Re: Batch replace smart objects

Where do I paste the above in the existing script? and do I have to change the names of anything to match the name of my layer?  Here's what I'm using:

#target photoshop

if (app.documents.length > 0) {

var myDocument = app.activeDocument;

var theName= myDocument.name.match(/(.*)\.[^\.]+$/)[1];

var thePath = myDocument.path;

var theLayer = myDocument.activeLayer;

// psd options;

psdOpts = new PhotoshopSaveOptions();

psdOpts.embedColorProfile = true;

psdOpts.alphaChannels = true;

psdOpts.layers = true;

psdOpts.spotColors = true;

// check if layer is smart object;

if (theLayer.kind != "LayerKind.SMARTOBJECT") {alert ("selected layer is not a smart object")}

else {

// select files;

if ($.os.search(/windows/i) != -1) {var theFiles = File.openDialog ("please select files", "*.png;*.jpg;*.psd;*.tif", true)}

else {var theFiles = File.openDialog ("please select files", getFiles, true)};

if (theFiles) {

// work through the array;

          for (var m = 0; m < theFiles.length; m++) {

// replace smart object;

                    theLayer = replaceContents (theFiles[m]);

                    var theNewName = theFiles[m].name.match(/(.*)\.[^\.]+$/)[1];

//save PSD;

                    myDocument.saveAs((new File(thePath+"/"+theName+"_"+theNewName+".psd")),psdOpts,true);

                    }

          }

}

};

////// get psds, tifs and jpgs from files //////

function getFiles (theFile) {

     if (theFile.name.match(/\.(psd|tif|jpg)$/i) != null || theFile.constructor.name == "Folder") {

          return true

          };

     };

////// replace contents //////

function replaceContents (newFile) {

// =======================================================

var idplacedLayerReplaceContents = stringIDToTypeID( "placedLayerReplaceContents" );

    var desc3 = new ActionDescriptor();

    var idnull = charIDToTypeID( "null" );

    desc3.putPath( idnull, new File( newFile ) );

    var idPgNm = charIDToTypeID( "PgNm" );

    desc3.putInteger( idPgNm, 1 );

executeAction( idplacedLayerReplaceContents, desc3, DialogModes.NO );

return app.activeDocument.activeLayer

};

Sorry for the basic questions..
