Validating for both models desired

An actual version of this problem can be found here

Did you tryed to add JS code to submit both forms?

No. All code being involved has been shown up!

A general help is the following section of the guide:

Guide > Getting Data from Users > Getting Data for Multiple Models

http://www.yiiframework.com/doc-2.0/guide-input-multiple-models.html

The opening "<?=" in the first line seems to have the corresponding closing "?>" in the wrong place.

BTW, you have to try to write a well formatted code.

Reading a bad formatted code is a torture to me. ;)

Guide u noticed 'caused problems in another way(see this). So, this thread is obsolet by now!
