Overcome the problems of adding, deleting, and modifying CakePHP series three-form data

The following code adds, deletes, and modifies form data in CakePHP. here we declare a point. in the previous example, we accidentally typed the lastupd field in the database table into lastudp. In this example, we will correct it.

Except for the appeal field, the database is consistent with the previous example.

The project still follows the example above, for example:

The code is as follows:

Database. php: same as the previous example.
