Finding Templates

[Joss]

Here is an interesting one.

I know how to find pages based on templates, but can I find templates based on pages? Or perhaps a field in a page?

The reason is that I want to list posts by template.

Now, I could manually create a select field with a manual list of particular templates and use that to search, but that would mean manually updating that every time I (or the client/user) adds a template and it would not take into account whether the template is used or not. 

It would be a lot more interesting to create that list automatically based on what templates are actually being used by pages that are, for instance, beneath a certain parent.

That way, the list is always up to date and does not display a template that is not actually being used by any published pages.

So, is that possible?

Perhaps I'm getting this all wrong but is this what you are looking for?

foreach ($templates as $template) {
    echo $template->name;
}

I think you're getting it wrong, and Joss wants this instead:

foreach ($pages->find("template=$page->template") as $p) {
    echo $p->name;
}

[arjen]

I stand corrected!

[Joss]

Oh, goody!

That means I can do something like

$postpages = $pages->find("parent=/posts/");

$templates = $pages->find("template=$postpages->template.....

or something like that to find all the templates used by a group of posts and then loop them out.

Probably not quite right, but I haven't got that far yet

foreach($templates as $template){
   $postsparent = $pages->get('/path/to/parent/');
   $cwt = $postparent->children("template=$template->name");
   if(count($cwt)){
     echo "$template->name: \n";
     foreach($cwt as $tp){
       echo "\t $tp->name \n";
     }
   }
}

i think this would list out the child pages of any parent grouped by which template they have. Not tested though, and not too sure if children("template=$template->name") is valid

I was just wondering if I need to check with this whether the pages are visible or not - obviously I dont want to list a template if it doesn't have published pages.

But then, I think the system should take that into account anyway.

it is valid. Though you could also just specify $template (without the ->name).

Any calls to a function that returns a PageArray (like $page->children(), $pages->find(), etc.) are going to exclude pages that are hidden, unpublished or otherwise inaccessible to the user. To make it include them, you can specify one of these:

• include=hidden -- includes hidden pages. 
• check_access=0 -- Includes pages the user doesn't have view access, as a result of role permissions.
• include=all -- includes all pages with no restrictions.

thanks for that, I had this question in the back of my head too~
