I'm trying to publish newsletters online (I create all the newsletters using Newsletter module)

1. I added additional field called "Publish_Online" to the NewsletterType.php and Newsletter.php

2. I created new page types called NewsletterHolder and NewsletterPage.

3. In the NewsletterHolder I included a function:

public function NewsletterTypes() {
return DataObject::get("NewsletterType","");
}

to get all the data from the table NewsletterType from db.

In the NewsletterHolder template I have this code:

<% if NewsletterTypes %>
<% control NewsletterTypes %>
<% if Publish_Online="true" %>
<% if DraftNewsletters %>
<% control DraftNewsletters %>
<% if Publish_Online="true" %>
<p>$Title<br>Date: $Created<br><a href="$baseURL/newsletter/?id={$ID}">Read</a></p>
<% end_if %>
<% end_control %>
<% end_if %>

<% if SentNewsletters %>
<% control SentNewsletters %>
<% if Publish_Online="true" %>
<p>$Title<br>Date: $Created<br><a href="$baseURL/newsletter/?id={$ID}">Read</a></p>
<% end_if %>
<% end_control %>
<% end_if %>
<% end_if %>
<% end_control %>
<% end_if %>

4. Now when I click on the link <a href="$baseURL/newsletter/?id={$ID}">Read</a> a go to the page (with type "NewsletterPage").
And I need to read this parameter id={$ID}? How to do that?
Or there are other ways to pass parameters between pages?

This what I found in newsletter module to preview newsletters.

Parameter is being passed in this way:
$previewLink = Director::absoluteBaseURL() . 'admin/newsletter/preview/' . $this->ID;

And here is how $this->ID is processed:

/**
* Preview a {@link Newsletter} draft.
*
* @param HTTPRequest $request Request parameters
*/
public function preview($request) {
$newsletterID = (int) $request->param('ID');
$obj = DataObject::get_by_id('Newsletter', $newsletterID);
$templateName = ($obj && ($obj->Parent()->Template)) ? $obj->Parent()->Template : 'GenericEmail';

// Block stylesheets and JS that are not required (email templates should have inline CSS/JS)
Requirements::clear();

// Set template specific variables before passing it to the template
$obj->Body = $obj->Content;

return $this->customise($obj)->renderWith($templateName);
}

How is that all connected?

I know that I'm talking to myself here. :)
But I discovered, that to pass parameters between page1 and page2 you need to define a function in the page1 controller,
for example like in the newsletter module:

public function preview($request) {
$newsletterID = (int) $request->param('ID');
$obj = DataObject::get_by_id('Newsletter', $newsletterID);
return $this->customise($obj)->renderWith("page2");
}

and than the link like "http://www.mysite.com/page1/preview/12" inside "http://www.mysite.com/page1/"
would go through that function "preview", and the parameter $request would be "12".
Using renderWith("page2") in the function "preview" you can define a new page based on "themes/mytheme/Layout/page2.ss".

-----------------------------------------------

Please advise where to read about this process more? And did I understand everything correctly?

thanks
