Rant on my favourite topics : LC server with a side-dish of on-rev :-)

[Alex Tweedly]

Hi Ralf,

Thanks - but that's actually a different  JSON extension :-) That is an 
LCB library that defines JsonExport and JsonImport.

However, I looked around some more, and found Tools/Ext/mergJSON-1.0.38

That's an external which defines mergJSONEncode and mergJSONDecode

But the docs for it  (api.lcdoc) describe how it might be expected to be 
used, and include ArryToJSON and JSONToArray functions (less than 20 
line of LCS). So I copy/pasted those lines into my own LC Server script 
- and now everything works (at least for simple tests).

So clearly mergJSON is already included in LC Server - and you only need 
to include the following lines for yourself

     function ArrayToJSON pArray,pForceRootType,pPretty
         repeat for each key tKey in pArray
             if pArray[tKey] is an array then
                 put "}"&ArrayToJSON(pArray[tKey]) into pArray[tKey]
             end if
         end repeat
         return(mergJSONEncode("pArray",pForceRootType,pPretty))
     end ArrayToJSON

     function JSONToArray pJSON
         local tArray,tKeys
         repeat for each line tKey in mergJSONDecode(pJSON,"tArray")
             put JSONToArray(tArray[tKey]) into tArray[tKey]
         end repeat
         return tArray
     end JSONToArray

-- Alex.

No problem - just take the rest of the data, stick in a JSON-encoded cookie, and redirect back to the revIgniter script on success.
