Using datasets

[flex_n00b]

Hi,

In a photoshop dataset, I wish to do the following-

1. save as .jpg

2. name the file using a variable used in the document

how can this be done? i am using cs4

[Michael_L_Hale · Accepted solution]

Here is one way to save the sets as jpgs. It assumes that the activeDocument has datasets defined and uses the first fieldname in the dataset csv as the savename for the jpg.

fileImportDataSets = function(file) { 
    var desc = new ActionDescriptor(); 
        var ref = new ActionReference(); 
        ref.putClass( stringIDToTypeID( "dataSetClass" ) ); 
    desc.putReference( charIDToTypeID( "null" ), ref ); 
    desc.putPath( charIDToTypeID( "Usng" ), new File( file ) ); 
    desc.putEnumerated( charIDToTypeID( "Encd" ), stringIDToTypeID( "dataSetEncoding" ), stringIDToTypeID( "dataSetEncodingAuto" ) ); 
    desc.putBoolean( stringIDToTypeID( "eraseAll" ), true ); 
    desc.putBoolean( stringIDToTypeID( "useFirstColumn" ), true ); 
executeAction( stringIDToTypeID( "importDataSets" ), desc, DialogModes.NO ); 
}
applyDataSet = function(setName) { 
    var desc = new ActionDescriptor(); 
        var setRef = new ActionReference(); 
        setRef.putName( stringIDToTypeID( "dataSetClass" ), setName ); 
    desc.putReference( charIDToTypeID( "null" ), setRef ); 
executeAction( charIDToTypeID( "Aply" ), desc, DialogModes.NO ); 
}
getDataSetNames = function(csvFileRef) {
     _ftn = function(string){
          var csvItems = string.split(",");
          datasetName = csvItems[0]          
          return datasetName;
     }
     csvFileRef.open();
     var datasetArray = new Array();
     var i = 0;
     while (csvString = csvFileRef.readln()) {
          if (csvString.length < 2) continue; // Skip empty lines
       datasetArray[i] = _ftn(csvString);  
       i++;
     }
     csvFileRef.close();
     return datasetArray;
}
// jpeg options used for all the saves
var jpgOptns = new JPEGSaveOptions();
     jpgOptns.formatOptions = FormatOptions.STANDARDBASELINE;
     jpgOptns.embedColorProfile = true;
     jpgOptns.matte = MatteType.NONE;
     jpgOptns.quality = 8; 
//prompt for file
var csvFileRef = File.openDialog("Please select CSV file"); 
fileImportDataSets(csvFileRef); //inport the CSV file into the template
var datasetNames = getDataSetNames(csvFileRef);// set up the dataset array
//setup a loop for your data set names 
for (i=1; i < datasetNames.length; i++) {
     applyDataSet(datasetNames[i]);
     //edit the file if needed 
     //save the file. Here I use testItem.contents of layer 'name' as the filename
     app.activeDocument.activeLayer = app.activeDocument.artLayers.getByName("name"); 
     jpgSaveFile = new File(csvFileRef.path + "/" + app.activeDocument.activeLayer.textItem.contents + ".jpg");
     app.activeDocument.saveAs (jpgSaveFile ,jpgOptns , true, Extension.LOWERCASE);
}//loop to next data set

Found this linked from another thread and I'm a bit confused by its use. Is it supposed to loop automatically and save multiple JPG's one after the other with the data set data and filename applied?  I tried it but all it does is save the last data set with name after churning a few seconds. I have about 80+ data sets in a CSV on the first column.

I corrected the script that now it works.

To make it loop through all dataset names, just change getDataSetNames function to this : 

getDataSetNames = function(csvFileRef) {

     _ftn = function(string){

          var csvItems = string.split(",");

          datasetNames = csvItems[0]          

          return datasetNames;

     }

     csvcsvFileRef.open();

     var datasetArray = new Array();

     var csvLine = csvFileRef.length; 

     var read;

     for (var i = 1; i < csvLine; i++) {

        read = csvFileRef.readln();    

        if (read.length < 2) continue; // Skip empty lines

            datasetArray = _ftn(read);

     }       

     csvList.close();

     return datasetArray;

}

[dphong31415]

Update : 

datasetArray = _ftn(read);

Need to change to this for store every line in datasetArray (else it will only store one value)

datasetArray.push(_ftn(read));

I'm getting an error when I run it on line 52,  "Error 1302, No such element. "... app.activeDocument.activeLayer = app.activeDocument.artLayers.getByName("name");

Any ideas?

[ishook]

Nevermind! I just renamed my variable from 'filename' to what you had as 'name' and it worked great. This 10 year old java script is a life saver.

In the ten that yeares Mike Hale has passed but he is still helping us here Rest In Peace Mike thanks....

[Eager_Enchantment5FD2]

I've been running into a wall with this exact issue. Can you go more into detail what you did here?

[rejin89342351]

Hmmm the dataset is not getting applied automatically for me on my PSD template

The window comes up to select the csv, I select it and it saves the jpg. However it saves the jpg with my template as is, without the data applied

I'm having to manually go into the menu under:
Image > Variables > Datasets
then since the dataset is already loaded, I need to click "Apply"
only then it applies the set

Any thoughts why its not happening automatic?

This is with PS 2019 and WIndows 10

[ishook]

The script is best used for "behind the scenes" saving. If you do really want it to update your open PSD, you'll have to continue using the method you mentioned above.

[rejin89342351 · Accepted solution]

I got it working by checking the listener for the menu item's apply dataset

Copied that into my code and it works fine

However, I have various dataset files in an array and processing it and saving

For some reason its only doing the 1st file and not cycling through the rest of the files
(no errors, but only does the 1st dataset file)

[rejin89342351]

Nevermind, all good and working now

I had 2 nested for loops, each using the same i to increment, duh!

@rejin89342351 – Thank you for your comment! I have updated the code, and tested it in v2019, v2021, v2024:
