Unknow fields of layer for geoprocess

[AvixiSeb]

Hey,

I would like to create a script/tool ​​that will be used in web (geoprocess)

The idea is simple: Input is a layer (not fixed, so technically the fields layers can be different)
How can I do so that my tool can receive any layer, with different fields ?

Currently, by doing Share As of the Geoprocess Result, the Fields remain fixed according to the Layer that I used for the example..

Thanks for your help !

Hi, do I understand correctly that you are creating python geoprocessing tool?

If yes, you can use ListFields to get list of fields of any recieved layer.

It mainly depends on what do you want to do with this information.

If you need to receive a layer from JavaScript for this tool, the input type (in toolbox script) should be Feature Set. Is this what you are looking for?
