asynchronously submit values to controller? yii2 - php

Question

So here's the deal. The ActiveForm below is supposed to receive two variables: $tt (radio) and $value (string numeric input) and send them to controller.
$value needs to be validated based on different rules and scenarios, which are defined in InputField model. $tt is radio value, so I'm not defining rules for it as of now.
The trick is, I'd like there to be some sort of input validation for $value, and the rules for it should change depending on what the user set as his $tt value. With this kind of configuration, controller never receives neither $tt, nor $value, I think the reason is conflicting rules for it.
Ideally, I would like my view to send checked radio $tt value (with jQuery or smthng) to controller, and for controller then to set scenario for the model so it has proper validation rules set up, which input field for $value in the view will operate on.
Yii2 experts: 1) can you explain me why my controller fails to receive any value. 2)suggest anything for what I was planning to do?
`
//View fragment
$valueForm = ActiveForm::begin([
'id' => 'input-field',
'action' => ['value-search/index'],
'method' => 'post',
'options' => ['class' => 'form-horizontal'] ]); ?>
<?= $valueForm->field($valueModel, 'tt')
->radioList(['P_sat'=>'Sat. Pressure', 'T_sat'=>'Sat. Temperature'])
->label('Select table type'); ?>
<?= $valueForm->field($valueModel, 'value')
->textInput(['options' => ['type'=>'number', 'name'=>'value','id'=>'value']]); ?>
<?php ActiveForm::end() ?>
//Model
class InputField extends \yii\base\Model
{
const SCENARIO_PSAT = 'P_sat';
const SCENARIO_TSAT = 'T_sat';
public $tt;
public $value;
public function scenarios() {
return [
self::SCENARIO_PSAT => ['tt','value'],
self::SCENARIO_TSAT => ['tt','value'],
];
}
public function rules() {
return [
['tt','safe'],
['value', 'double', 'numberPattern' => '/[0-9]+?(\.[0-9]{0,5})?/', 'min' => 0, 'max' => 22064,
'on' => self::SCENARIO_PSAT],
['value', 'double', 'numberPattern' => '/[0-9]+?(\.[0-9]{0,5})?/', 'min' => 0, 'max' => 373.95,
'on' => self::SCENARIO_TSAT],
];
}
//Operating action from the controller
public function actionIndex()
{
$inputModel = new InputField;
$inputModel->load(\Yii::$app->request->post());
$tt = $inputModel->tt;
switch($tt) {
case 'P_sat': $inputModel->scenario = $inputModel::SCENARIO_PSAT;
break;
case 'T_sat': $inputModel->scenario = $inputModel::SCENARIO_TSAT;
break;
default: throw new UserException('setTableType is not returning shit');
}
if ($inputModel->validate('value')) {
$searchValue = $inputModel->value;
$this->test = $inputModel->tt;
$this->test2 = $inputModel->value;
} else {
throw new UserException('Input is not validated');
}
return $this->render('index', [
//'provider' => $provider,
'array' => $this->test,
'array2' => $this->test2
]);
}
`
Both test and test2, which are supposed to receive $tt and $value from the model, are NULL :(

Scenario has to be set before loading a value
public function actionIndex()
{
$inputModel = new InputField;
$inputModel->load(\Yii::$app->request->post());
$tt = $inputModel->tt;
switch($tt) {
case 'P_sat': $inputModel->scenario = $inputModel::SCENARIO_PSAT;
break;
case 'T_sat': $inputModel->scenario = $inputModel::SCENARIO_TSAT;
break;
default: throw new UserException('setTableType is not returning shit');
}
if ($inputModel->load(\Yii::$app->request->post()) && $inputModel->validate('value')) {
$searchValue = $inputModel->value;
$this->test = $inputModel->tt;
$this->test2 = $inputModel->value;
} else {
throw new UserException('Input is not validated');
}
return $this->render('index', [
//'provider' => $provider,
'array' => $this->test,
'array2' => $this->test2
]);
}
