, so on a page for marketers you could overwrite the variable to {{$_sesvar = 'marketers'}}
, and then start targeting your language to marketers.
The Business Logic
In our URL https://mydomain.com/page/?st=developer
we are passing the value developer
and capturing that value into our session variable. With an if
statement, we are going to check the session variable's value against our desired match developer
. If it's a match, we will show one type of content, otherwise we will show our default content. It's quick to implement, let's take a look at the code.
It's that easy, have fun!
