| how to dynamically add a page to a site |
|
|
Hello all,
I am developping a news module which must have the ability to post a news item on multiple sites. Upon creating the news item, the user decides which site the item is to appear on.
What I have so far, the module :
- stores all data in the database,
- successfully 'views' or displays the news item iff the user chose to have the news item appear on that particular site.
In the view page, the module shows a Title and short description for the news article. A "Read more..." link must bring the user to the actual article's page related to this item.
My problem
I need to find a way to dynamically create the page on which the main article is to appear. This page must be created on all sites on which the user wants it to appear when the the news item was created. Needless to say that it would be unacceptable to have the user create the page for the article in question on all, say four sites, on which the item will appear.
My question is as follows:
How can I dynamically "add a page" to a site, or multiple sites, which would also include dynamically creating its title and content, from the module's edit page.
I appreciate anyone's help, and I am more than willing to elaborate on my problem, or clarify on its issues.
Thanks in advance!

OK, I thought I'd follow up with my improvements on the matter in case anyone will EVER want to attempt what I'm trying to do.
After realizing that DNN's data provider model refers to 'pages' as 'Tabs', i can see that the Tabs table in the portal's database is updated with all the settings the page was given upon its creation. Each tab, or page, is given a unique id called TadId, along with 20 other properties such as TabName, IsVisible, Title, Description, Keywords etc... Therefore, in order to add a page to the site, I will simply add another item to this table.
Great. Now, I THINK that I have 'created' a page, but in order to give this page a purpose, I need to do two more things: first, dynamically insert an HTML/text module which will contain the title and Article, secondly create a link to it.
Returning to the app's database and looking at the ModuleDefinitions table, we see that DNN refers to each installed module with this table's primary key, ModuleDefID. The HTML/TEXT's ModuleDefId is 109.
At this point, the application needs to keep track of the different instances of these modules which appear on different pages, huhm, tabs. This is where the TabModules table comes in: We see that it links ModuleId and TabId, the two primary keys from the Modules and Tabs table, respectively.
Therefore, to add a page to the DNN site, one must add to the Tabs, Modules, and TabModules tables.
I still haven't figured out how to create a link such that DNN will automatically look at these tables and generate the page. Also, I noticed that the Modules table only contains records of the module's Title and not the content of the HTML/Text portion. Where is the content of this module saved?

Am I completely off with my technique of adding a page dynamically? Can anyone offer me input/feedback so that I feel as though I'm actually going to accomplish this feat?
Please, if anyone knows of an easier way to add a page using code, I'm all ears.

Have you looked at the DotNetNuke.Entities.Tabs.TabController.AddTab metnod? This mthod allows you to create page.
