XF 2.0 Get all prefixes grouped by forum

[LPH]

The following code loops through and gets all the prefix titles.

/** @var \XF\Entity\Forum $node */
$nodes = \XF::app()->finder( 'XF:Forum' )->fetch();

foreach ( $nodes AS $node ) {
   $prefix_cache = $node->prefix_cache;

   foreach ( $prefix_cache AS $prefix_id ) {
      $prefixTitle = \XF::app()->templater()->fn( 'prefix_title', [ 'thread', $prefix_id ] );
      echo $prefixTitle . '<br />';
   }
}

I don't like the nested loop and the final structure relies on dropdown select:

ForumA Title
-- Prefix1 Title
-- Prefix2 Title
ForumB Title
-- Prefix2 Title
-- Prefix4 Title

In other words, the forum is listed and the possible prefixes are listed below it.

Question 1
Is there a better way to grab the forum title then the possible prefixes for that forum? I saw a getPrefixesGrouped()

Question 2
Is there a way to organize these in the same order requested in the XenForo panel?

If nothing else, I figured out how to use array_column:

/** @var \XF\Entity\Forum $node */
$nodes = \XF::app()->finder( 'XF:Forum' )->fetch();
$prefix = array_column( $nodes->toArray(), 'prefix_cache' );

\XF::dump($prefix);

This leads to



Pulling the forum title and prefix title from this information still eludes me. Oh well. If anyone has any suggestions then please let me know.

/** @var \XF\Repository\ThreadPrefix $nodeRepo */
$nodeRepo = \XF::repository('XF:ThreadPrefix');
$nodeTree = $nodeRepo->getPrefixListData();

\XF::dump($nodeTree);

This provides an arrayCollection.

/** @var \XF\Entity\Forum $node */
$nodes = \XF::app()->finder( 'XF:Forum' )->fetch();

echo '<select id="xenword_prefix_id" name="xenword_prefix_id" class="postform" >';

echo '<option value="">Select A Prefix</option>';

foreach ( $nodes AS $node ) {

   echo $node->title , '<br />';

   foreach ( $node->prefix_cache AS $prefix_id ) {

      echo '<option value="' . $prefix_id . '"';

      if ( $prefix_id == $prefixId ) {
         echo 'selected="selected"';
      }

      echo '<span style="margin-left:20px;">' . \XF::app()->templater()->fn( 'prefix_title', [ 'thread', $prefix_id ] ) . '</span>';

      echo '</option>';
   }
}

echo '</select>';

This almost works. The titles of the Forums are not showing because they are outside the option value. I haven't figured out how to get that part to work.

Got it !

/** @var \XF\Entity\Forum $node */
$nodes = \XF::app()->finder( 'XF:Forum' )->fetch();

echo '<select id="xenword_prefix_id" name="xenword_prefix_id" class="postform" >';

echo '<option value="">Select A Prefix</option>';

foreach ( $nodes AS $node ) {

   echo '<option value="">' . $node->title . '</option>';

   foreach ( $node->prefix_cache AS $prefix_id ) {

      echo '<option value="' . $prefix_id . '"';

      if ( $prefix_id == $prefixId ) {
         echo 'selected="selected"';
      }

      echo ' class="_depth' . $node['depth'] . '">';

      echo str_repeat('&nbsp;', $node['depth'] * 4 );

      echo '<span style="margin-left:20px;">' . \XF::app()->templater()->fn( 'prefix_title', [ 'thread', $prefix_id ] ) . '</span>';

      echo '</option>';
   }
}

echo '</select>';

And it works.
