How can I display all tags?

[kodersha]

Hello. How I can show all tags from blog posts on my homepage?

[schulle4u]

Simply enter 0 for the PagesMax parameter in your [blogtags] shortcut, e. g. [blogtags /blog/ 0].

How I can show it with html/php in my layout/home.html?

With the API you have access to all pages. It's a little bit more work to show tags, since each page can have multiple tags, which means you probably want to split page meta data into individual tags. I checked the API documentation, looks like there's no example you can simply copy/paste.

As a starting point, see function getShorcutBlogtags() in file blog.php of the blog extension.

With the latest API you can group/divide a page collection into multiple smaller collections.

Example 1 - Layout file to show tags with ascending name, A-Z:

<?php $this->yellow->layout("header") ?>
<div class="content">
<div class="main" role="main">
<h1><?php echo $this->yellow->page->getHtml("titleContent") ?></h1>
<?php echo $this->yellow->page->getContentHtml() ?>
<?php $pages = $this->yellow->content->index()->filter("layout", "blog")->sort("published", false) ?>
<?php $this->yellow->page->setLastModified($pages->getModified()) ?>
<ul>
<?php foreach ($pages->group("tag") as $tag=>$collection): ?>
<li><?php echo htmlspecialchars($tag)." (".count($collection).")" ?></li>
<?php endforeach ?>
</ul>
</div>
</div>
<?php $this->yellow->layout("footer") ?>

Example 2 - Layout file to show tags with descending count, highest first:

<?php $this->yellow->layout("header") ?>
<div class="content">
<div class="main" role="main">
<h1><?php echo $this->yellow->page->getHtml("titleContent") ?></h1>
<?php echo $this->yellow->page->getContentHtml() ?>
<?php $pages = $this->yellow->content->index()->filter("layout", "blog")->sort("published", false) ?>
<?php $this->yellow->page->setLastModified($pages->getModified()) ?>
<ul>
<?php foreach ($pages->group("tag", false, "count") as $tag=>$collection): ?>
<li><?php echo htmlspecialchars($tag)." (".count($collection).")" ?></li>
<?php endforeach ?>
</ul>
</div>
</div>
<?php $this->yellow->layout("footer") ?>

The method pages->group() lets you group a page collection by any page setting. Hope this helps.

I like it! 🎉

My code before:

<?php $this->yellow->layout("header") ?>

<h1><?php echo $this->yellow->page->getHtml("titleContent") ?></h1>
<?php echo $this->yellow->page->getContentHtml() ?>

<?php $pages = $this->yellow->content->index()->filter("layout", "blog")->sort("published", false) ?>
<?php
  $tags = array();
  $recents = null;
  $recentCounter = 0;
  foreach ($pages as $page) {
    if ($recentCounter++<5) {
      $recents .= "<li><a href=\"".$page->getLocation(true)."\" class=\"nav-link\">".$page->getHtml("title")."</a></li>";
    }

    if ($page->isExisting("tag")) {
        foreach (preg_split("/\s*,\s*/", $page->get("tag")) as $entry) {
            if (!isset($tags[$entry])) $tags[$entry] = 0;
            ++$tags[$entry];
        }
    }
  }
?>

<nav class="tags_nav">
    <?php
      $output = null;
      if (count($tags)) {
        uasort($tags, "strnatcasecmp");
        uksort($tags, "strnatcasecmp");
        $output .= "<ul>\n";
        foreach ($tags as $key=>$value) {
          $output .= "<li><a href=\"".$this->yellow->page->getBase()."/".$this->yellow->toolbox->normaliseArguments("tag:$key")." \" title=\"Tag: ".$key."\" aria-label=\"Tag: ".$key."\" role=\"button\" class=\"post_tag\">".$key." <sup><strong><sup>".$value."</sup></strong></sup></a></li>";
        }
        $output .= "\n</ul>\n";
      }
      echo $output;
    ?>
</nav>

<?php $this->yellow->layout("footer") ?>

and after:

<?php $this->yellow->layout("header") ?>

<h1><?php echo $this->yellow->page->getHtml("titleContent") ?></h1>
<?php echo $this->yellow->page->getContentHtml() ?>

<?php $pages = $this->yellow->content->index()->filter("layout", "blog")->sort("published", false)->limit(20) ?>

<nav class="tags_nav">
  <ul>
    <?php foreach ($pages->group("tag") as $tag=>$collection): ?>
    <li>
      <a role="button" class="post_tag" title="Tag: <?php echo strtolower(htmlspecialchars($tag)) ?>" aria-label="Tag: <?php echo strtolower(htmlspecialchars($tag)) ?>" href="<?php echo $this->yellow->page->getBase() . "/" . $this->yellow->toolbox->normaliseArguments("tag:$tag") ?>">
        <?php echo htmlspecialchars($tag) . " <sup><strong><sup>" . count($collection) . "</sup></strong></sup>" ?>
      </a>
    </li>
    <?php endforeach ?>
  </ul>
</nav>

<?php $this->yellow->layout("footer") ?>

Top work!
