Showing all posts from different folders (merging collections)

The CMS Questions
1

I make posts in two folders, call them /a/ and /b/.

Is it possible on the index page to display all the posts from both of those folders, sorted by date?

If all posts have the same template you could use this:

$posts = $site->index()->filterBy('template', 'YOURTEMPLATE')

Otherwise you could merge two collections like this:


<?php
  $posts_a = $site->find('a')->children();
  $posts_b = $site->find('b')->children();
  $posts = new Pages(array($posts_a, $posts_b));
?>

Found here: Merge Collection of Pages

I’d go for the second option @flokosiol suggested, and to sort by date:

$posts = $posts->sortBy('date', 'desc'); //or asc, depending on what you want to achieve.

Oh yes, of course. I missed that … :wink:

Hey thanks @flokosiol and @texnixe, this looks perfect. :grinning:

I’m a little confused on the actual implementation of the code, do I somehow include it with a foreach statement like how I would on the individual pages?

You loop through the posts collection after merging:

<?php  
  $posts_a = $site->find('a')->children();   
  $posts_b = $site->find('b')->children();   
  $posts = new Pages(array($posts_a, $posts_b))->sortBy('date', 'desc'); ?>
  
 foreach($posts as $post) : ?>
  //do stuff
<?php endforeach ?>

I can’t seem to get the first part to work, the page just goes blank. In my case the two folders I put my posts in are called “buy” and “bought” ie (/content/buy/11223333-post/post.txt).

        <?php snippet('header') ?>
    
    <ul class="grid">
    
    	<?php
    	  $posts_a = $site->find('bought')->children();
    	  $posts_b = $site->find('buy')->children();
    	  $posts = new Pages(array($posts_a, $posts_b))->sortBy('date', 'desc'); ?>

<?php foreach($posts as $post) : ?>
    <li>
        post stuff...
    </li>
<?php endforeach ?>

   </ul>

 <?php snippet('footer') ?>

Have you turned on debugging in your config.php? What is the error?

One idea is that you can’t just use the string syntax “sortBy” like above, try putting it on a different line or put the new Pages thingy in parenthesis before adding sortBy().

$posts = new Pages(array($posts_a, $posts_b)); 
$posts = $posts->sortBy('date', 'desc');

Aha that was it! They had to be on separate lines. :stuck_out_tongue_winking_eye:

Thanks again for the help, I’ve been struggling the last couple days to find out how to merge collections in these flat-files CMSes, StaceyCMS had me pulling my hair out yesterday but Kirby looks perfect!

Yeah, Kirby is great, and just on a side note, Stacey does not seem to be under active development anymore. The last commit on Github was 2 years ago and the same is true for quite a few other flat-file CMS.

11

Oh for sure I have Kirby running for two other projects, love it.

But this is a super-super-side project so I was looking to avoid the 15€ and because I’ve used Stacey before, but to be honest, it’s totally worth it every time.

// EDIT
Nevermind. This was just me forgetting about looking out for captial letters in folder names…
Been too long since I worked with Kirby. Now it works perfectly!
