# Getting the path of linked (smart) object / PS Bug?

Hello All

i'm trying to read the path of the linked object/layer trough script. The path information seems to be available in the Layers properties panel (see screenshot 1).

When i try to use the command "reveal in finder" from within Photoshop, i do get an Error "Could not complete your request because of a program error."

So, i'm not able to use Scriptlistener to use the code for that.

Does anyone have a working AM code for this function available and knows why i do get this error on my side (on all psd documents i tried).

alert(app.activeDocument.activeLayer.filePath);


EDIT:

found this code that checks if there is a linked smart object and returns it's path.

Unfortunately i can't get it working like:

//Pseudocode:

{
var activeDesignPath = activeLayer.filePath;
} else {
// ignore ALL errors and continue (next layer will then be checked)
};

// Export/save as jpg to the root Folder of the linked smart object.
app.activeDocument.saveAs((new File(activeDesignPath + "/_Files Export/with GTO Background" +'/' + activeColor + ' ' + basename + ' ' + designDoc.activeLayer.name +'.jpg')),jpegOptions,true);


Original Script:

  if (app.documents.length)
{
var doc = app.activeDocument;
for (var ilayer = 0; ilayer < doc.artLayers.length; ilayer++)
{
var layer = doc.artLayers[ilayer];
if (layer.kind == LayerKind.SMARTOBJECT)
{

var ref = new ActionReference();
ref.putIdentifier(charIDToTypeID('Lyr '), layer.id );

var desc = executeActionGet(ref);
var smObj = desc.getObjectValue(stringIDToTypeID('smartObject'));
}
}
}

The code you found works for linked smart object layers it will through an error if the object is not a linked file. You can use a try catch to note the and ignore none linked smart object layers.

function processSmartObj(obj) {

var localFilePath = "";

var ref = new ActionReference();

ref.putIdentifier(charIDToTypeID('Lyr '), obj.id );

var desc = executeActionGet(ref);

var smObj = desc.getObjectValue(stringIDToTypeID('smartObject'));

try {

alert("Layer " + obj.name + ' linked file is"' +  localFilePath + '"');

}

catch(e) {}

return localFilePath;

}

You could put some boilerplate around the process to structure the code an make it  more readable  for example process all layer in a document may look something like this.

Hi, I also tried getting the localfilepath with the snippet you shared, but do you know how can we replace this localFilepath with a new file or how do we relink it to other file stored on disk programmatically. If you can spare a couple of minutes, can you please have a look at - How to customize the linking file path in recorded photoshop actions. & try to help out .

• ###### 3. Re: Getting the path of linked (smart) object / PS Bug?

Hi

Use this code:

(desc = new ActionDescriptor()).putPath( cTID( "null" ), new File( "C:\\Path\\to\\your\\file.psb" ) );
executeAction( sTID( "placedLayerRelinkToFile" ), desc, DialogModes.NO );


• ###### 4. Re: Getting the path of linked (smart) object / PS Bug?

One question though in this snippet I think we are grabbing the current selected layer & then replacing its contents.
Can we do a select layer by name first & then replace / relink the file in the same way as you are doing with executeAction()

or the alternate approach would be to

1) select a layer by name in photoshop programatically first,

2) then replace the selected files contents.

So, now (2) can be done with the snippet you shared, how can we get (1) done so that we can setup a batch process to replace & export relinked graphics.

Nevermind, I got the selected layer with this -

app.activeDocument.activeLayer=app.activeDocument.artLayers.getByName("bluesock");


Thanks for the time & help though.

• ###### 6. Re: Getting the path of linked (smart) object / PS Bug?

To select a layer by name use this function:

function makeLayerActiveByName(name) {
(ref = new ActionReference()).putName( sTID('layer'), name);
(desc = new ActionDescriptor()).putReference( cTID('null'), ref ), desc.putBoolean( cTID('MkVs'), false );
executeAction( sTID('select'), desc, DialogModes.NO );
}

Hey - nice to see you here again. I just had to link a topic where you marked my answer as correct, as I if I am right r-bin showed you there how to check path of Linked Placed Layer. You simply came up now in good time btw I just noticed I have edited last post of final sentence in that topic you did not see yet. Could you please finally answer to my question?

Actions can not use logic without using a script or using interactive steps so you can add the logic to choose the replacement etc.  If you want to completely automate your process you would need to script it.

I think if you look at Photoshop's menu Layer>Smart Objects>option  you will see what your options are for what you want to do.  Keep in mind though all Smart Object layers have an associated transform for the layers content that is not replaced or change if you update the layers object or replace it.  The Size and resolution of the object must not be changed for the associated transform to work correctly. The object need to be the correct size.

As far as I know you would either replace the smart object layers Object or Edit the Linked Files and change its content.  Relink to may also be an option I have never seen it scripted and I have never used placed linked files.

In a recent thread c.pfaffenbichler posted some code to open and edit a smart Object layer.  Re: Batch replace smart objects in mockup file

If you find the  object is a local linked image file you may be able to just open the file in  Photoshop and change the documents content and then save the linked file over itself.  When your script ends. I would expect Photoshop would Updated the Smart Object layers content for the linked file has changed.   That may be just like c.pfaffenbichler would do opening the smart object and editing it.  If the liked image file however, was a .svg or .ai file Illustrator may open if you open the linked file in either case and your script could not do the AI processing. If it was a Camera RAW file object ACR may open and you will not be able to change the image.  The may be pit falls one could fall into trying to edit the smart object IMO.  All Smart Object are not the same.  They are your Assets you should know what the objects are thate you are working with.]
