typo3 extbase: validate a form
I created a simple "subscribe to newsletter" form: <f:form action="subscribe" method="post" name="newsletterform"> <f:form.textfield id="name" name="name" required="true" /> <f:form.textfield id="email" name="email" required="true"/> <button type="submit">Submit</button> </f:form> as you can see, this is not a form that's based on an existing model, I have no interest in saving newslettersubscriptions to the database (they'll be stored somewhere else anyways). Now in my subscripeAction I want to do some form validating. I want to check if the email is really an email address, if its notEmpty
