# Auto Triggering OG Image Update

There are times you need to update something that will directly effect the generated open graph image. For an example you have a post where you are adding the post title to the OG image. When the title gets updated, you will want the OG image to be updated as well.\
\
To automatically trigger the update of OG images on such occasions, you may add a property to your model as below.

```php
protected array $graphify_fields = [
    'title',
];
```

This will auto update the OG image  when the title of the model is updated.
