General ⇒ Current chapter number variable

[ProbablyNotYou]

Hello,

I'm searching for a way to automatically set labels depending on in which chapter the labeled item is in. Something like a variable that contains the current chapter number, is what I'm looking for. I want to use a selfmade section, that is automatically labeled, so that I can reference it by:[chapternumber . sectionnumber] (In which the sectionnumber is the by me given number). It should look something like this, if \currentchapter contained the current chapter number:

Code: Select all

Code, edit and compile here:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
\documentclass[11pt,titlepage,a4]{report}
\usepackage{hyperref}
\newcommand{\ownsection}[1]{\section{Definition #1}\label{\currentchapter.#1}}
\begin{document}
\chapter{Exponential Equations}
\ownsection{1}
something
\chapter{Next}
Exponential Equations are defined as in \hyperref[1.1]{Definition 1}.
\end{document}

Run LaTeX here

In PDF I want it to look like:

Chapter 1
Exponential Equations

Definition 1
something


Chapter 2
Next

Exponential Equations are defined as in Definition 1.

I'm looking forward to any help .
Thanks a lot!

Welcome to the forum!

You can use \thechapter:

Code: Select all

1
\newcommand{\ownsection}[1]{\section{Definition #1}\label{\thechapter.#1}}
