Gravity Forms, a popular WordPress form plugin, has recently encountered an issue with its API version 2 form submissions. Users have reported that forms are not being submitted successfully, resulting in lost data and incomplete transactions.
Cause of the Issue
The issue stems from a change in the way Gravity Forms handles form submission data in API version 2. Specifically, the plugin now requires the use of a multipart/form-data content type for file uploads. However, some API clients may not be sending the data in this format, leading to submission failures.
Impact of the Issue
The issue affects all forms that use file upload fields and are submitted via the Gravity Forms API version 2. Common scenarios include:
- File upload forms for product submissions
- Application forms with resume or portfolio attachment requirements
- Forms for image or video submissions
Solution
To resolve the issue, API clients must ensure that they send file upload data in the multipart/form-data content type. This can be done by using a multipart/form-data encoder on the client-side.
Temporary Workaround
If updating the API client is not immediately possible, a temporary workaround is to disable the file upload fields from the affected forms. However, this may not be a suitable solution in all cases.
Gravity Forms Response
Gravity Forms has acknowledged the issue and is working on a fix. In the meantime, the team recommends using the following workaround:
- Open the affected form in the Gravity Forms editor.
- Under the “Settings” tab, click on “Form Editor.”
- Find the file upload field and disable it by setting the “Enabled” option to “No.”
- Save the form.
