Hi there I would like to rename images and videos uploaded from a front end submission to be prefix the name with a custom field value (also present on the form). Can you please advice how I could do this? Ideally I was looking for filter prior to upload so i can rename the file but cant seem to find one. Please help
You can try to use the field type file and use the setting unique_filename_callback to modify the file name before saving it to the database. Please read more on the documentation https://docs.metabox.io/fields/file/
.
