CakePHP MySQL选择每月的一天

Question

I hope to write correctly because I'm not very good in English. I would select only the day of the month from MySQL but writes me an error.

CONTROLLER

$fields = array('id', 'nazov','DAY(datum) AS day','datum');
$data = $this->udalost->find('all',array('conditions'=>'MONTH(datum) = '.$month.' AND YEAR(datum) = '.$year,'fields'=>$fields,'order'=>'datum ASC'));
$this->set('data',$data);

VIEW

echo $data["day"];

ERROR

Notice (8): Undefined index: day [APP\views\udalosti\calendar.ctp, line 4]

MySQL

CREATE TABLE `udalost` (
  `id` INT(11) NOT NULL AUTO_INCREMENT,
  `nazov` VARCHAR(255) DEFAULT NULL,
  `datum` datetime DEFAULT NULL,
  `text` text,
  `created` datetime DEFAULT NULL,
  `modified` datetime DEFAULT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM

Can you tell me where I have error?

Answer 1

Try to debug $data in your view:

debug($data);

If you call the find method, you'll usually get a multi dimensional array.

Also write the condition like this:

$data = $this->udalost->find('all',
    array(
        'conditions'=> array(
            'MONTH(datum) = '.$month,
            'YEAR(datum) = '.$year
        ),
        'fields'=>$fields,
        'order'=>'datum ASC'
     )
);

Good luck!

Answer 2

You do not have the index 'den', but you try to use it. (calendar.ctp, line 4).
