Hi folks! A while back, Bastian was kind enough to help me set up my archive page: Archive - Hicks.design.
I want to change the order of posts within each year, so that they’re in descending order. I’ve tried a few methods such as adding ->flip() but I don’t know what I’m doing.
Here’s the template code, edited for brevity :
<?php foreach ($years as $year): ?>
<div class="year">
…
<div class="archives">
<?php foreach ($year['posts'] as $post): ?>
<div>
<p class="posted"><time><?= $post->date()->toDate('d M') ?></time></p>
<a href="<?= $post->url() ?>" rel="bookmark">
<?= $post->title() ?>
</a>
</div>
<?php endforeach ?>
</div>
</div>
<?php endforeach ?>
Strange, no reason why flip shouldnt work on the foreach loops
<?php foreach ($years->flip() as $year): ?>
<div class="year">
…
<div class="archives">
<?php foreach ($year['posts']->flip() as $post): ?>
<div>
<p class="posted"><time><?= $post->date()->toDate('d M') ?></time></p>
<a href="<?= $post->url() ?>" rel="bookmark">
<?= $post->title() ?>
</a>
</div>
<?php endforeach ?>
</div>
</div>
<?php endforeach ?>
Although im not sure where $year['posts'] came from. Is there a controller or something matching the template? It might be best to do the flip in the controller rather than in the template.
Thanks James - putting flip after the <?php foreach ($year['posts'] results in the error:
Call to a member function flip() on array
The controller looks like this:
<?php
return function ($page) {
$articles = pages(['journal', 'troika'])->children()->listed();
$years = [];
foreach ($page->children()->flip() as $year) {
$years[$year->slug()] = [
'summary' => $year,
'posts' => []
];
}
foreach ($articles as $article) {
$year = $article->date()->toDate('Y');
if (isset($years[$year])) {
$years[$year]['posts'][] = $article;
}
}
return [
'articles' => $articles,
'years' => $years
];
};
This + the above template takes all my posts from the Journal and Troika sections and presents them in a list, broken up by year (with other bits of information). The Year order is flipped, but not the posts.
Ah yes thats because its not a collection.
I think you probably need to take the flip out of the template and in the controller add another flip() the to the middle for each loop
foreach ($articles->flip() as $article) {
$year = $article->date()->toDate('Y');
if (isset($years[$year])) {
$years[$year]['posts'][] = $article;
}
}
Spot on, thanks so much for your help James!
