Now let us go back to editing that functionality there, and show some more options('Look'). Go to custom buttons. Add another button. Target - call it 'single'. Name - call it 'Work'. The Controller method - 'getDone', and leave Type to 'Default' and then save.

In the(PHP controller method) a public function is placed. This time we will get the model and do something in the model. You can also get the item values. When this button is clicked, the item opens and it automatically submit the form. It is possible to grab the item's values but the values may differ from those in the database.

Yet those values have not been saved to the database. If those values need to be in the database, you have to put it there. I'm not going to demonstrate how to do that. The model has a save method, and you should do the necessary sanitation, and trigger the save method, and it should store the data. For this purpose the data need to be grabbed, a verification be done, and then return either an error or a success. <<<<<<<<<<<<<<<<<<<<<

I'm just going to grab the data. I'm just going to do a little verification maybe, and then return back either an error or a success.
### Checking Within Controller Before Trigger The Model

First we going get the values. We have the data, we can check whether the values that we want to use is there and available. We want to make sure that this is already a saved item.

We need to have a name, and then we can check for that. We can do some checking within the controller before we trigger the model, and run the function we intend. Then we triggered the model, we decide what we want to call a method in the model. I chose something random and then we can create that method in the model area. And then do whatever we want to do.
### Logic In The Model Methods
