Adding save pdf option GAS - google-apps-script

Question

A year ago with the help of another user I was able to use google app script to take the form responses and email a pdf (code below)
I now need to save the pdf to a specific folder
I also need to add a link to the saved pdf within the google sheet. Is this possible?
var docTemplate = "doc ID";
var docName = "Vehicle check with images";
function onFormSubmit(e) {
var replaceTextToImage = function(body, searchText, fileId) {
var width = 300; // Please set this.
var blob = DriveApp.getFileById(fileId).getBlob();
var r = body.findText(searchText).getElement();
r.asText().setText("");
var img = r.getParent().asParagraph().insertInlineImage(0, blob);
var w = img.getWidth();
var h = img.getHeight();
img.setWidth(width);
img.setHeight(width * h / w);
}
//Get information from form and set as variables
var email_address = "myemailaddress#here.com";
var vehicle_vrn = e.values[1];
var front_desc = e.values[2];
var front_image = e.values[3].split("=")[1];
var rear_desc = e.values[4];
var rear_image = e.values[5].split("=")[1];
var driver_desc = e.values[6];
var driver_image = e.values[7].split("=")[1];
var passenger_desc = e.values[8];
var passenger_image = e.values[9].split("=")[1];
// Get document template, copy it as a new temp doc, and save the Doc’s id
var copyId = DriveApp.getFileById(docTemplate)
.makeCopy(docName+' for '+vehicle_vrn)
.getId();
// Open the temporary document
var copyDoc = DocumentApp.openById(copyId);
// Get the document’s body section
var copyBody = copyDoc.getBody();
copyBody.replaceText('keyVrn', vehicle_vrn);
copyBody.replaceText('keyFrontdesc', front_desc);
replaceTextToImage(copyBody, 'keyFrontimage', front_image);
copyBody.replaceText('keyReardesc', rear_desc);
replaceTextToImage(copyBody, 'keyRearimage', rear_image);
copyBody.replaceText('keyDriversdesc', driver_desc);
replaceTextToImage(copyBody, 'keyDriversimage', driver_image);
copyBody.replaceText('keyPassdesc', passenger_desc);
replaceTextToImage(copyBody, 'keyPassimage', passenger_image);
copyDoc.saveAndClose();
var pdf = DriveApp.getFileById(copyId).getAs("application/pdf");
var subject = "sample attachment file";
var body = "sample text: " + vehicle_vrn + "";
MailApp.sendEmail(email_address, subject, body, {htmlBody: body, attachments: pdf});
DriveApp.getFileById(copyId).setTrashed(true);
}```

Answer 1

I believe your goal as follows.
You want to save the PDF data to the specific folder as a file.
You want to retrieve the URL of the saved PDF file and put it to the specific column of the Spreadsheet.
Modification points:
In order to save the PDF data (in your case, it's a blob.) to the specific folder, you can use DriveApp.getFolderById("folderId").createFile(pdf).
In order to retrieve the URL of the created file, you can use getUrl().
In order to put the URL to the specific column of the Spreadsheet.
You want to put the value to the next column of the last row.
Modified script:
Please modify your script as follows. Before you use this modified script, please set the folder ID, Spreadsheet ID and sheet name.
From:
copyDoc.saveAndClose();
var pdf = DriveApp.getFileById(copyId).getAs("application/pdf");
To:
copyDoc.saveAndClose();
var pdf = DriveApp.getFileById(copyId).getAs("application/pdf");
var url = DriveApp.getFolderById("###folderId###").createFile(pdf).getUrl();
var sheet = SpreadsheetApp.openById("###spreadsheetId###").getSheetByName("###sheetName###");
sheet.getRange(sheet.getLastRow(), sheet.getLastColumn() + 1).setValue(url);
When you run the script, pdf is created to the folder ###folderId### as a file, and url is put to the next column of the last row of the sheet ###sheetName### on the Spreadsheet ###spreadsheetId###.
Note:
If you want to give the filename of PDF file, please modify as follows.
From
var pdf = DriveApp.getFileById(copyId).getAs("application/pdf");
To
var pdf = DriveApp.getFileById(copyId).getAs("application/pdf").setName("###filename###");
References:
getFolderById(id)
getUrl()
getRange(row, column)
