Send sms to delete user from database Kannel

Question

I need to send an sms to my application and based on the text, do an action. Now I want to delete a user when he/she sends an sms with the keyword UNSUBSCRIBE. I want to capture the number of the sender and the text to my phpfile which will do the delete action.

here is my sms-service configuration

group = sms-service
keyword = 
catch-all = true
post-url = "http://localhost/Maisha/Functions/receivesms.php?phone=%p&text=%S"

How do I get my values to my php file (receivesms.php) then delete the appropriate user based on their number? All help will be appreciated.

Answer 1

First you should not delete the user from your database, you might flag them as unsubscribed as they could have more than one subscription if you follow the Short/Long Code subscription model. Also send the keyword 'UNSUBSCRIBE' should be 'STOP' or 'STOP ALL' (if more than one subscription). Note the keyword 'STOP' is a carrier mandate for all subscription.

As for parsing out the incoming sms, what method are you using to send with Kannel? GSM Modem? If this is a business application I would suggest going with a SMS Aggregator like OpenMarket or Twilio.
