How can I add custom PHP code below the the permalink field in Admin Dashboard post edit page?

[ad_1]

I’ve been trying to figure this out but the nomenclature isn’t that intuitive. What I mean is when I google for “**how to edit the admin area**” or “**how to customize the admin dashboard**” most of the results are having to do with using a white label plugin, but ***I’m trying to do this with code*** (lol, yes usually I’m asking for a plugin, but this time I thought it’d be pretty simple to code it myself)

So, it should look like:

Permalink:
ID Link:

​

[Admin Dashboard post editor content area showing where I want to add the permalink])

I don’t know if this is metabox related or not, but it might be

## What I’ve Tried Already:

I found [\[this old WEBFX\]]) post and surprisingly, all of the code snippets still work! Unfortunately, it is mostly about removing things and nothing that applies directly to my task

Somehow I got ahold of the idea that maybe I’m trying to add a metabox, and found [\[this Smashing Magazine post from 2011\]]). It seems like overkill for what I’m trying to do

I continued to follow the metabox route — mind you, I looked at the WordPress codex and it is lacking in multiple examples of use cases for functions like unregister\_widget, remove\_meta\_box, etc.
