TYPO3 Core

Example form. There is a breakOnError option to demonstrate that the wizard does not touch it during a save process:

enctype = multipart/form-data
method = post
novalidate = novalidate
prefix = tx_form
confirmation = 1
postProcessor {
    1 = mail
    1 {
        recipientEmail = your@mail.com
        senderEmail = your@mail.com
    }
}
10 = TEXTLINE
10 {
    type = text
    class = hasClass
    id = hasId
    autocomplete = on
    name = surname
    placeholder = Surname
    required = required
    label {
        value = Surname
    }
}
20 = SUBMIT
20 {
    type = submit
    class = hasClass
    id = hasId1
    name = 3
    value = Submit form
}
rules {
    1 = required
    1 {
        breakOnError = 1
        showMessage = 1
        message = Required
        error = This field is required
        element = surname
    }
}
