Insert in yii2 from different controller - sql

Question

I am tring to insert data in a table.
trying like this but it`s not working.
$sql = $queryBuilder->insert(' HRMS_candidateEducation', [
'HRMS_candidateEducationCandidateID' => $candidateID,
'HRMS_candidateEducationDegree' => $data['Degree'.$i],
'HRMS_candidateEducationUniversity' => $data['University'.$i],
'HRMS_candidateEducationCollege' => $data['College'.$i],
'HRMS_candidateEducationYear' => $data['Specilization'.$i],
'HRMS_candidateEducationSpecilization' => $data['Specilization'.$i],
], $params);
What is incorrect?
using
use yii\db\QueryBuilder;
use app\models\CandidateEducation;

Answer 1

This function seem only create the SQL statement see doc
insert() Creates an INSERT command
for executing the command i think you shoul try this way
Yii::$app->db->createCommand()->
insert(' HRMS_candidateEducation', [
'HRMS_candidateEducationCandidateID' => $candidateID,
'HRMS_candidateEducationDegree' => $data['Degree'.$i],
'HRMS_candidateEducationUniversity' => $data['University'.$i],
'HRMS_candidateEducationCollege' => $data['College'.$i],
'HRMS_candidateEducationYear' => $data['Specilization'.$i],
'HRMS_candidateEducationSpecilization' => $data['Specilization'.$i],
], $params)->
execute();

Answer 2

I found another solution to my question.
This is what i did. by following this link.
public function actionCreate()
{
$a=new A;
$b=new B;
if(isset($_POST['A'], $_POST['B']))
{
// populate input data to $a and $b
$a->attributes=$_POST['A'];
$b->attributes=$_POST['B'];
// validate BOTH $a and $b
$valid=$a->validate();
$valid=$b->validate() && $valid;
if($valid)
{
// use false parameter to disable validation
$a->save(false);
$b->save(false);
// ...redirect to another page
}
}
$this->render('create', array(
'a'=>$a,
'b'=>$b,
));
}
