Multiple events after update in yii2 - yii2

Question

I want to notify users through sms whenever a row gets updated. I've added the following code -
$transaction->commit();
$mobiletemp = User::find()->leftJoin('auth_assignment', 'auth_assignment.user_id = user.id')->select('mobileno')->andWhere(['auth_assignment.item_name' => 'c_apo'])->column();
$mobile = implode(",", $mobiletemp);
return $this->redirect('http://api.msg91.com/api/sendhttp.php?' . http_build_query(['sender'=>'TSTMSG', 'route'=>'4', 'mobiles'=> $mobile, 'authkey'=>'My Auth Key', 'country'=>'0','message'=>('Dear Sir, WP '. $wpno. ' is waiting for your approval. Please take necessary steps. Thank You.')]));
return $this->redirect(['view', 'id' => $model->wp_no]);
With this code user is getting sms notification. But, the there's a return code from the service provider which is being displayed as output. And the last piece of code to redirect to the view page is not getting read. I have to add multiple block of this notification code after update. Please let me know what is the best possible to way to handle this situation. I want to display the view after update also, users should get the notifications.
My present code after using curl
if ($flag) {
$transaction->commit();
$mobiletemp = User::find()->leftJoin('auth_assignment', 'auth_assignment.user_id = user.id')->select('mobileno')->andWhere(['auth_assignment.item_name' => 'c_apo'])->column();
$mobile = implode(",", $mobiletemp);
$curl = new curl\Curl();
$response = $curl->setGetParams(['sender'=>'TSTMSG', 'route'=>'4', 'mobiles'=> $mobile, 'authkey'=>'My Auth Code', 'country'=>'0','message'=>('Dear Sir, WP '. $wpno. ' is waiting for your approval. Please take necessary steps. Thank You.')])->get('http://api.msg91.com/api/sendhttp.php');
if ($curl->errorCode === null) {
return $this->redirect(['view', 'id' => $model->wp_no]);
}else {
// List of curl error codes here https://curl.haxx.se/libcurl/c/libcurl-errors.html
switch ($curl->errorCode) {
case 6:
//host unknown example
break;
}
}
}

Answer 1

You can use curl to send the request to the API and then use
return $this->redirect(['view', 'id' => $model->wp_no]);
For the Curl calls you can use linslin library for Yii2 which is very easy to use.
Just make sure you have cURL installed or take the following steps to
install cURL.
First Install CURL by typing $ sudo apt-get install curl
Then Restart Apache by typing $ sudo service apache2 restart
Then Install PHP5 CURL by typing $ sudo apt-get install php5-curl
Will prompt to install... type y or yes!
Then Restart Apache by typing $ sudo service apache2 restart Done!
A simple curl get request using linslin/Curl will look like this.
// GET request with GET params
// http://example.com/?key=value&scondKey=secondValue
$curl = new curl\Curl();
$response = $curl->setGetParams([
'key' => 'value',
'secondKey' => 'secondValue'
])
->get('http://example.com/');
So your code will look like this
$transaction->commit();
$mobiletemp = User::find()->leftJoin('auth_assignment', 'auth_assignment.user_id = user.id')->select('mobileno')->andWhere(['auth_assignment.item_name' => 'c_apo'])->column();
$mobile = implode(",", $mobiletemp);
$curl = new curl\Curl();
$response = $curl->setGetParams(['sender'=>'TSTMSG', 'route'=>'4', 'mobiles'=> $mobile, 'authkey'=>'My Auth Key', 'country'=>'0','message'=>('Dear Sir, WP '. $wpno. ' is waiting for your approval. Please take necessary steps. Thank You.')])
->get('http://api.msg91.com/api/sendhttp.php');
if ($curl->errorCode === null) {
return $this->redirect(['view', 'id' => $model->wp_no]);
} else {
// List of curl error codes here https://curl.haxx.se/libcurl/c/libcurl-errors.html
switch ($curl->errorCode) {
case 6:
//host unknown example
break;
}
}
