    }
}

As you can see this page is fetching MySQL data from a CUSTOM MySQL table created by me. Here is the structure of the table named VivasIndustries_SmsNotification:

I have two question about the problem:

1. Why i get the error when i click on Create new SMS Rules and how i can make a page there that have two simple imputs like: Receiver where you can place the name and Phone and then when you click Submit this data should be imported into VivasIndustries_SmsNotification MySQL table.
2. My second question is: Why when i click on a table row NO "Edit" page is opened. How i can make a simple edit page which will obviously edit the row ?

Thanks in advance!

Answer 1

Regarding the button, your error page shows that it has an action of "new", but you don't have "newAction" method in your controller. Regarding edit, you will also want "editAction" in your controller.

Wanted to add this as a comment, but needed 50 rep for that!
