Inserting additional template data into composer template

erichbb

Hi, I am customizing the default composer.

To have a better understanding of how this templating system works, I am trying to add a new variable, similar to isTopicOrMain for a conditonal in the composer.tpl.

I noticed that isTopicOrMain is defined in 2 files

library.js, in line:197, inside object templateData
composer.js in line:457, inside object data

when are each definition used?
From the look it seems one is for server side and the other one is client side? Are the two object synchronized at some point then?

Thank you.

Yes one is server side and one is client side.

@erichbb I think this might help you:

howto: inject hidden data into composer?

@yariplus Nice! I will explore other features first while waiting for the merge and release. Yes, got your point that "anything on the client is modifiable" :).

Of course your fields don't need to be hidden. But with this example and editing composer you should be able to add fields to composer as default. Hidden as well as visible.

@pitaj
when does that server side code (filterComposerBuild method) runs?

Specifically, I know it is binded to the hook filter:composer.build method I do not know when does that hook fires.
I have put some console.log() statements inside the filterComposerBuild method, but I can't find the output from either brower's debug console or nodebb backend terminal (running in ./node dev).
And from the name of the method, it seems it is only executed once when the composer initializing?

Which hook should I bind to if I want react to interaction? (Or are hooks only relevant for server side stuff?)

Thanks.

@dogs Thanks.
Can you point me to some materials explaining how the frontend and hooks interact?
I don't complete follows their discussion on data.submittedData and is still confused about which variable is the post data stored in and which hooks are involved when it is passed around.

Edit:
Also found this, maybe relevant
