| Here we will see a nice, simple example of how a user can book a movie tickets through his mobile phone. We are going to use ASP and Access database to retrieve and store information. No Registration is required. Take a look on Database structure first. (Tickets.mdb) We have 4 Tables,
[Movie : Stores Movie names and stars in movie, Unique movieId(Auto Number Field).]
[Theater : Stores Theater names each one uniquely identified by theaterid (Auto Number Field).]
[Shows : Theaters running particular movies and its timings, seats availability and per ticket price, MovieId and TheaterId as Foreign Keys. Each show identified as Showid (Auto Number Field)].
[Booking : Unique booking id generated for each booking done. you also store name, phone number and number of seats booked of the users.
Here is the Relational Structure and Sample Data Used for Demo
Before writing code understand basic
For demo you can put all this .wml and .asp files in to one directory and map it as a virtual directory is IIS. Since it uses DSN-less connection put database also in the same directory.
When you call or redirect to .asp file your asp file should generate WML code instead of HTML, because that is what your w@p enable device or simulator would understand. This can be done by first throwing W@P’s mime-types from an ASP program. The following lines should be included in your ASP program as it is. <%Response.ContentType="text/vnd.wap.wml"%>
<%Response.write("<?xml version=""1.0""?><!DOCTYPE wml PUBLIC ""-//WAPFORUM//DTD WML 1.1//EN"" ""http://www.wapforum.org/DTD/wml_1.1.xml"">")%> |
After this you can throw any WML content. First line is important as browser sould know what type of data is going to come. Passing parameters to ASP program
At time you accept input from the user which needs to be pass to an ASPprogram. Here are WML statements to pass parameters in a name valuepair to your ASP program.Using your <go> tag you call your nextWML DECK or an ASP program. Right !. <do type="accept" label="Select Movie">
<go href="theaters.asp" method="get" >
<postfield name="mid" value="$(mid)" />
</go>
</do> |
Here you can also specify method ( ie. GET/POST although POST is notsupported by few devices we will use GET Method ) and the parametersyou want to pass by using <postfield> tag. <postfield> tagrequires name and value attributes.
That's enough to proceed
Here is the entire code with explanation This is the initial screen which stays for few seconds and then redirects you to movie.asp munamobile.wml <wml>
<card ontimer="movie.asp">
<timer value="30"/>
