Summary

Creating Form and their related InputFilter classes in an Admin project adds a default CsrfInput to both elements, however the input name is capitalised in inputFilters and not in forms, resulting in validation errors if not caught.

// EditBookInputFilter
->add(new CsrfInput('EditBookCsrf', true));

// EditBookForm
$this->add((new Csrf('editBookCsrf'));
