Our customer uses a TYPO3 6.2.14 and built a formular with formhandler(2.0.1). Now we have to add a captcha to prevent spambots to post. So I installed captcha(1.3.0) as recommended in the documentation and added the following lines of typoscript (validation part only):
plugin.Tx_Formhandler.settings.predef.contact_test {
# ...
validators{
# default validator
1 {
class = Validator_Default
config {
disableErrorCheckFields = captchafield
fieldConf {
salutation.errorCheck.1 = required
firstname.errorCheck.1 = required
lastname.errorCheck.1 = required
email.errorCheck.1 = required
email.errorCheck.2 = email
subject.errorCheck.1 = required
message.errorCheck.1 = required
}
}
}
# captcha validate
2 {
class = Tx_Formhandler_Validator_Default
config {
disableErrorCheckFields = salutation,firstname,lastname,email,subject,message
fieldConf {
captchafield.errorCheck.1 = captcha
}
}
}
}
# ...
}
The required fields still works like before and also the captcha field reacts to a non-filled state and abbort the submission if the captcha is wrong. But why it doesn't show up an error like "Your entered captcha doesn't match"?
I just need to add the captchafield.errorCheck.1 = captcha to the default validator. The reason for the empty error messages was the not cleared install tool cache. The language xml Files containing some outputs are cached by default.
