create group from existing layers

[mikew78101280]

I have 2 layers that I wish to place in a new group called DATA, they have just been linked by the follwing code and so I can learn a bit more is it better to create the group first and add layers to it or does that not matter?

activeDocument.layers['INFO'].link(activeDocument.layers['ICONS']);

Do you want to use DOM-code or AM-code? 

Referencing Layers by name seems a bit risky by the way. 

If you created the Layers withing the Script you may want to define them as a var right away. 

[mikew78101280]

In all honesty I do not know the difference between the 2 types of code

The layer names will always be the same as they are created in the script

I have just found a way to create a Group (but this may not be the best method obviously)

	var docRef = app.activeDocument;
	var newGroup = docRef.layerSets.add();
	newGroup.name = "DATA";

so if I add that early enough I can use the following to add the layers to the group using after each new layer

activeDocument.activeLayer.move(docRef.layerSets["DATA"], ElementPlacement.INSIDE);

but when I try to run this I get an error

	activeDocument.layers['INFO'].link(activeDocument.layers['ICONS']);

lrs = (aD = activeDocument).layers
inf = lrs['INFO'], icns = lrs['ICONS']

//	use here code to move layers to layerSet

inf.link(icns)

That linked the layers fine.

Select both layers (to be grouped) and use this code:

 sTT = stringIDToTypeID;
 
(ref1 = new ActionReference()).putClass(sTT('layerSection'));
(dsc1 = new ActionDescriptor()).putReference(sTT('null'), ref1);
(ref2 = new ActionReference()).putEnumerated(sTT('layer'), sTT('ordinal'), sTT('targetEnum'))
dsc1.putReference(sTT('from'), ref2); (dsc2 = new ActionDescriptor()).putString(sTT('name'), 'DATA')
dsc1.putObject(sTT('using'), sTT('layerSection'), dsc2), executeAction(sTT('make'), dsc1)

This created the new group above existing layers but only put the top layer in the group.

Did you select both layers like I said?

[mikew78101280]

No, my bad, something else I need to learn how to do

sTT =stringIDToTypeID, dsc = new ActionDescriptor(), ref = new ActionReference()
for(i = 0; i < (a = ['INFO', 'ICONS']).length;) ref.putName(sTT('layer'), a[i++])
dsc.putReference(sTT('null'), ref), executeAction(sTT('select'), dsc)

I think I will be owing you a few beers at this rate, runs very nicely

Many

thanks
