there is no problem to prefill normal fields, but i am not able to prefill one or more checkboxes neither with typoscript nor via GET-Parameter.
i tried:
GET-Parameter:
&tx_powermail_pi1[field][marker][0]=1
&tx_powermail_pi1[field][marker][0]=1
Typoscript:
marker = TEXT
marker.value = 1
marker.0 = TEXT
marker.0.value = 1
is there a passibility to prefill /preselect a checkbox?
Thanks!
