I'm trying to display a number next to each article with the following code in Kirby.

      <?php 
          $count = 0;
          foreach($page->children()->visible()->flip() as $article):
          $count++
      ?>

      <article>
        <span="numeral"><?php echo $count; ?></span>
        <h1><a href="<?php echo html($article->url()) ?>"><?php echo html($article->title()) ?></a></h1>
        <time pubdate="pubdate"><?php echo $article->date('n/j/Y') ?></time>
      </article>
      <?php endforeach ?>

However, it's outputting like this
1 Latest Article
2 Older Article

I need it to output like this
2 Latest Article
1 Older Article

Maybe set the counter to the highest number, and count down.

I took a peek at the Kirby API cheat sheet I came up with this.

<?php 
          $count = $page->count();
          foreach($page->children()->visible()->flip() as $article):
          $count--;
      ?>

<?php 
    $articles = $page->children()->visible()->flip();
    $count = $articles->count();
    foreach($articles as $article):
  ?>
      <article>
        <span="numeral"><?php echo $count; ?></span>
        <h1><a href="<?php echo html($article->url()) ?>"><?php echo html($article->title()) ?></a></h1>
      </article>
<?php
      $count--;
    endforeach
  ?>

@hotpink I had to change your code as it was counting all the pages, I think (it started from 16).

  $count = $page->children()->count();

This echos out 0 for the first article where I need it to echo out 1.

BenWalker

@hotpink is correct, but the page count will end in zero. Subtract at the end of the loop to end with one.

Nice @benwalker. Thank you!

Edit: Also, thank you @hotpink

BenWalker

Actually, scrap that. My code is the one to use :-)

... I think
