Dynamic file name if a specific named field exists or not.

[Erik28899879fgvc]

I have created folder level scripts with corresponding buttons to create unique file names each time based on information in the file and the users who saved the file to a specified location. 

Ocassionally there are files that will go to the same location, but the file itself does not have the named fields in my script and instead of created a second set of buttons and script for these types of files I would like the script to be able to identify if the file has the named field to use one naming convention and if not use another. 

I can't seem to find the correct syntax or functions to do this. Below is a sample script with my line of thinking to complete this. 

//Create Filename
function Name(){
if (doesObjectExists("Original Accession")==true){
var myFileName = this.getField("Original Accession").value + " " + getLoginName() +" " + myDateString();
}
else{
var myFileName = myIdString() + " " + getLoginName() +" " + myDateString();
}}

Later in the script i have a save as comand to a location with " +myFileName+".pdf". I do understand these need to be trusted functions and I have that set in place the bug I am ecountering is that the script doesn't understand myFileName. If I get rid of the if/else statement i recognizes one or the other of the naming conventions.

If this.getField("Original Accession") is null then the field doesn't exists.

It doesn't seem to work for me. I still get the same reference error of myFileName is not definted. 

I wrote 

function Name(){
if (this.getField("Original Accession")==null){
var myFileName = this.getField("Original Accession").value + " " + getLoginName() +" " + myDateString();
}
else{
var myFileName = myIdString() + " " + getLoginName() +" " + myDateString();
}}

is the problem that I need to definte myFileName outside the statement? Maybe something along the lines of 

//Create Filename
var myFileName = function(){
if (this.getField("Original Accession")==null){
var Name = this.getField("Original Accession").value + " " + getLoginName() +" " + myDateString();
}
else{
var Name = myIdString() + " " + getLoginName() +" " + myDateString();
}}

Have a closer look at your code... This part has a clear issue with it:

if (this.getField("Original Accession")==null){
var Name = this.getField("Original Accession").value + " " + getLoginName() +" " + myDateString();
}

Please forgive me as my knowledge in coding is patchy at best. I am also constrained by using the Adobe Standard and not the Pro version so the debuging tool is hard for me to access and truly use. I am just unable to wrap my head around the problem to think of the solution.

If only use a single naming convention 

var myFileName = this.getField("Original Accession").value + " " + getLoginName() +" " + myDateString();  where "Original Accession is a field in the file. the LoginName is the users windows username, and the Date String is a time stamp it works when i use the save as function 

this.SaveAs("file path/"+ myFileName +".pdf")  

When i try to make a statment that defines what myFileName depenedent if "Original Accession" fields exists or not i get the reference error if undefitend myFileName.

What your current code is trying to do is basically this:

- If the field "Original Accession" doesn't exist, use its value in the new file name.

That doesn't make sense.

Thank you so much. That was exactly my problem plus I needed to define that the variable myFileName existed outside that statement. 

Thank you again for your help. my code now looks like this and it works as needed.

//Create Filename
var myFileName;
if (this.getField("Original Accession") != null){
var myFileName = this.getField("Original Accession").value + " " + getLoginName() +" " + myDateString();
}
else{
var myFileName = myIdString() + " " + getLoginName() +" " + myDateString();
}
