Sounds like a perfect candidate for a behaviour to me. It's not
applicable to all models, you wouldn't want your User or Group model
to be checked, and perhaps you have different field names in different
models that need checking, these would go in the config array.
here;s an idea:
var $actsAs = array(
'Cleanup'=>array('body')
);
class CleanupBehavior extends ModelBehavior
{
/**
* Contain settings indexed by model name.
*
* @var array
* @access private
*/
var $__settings = array();
/**
* setups the behaviour
*
* @param object &$model the model that the behaviour is called from
* @param array $settings the settings array defined in the model
*/
function setup(&$Model, $settings = array())
{
if (!isset($this->__settings[$Model->alias]))
{
if (!empty($settings))
{
foreach($settings as $field=>$options)
{
$this->__settings[$Model->alias][$field] = am($this->__default, $options);
}
}
}
}
/**
* beforeSave callback
*
*/
function beforeSave(&$Model)
{
foreach($this->__settings[$Model->alias] as $field => $options)
{
if(isset($Model->data[$Model->alias][$field]))
{
// clean data - obviously does nothing at the
mo!
$Model->data[$Model->name][$field] =
$Model->data[$Model->name][$field];
}
}
return parent::beforeSave($Model);
}
}
