Hi! I've added the ParserFunctions extensions which allows to use #if: #ifexpr: and so on.
I've wrote the following template
__NOEDITSECTION__ {{ #if: {{{1}}} |'''From ''' [[:Category:{{{1}}} | {{{1}}}]] [[Category:{{{1}}}]] }} {{ #if: {{{2}}} |, [[:Category:{{{2}}} | {{{2}}}]] [[Category:{{{2}}}]] }} {{ #if: {{{3}}} |, [[:Category:{{{3}}} | {{{3}}}]] [[Category:{{{3}}}]] }} {{ #if: {{{4}}} |, [[:Category:{{{4}}} | {{{4}}}]] [[Category:{{{4}}}]] }} {{ #if: {{{5}}} |, [[:Category:{{{5}}} | {{{5}}}]] [[Category:{{{5}}}]] }}
When I call it with 5 parameters it is all OK, but When calling it with three parameters as follows:
{{From | Ángel Gregorio Villoldo | Angel Labruna | pepe soriano}}
I get
From Ángel Gregorio Villoldo , Angel Labruna , pepe soriano , [[:Category:{{{4}}} | {{{4}}}]] :[[Category:{{{4}}}]] , [[:Category:{{{5}}} | {{{5}}}]] [[Category:{{{5}}}]]
Which is wrong. I've tried many work arounds like adding an as"else" in this way:
{{ #if: {{{2}}} |, [[:Category:{{{2}}} | {{{2}}}]] [[Category:{{{2}}}]] | }} but it didn't work. Seems to bw that this function has some problems with empty parameters. I believe that using named parameters might be the solution but I need unnamed parameters. If anybody knows how to cope this issue please, let me know.
I've also tried to add a default empty value
{{ #if: {{{2|}}} |, [[:Category:{{{2}}} | {{{2}}}]] [[Category:{{{2}}}]] | }}
with the same result.
Am I making a mistake? Is there any workaround for this?
Thanks,
Luis
