Today I've try to add image_field in "Page Title" block.
I don't know if it's possible ?
If it isn't possible, it is possible to add field_image in twig template ?
Tnks.
The below may help you. First im adding a theme suggestion for page_title, so that i can control the place where i have to over ride the template. I am adding node_type - as suffix to the template.
Then i am adding the preprocess function- make sure you replace the signature with the type you want "news" at the end should be replaced with your content type from the first function.
In the second function i am fetching a field called subtitle, and adding the value to variables so that it is available in the template.
function mytheme_theme_suggestions_alter(array &$suggestions, array &$variables, $hook) {
if($hook === 'page_title') {
if($node = \Drupal::routeMatch()->getParameter('node')){
$node_type = $node->getType();
// suggestion must use _ and __ as per convention.
$suggestions[] = 'page_title__'.$node_type;
}
}
}
function mytheme_preprocess_page_title__news(&$variables) {
if ($node = \Drupal::routeMatch()->getParameter('node')) {
try {
if ($node->get('field_subtitle') && !$node->get('field_subtitle')->isEmpty()) {
$variables['sub_title'] =
$node->get('field_subtitle')
->get(0)
->get('value')
->getValue();
}
}catch(Exception $e){
\Drupal::logger('mytheme')->error($e);
}
}
}
Now in the template you will sub_title available in the template file, in my case it was page-title--news.html.twig - copied from page-title.html.twig and added respective variable.
