binding values submitted from a View to a Controller - php

Question

I am coding a form to get user input and then pass that information to a controller and execute a function based on that, at this point I can not pass the data to the controller using POST method, I get empty vars.
So the Controller function display the view form correctly, I can type on the textboxes, after press submit button I get a setFlash custom message that the parameters are empty. I am using a model class with just two parameters.
a) This is the model:
<?php
namespace app\models;
use Yii;
use yii\base\Model;
class SendmailForm extends Model
{
public $template;
public $emtransport;
/**
* #return array the validation rules.
*/
public function rules()
{
return [
[['template', 'emtransport'], 'required'],
];
}
}
b) This is the view:
<?php
use yii\helpers\Html;
use yii\bootstrap\ActiveForm;
use yii\captcha\Captcha;
$this->title = 'Send Mail';
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="site-contact">
<h1><?= Html::encode($this->title) ?></h1>
<?php if (Yii::$app->session->hasFlash('sminfo')): ?>
<div class="alert alert-success">
<?= Yii::$app->session->getFlash('sminfo');?>
</div>
<?php else: ?>
<p>
SendMail Exercise. Please choose needed options bellow:
</p>
<div class="row">
<div class="col-lg-5">
<?php $form = ActiveForm::begin(['id' => 'sendmail-form']); ?>
<?= $form->field($model, 'template')->textInput(['autofocus' => true]) ?>
<?= $form->field($model, 'emtransport') ?>
<div class="form-group">
<?= Html::submitButton('Submit', ['class' => 'btn btn-primary', 'value'=>'one', 'name'=>'sendbtn']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
</div>
<?php endif; ?>
</div>
And this is the controller's function:
public function actionSendmail(){
$model = new SendmailForm();
if ($model->load(Yii::$app->request->post())) {
$template = Yii::$app->request->post('template');
$emailTransport = Yii::$app->request->post("emtransport");
if($emailTransport=="local"){
for($i=0;$i<=2;$i++){
$xclient = 'client' . $i;
\app\models\User::findByUsername($xclient)->sendMail($template, 'Welcome To XYZ Services', ['accountInfo' => 'www.mysite.com']);
}//end of for loop
Yii::$app->session->setFlash("sminfo", "Emails sent successfully to the Clients");
return $this->refresh();
}//end of second if loop
else{
Yii::$app->session->setFlash("sminfo", "Params could not be verified!. Contact Tech Support");
return $this->refresh();
}
}//end of post if loop
return $this->render('sendmail', [
'model' => $model,
]);
}
The idea is to get the values from the view, at this moment I am getting empty values-

Answer 1

Two parts below:
$template = Yii::$app->request->post('template');
$emailTransport = Yii::$app->request->post("emtransport");
Change the following:
$template = $model->template;
$emailTransport = $model->emtransport;
After editing
public function actionSendmail(){
$model = new SendmailForm();
if ($model->load(Yii::$app->request->post())) {
$template = $model->template;
$emailTransport = $model->emtransport;
if($emailTransport=="local"){
for($i=0;$i<=2;$i++){
$xclient = 'client' . $i;
\app\models\User::findByUsername($xclient)->sendMail($template, 'Welcome To XYZ Services', ['accountInfo' => 'www.mysite.com']);
}//end of for loop
Yii::$app->session->setFlash("sminfo", "Emails sent successfully to the Clients");
return $this->refresh();
}//end of second if loop
else{
Yii::$app->session->setFlash("sminfo", "Params could not be verified!. Contact Tech Support");
return $this->refresh();
}
}//end of post if loop
return $this->render('sendmail', [
'model' => $model,
]);
}

Answer 2

I did some changes to the Controller and now it works, those are them:
//at the beginning of the Controller:
use app\models\SendmailForm;
//two lines changed in the function:
$model->template = $_POST['SendmailForm']['template'];
$model->emtransport = $_POST['SendmailForm']['emtransport'];
That's all I needed. Best regards
