Using Automator to apply tags to selected files

OK changed...

use taglib : script "Tag_cafe"
use scripting additions

on run {input, parameters}
	
	repeat with aFolder in selectedFolders
		try
			# add both custom tags and avoids duplicate tag names
			taglib's add_tags(aFolder, "On NAS", "Not yet on LMS")
		on error errMsg number errNum
			set success to false
			display dialog "Error applying tags to " & (name of aFolder) & ": " & errMsg buttons {"OK"} default button "OK"
		end try
	end repeat
	
end run

Still getting The variable selectedFolders is not defined.

OK, amended AppleScript code to

use taglib : script "Tag_cafe"
use scripting additions

on run {input, parameters}

tell application "Finder"
	-- Get the selected folders in Finder
	set selectedFolders to selection
	
	-- Check if there are any selected items
	if selectedFolders is {} then
		display dialog "No folders selected." buttons {"OK"} default button "OK"
		return
	end if
end tell

-- Initialize a success flag
set success to true

-- Loop through the selected items
repeat with aFolder in selectedFolders
	try
			# add both custom tags and avoids duplicate tag names
			taglib's add_tags(aFolder, "On NAS", "Not yet on LMS")
		
	on error errMsg number errNum
		set success to false
		display dialog "Error applying tags to " & (name of aFolder) & ": " & errMsg buttons {"OK"} default button "OK"
	end try
end repeat

-- Display a dialogue only if there was an error
if success is false then
	display dialog "One or more tags could not be applied." buttons {"OK"} default button "OK"
end if

end run

when run get, now get this error

Error applying tags to MySelectedFolder: Can’t make «class cfol» "MySelectedFolder" of «class cdis» "ExternalHDD" of application "Finder" into the expected type.

Thanks for your reply.

OK, have taken your suggestions on board and have amended the code to:

use taglib : script "Tag_cafe"
use scripting additions

on run {input, parameters}
	
	-- Initialize a success flag
	set success to true
	
	-- Loop through the selected items
	repeat with aFolder in input
		try
			# add both custom tags and avoids duplicate tag names
			taglib's add_tags(aFolder, "On NAS", "Not yet on LMS")
			
		on error errMsg number errNum
			set success to false
			set folderName to name of (info for aFolder)
			display dialog "Error applying tags to " & folderName & ": " & errMsg buttons {"OK"} default button "OK"
		end try
	end repeat
	
	-- Display a dialogue only if there was an error
	if success is false then
		display dialog "One or more tags could not be applied." buttons {"OK"} default button "OK"
	end if
	
end run

Unfortunately, the result of this was no tags being applied to where the folder was being copied from and a single green tag being applied to where it was copied to.

Yes, that's what I want. For the tags to be applied to the folders at the source.

Going back to your earlier comment, I understand why you said there is no need for

tell application "Finder"
	-- Get the selected folders in Finder
	set selectedFolders to selection
	
	-- Check if there are any selected items
	if selectedFolders is {} then
		display dialog "No folders selected." buttons {"OK"} default button "OK"		return
	end ifend tell



this code, as yes, the whole workflow is dependent on a selection of folder(s) in Finder, yet it's not working unless some code in that section is included, maybe just the

set selectedFolders to selection

I don't know, as you've no doubt grasped, I'm not a coder and just trying different things to see what works.

Could it be to do with the prior steps in the Workflow?

So plain language, my steps are:

• copy the selected folder(s) in Finder to the destination
• rename those folders in the destination if applicable
• apply the two custom tags to the folders at source

Right, so if I understand correctly, it's what happens after the last Rename Finder Items, that in the AppleScript it appears that it is necessary to specify the originating Folders?

Is that the reason why it works with the tell application "Finder" piece of code?

If that works, is it not best practice to include it or is there a better more elegant way to specify in the AppleScript to assign the originating folder or list of originating folders as a variable?

Thanks for your continued engagement, hope it doesn't feel too much like having your fingernails pulled out… 😉

Also, do I need to change Custom Green tagname & Custom Gray tagname to the actual custom names or should it take those automagically due to the script bundle you wrote? Thank you.

OK, get the following error:

Error applying tags to MySelectedFolder: The variable taglib is not defined.

Hang on, think I may have this, will try something else.
