Upload PDF via code

Regis Wengel asked on July 16, 2019 18:20

We have a client that wants us to build a form for them. Due to several requirements we are unable to use Kentico's form builder and thus are building the form via code. We have built a Kentico form in order to hold the form data and are using BizFormItem in order to create a new record for this form.

One of the fields on this form needs to be an upload file. I have been looking through the documentation, but I'm not finding anything in regards to uploading a file that is linked (attached?) to a form record. Does Kentico have any API methods that achieve this?

This article is quite old but the concept is very similar in newer versions. You will have to check namespaces and probably a method or two have changed but should get you in the right direction.

Hey Brenden,

That was exactly what I was needing, thank you. A follow up question. I also need to attach these uploaded document to the notification email. My code looks as follows

private void SendEmail(BizFormInfo bfi, DataClassInfo dci, int id)
{
    if (!string.IsNullOrEmpty(bfi.FormSendFromEmail) && !string.IsNullOrEmpty(bfi.FormSendToEmail))
    {
        bfi.FormEmailAttachUploadedDocs = true;

        BizForm f = new BizForm();

        IDataClass content = DataClassFactory.NewDataClass(dci.ClassName, id);

        f.SendNotificationEmail(
            bfi.FormSendFromEmail,
            bfi.FormSendToEmail,
            content, bfi);
    }
}

The email sends fine, however the documents don't get attached. Taking a look at CMS.OnlineForms.Web.UI.dll I found the SendNotificationEmail method.

public virtual void SendNotificationEmail(string fromEmail, string recipients, IDataContainer data, BizFormInfo bfi) {
...
if (bfi.FormEmailAttachUploadedDocs)
            {
                string bizFormFilesFolderPath = FormHelper.GetBizFormFilesFolderPath(base.SiteName, null);
                foreach (string uploadFile in this.uploadFiles)
                {
                    string str2 = Convert.ToString(data.GetValue(uploadFile));
                    if (string.IsNullOrEmpty(str2))
                    {
                        continue;
                    }
                    string str3 = string.Concat(bizFormFilesFolderPath, FormHelper.GetGuidFileName(str2));
                    if (!File.Exists(str3))
                    {
                        continue;
                    }
                    Attachment attachment = new Attachment(FileStream.New(str3, FileMode.Open, FileAccess.Read), this.GetFileNameForUploader(str2));
                    emailMessage.Attachments.Add(attachment);
                }
            }

...
}

I can't debug the dll, but my best guess is that this.uploadFiles isn't returning anything. Currently I'm saving the file to FormHelper.GetBizFormFilesFolderPath(SiteContext.CurrentSiteName); and then saving the string reference (<GUID>.<extension>/<orig_name>.<extension>) to the form. I'm guessing though that Kentico doesn't know I want to link a file to a form. Is there a method to achieve this?
