Include PDF with section title only on first page

Question

As suggested here, I'm using \includepdf to insert several multi-page PDF files of musical scores into a LaTeX document:

\newcommand{\insertScore}[3] {
  \addcontentsline{toc}{section}{#2}
  \includepdf[scale=0.8,pages=1,pagecommand=\section*{#2}]{#1/score.pdf}
  \includepdf[scale=0.8,pages=2-,pagecommand={}]{#1/score.pdf}

  … more stuff following
}

However, while most of these PDFs consist of two or more pages, some have only one single page, which makes the second \includepdf fail. Is there any way to work around this issue without knowing in advance, how many pages the included PDF will consist of? The LaTeX file is generated automatically in this project, therefore using different commands for different PDFs isn't really an option ...

Answer 1

Just test the number of pages in the PDF first (cf. this question).

\newcommand{\insertScore}[3] {%
  \pdfximage{#1/score.pdf}%
  \addcontentsline{toc}{section}{#2}%
  \includepdf[scale=0.8,pages=1,pagecommand=\section*{#2}]{#1/score.pdf}%
  \ifnum\pdflastximagepages>1\relax
    \includepdf[scale=0.8,pages=2-,pagecommand={}]{#1/score.pdf}%
  \fi
  %
  % … more stuff following
}
