In my database table, i have a field for price and quantity. Is there a way I could use a select to get 2 values from the database? What I mean is I will create a select field where when I select wholesale it will bring out the price and quantity and if I select retail, it will bring the price and the quantity.

I have a form which allows the user to select ASC center and add students data for each time. The scenario is a user selects ASC center from the drop down list. Upon selecting the ASC center, a function called StudentList returns the students for the selected ASC center. Now these students should be populated for each row. I have assigned a class for the Student input field and used each function of the jquery to populate all the students field with the data returned by the StudentList function. But the problem is the data gets populated for the very first row correctly. But as soon as the user clicks on Add Student to add more student for a particular time or clicks on Add Time to add new time then the previously populated data gets cleared. The expected is that the once the ASC center is selected from the drop down by the user, then no matter how many new students or new time is added by the user on the form by clicking Add Student or Add Time button then the previously populated data should not be cleared. The below image shows the students populated for the first student row on selecting the ASC center https://pasteboard.co/PDm9UwYMK4CI.png Below is the image which shows the Students input field gets cleared when a user adds new student or adds new time https://pasteboard.co/fzUipa4ZYtCO.png Below is the function StudentList which returns the list of students for specific ASC center. public function actionStudentLists($id) { $countstudents = Student::find()->where(['ASCId' => $id])->count();//Counts number of students $Students = Student::find()->where(['ASCId' => $id])->all(); // Execute students for ASCId if ($countstudents > 0) { echo "<option value>Select Students</option>"; foreach ($Students as $Student) { ob_start(); echo "<option value='" . $Student->StudentId . "'>" . $Student->StudentName . "</option>"; } } else { echo "<option> - </option>"; } } Below is the form <?php use yii\helpers\Html; use yii\bootstrap\ActiveForm; use yii\jui\DatePicker; use wbraganca\dynamicform\DynamicFormWidget; use app\models\Ascassignment; use app\models\Asccenter; use kartik\time\TimePicker; use yii\helpers\ArrayHelper; use app\models\Student; ?> <script> // When user clicks on Add Student button $(function () { $(".dynamicform_student").on("beforeInsert", function(e, item) { $.post("index.php?r=student/student-lists&id=' .
