This morning I released beta-2 of WordPress Google Form v0.59. This build introduces one new feature (hidden fields) and fixes one limitation (validation rules).
Much like validation rules and placeholders, an input field can now be defined as hidden. When a field is defined as hidden, it does not appear to the user when they view the form and the value is set to a fixed value (e.g. a static string) or to something WordPress derives (e.g. the user’s IP address).
The format of the field name is exactly the same as used for validation and placeholders.
Validation has been improved and the limitation of one validation rule per field has been lifted. You can now define multiple validation rules for a single field. Simply enter the field name for each separate type of validation.Google Forms Beta (864 downloads)
