CakePHP where can I put this code for reuse?

I have a model called PageMetaData that contains a title and a description. This is to be tied to any other model and to be used as the title tag and meta description for the page.

So I have a model called Brand. Brand has a field called page_meta_data_id and Brand belongsTo PageMetaData

Now on the view for Brand I can run this code:

if(!empty($data['PageMetaData']['title']))
{
    $this->set('title_for_layout', $data['PageMetaData']['title']);
}
else if(!empty($data['Brand']['name']))
{
    $this->set('title_for_layout', $data['Brand']['name']);
}
if(!empty($data['PageMetaData']['description']))
{
    echo $this->Html->meta('description', $data['PageMetaData']['description'],array('inline'=>false));
}
else if(!empty($data['Brand']['description']))
{
    echo $this->Html->meta('description', $data['Brand']['description'],array('inline'=>false));
}

And if a PageMetaData has been associated to the current Brand and has a value for title, it will set that as the page title, otherwise if the brand has a field called name it will us that. Same for description.

The problem is I don't want to have to diplicate this code in every view for every model that uses PageMetaData.

I cannot figure out where I can abstract the code to, to avoid duplication.

I cannot put it in a Behavior or a Helper because you cannot set the title from either. I cannot put it in a Component because it cannot access the data found from the model.

Is there somewhere I can put this code for reuse?

Place the method in your AppModel. I assume the method accepts an id for it to return the appropriate data.

Place another method in your AppController's beforeRender method. Pass the id to this method; which in turn will call the method in AppModel; setting title_for_layout, meta_description and keywords.

You should also not echo out these values, but rather pass them to the view and output them there (or in the layout).

AppController and AppModels are application-wide; so any controller/model may access the methods.

I'm sure there's other methods; and this might not work as I haven't tested it.

You can possibly use elements for this. have a look at the cookbook link:
