Working with incomplete information here... Single input, multiple values. I do not understand why? There are so many resources available for you to permit users to enter multiple and distinct emails values.
The following is crude, but I think that it may be helpful.... Well as far as I know you can't use ActionView::Helpers::FormHelper : http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#method-i-email_field email_field(object_name, method, options = {}) >From the browser instance, you can introduce an onChange event on your multiple value email field with JQuery/JavaScript: making a call to something like (just offered as psuedo code): var my_failed_email_address = Array // outside of the function, maybe function validEmail(multiple_email_element_by_id) var emailRegex = /^[a-zA-Z0-9.!#$%&'*+\/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$/; /// Someone can probably suggest a better reg exp Use Jquery to split the multiple_email_element_by_id field value by your required delimiter(s) and put it into an array... var my_email_address = Array // Use the above to populate the array For each element in resulting array if (!( emailRegex.test(increment value) ) ) return true // maybe just return the empty array else my_failed_email_address.push(that element) // Otherwise add new value to array return false // maybe just return pupulated array end end If this returns false, then you have numerous options: you can inform the user of failed email address(es) with an alert, populate some html span/error associated with the email input with meaningful error message, or change the css on the email input.... Or you can use validation in the Controller or Model in a similar fashion In the Controller, parse the multiple email field from params and write a method to test for validity of each. If failure turn to originating render In the model, make accessible your multiple_email field, and write call back to parse the field for validation. On failure, inform user at View level with if model.errors.any?
