[TYPO3-dev] RealURL: bypass and lookupTable, missing feature?

[Andreas Förthner]

Hi,

I already posted this to the english list, but there nobody knew 
anything about it. Now I have searched a bit in the sources an found out 
that this just might not be possible. Here again the Problem:

I am configuring the RealURL Extension for my page. There I have some 
Parameters for my own extension. These parameters can be existant on any 
page, because the plugin could be everywhere. And it's also possible 
that there are just a few of these parameters. Just to make this clear: 
   I am linking to some records in the database those records could be 
associated to a subcategory or not, so the subcategory parameter is only 
  existant if the record is associated to one. Of course this shoul be 
the same in the URL.

What I did was the configuration of those parameters as fixedPostVars. 
This work so far very good, everything is mapped, but if there is one 
parameter missing the URL gets an //. Meaning if one of the parameters 
is there, all of the parameters defined are tried to get translated, if 
there is one missing in the original url I get an empty one, ending in a 
double slash.

I think the Problem is that there is no possibility to bypass an 
parameter that is not in the database lookup. So there should be 
something like the noMatch for the valueMap for the lookupTable. Once 
the script runs into this elsif case the parameter is compiled in every 
case. So if the DB lookup returns nothing (also because the parameter is 
just not set in the original URL) the manipulated URL gets an empty 
virtual pass, ending in those two slashes.

Or why are all parameters mapped even though they are not existant? Why 
not add an additional if when filling the params Array, that checks if 
the parameters is existant. If not this one should automatically bypassed.

Is there something speaking against such a behavior?
