if then, expandafter condition with 2 parameters - show and hide boxes

Question

In topic: Display Box A or Box B if then condition

i have used only one paratemeter

Old Rule: condition with TextX

\TextX      |            Show             |         Hide

Value      |     \posterbox A            |          \posterbox B

Blank       |    \posterbox B              |         \posterbox A

Now I want to create New Rule: condition with 2 parameters: TextX, TextY

\TextX     |   \TextY     |  Show one box       |                 Hide 3 boxes

Value      |   Value      |  \posterbox A     |                    B,C,D

Value      |   Blank     |   \posterbox B            |             A,C,D

Blank     |    Value     |   \posterbox C         |                A,B,D

Blank     |    Blank     |   \posterbox D         |                A,B,C

Minimal working code:

\RequirePackage{filecontents}
\begin{filecontents*}{file.tex}
 No,TextX,TextY,TextZ,TextW
 1,x1,y1,z1,w1
 2,,y2,z2,w2
 3,,y3,w3,
 4,,,,w4
 5,x5,y5,,
 6,,y6,z6,w6
 7,x7,y7,z7,w7

\end{filecontents*}

\documentclass{article}
\usepackage[a4paper,landscape]{geometry}
\usepackage{filecontents}
\usepackage{datatool}
\usepackage{wrapfig}
\usepackage{xparse}
\usepackage{lipsum}
\usepackage{tikz}
\usepackage{tcolorbox}
\tcbuselibrary{poster}

\usepackage{bbding}
\usepackage{pifont}
\usepackage{enumitem, setspace}
 \tcbset{colframe=blue!75!black,colback=white}


 \DTLloaddb{file}{file.tex}

 \begin{document}

 \DTLforeach*
 {file}% Database
 {\No=No,\TextX=TextX,\TextY=TextY,\TextZ=TextZ,\TexW=TextW}
 {%
 \begin{tcbposter}[
  poster = {
    columns=1,

    spacing=3mm,
    height=14cm,
    width=12cm,
  },
]
%Box A
\expandafter\ifx\expandafter\relax\TextX\relax\else
\posterbox[colframe=red,width=5cm,height=5cm]{name=A,column=1}{
\includegraphics[height=3cm]{example-image-a} 
 \begin{enumerate}[wide, leftmargin =-1em, rightmargin=-1em]
\item A \TextX
\end{enumerate}
}\fi
%\newpage

%Box B
\expandafter\ifx\expandafter\relax\TextX\relax
\posterbox[colframe=blue,width=5cm,height=5cm]{name=B,column=1,xshift=5.0cm,yshift=0.0cm}{
 \begin{enumerate}

\item B \TextY
\item B \TextY
\item B \TextY
\end{enumerate}
\includegraphics[height=2cm]{example-image-b}
}\fi
\vspace{2cm}
%BoxC
\posterbox[colframe=green,width=5cm,height=5cm]{name=C,column=1,xshift=1.0cm,yshift=-7.0cm}{
\begin{enumerate}

\item C \TextZ
\item C \TextZ
\end{enumerate}
\includegraphics[height=2cm]{example-image-c}
}
%BoxD
\posterbox[colframe=black,width=5cm,height=5cm]{name=C,column=1,xshift=8.0cm,yshift=-7.0cm}{
\includegraphics[height=2cm]{example-image-duck}
 \begin{enumerate}

\item D \TextW
\item D \TextW
\end{enumerate}

}
\end{tcbposter}
\newpage
}

\end{document}

Please update code with new rule: 2 paramters

Thanks

You could extend the idea from your previous post and do this by having multiple branches of \if-statements like

\expandafter\ifx\expandafter\relax\TextX\relax
  \expandafter\ifx\expandafter\relax\TextY\relax\else
  ...
\fi\fi...\fi

but this will end up looking pretty nasty. Instead, the code below defines a command \FourWayChoice that accepts 6 arguments and is used as

\FourWayChoice{\TextX}{\TextY}{Box A}{Box B}{Box C}{Box D}

where the different "boxes" are chosen as per the table in the OP. The definition of the \FourWayChoice macro is pretty easy, partly because I use LaTeX3. You can use the same idea to answer the previous post.

Using this code, page 2 of the MWE looks like this:

Here is the full code:

\RequirePackage{filecontents}
\begin{filecontents*}{file.tex}
 No,TextX,TextY,TextZ,TextW

 3,,y3,w3,

 5,x5,y5,,
 6,,y6,z6,w6
 7,x7,y7,z7,w7

i use your above code but there are 4 pages. Other pages: 2,4,6 do not display? — latexforti, May 11 '19 at 07:31
@latexforti Note that I commented out the \newpage at the bottom. If I remove then comment then this generates 7 pages for me, as it should since file.tex has 7 entries. — , May 11 '19 at 08:52

You could nest some \if conditionals:

\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.dat}
 No,TextX,TextY,TextZ,TextW
 1,x1,y1,z1,w1
 2,,y2,z2,w2
 3,,y3,w3,
 4,,,,w4
 5,x5,y5,,
 6,,y6,z6,w6
 7,x7,y7,z7,w7
\end{filecontents*}

\usepackage{enumitem, setspace}
\tcbset{colframe=blue!75!black,colback=white}

\DTLloaddb{file}{\jobname.dat}

\newcommand{\select}[2]{%

    \if\relax#2\relax
      \selectB % 10
    \else
      \selectA % 11
    \fi
  \fi
}
\newcommand{\selectA}{%
  \posterbox[colframe=red,width=5cm,height=5cm]{name=A,column=1}{%
    \includegraphics[height=3cm]{example-image-a} 
    \begin{enumerate}[wide, leftmargin =-1em, rightmargin=-1em]
