Sending variables from the controller to the view

A common task in MVC programming is the concept of setting variables from a controller to a view. In concrete5, blocks follow the same principles. Fortunately, setting variables to the view is quite easy.

Getting ready

This recipe will use the block type that was created in the first recipe of this chapter. Feel free to adapt this code to work in any block controller, though.

How to do it...

In your block's controller, use the set() function of the controller class to send a variable and a value to the view. Note that the view doesn't necessarily have to be the view.php template of your block. You can send variables to add.php and edit.php as well. In this recipe, we will send a variable to view.php. The steps are as follows:

Open your block's controller.php file.
Add a function called view() if it doesn't already exist:
```
public function view() {
}
```
Set a variable called name to the view.
```
$this->set('name', 'John Doe');
```
Open view.php in your block's directory.

Output the value of the name variable.

<div class="content">
  <?php echo $name ?>
</div>
