Hi, more recently I started to deal with CakePHP, I’m writing a function to add a material with a modal form (PopUP - a flashing window) to the database, I registered a function that should keep all the contained forms in the database, but when I refresh the page I get an error `Call to undefined function is ()`, tell me, please, where I made a mistake when writing functions. Listing of the function I am attaching:  
public function index() {  
// debug($this-\>request-\>data);  
if ($this-\>request-is(‘post’)){  
$this-\>Tets-\>create();  
if($this-\>Test-\>save($this-\>request-\>data)){  
$this-\>Session-\>setFlash(‘Good’);  
$this-\>redirect([‘action’ =\> ‘index’]);  
} else{  
$this-\>Session-\>setFlash(‘Error’);  
}  
}

```
    }
```

> if ($this-\>request-is(‘post’)){

you have minus (-) instead of object operator (-\>)
