1. *Create controller and model:*
The controller and model to use depend on the table the languages are stored
in. For example if the languages are in a table called "languages", then
create a model named Language and a controller named LanguagesController.
2. *Create an action that returns the list of languages *
In LanguagesController, create an action called getLanguages for example.
Basically what it does is query the languages table (
$results=$this->Language->find('all'); )
and then it returns the result ( return $results; )
3.*Create an element (for example call it language_list.ctp)*
First retrieve the information using requestAction
(for example: $languages=$this->requestAction('languages/getLanguages') )
Then create the html needed for the languages
(for example: foreach($languages as $language){ //html here }
4.*Call the element from the default.ctp layout*
* *echo $this->element('language_list');
Now usually I wouldn't use requestAction as it would hit my performance, but
since the list of languages is part of the layout, I think it would be the
safest way to go.
In order to fix the performance costs of requestAction, I would recommend
the use of caching (especially that these languages will probably not change
very often)
You can for example cache the element i.e:
you can can add a parameter to the element call from default.ctp:
echo $this->element('language_list',array('cache'=>array('time'=>'+1
week','key'=>'languages')));
That is how I would do it. I'm sure there are other (and maybe better)
solutions, but this would definitely work.
