Using a variable as a package setting within a class

Question

I have defined a new class. Within this class, I am calling on the hyperref package, and I set the following options:

\RequirePackage{hyperref}
\hypersetup 
{
  pdfauthor={...},
  pdfsubject={...},
  pdftitle={...},
}

Now, I have defined certain variables within this class (which I can call with \variablename{}). However, if I use these within this package, as part of the option settings, then this fails (undefined control sequence). Am I not using the right syntax?

\RequirePackage{hyperref}
\hypersetup 
{
  pdfauthor={\variablename{}},
  pdfsubject={\variablename{}},
  pdftitle={\variablename{}},
}

I've read these questions (variable-name \newcommand with parameters within another \newcommand and Defining a newcommand, with variable name, inside another newcommand), but they are about newcommands... this is rather a regular package (hyperref) that I'm including, so I'm hoping it does not need to be this complicated)...

Answer 1

The following combination correctly sets the pdfauthor to "Andrew":

test.sty:

\newcommand{\myname}{Andrew}

\RequirePackage{hyperref}

\hypersetup{pdfauthor={\myname}}

main.tex:

\documentclass{article}

\usepackage{test}

\begin{document}
Text.
\end{document}

It is important not to call the \hypersetup command before the variable \myname has been set. However, it could be put in an \AtBeginDocument command to delay processing to the that point.
