Enum: validation

[Ali1]

$this->enum is a pretty good method to get an array of enum key-value pairs but a method to use in $validate may also be handy. See example:

    public $validate = array(
        'country' => array(
            'checkEnum' => array(
                'rule'     => array('validateEnum'),
                'message'  => 'Please enter a valid country'
            ),
    );

Feel free to use this method which is working well for me.

    public function validateEnum($check){
        $field=key($check);
        $value=$check[$field];
        $values=$this->enum($field);
        if(empty($values)) return false;
        if(isset($values[$value])) return true;
        else return false;
    }

Useful when 'Security' component is turned off.

Tweaked to allowEmpty fields, however I'm sure there is a better way to do this which relies on 'notEmpty'=> true ?

    public function validateEnum($check,$allowEmpty=false){
        $field=key($check);
        $value=$check[$field];
        if($allowEmpty && empty($value)) return true;
        elseif(empty($value)) return false;
        $values=$this->enum($field);
        if(empty($values)) return false;
        if(isset($values[$value])) return true;
        else return false;
    }

Here we go!

    public function validateEnum($check,$rule){
        $field=key($check);
        $value=$check[$field];
        if(!$rule['notEmpty'] && empty($value)){
            return true; 
        }elseif(empty($value)){
            return false;
        }
        $values=$this->enum($field);
        if(empty($values)){
            return false;
        }
        if(isset($values[$value])){
            return true;
        }
        return false;
    }

So 'rule' => array('validateEnum') actually triggers the behavior method? Cool.

Don't see no reason against implementing this.

Exactly. I'm using it now and it's working perfectly.

Added but had to change it slightly.
