File Upload

The file upload field allows users to upload one or more files. This can be used for attachments, but also for taking and attaching a photo on a mobile device, for example.
Supported file types can be previewed directly in the browser using the eye icon ().

Configuration​

The following options are available in the configuration:

  • Title:
    Enter the display name of the control element here. This is displayed to the users so that they know which control it is.
  • Internal name:
    The internal name allows you to reference a control in placeholders or rules using a name other than the title. This field does not have to be filled in, but is helpful if you have several controls with the same title in a form.
  • Mandatory field:
    If you activate this option, people must fill in this field before the form can be transferred to the next process step via a button. In this way, you can force a form to have all the necessary information before it is sent.
    Caching is possible at any time, even if mandatory fields are not filled in.
  • Exclude from PDF export:
    The standard PDF export exports all control elements in the form. If you activate this option, the element is not included in the standard PDF export.
    The control element can still be used manually in a document template.
  • Maximum file size:
    You can use this option to determine the maximum size of a single uploaded file.
    In this way, you can ensure that users upload files that are easy to work with.
  • Allowed file types:
    You can enter comma-separated file extensions here to restrict the possible file types. If you do not enter a value here, all file types can be uploaded.
  • Default value:
    Here you can specify the files that are initially present in the control by default. These are copied when saved to ensure revision security.
    This can be used, for example, to transfer files from a previous step.
  • Editing tools:
    Here you can specify whether certain file types can be edited directly in the browser. For example, users do not have to download and upload a PDF file first in order to add small annotations.
  • Help text:
    If you enter a value here, a help icon () is displayed next to the control. People can click on this to display the help text. This allows you to give people help on an individual control.

Placeholder​

This control makes the uploaded files available as placeholders. You can choose between different formats:

  • Comma separated file names:
    This format lists the names of the uploaded files separated by commas.
  • Clickable file list:
    This format lists all files as links, allowing users to click on them to download or, if supported, preview them in the browser.
  • Clickable file list (without preview):
    This format lists all files as links that always trigger a download, even if the file could be viewed in the browser.
  • Picture:
    This format only includes image files. Images are directly embedded and displayed. This can be especially useful, for example, in combination with a PDF export.
