Yii. How to pass data from database to layout?

Question

Yii

The layout has a certain block that should be on every page. It is filled with data from the database. Own question. What is the best way to do this?

Answer 1

Controller variables are available in layout. Make an assignment in the controller and echo $this->var in the layout. If necessary on all pages, we accordingly make an assignment in the controller, from which all the rest are inherited

Answer 2

DAO or AR depends on the data itself.

Answer 3

disassemble any application in yii, read the documentation, manual, writing a blog on offsite - data transfer to a view is used everywhere.
