delphi webbroker: passing multiple parameters and using!

Hi there,

Hopefully this is one of those questions you say "cool easy points".

I'm using Delphi webbroker for the first time creating dynamic web pages. I've got a cgi program running on the server verifying login and p/w info from "loginpage.htm" (the FORM ACTION on "checker.exe" runs this and is the default action of this .exe). A successful login brings up a page with a listbox with some values in it. I want to use those values selected. I.e the user chooses "apple" in the listbox, clicks "buy apple" and that runs another action of the same executable. It would be easy if i could have two submit buttons (i've used one for logging in of course).

I've used request.contentfields to get the first set of values (eg login and p/w) but when i use it to get the listbox values i can't get anything. How do i do it? Do i need to create a seperate .exe? Can i specify if the request was from page "blah" do this...?

Your solution is to use Multiple actions, for example you can have two WebActions:
in waLogin you can set path as /login, and /buy in waBuy action.
in Login form make the action = "checker.exe/login" and in the form that contains the list box you can set the action in HTML: action="checker.exe/buy", then you can have only one CGI application serves unlimited number of actions.

I'll post here this topic from my EBook Delphi Programming Guide (Web development chapter)


In real web server programming you need to write multiple actions for different requests. For instance if you need to write a telephone directory which contains search and subscription forms you didn't need to write two web applications: one for search and one for subscription such as:



Instead you can write only one web application and create two web item actions, the first one can be called waSearch and the other waSub. waSearch contains /search in it's PathInfo property and waSub contains /sub in it's PathInfo. PathInfo property makes your web server respond to your request according to passed path, for example if you pass below URL to your application:


The first action will be executed (waSearch), and if you pass below URL:


The second action will be executed to respond to your request.

You can combine PathInfo with parameters such as:


Returned value of Query property of Request will be: "name=Motaz"

By this method you can write only one web server application to respond to multiple HMTL forms and queries.

There is a complete code of Telephone directory application with this article. Copy this sample to a directory and make a WWW Alias for it. Make sure that read and execute permission is checked for that Alias.

There is a third action in this example called waAll which returns all records. To call this action write:
