[FIXED] How do I validate multiple fields from a single location in CakePHP?

Issue

I wanna validate multiple fields at one place. So in a form I have included 4 fields as follows

1. facebook_link
2. twitter_link
3. google_plus_link
4. linked_in_link

The user atleast type any one field of above. Please help me to get the solution like, the user types anyone of the links in the form.

Solution

you may add your own Validation Methods.

public $validate = array(
    'facebook_link' => array(
        'rule'    => array('validateLink'),
        'message' => '...'
    ),
    'twitter_link' => array(
        'rule'    => array('validateLink'),
        'message' => '...'
    ),
    'google_plus_link' => array(
        'rule'    => array('validateLink'),
        'message' => '...'
    ),
    'linked_in_link' => array(
        'rule'    => array('validateLink'),
        'message' => '...'
    ),
);

public function validateLink($link) {
    $allFieldsAreEmpty = (
        empty($this->data[$this->alias]['facebook_link']) &&
        empty($this->data[$this->alias]['twitter_link']) &&
        empty($this->data[$this->alias]['google_plus_link']) &&
        empty($this->data[$this->alias]['linked_in_link'])
    );

    return !$allFieldsAreEmpty;
}
