You have got to have some kind of server backend for synchronization of the local database. You can't do that using just the static HTML pages.

Your application and server have to have a way to talk to each other using a web service protocol, like SOAP or JSON/REST. Then your application has to translate the data from the database into such web service data objects.

Both your local database and the server (in case of more than one client) will have keep the records of at least the times of last synchronizations so both know what should be sent over the air in order to become in sync.

Also, in the usual case of more than one client, you have to solve the problem of conflicts resolution.

Web service versioning is important as well, as there will be very likely a need to improve the communication channel, maybe there will be changes in the database model to be synchronized.

As you can see, the idea of synchronizing local database to a server is not that simple, and if you think you can do it in a simple way, in time you'll realise that you're gradually reimplementing the aforementioned ideas.

Do a research on web service technologies, writing web services-aware apps, on synchronization with web services and on Reachability, for starters.

To check internet availability, check out the Reachability class from Apple. See this article.

To send data to a simple HTTP form via POST use NSURLConnection like in this article.
