Yii2-How to access a variable from model to a controller? - variables

Question

I am working on yii2. I have came across a point in which I have to send an email to a person when a meter is installed and it's images are uploaded to the server. Fro this I have already configured the swift mailer.
There is a model named Installations which have a function which saves all the installation data.
public static function saveAll($inputs){
$coutner = 0;
$arr_status = [];
foreach ($inputs as $input) {
$s = new Installations;
foreach ((array)$input as $key => $value) {
if($key != 'image_names') {
if ($s->hasAttribute($key)) {
$s->$key = $value;
}
}
}
$user = Yii::$app->user;
if (isset($input->auth_key) && Users::find()->where(['auth_key' => $input->auth_key])->exists()) {
$user = Users::find()->where(['auth_key' => $input->auth_key])->one();
}
$s->created_by = $user->id;
if (Installations::find()->where(['ref_no' => $input->ref_no])->exists()) {
$arr_status[] = ['install_id' => $input->install_id, 'status' => 2, 'messages' => "Ref # Already exists"];
continue;
}
$s->sync_date = date('Y-m-d H:i:s  ');
if($s->save()){
if ($s->istallation_status == 'Installed') {
Meters::change_status_byinstall($s->meter_msn, Meters::$status_titles[4]);
}
else if ($s->istallation_status != 'Installed' && $s->comm_status =='Failed')
{
Meters::change_status_byinstall($s->meter_msn, Meters::$status_titles[5]);
}
$arr_status[] = ['install_id' => $input->install_id, 'status' => 1];
$coutner++;
if (isset($input->doc_images_name)) {
foreach ($input->doc_images_name as $img) {
$image = new InstallationImages;
$image->image_name = $img->image_name;
$image->installation_id = $s->id;
$image->save();
}
}
if (isset($input->site_images_name)) {
foreach ($input->site_images_name as $img2) {
$image2 = new InstallationImagesSite;
$image2->image_name = $img2->image_name;
$image2->installation_id = $s->id;
$image2->save();
}
}
}else{
$arr_status[] = ['install_id' => $input->install_id, 'status' => 0, 'messages' => $s->errors];
}
$status = $s->istallation_status;
$msn = $s->meter_msn;
$com = $s->comm_status;
// want to pass these variables to the controller function
}
return ['status' => 'OK', 'details' => $arr_status, 'records_saved' => $coutner];
}
Now There Is a Controller name InstallationController. This controller contains all the APIs for my mobile application. Below are two main functions in it
public function actionAddnew()
{
$fp = fopen('debugeeeeeee.txt', 'w+');
fwrite($fp, file_get_contents('php://input'));
fclose($fp);
$inputs = json_decode(file_get_contents('php://input'));
return Installations::saveAll($inputs);
}
public function actionSavephoto()
{
try {
$count = 0;
foreach ($_FILES as $f) {
$dd = pathinfo($f['name']);
if (!isset($dd['extension']) || !in_array($dd['extension'], array('jpg', 'png', 'gif'))) {
return ['status' => 'ERROR', 'uploaded_files' => $count, 'message' => 'Invalid File'];
break;
}
if (move_uploaded_file($f['tmp_name'], Installations::UPLOAD_FOLDER . $f['name'])) {
$count++;
return ['status' => 'OK', 'uploaded_files' => $count];
break;
} else {
return ['status' => 'ERROR', 'uploaded_files' => $count];
break;
}
}
} catch (Exception $x) {
return ['status' => 'ERROR', 'message' => $x->getMessage()];
}
}
The mobile application will call the Addnew() api and after that it will call the savephoto. Now I want to pass $msn,$status and $com values from the Model to the controller function Savephoto.
For this I have tried to use session variables but still I am unable to get by desired result(s).
I have also checked the question Yii, how to pass variables to model from controller?
but it didn't worked for me.
How can I achieve it?
Any help would be highly appreciated.

The only way to get those values out of saveAll() is to return them. Presently, they are defined on an object in $s that is overwritten each loop. The best way to do that seems to be creating an array outside of your foreach ($inputs... loop and appending each created Installations object.
Return that at the end, and pass it (or just the relevant element from it) into actionSavephoto() as a parameter. Then, those values will be accessible of properties of that passed object. This handling will occur in the code that is not pictured which calls actionAddNew() and then actionSavephoto()
