Filter's dont work

so it's no possible write only one row for every controller's method  ? In ci3 i insert the control in constructor ( control if isset a session variable) but seem not working in ci4

As I understand it you are asking two questions:
1) one row for each controller method?
Yes, you can do:

PHP Code:

$routes->post('example', 'Controller\example'); 


2) control in constructor in CI4
I understand the pain - in CI3 I used the constructor to check for access and bailed out if no access.
For CI4 you should look into Controller before Filters instead - https://codeigniter4.github.io/userguide...re-filters
Also, in CI4, the constructor of a controller is replaced with initController - https://codeigniter4.github.io/userguide...oller.html
