Re: [mapserver-users] Differerent output format for GetFeatureInfo - template strategy

Thank you for suggestions concerning the GetFeatureInfo

For one reason or another, I have implemented the suggestion of having all layers bundle, on mapserver template like:

// mapserver template

[resultset layer="Acrisols"]{

"type": "FeatureCollection",

[/resultset]

[resultset layer="Albeluvisols"]{

type": "FeatureCollection",

[/resultset]

I have 62 layers (more or less) per mapfile and don't see any speed penalty using this approach

Initially, I tried to use [include file=common.js] instead of the above verbose content, but when using the include approach (my favourite), the variables on the included generic template ([x], [y],[value_0],[class]) wouldn't be expanded to their values. Is template variable inherance implemented or I just bumped into a bug ??

I didnt tested the suggestion from Seth (to many files) , but interresting

Changing the format filename for each layer might be a possibility?

OUTPUTFORMAT: FORMATOPTION: FILENAME (must have a MAP VALIDATION pattern)

Thank you for the tips and suggestions

Dear mapserver community

I am trying to set a WMS where the a GetFeatureInfo will support more than one INFO_FORMAT, currently I have text/html implemented [1], which uses a layer level implementation. This works fine when you have only one format [2].

Now I need to have 2 formats, html and geojson/json.

Documentation is very clear that the best strategy is to use the OUTPUTFORMAT, each output format associated with a specific template, this works fine .

Problem is that all examples that I see using outputformat have a very clear layer name indication (below is nums)
// mapserver template
[resultset layer=mums]
This simplely doesn't work if you have 100 layers on a mapfile and we need a output format template for all of them, I have search for some generic parameter that could relay the layer name being used but no luck. With setting the layer name it doesn't work!! And arguments can't be replaced

Question :
- How can I have a generic [resultset ] that can be use by multiple layers???? [3]
- Template at layer level works good but I don't think we can support 2 formats there, is this correct???

System:
mapserver7.6.0 gdal2.4 proj4

Thank you
