I have created a BibLaTeX library, which I use to organize all my oral and poster presentations. It is in fact a customized library with new data types and cite commands. I got all ideas from here and here.
After some time of programming, I got the following code, which works quite well. I can use my own command \printcontrib{BiB_entry} in any text, but also I can do some listing at the end by, e.g., calling all Bib entries via the latter command.
Before I show the code, I would like to apologize already here that my code is probably some (evil?) hack. ;-)

The output looks like this:
So far so good. Now, there might be some entries in one BibLaTeX entry (see, e.g., Oral_2016_1 => Country = {}), that have no text inside the two {} because some info is missing (note that I would like to keep these brackets due to a couple of reasons ... .)
I would like to have a 'if ... do ... else do ...' part in the code, which checks if an entry is 'empty', so here Country = {}. Otherwise, as it is the case here, the are two brackets displayed in the text ().
I would like to have this if conditioning in particular in this command:
% My own command, which puts into format and prints the contribution.
\newcommand{\printcontrib}[1]{
\citeauthor*{#1},
\citetitle*{#1},
\citeevent{#1},
\citecity{#1}

% This works, but there is no 'if' that might find an empty 'country' field.

(\citecountry{#1}),

% \ifdim\strlen=0\else(\citecountry{#1})\fi,
% \let\strlen\relax
%
\citedate{#1} (\citeyear{#1})
}
The (\citecountry{#1}) command (note the ( and ) brackets) shall be only executed, if the entry country has some text, in other words, is not Country = {} in the BibLaTeX file.
I tried out a dozen of things. For instance, I tried several if conditions with help of the ifmtarg, xstring and ifthen packages but without any success. The only half-solution in the % quotation (below the text % Here is my first test in the MWE) somewhat works, however, with errors (you have to uncomment this such that it is compiled by LaTeX).
\printcontribwith\newcommandby sticking several\cite...together is really bad style inbiblatex. A command like this will not be able at all to handle pre or postnotes and multiple citations properly without much extra work, one should always use\DeclareCiteCommand. – moewe Jan 25 '17 at 08:15
