Phalcon framework, can't get data from modal to controller - php

Question

public function searchStudent($student)
{
$db = Di::getDefault()->get('db');
$sql = 'SELECT * FROM students WHERE insurance_number = "'.$student['searchInsurenceNum'].'"';
$sth = $db->prepare($sql);
$sth->execute();
When i check here die(var_dump($sth->fetchAll())), i am getting array with data from database.
return $sth->fetchAll();
}
public function searchAction()
{
$request = new Request();
$response = new Response();
if ($request->isPost()) {
(new ContactsStorage())->searchStudent($request->getPost());
}
But in controller when i call fuction die(var_dump((new ContactsStorage())->searchStudent())), i am getting empty array .
$this->view->setVar('findData', (new ContactsStorage())->searchStudent());
}

Answer 1

Maybe your request is not a POST ? ($request->isPost())
by using this method you're allow to find your students only on POST request. Remove condition and try again.
If you have model Student which extends \Phalcon\Mvc\Model you can use magic static methods findBy{$FeildCamelCasedName} so there is no need to create extra repositories and even methods if you want to ge tsome entity by simple criteria:
$findData = Student::findByInsuranceNumber($in);
also you can find one element by such criteria by simply using magic method findFirstBy{$Field}
