Hyperlogos.org moves to D9

...as soon as I can get hosting... because my host is still stuck on PHP 7.4. This means that I'm still stuck with D7. But this blog is about converting my site from D7 to D9. I was able to preserve everything, it seems, down to text formats — but all of them were refusing to display because they had references to missing filters, so it made it look like none of my content was present.

Speaking of missing filters, many Drupal functions now refuse to run in an eval(), so I'm having to finally figure out how to produce modules to do some things that I've been doing with PHP snippets. The current (and I think only major) issue is image support, as there is no longer an img_assist module. I put multiple PHP versions with FastCGI on my system, so I currently have both the old and new sites running here, and I have hopes of brewing a solution.

Because I used to use the amazon module, I had some bad references to clean up. I had some odd errors like these:

[error]  A non-existent config entity name returned by FieldStorageConfigInterface::getBundles(): entity type: comment, bundle: comment_node_amazon, field name: comment_body  
[error]  A non-existent config entity name returned by FieldStorageConfigInterface::getBundles(): entity type: comment, bundle: comment_node_amazon_node, field name: comment_body  
[error]  A non-existent config entity name returned by FieldStorageConfigInterface::getBundles(): entity type: node, bundle: amazon, field name: body 

Long story short, I found a solution to the entity problem on the Drupal site.

Here's what I used to use to display img_assist links with, using customfilter module and the PHP option:

Match: /\[img_assist\|(.+?)]/

$elements = explode('|', $matches[1]);

$result = '(filter error or malformed img_assist tag)';

foreach ($elements as $element) {
  $parts = explode('=', $element);
  if ( $parts[1] != '' ) {
    $values[$parts[0]] = $parts[1];
  }
}

if ( $values[nid] ) {
  $mynode = node_load($values[nid]);
  if (!$mynode) {
    $result = "(cannot load image node)";
  } else {
    if ($mynode->node_image[$mynode->language][0]['uri']) {
      $path = $mynode->node_image[$mynode->language][0]['uri'];
    } else {
      $path = $mynode->node_image['und'][0]['uri'];
    }

    if ( $values[height] && $values[width] ) {
      $result = theme('image_style', array('style_name' => 'large', 'path' => $path, 'getsize' => FALSE, 'alt' => $mynode->title, 'attributes' => array('class' => 'img_assist', 'width' => $values[width], 'height' => $values[height])));
    } else {
      $result = theme('image_style', array('style_name' => 'large', 'path' => $path, 'getsize' => TRUE, 'alt' => $mynode->title, 'attributes' => array('class' => 'img_assist')));
    }
  }
  if ( $values[link] == 'node' ) {
    $result = l($result, 'node/'.$values[nid],array('html' => TRUE));
  }
}

return $result;

I also have the nigh-identical following for D7 image filter links, I'm not sure why I felt a need to replace the actual D7 module, but I clearly did. It doesn't have a D8/D9 version anyway.

Match: /\+) (.+?)]/

$nid = $matches[1];
$elements = explode(' ', $matches[2]);

$result = '(filter error or malformed image tag)';

foreach ($elements as $element) {
  $parts = explode('=', $element);
  if ( $parts[1] != '' ) {
    $values[$parts[0]] = $parts[1];
  }
}

if ( $nid ) {
  $mynode = node_load($nid);
  if (!$mynode) {
    $result = "(cannot load image node)";
  } else {
    if ($mynode->node_image[$mynode->language][0]['uri']) {
      $path = $mynode->node_image[$mynode->language][0]['uri'];
    } else {
      $path = $mynode->node_image['und'][0]['uri'];
    }

    if ( $values[height] && $values[width] ) {
      $result = theme('image_style', array('style_name' => 'large', 'path' => $path, 'getsize' => FALSE, 'alt' => $mynode->title, 'attributes' => array('class' => 'img_assist', 'width' => $values[width], 'height' => $values[height])));
    } else {
      $result = theme('image_style', array('style_name' => 'large', 'path' => $path, 'getsize' => TRUE, 'alt' => $mynode->title, 'attributes' => array('class' => 'img_assist'))); 
    }
  }
}

return $result;

Since PHP in customfilter is no longer a thing, I need to come up with a module that produces a real filter that does the same job. It still does some neat stuff, but not this any longer. I might try running the image filter D7 module through the module converter, though, just to see what happens. My image nodes made the trip, at least the ones I've checked on. Ideally, the module then goes on to convert both types of tag to something more modern.
