XHTML MP Tutorial: Processing Form Data at the Server-side of WAP Applications

21.4. At the Server-side

At the server-side, the name specified by the name attribute of <input> and <select> elements can be used to retrieve the data. You can make use of your favorite server-side technology to do the processing required by your WAP application. Common server-side technologies include ASP, Java Servlet, JSP, Perl, and PHP.

In the earlier XHTML MP example, the form data is sent to the processing.asp file, where some ASP (Active Server Page) code will do the processing. Below is the ASP code in the processing.asp file. It just prints out the form data received at the server. In real WAP applications, the server probably needs to do more complicated processing. For example, storing the form data to a database such as MySQL, PostgreSQL, Microsoft SQL Server, Oracle Database, etc.
