Hi,

I have a custom handler for form submission to handle custom submission to a web service, but I have no idea how to get all the uploaded files from the form BizFormItem field.

Its a little old but... This may help you

string fileNameString = "605b0932-660c-43cf-b2e0-b5ccf519f75f.png/originalFileName.png";

BasicForm bf = new BasicForm();

string fileName = bf.GetGuidFileName(fileNameString);
string filePath = FormHelper.GetBizFormFilesFolderPath(CMSContext.CurrentSiteName) + fileName;

if (File.Exists(filePath))
{
FileStream stream = new FileStream(filePath, FileMode.Open, FileAccess.Read);

// Add attachment
Attachment attachment = new Attachment(stream, bf.GetFileNameForUploader(fileNameString));
}

You should be able to pull the file name or a GUID from the form data

We are on Kentico 9, bz.GetGuidFileName() doesn't exist anymore neither does FormHelper.GetBizFormFilesFolderPath(). Is there any example how to read an uploaded file from a BizForm in Kentico 9 ?

Looks like you need to use CMS.OnlineForms now See the OnlineForms API reference here You might be able to use something like BizFormItem.GetExternalPath

There are some API examples here that might help

BizFormItem.GetExternalPath is a protected method of the BizFormItem class. Is there any other way ?
