Yii2: how to pretend in mail

I can send mail using the swiftmailer extension. I can also include a view file from the @ app / mail folder.

Now I am wondering how I can include data for my models, for example, for example I have Model City.php and an associated view as view.php or index.php (grid-view), how can I include data, received in view.php (single entry) or table data in index.php in the body of the email.

In short, I want to include the default data presented in yii2 in views or index in the body of the email.

Hi I have seen this example as - Yii::$app->mailer->compose('viewName', ['variable' => $variable])

another example - Yii::$app->mailer->compose('contact/html', ['contactForm' => $form])

I've tried this without much success:

Yii::$app->mailer->compose('medicine-request-entry/html',['medicine_request_entry'=>$form])

      

        
        
        
      

    

but I am getting the variable variable undefined. medicie_request_entry

is a folder in the views folder. (not in @ app / views)

but couldn't get it. Let's say the name of my view in / mail / subfolder says report.php and I have a folder in my signatures views / city / and the city folder has view.php and index.php, how can I specify this in a parameter in the example code ...

Any suggestion would be greatly appreciated.

Thank.
