This is about the question How can I add custom data to a post? a small tutorial
How to add custom data permanently to a post It will be saved into the object:You need the following hook:
{ "hook": "filter:post.create", "method": "postCreate" }This hook is fired, when a Post is created. So it contains RAW Data.
A filter:hook like "hook": "filter:post.create" can be edited before beeing proceeded.
plugin.postCreate = function(data, callback){ // Edit data here callback(null, data); }You can access all Data you can work with via the data object.
All those filter-hooks needs callbacks. The callback contains the modified / added / removed data.
Whats inside the data object?The data object contains two main objects.
this.post this.data post: { pid: 259, uid: 2, tid: 111, content: '### This is just a little snippet.', timestamp: 1617150411838 }, data: { uuid: '7277s31-6d23-43sa-1284-ad27e42yx879', title: 'How to add custom data to post serverside - in a nutshell', content: '### This is just a little snippet.', thumb: '', cid: '2', tags: [], uid: 2, req: { [...] }, timestamp: 1617150411838, fromQueue: false, tid: 111, ip: '111.123.2123.21', isMain: true } }With all the data you can work with. But only this.post is directly effected (lol) to the post Object.
If you add data here. It will be attached to the post forever and you can access it any time. Even after plugin disable.
So now add custom data:
plugin.postCreate = function(data, callback){ // adds data **PERMANENT** to post // before any other procession -> RAW DATA (markdown) //data.post.myData = "directly effected to post you can work with it in next step"; //data.data.myData = "other data for other things I don't know"; var myData = {}; myData.name = "Schmock"; myData.signature = "raz0rn"; // Stick myData to post object data.post.myData = myData; // Debug? // console.log("POST CREATE", data); // finish the process() - passes on modified data callback(null, data); }So myData has added to post:
post: { pid: 259, uid: 2, tid: 111, content: '### This is just a little snippet.', timestamp: 1617150411838, myData: { name = "Schmock", signature = "raz0rn", } }The data is stored. Everybody is happy.

How to add dynamic data before render a post in template It wont be saved to the object. You can use this for dynamic things or logic before rendering the page.:You need the following hook:
{ "hook": "filter:topics.addPostData", "method": "addPostData" }This hook is fired before engine renders the template.
It also needs a callback because its a filter-hook.
Same thing as above. Only the hook is different. And the data we are changing is temporarily.
Data contains all data we can use for the dynamicness lol: .
Now you can work with posts like a boss.
