CakePHP: Export / Download Database Code

   * Dumps the MySQL database that this controller's model is attached to.
   * This action will serve the sql file as a download so that the user can save the backup to their local computer.
   * @param string $tables Comma separated list of tables you want to download, or '*' if you want to download them all.

CakePHP: COUNT data and GROUP BY date

Goal: Count Tip Offs created per day for a month to use for graph
Problem: created field name is in datetime format: Y-m-d H:i:s
Solution: format SQL Query date: DATE_FORMAT(TipOff.created, '%Y-%m-%d')

Inside the function of controller
<?php$tipOffsMonthly=$this->TipOff->find('all', array('conditions'=>array('AND'=>array('TipOff.electric_cooperatives_id'=>AuthComponent::User('electric_cooperatives_id'), 'TipOff.created BETWEEN ? AND ?'=>array($first_day, $last_day))), 'fields'=>array("COUNT('created') as per_day", 'created'), 'group'=>array("DATE_FORMAT(TipOff.created, '%Y-%m-%d')") ));?>

CakePHP: Calling function from other controller

Import Controller of the function you want to use.

Once you imported  the controller you can call any function of this controller.

<?php//Import controller  App::import('Controller','SmsOutgoings');class ReportsController extends AppController {publicfunctionadd(){$message="Notification: New report submitted!";//Instantiation$SmsOutgoings=new SmsOutgoingsController;//Call a method from SmsOutgoingsControllerwith parameter$SmsOutgoings->notify_user($user_id,$message);}}?> Other way is by using the requestAction() function
<?phpclass ReportsController extends AppController {publicfunctionadd(){$message="Notification: New report submitted!";//Call a method from SmsOutgoingsController with parameter$this->requestAction('/sms_outgoings/notify_user',array($user_id,$message))
