I was answering a user question and it turned out more informative than planned, so I have made it a doc as I have seen many people including myself initially confused by it. This is one that has caught us all at one time or another.
The Set Session step in Wappler should not have an output option at all, it is an oversight they just have not got around to fixing yet.
- There are 2 different types of sessions, client side and server side, server side sessions are what Server Connect uses and are stored in a file on your server.
- Many server side languages store this file in a /tmp directory on your server.
- The file name of this can be found in your Chrome developer tools
- In PHP they are stored in another directory, and if you place a file called
/public_html/folder with the following content
<?php phpinfo(); ?>and call the file in your web browser you will be able to find the path to the file.
- If you want to view the contents of the file and have root access to your server via ssh or a WHM terminal you can do so by entering
nano /var/cpanel/php/sessions/ea-php72/sess_2cd33fa78d820abdc74c47a553f5eb91replacing my path with your own and my filename with your own. Hit enter and it should show something like this which confirms the session is saved.
Alternatively you could also run this at the very top of your client side webpage to see the contents.
<?php // Start the session session_start(); // Show session variables print_r($_SESSION); ?>
Correct usage of Server Connect server side sessions
Set a session to be used in other server actions
- Add a
Core Actions > Set Sessionstep
- Give the session a name like
- Give the session a value of whatever, example
If you want to view the contents of this session in a DIFFERENT server action
- Right click
Globals > $_SESSIONclick
- Name the variable the same as what you set
To Set and View or use the Session in the same Server Action you need a combination of both and obviously you can not try use the session variable before it has been set, so make sure your set session is first. Something like this.
Your output will now show something like
As you can see there is no output for
sesstestingnew which is the Set Session command however the output is now available for use which I show in the
myval2 Set Value step.
