Hello saldit,
you have the tutorial below which are speaking about those plugin.
For "CSS" and "JS" => simply add your code.
For the 3 others, it's simply to add some custom PHP code.
You have acces to the variables :
- $fields => array of each field in the view
- $config => array of differents variables of the process
- pk : the id of the content
- storages : value stored in the database (only for store process)
- ...
Just make a dump on both variables to see which properties you can access.
Best regards.
Lionel
