ajax - In a user's Edit Info form, how do I include the name of the field(s) and user's input value(s) in a response from the model -

on yii2 project, in user's edit info form (inside modal):

i'm figuring out fields changed using jquery .change() method, , i'm grabbing value jquery's .val() method.

however, want less javascript , more yii's framework.

i can see in yii debugger (after clicking ajax post request) yii smart enough know fields changed -- it's showing sql queries update fields changed.

what need change in controller of action have yii include name of field changed -- including it's value -- in ajax response? (since goal update main view new values)

public function actionupdatestudentinfo($id) {     $model = \app\models\studentsupportstudentinfo::findone($id);         if ($model === null) {         throw new notfoundhttpexception('the requested page not exist.');     }      $model->scenario = true ? "update-email" : "update-studentid";     if ($model->load(yii::$app->request->post()) && $model->save()) {          return $this->renderajax('_student_support_alert_success');     }     return $this->renderajax("_edit_student_info",[         "model" => $model,     ]); } 

i'm returning static success view.

you can use $model->dirtyattributes after load data $attrib => $value pair array.

http://www.yiiframework.com/doc-2.0/yii-db-baseactiverecord.html#getdirtyattributes()-detail (this docs says:)

returns attribute values have been modified since loaded or saved recently.

the comparison of new , old values made identical values using ===.

public array getdirtyattributes ( $names = null )
