    Google Script doPost(): Get the full link (URL path) to the image

    Asked by hartgen on January 13, 2015 at 11:16 AM

    Dear all,

    I created a form that uses the "take photo" widget, which works pretty well: http://form.jotformpro.com/form/50122342701943

    With submission I'm posting all data to a Google apps script (by "doPost" method)

    Unfortunately the image will be postet only by ist filename "image.jpg".

    There is also a connection from the form to a Google spreadsheet. In the spreadsheet the collumn for the image has the value http://www.jotformpro.com/uploads/hartgen/50122342701943/296973945556506478/image.jpg.

    So there is the correct link in the spreadsheet.

    How can I implement to send the complete link of the image (like in the spreadsheet) by "doPost"?

    Best regards

    After several testing the Image link is not sent at all any more. In the widget "take photo" it's not possible to find out the Name of the field containing the Image, because the Name is not listed in the properties of the field.

    Hi Jorg,

    You re only sent the name of the file and not the entire link over the POST setup.

    Now it is still easy to get the image shown to you following few simple steps:


    You can see it in action based on the link you have given:


    Now it is important to know that the username and form ID is something that you know as soon as you create the jotform and as such can implement into the script right away.

    The second part is more interesting:


    Both of them are sent to you within the POST data and as such you can get them like so (in PHP):

    $_POST['submission_id'] and


    What this means is that you can create the a (link) element and set its href attribute using the link built in the manner mentioned above.

    Do let us know if that helps you.

    Best Regards,

    Hi Ben,

    we're getting near to it, but haven't reached the goal:


    submission_id: Has been posted

    file_upload_field_name: Seems not to be postet. I get an "undefined".


    Here is my code from google apps:

    belegurl is the var that should show the correct url of the uploaded file. But it doesn't.

    Could you please help?



    // Rechnungsmail erzeugen


    function doPost(e) {


      var parameter

      var wert


      for (var i in e.parameters) {

        parameter = i;

        wert =  e.parameters[i];


        if (parameter == "belegdatei") {var belegdatei = wert;}

        if (parameter == "rechnungsnummer") {var rechnungsnummer = wert;}

        if (parameter == "ihrekundennummer") {var ihrekundennummer = wert;}

        if (parameter == "rechnungsdatum") {var rechnungsdatum = wert;}

        if (parameter == "rechnungsbetragbrutto") {var rechnungsbetragbrutto = wert;}

        if (parameter == "emailbeleg") {var emailbeleg = wert;}

        if (parameter == "feedbacktext") {var feedbacktext = wert;}

        if (parameter == "emailfeedback") {var emailfeedback = wert;}

        if (parameter == "submission_id") {var submission_id = wert;}

        if (parameter == "file_upload_field_name") {var file_upload_field_name = wert;}



        //Weitere Variablen bilden

        var AdditionalEmailAdresses = "joerg.hartgen@googlemail.com"; //, hartgen@energieautonom.de";

        var EmailEmpfaengerliste = emailbeleg + ", " + AdditionalEmailAdresses;


       //Bild der Rechnung herunterladen

       var belegurl = "http://www.jotformpro.com/uploads/hartgen/50122342701943/" + submission_id + "/" + file_upload_field_name;


      return HtmlService.createHtmlOutput("Beleg-Url: " + belegurl);

    Hi Jorg,

    This is my fault, I do apologize for this. I wanted to add that "file_upload_field_name" is the name of the field on your jotform that you are sending the data from, seems that I did not do so.

    In your case this would be belegdatei.

    In the end it should like like this: http://pastebin.com/XTqfQqMU

    Do let us know how it goes and once again I apologize for not giving more details in my previous response in regards to the field name.

    Best Regards,
