[Solved] Can't use method return value in write context

[eluser]Tpojka[/eluser]
Few things before trying to solve:
1. method has no name;
2. model as represented has no that line

First block of code, if controller, has no name of method.
Error that is displayed tells that something is wrong in model.
And in Model there is no that line, so can you put things together again, please?

Also try to check if post data is opposite to FALSE. Maybe you get something.
