This article shows you how to create Token Drupal to return absolute URL and image URL path of article content type content without language prefix.
Follow the instructions below:
Create custom_token.info.yml file:
name: Custom Token
type: module
description: "Example How to create custom token"
package: Custom
core: 8.x
core_version_requirement: ^8 || ^9 Create custom_token.module file:
The first thing we’ll need in this file is, hook_tokens_info() This is where we’ll define our tokens for Drupal. Which will make your new token available in UI.
In the second half of the code, the hook_tokens() function actually makes the token perform its desired function.
<?php
use Drupal\Core\Render\BubbleableMetadata;
use Drupal\image\Entity\ImageStyle;
/**
* Implements hook_token_info()
* @return array
*/
function custom_token_token_info()
{
$info['tokens']['site']['absolute_url'] = array(
'name' => t('Absolute URL'),
'description' => t('Url of the site, no language prefix garanted'),
);
$info['tokens']['site']['custom_image_token'] = array(
'name' => t("customimagetoken"),
'description' => t("Custom image token.")
);
return $info;
}
/**
* Implements hook_tokens()
* @param $type
* @param $tokens
* @param array $data
* @param array $options
* @param \Drupal\Core\Render\BubbleableMetadata $bubbleable_metadata
* @return array
*/
function custom_token_tokens($type, $tokens, array $data, array $options, BubbleableMetadata $bubbleable_metadata)
{
$replacements = array();
global $base_root;
foreach ($tokens as $name => $original) {
switch ($name) {
case 'absolute_url':
$replacements[$original] = $base_root;
break;
case 'custom_image_token':
if($node->getType() == 'article'){
if(isset($node->get('field_image')->entity)){
$image_style = 'large';
$style = ImageStyle::load($image_style);
$url_final = $style->buildUrl($node->get('field_image')->entity->getFileUri());
}
}
$replacements[$original] = $url_final;
break;
}
}
return $replacements;
}
Clear your Drupal 8 caches, and then your new token will be available in UI.
Next steps
Clear your Drupal 8 caches. To do this I use this Drush command: drush cr if you don’t currently use Drush, I highly recommend using it, or the Drupal Console.
Now, go back to your site, and you should be able to see the new custom token.
I hope you found this article useful. let me know if you have any questions and I’ll be happy to answer them.
