Divergent recipients depending select box value
A select box with options 0/1 decide, who will receive the mail. Option 0 will send the mail to the default recipient, option 1 will be caught by the following condition:
# Condition for TYPO3 before 9.5
[globalVar = GP:tx_fluidform_form|form-footer-complete-customer = 1]
plugin.tx_fluidform.settings.forms.callBack.finisher.mail.to.0.email = info@test.de
[global]
# Condition since TYPO3 9.5
[traverse(request.getParsedBody(), 'tx_fluidform_form/form-footer-complete-customer') == 1]
plugin.tx_fluidform.settings.forms.callBack.finisher.mail.to.0.email = info@test.de
[end]
You can use other values or alternative TypoScript conditions as well.
Attention:
It might be, that your Mailhog only displays emails only unique, if you try to create an additional receiver with this logic.
