Show first subpage?
27 August 2009 at 4:14am
Simple requirement here...I have a News page which contains a number of NewsItem subpages. At the moment, when I go to the News page, I see a submenu displaying all the NewsItem titles. What I would like is to have the first one of these auto-selected and displayed on the page, as if the user has clicked the first item in the submenu. How would I do this?

You could add a redirection to the index (default) method of news page:
function index() {
// untested
Director::redirect($this->Children()->First()->URLSegment);
}Preferably though, you could push the response of that page instead (and avoid the redirect). Something like:
function index() {
// untested
$page = $this->Children()->First();
return $this
->customise('Title' => $page->Title, 'Content' => $page->Content)
->renderWith(array());

Hmm, not quite there. The second method qives me the following error:
Parse error: syntax error, unexpected T_DOUBLE_ARROW in /var/www/fsbi/mysite/code/SubpageHolder.php on line 15
SubpageHolder is the subclass of Page I used for this purpose.
The first method looks as if it should work but for the fact that it redirects to a subpage with the wrong URL, but this brings up another issue. Let's say my page is /news/ and I want it automatically directed to the first news article. Your first method is sending me to
/news/article1
Fair enough, that's probably how it should be, but the actual URL is /article1 (i.e., without the prefacing /news). Why this should be the case, I don't know, because article1 has been created in the CMS as a subpage of the news page. I would have thought the URL would be indicative of this, but it isn't. Is there a way to make it so?

The answer is obvious to me now:
function index() {
// untested
$url=Director::baseURL().$this->Children()->First()->URLSegment;
Director::redirect($url);
}Having done a bit of research I see that the question of nested URLs has been going on a long time now. Looking forward to 2.4!

Hi,
I don't know if it's good writen, but.
I want: if first menuitem Content is empty get Content of next menuitem (if exist), so solving for me was that code (overriding iindex() method in Page_Controller)
function index() {
if ( $this->ClassName == 'Page' &&
( empty( $this->Content ) || strlen( $this->Content ) < 6 ) && ( $children = $this->Children() )
) {
$url = Director::baseURL() . $this->Children()->First()->URLSegment;
Director::redirect($url);
}
else {
return $this->renderWith( array( $this->ClassName, 'Page' ) );
}
}I hope that it helps to others.......
