EiffelWeb Basic Sample

This sample shows how to retrieve and display information from a basic form on a web page.

Note: This sample requires a web server supporting CGI in order to be run. Both the Internet Information Services web server from Microsoft and the GNU Apache server may be used.

Compiling

To compile the example:

  • Launch EiffelStudio.
  • Click Add project
  • Browse to $ISE_EIFFEL\examples\web\basic\.
  • Choose web.ecf
  • Choose the location where the project will be compiled, by default the same directory containing the configuration file.
  • Click OK.

Installing

You should copy the file web_demo.exe in the cgi_bin directory of your web server and the file sample.html in a directory on the web server.

Running

To run the example, access the page sample.html that you copied on the web server with a web browser (typically ''http://localhost/sample.html''). Fill in the text field with a username and click Submit. You should see a page displaying the name you just entered. Although not earth-shattering, this sample shows the basis for building more complex forms processing in Eiffel.

Under the Hood

This basic sample has just one class SAMPLE which inherits from CGI_INTERFACE. SAMPLE implements execute which retrieves the name entered in the form and creates a new HTML page with it.

See the EiffelWeb class reference for the class interfaces.
