    Sorry, I need to make a change in what I wrote above. When you create the custom field, you should not select the option Required to solve a ticket.

    Thanks for sharing this Karen :)

    This is awesome!

    I've also updated your post to remove the Required to solve ticket option.

    Cheers!

    Great article, but I am having problems with the js.  I get the following error in console "startObserveMutations is not defined".

    Am I missing something?

    Hi Kevin Witt,

    Can you share a bit more detail here? Like the screen shot of the code of the URL of you HC?

    Thanks

    Sure, a configured as per the article (Except I didn't hide the checkbox at this point so I can see what is happening).

    I have a drop-down that determines if the attachment is required, with the options "Attachment not required" and "Attachment required".

    The error I see in the console is:

    The HC is in my sandbox: https://unifydemo1508140682.zendesk.com

    The form is called "Attachment Test".

    My JS is as follows:

    // Callback function to execute when mutations in form attachments or dropdown are observed:
    // clear or select Attachment checkbox according to dropdown
    var mutationObservedForm = function (mutationsList) {
    mutationsList.forEach(function (mutation) {
    if (mutation.type == 'childList') {
    setFormAttachmentCheckbox();
    }
    });
    };

    // Define some variables for requiring form attachments
    var attachmentCheckboxField = 'request_custom_fields_360003651537';
    var attachmentCheckboxId = '#' + attachmentCheckboxField;
    var attachmentErrorNotification = 'Report must be attached';
    var formDropdownClass = '.request_custom_fields_360003651357';
    var formObserveMutationOptions = { childList: true, subtree: true };

    // Clear or select checkbox according to dropdown and attachments:
    // Set Attachment checkbox if no attachments required, or if attachments are required and at least one is uploaded, otherwise clear it
    function setFormAttachmentCheckbox() {
    if (isFormAttachmentRequired()) {
    if ($('#request-attachments-pool .upload-item').length) {
    selectCheckbox(attachmentCheckboxId);
    }
    else {
    clearCheckbox(attachmentCheckboxId);
    }
    }
    else {
    selectCheckbox(attachmentCheckboxId);
    }
    }

    // Return true if dropdown option 'ABCD' is selected
    function isFormAttachmentRequired() {
    return $(formDropdownClass + ' a.nesty-input').attr('aria-expanded') &&
    $(formDropdownClass + ' a.nesty-input').text() === 'Attachment required';
    }

    // Select checkbox
    function selectCheckbox(eltselector) {
    $(eltselector).prop('checked', true);
    }

    // Clear checkbox
    function clearCheckbox(eltselector) {
    $(eltselector).prop('checked', false);
    }

    // If attachment checkbox field exists, select it,
    // and watch for changes to attachments and dropdown
    if ($(attachmentCheckboxId).length) {
    selectCheckbox(attachmentCheckboxId);
    startObserveMutations('#request-attachments-pool', formObserveMutationOptions, mutationObservedForm);
    startObserveMutations(formDropdownClass, formObserveMutationOptions, mutationObservedForm);
    }

    // Adjust attachment error notification
    var attachmentErrorElt = $('.' + attachmentCheckboxField + ' .notification-error');
    if (attachmentErrorElt.length) {
    attachmentErrorElt.text(attachmentErrorNotification);
    }

    Oops, I wrote the post above with the JS to do this, and it looks like I left out the code for the startObserveMutations function! Sorry about that, here it is:

    // Function to start observing node for mutations
    var startObserveMutations = function (nodeSelector, options, callbackFunction) {
    var node = document.querySelector(nodeSelector);
    if (node) {
       var observer = new MutationObserver(callbackFunction);
       observer.observe(node, options);
      return observer;
      }
    };

     

    Hopefully this will fix the problem.

    Kevin Witt, as Karen D Snyder mentioned, you need to write the startObserveMutations function. Also, looking at your code, you are looking for the changes in the attachment field and in your code you are observing the checkbox for changes.

    Thanks

    Glad it's working, sorry for leaving out the function in the first place!
