Anyway here’s my favourite wrong-uns:

The purpose of the script is to export single page PDFs from a multi-page InDesign CS2 document where the page numbering has been set via page Numbering and Section Options. PDFs are exported to a predetermined PDF setting: “PDF_X-1a with Bleed & co” in my case. The resulting file PDFs are named with a three-digit prefix corresponding to the page number in the InDesign document and a user defined base name – defined when the script is run.

A basic version of this script is supplied by Adobe in with the extras for an InDesign install but unfortunately that falls over when there is a Named Section present. Getting a stray Named Section in your document is very easy. Easier for some users mind – but still very easy. Peter – I still owe you a beer or three…

Here is the magic script:

#target indesign 

if(app.documents.length != 0)
   {
   var myFolder = Folder.selectDialog ("Choose a Folder");
   if(myFolder != null)
      {
      myExportPages(myFolder);
      }
   }
else
   {
   alert("Please open a document and try again.");
   } 

function myExportPages(myFolder)
{
var myPageName, myFilePath, myFile;
var myDocument = app.activeDocument;
var myDocumentName = myDocument.name;
//This next line sets the PDF export Setting
var myPDFExportPreset = app.pdfExportPresets.item("PDF_X-1a with Bleed & co")
var myDialog = app.dialogs.add();
with(myDialog.dialogColumns.add().dialogRows.add())
   {
   staticTexts.add({staticLabel:"Base name:"});
   var myBaseNameField = textEditboxes.add({editContents:myDocumentName, minWidth:160});
   }
var myResult = myDialog.show({name:"ExportPages"});
if(myResult == true)
   {
   var myBaseName = myBaseNameField.editContents;
   myDialog.destroy();
   // Remember the state of each section prefix
   var section_states = myDocument.sections.everyItem().includeSectionPrefix;
   // Get all section-prefix names
   var section_names = app.activeDocument.sections.everyItem().name;
   // Enable all section prefixes
   myDocument.sections.everyItem().includeSectionPrefix = true;
   // Create two parallel arrays with page numbers:
   // one with numbers preceded by section prefixes,
   // the other with bare page numbers
   var page_ranges = [];
   var filename_pagenames = [];
   for(var i = 0; i < myDocument.pages.length; i++)
      {
      page_ranges.push (myDocument.pages.item(i).name);
      var temp = strip_section (myDocument.pages[i].name, section_names);
      filename_pagenames.push (("00" + temp).slice(-3))
      }
   // Restore the section-prefix settings
   restore_section_states (myDocument, section_states);
   // Export each page
   for(var i = 0; i < myDocument.pages.length; i++)
      {
      app.pdfExportPreferences.pageRange = page_ranges[i];
      myFilePath = myFolder + "/" + filename_pagenames[i] + "-" + myBaseName + ".pdf";
      myFile = new File(myFilePath);
      myDocument.exportFile(ExportFormat.pdfType, myFile, false, myPDFExportPreset);
      }
   }
else
   {
   myDialog.destroy();
   }
} 

function restore_section_states (doc, states)
{
for (var i = 0; i < doc.sections.length; i++)
   doc.sections[i].includeSectionPrefix = states[i];
} 

function strip_section (pg, array)
{
for (var i = 0; i < array.length; i++)
   if (array[i].length > 0)
      if (pg.match (RegExp ('^'+array[i])) != null)
         {
         pg = pg.replace (RegExp ('^'+array[i]), '');
         break
         }
return pg
}
