How was the form hacked in yii?

Question

Yii

In general, there is a form with 3 fields, I enter data, I press send, I look in the database it saves not at all. Dumped before the save method and after, the necessary data lies, the core of the framework re-uploaded the same. Where could there be a hole?

In general, there is a car with 4 wheels, I insert the key, open the door, look into the salon, it’s not the same at all. I checked the parking lot: the one under the house, the engine is the same. Where could be the problem?
It can be anything, for example, the behavior of a model, or a form, or something else. Studio code
