I have a code written in Yii-php which will works in following way…
When user click on upgrade package option. A curl request will run and perform task on remote server (REST API CALL).
After success the payment will be done also on a remote server (Using Recurly API)
After payment success the records will be saved to database.
Now, My logic fails when user close the browser during this process.
I want to restrict the user or remind the user that "Your transaction is in process. Please wait".
Please suggest me a solution…
