APA style quotes, year with parentheses, footcites, ibidem

Question

I would like

1. my citation style to be a footnote Author (Year)
2. for the entire Author (Year) to be a hyperlink to the bibliography
3. for repeated citations to be Ibid

So far I can almost do it all.

The code below compiles to give the correct hyperlink and the correct ibidem, but the citation is Author Year (no parentheses). If I change each autocite to footcite I get the correct hyperlink and the correct citation, but the wrong ibidem: Author (ibid.).

If I make the first autocite a footcite, I get the intended result ... but that means I have to keep track of autocite and footcite, which defeats the purpose of automatic ibidem.

Answer 1

We can just redefine the normal cite macro to wrap the year in parentheses, in order to avoid problems with other cite commands we choose a new name for the changed macro cite:paren:labelyear+extrayear

\renewbibmacro*{cite}{\printtext[citehyperref]{%
  \global\boolfalse{cbx:loccit}%
  \iffieldundef{shorthand}
    {\ifthenelse{\ifciteibid\AND\NOT\iffirstonpage}
       {\usebibmacro{cite:ibid}}
       {\ifthenelse{\ifnameundef{labelname}\OR\iffieldundef{labelyear}}
          {\usebibmacro{cite:label}%
           \setunit{\addspace}}
          {\printnames{labelname}%
           \setunit{\nameyeardelim}}%
        \usebibmacro{cite:paren:labelyear+extrayear}}}
    {\usebibmacro{cite:shorthand}}}}

\renewbibmacro*{cite:paren:labelyear+extrayear}{%
  \iffieldundef{labelyear}
    {}
    {\printtext[parens]{%
       \printfield{labelyear}%
       \printfield{extrayear}}}}

There is no need to change the \footcite command
