Title page and Abstract link to the same page?

Question

I am writing a thesis and I would like to put the title page and abstract into the table of contents. However, my title page hyperlink and abstract hyperlink both link to the title page.

Here is my main Latex file:

% main.tex================================================================

%preamble
\documentclass{my_thesis}

% preamble contains title page, signature page, acknowledgment and abstract texts
\usepackage{import}


% Pacakges used
\usepackage[utf8]{inputenc} % Remove warning on ascii conversion
\usepackage[T1]{fontenc} % Remove warning on ascii conversion
\usepackage[margin=1in,letterpaper]{geometry} % decreases margins
\usepackage{float}  % for figure "H"
\usepackage{amsmath}    % math
\usepackage{hyperref} % hyperlinks
\setlength{\parskip}{0.5em} % paragraph spacing
\usepackage{graphicx}   % figure
\usepackage{subfig}
\usepackage[nottoc]{tocbibind}  % put bib in the table of content 
\usepackage{amsfonts} % for math equations
\usepackage{array} % table
\newcolumntype{M}[1]{>{\centering\arraybackslash}m{#1}}
\usepackage{listings}   % code

\newcommand{\myparagraph}[1]{\paragraph{#1}\mbox{}\\} % paragraph with line break

\begin{document}

    % title page-------------------------------------------
    \input{./Chapter_title/title_page.tex}
    \addcontentsline{toc}{chapter}{Title Page}
    % ----------------------------------------------------

    % abstract -------------------------------------------
    \input{./Chapter_abstract/abstract.tex}
    \addcontentsline{toc}{chapter}{Abstract}
    % ----------------------------------------------------

    % acknowledgement ----------------------------------------
    \input{./Chapter_acknowledgement/acknowledgement.tex}
    \addcontentsline{toc}{chapter}{Acknowledgement}
    % ----------------------------------------------------

    % generate table of contents ============================
    \setcounter{tocdepth}{5}    % set the depth of table of contents
    \tableofcontents
    % ======================================================

    \input{./Chapter_introduction/introduction.tex}

    ...

\end{document}

My title page file:

% title_page.tex================================================
\thispagestyle{empty}
\begin{titlepage}
    \begin{center}
        \vspace*{1cm} 
        
        { \huge
            \textbf{My Ttile}
        }

        ...
                
    \end{center}
\end{titlepage}

My abstract page file:

% abstract.tex=================================================
\thispagestyle{plain} 

\begin{center}
    \vspace*{1cm} 
    
    { \Large
        \textbf{My Title}
    }
    \vspace{0.4cm}
    \large

    by \\
    \vspace{0.4cm}
    \textbf{XXX}
    
    \vspace{0.9cm}
    \textbf{Abstract}
    
\end{center}

 My abstract...

By doing so, I am able to see Title Page and Abstract in my table of contents. However, in the generated table of content, the Title Page and Abstract share the same page number 1 (see the figure below)? But I used \thispagestyle{empty} in the title_page.tex and there is no page number on the title page. The first page starts with the abstract page. And the hyperlinks of Title page and Abstract both link to the title page. Can anyone tell me how to fix this? Thank you!

Edit: I added a mini problem-replicate example here my_thesis if anyone want to have a closer look.

Answer 1

Thanks to daleif. Here is one solution:

1.Delete the \addcontentsline{toc}{chapter}{Abstract} from main.tex file.

2.Add \phantomsection\addcontentsline{toc}{chapter}{Abstract} to the abstruct.tex above \textbf{My Title}.

3.compile twice.

Then the hyperlink of Abstract in the table of contents can point correctly to the abstract page.

The problem is that \addcontentsline{toc}{chapter}{Abstract} has no anchor to point to. So we can use \phantomsection to require hyperref jump to the correct page. You could also have a look at phantomsection.
