How to create a hidden field using the hidden field function

Added for version: 0.4

To add hidden data to your form use the hidden-field function.

The hidden-field function should be used only inside forms. Otherwise, you may not be able to capture the data later.

Hidden-field takes a record, the name of the record, the key in record to get the value from, and optional html-options.

To create a hidden field for a :message record with value “Blah” associated with key :text use:

(hidden-field { :text "Blah" } :message :text)

The above link passes the map { :text “Blah” } as the record to use. More likely, the record you use comes from your database or other model.

The name of the hidden input tag created by hidden-field is “message[text]”, its id is “message-text”, and its value is “Blah”.

You can pass html-options to add attributes to the input tag. To set the hidden field’s id use:

(text-field { :text "Blah" } :message :text { :id "hidden" })
