I am using

“slim/csrf”: “~0.8.3” and “slim/slim”: “~3.12.3” and my custom twig function for this

> <https://github.com/flextype-plugins/twig/blob/master/twig/CsrfTwigExtension.php>

I am trying to understand why values are empty on my page

```auto
<input type="hidden" name="csrf_name" value="">
<input type="hidden" name="csrf_value" value="">

```

Session was started in the app but this values are empty for some reason.  
Any ideas ?

this method returns **null**

but why ?

```auto
    /**
     * @return string
     */
    public function getTokenName()
    {
        return isset($this->keyPair[$this->getTokenNameKey()]) ? $this->keyPair[$this->getTokenNameKey()] : null;
    }

    /**
     * @return string
     */
    public function getTokenValue()
    {
        return isset($this->keyPair[$this->getTokenValueKey()]) ? $this->keyPair[$this->getTokenValueKey()] : null;
    }

```
