I have a content type that contains a field that is a reference to another node. I'm trying to include a field from the referenced node within the page for the main node, but I can't figure out how to add that. Here's how I'm getting the value within my theme:
function mytheme_preprocess_node(array &$variables) {
$node = $variables['node'];
if ( $node->get('field_testimonial') ) {
$referenced_nodes = $node->get('field_testimonial')->referencedEntities();
if ( count($referenced_nodes) > 0 ){
$referenced_node = $referenced_nodes[0];
//this is providing the value I want. how can I add that back to my page?
error_log($referenced_node->body->value);
}
}
}
Please help me add that value back to my variables so I can use it in my theme! Thank you for your help.
Just do the following
$variables['referenced_body'] = $referenced_node->body->value;
In your Twig-Template you can do this:
{{ referenced_body }}
Why are you doing with code ? it can configure form admin
Go to admin/structure/types/manage/article/display and manage your desire format to display the reference node.
Thanks

Building a site in Drupal 8, using classy subtheme. Run into a puzzling theming issue - adding body class to html.html.twig based on a taxonomy term on that node.
Themers use this to customize page display, in my case using it to define a few sections of my site so I can change color and format.
I have tried some preprocess functions I saw on google but to no result.
Has anyone else run into and solved this issue?
Use this to get all fields of the node and check for whatever you need:
\Drupal::service('current_route_match')->getParameter('node')->toArray();
In your .theme file you can use the html preprocess hook:
function your_theme_preprocess_html(&$variables) {
$body_classes = [];
$nodeFields = \Drupal::service('current_route_match')->getParameter('node')->toArray();
// if something, then set $body_classes to something.
$variables['attributes']['class'] += $body_classes;
}
And then in your html twig template add the attributes to the body element:
<body{{ attributes }}>
Hope this helps.
With the answer of Frank Drebin I get a PHP fatal error (Unsupported operand types) with the "+=" operand. If you want to add the node ID and node type to your body class, you can use this code for example:
// Add the node ID and node type to the body class
$body_classes = [];
$nodeFields = \Drupal::service('current_route_match')->getParameter('node')->toArray();
if (is_array($nodeFields) && count($nodeFields) > 0) {
if (isset($nodeFields['nid'])) {
$body_classes[] = 'node-' . $nodeFields['nid'][0]['value'];
}
if (isset($nodeFields['type'])) {
$body_classes[] = $nodeFields['type'][0]['target_id'];
}
}
$variables['attributes']['class'] = $body_classes;
In some Wordpress Posts I want to show the featured thumbnail image shown:
fearless_post_thumbnail(); //located in content.php of template
But in some posts I want to hide that thumbnail, In that case I would like to create a custom
field (hide_thumb = 1 )
in posts where I want to hide it:
Question: Which condition should I wrap around:
fearless_post_thumbnail(); // it shows thumbnail.
Thank you
not sure I understand your question, but it sounds like you want to do this:
if ( $hide_thumb != 1 ) {
fearless_post_thumbnail();
}
If your custom field, $hide_thumb, is set to TRUE or 1, then your thumbnail function will not execute.
The other answer here assumed you had already retrieved the value of of your custom field. As per http://codex.wordpress.org/Function_Reference/get_post_custom,
$custom_fields = get_post_custom();
$hide_thumb = $custom_fields['hide_thumb'];
if ( $hide_thumb[0] != 1) {
fearless_post_thumbnail();
}
I have taxonomy terms hierarchy and I am using them as a filter in a view. It is showing hierarchy in the selectbox, but child terms appearing with hyphen(-). I have tried to drop hyphen in form alter, and I did, but I couldn't replace it blank space.
if ($form_id == 'views_exposed_form') {
$i = 0;
foreach ($form['field_region_tid']["#options"] as $op) {
foreach ($op->option as $key => $arr) {
if ($arr != null) {
$form['field_region_tid']["#options"][$i]->option[$key] = str_replace("-"," ", $arr);
}
}
$i++;
}
}
How can I put blank space at the beginning of the child options. Or should I do some other way?
Thanks!
From the form_id I get that it is a form generated by views. If so, the code inside the if condition never gets called because your module is executed after the views module due to the weight of both modules. To fix that:
Open your database manager (PhpMyAdmin in most cases) and open system table.
Then change the weight for your module to something larger than 10, because it is the default weight for the views module and you need you module to be executed after the views module.
Hope this helps... Muhammad.
if the problem is when your hook is called the answer lies in
hook_module_implements_alter()
but it is not as you say. Your code looks fine,
Have you tried
str_replace("-"," ", $arr);
?
Currently I'm using the code as suggested in this answer. Which is the following:
function simalr_preprocess_image(&$variables) {
if ($variables['style_name'] == 'request-background') {
$variables['attributes']['class'][] = 'pixastic';
$variables['attributes']['class'][] = 'pixastic-blurfast(amount=1)';
}
}
This works fine except for the fact that I get the following error message on a page which doesn't have an Image with the 'request-background' style:
Notice: Undefined index: style_name in simalr_preprocess_image() (line 46 of /var/www/vhosts/simalr.com/httpdocs/sites/all/themes/simalr/template.php).
I only want this piece of code used on a specific content type (namely 'request'). In which way do I have to adjust the code in my template.php file in order to just use it on a page which is only of a certain content type?
You can still work with your code but use isset function. This will remove the warning.
If you want to do it just for a specific content type use menu_get_object function in drupal. This function will return the node for you if it's a node page.
Example:
$node = menu_get_object();
if ($node->type == 'story') {
// TODO
}
Hope this helps.
I'm trying to allow users to update head titles and meta descriptions for each page. I thought that an easy way to achieve this would be to add a field to the 'Basic page' content type for the page title, then check if that field is not empty in html.tpl.php and if it is not, override $head_title with this user-defined value.
However, it appears that the $node variable is not available in html.tpl.php. Can anyone suggest a way for me to make this data available in this template file, or alternatively, alter $head_title before it is sent to html.tpl.php? Thanks for reading.
Taken in part from this thread that I found: http://drupal.org/node/1041768...
In your template.php, you can do the following:
function yourtheme_preprocess_html(&$variables) {
// If on an individual node page, add the node type to body classes.
if ($node = menu_get_object()) {
$variables['head_title'] = $node-> // find your cck field here
}
}
Bit messy, but would work:
if(arg(0) == 'node' && !empty(arg(1))) {
$node = node_load(arg(1));
}
However, you might prefer http://drupal.org/project/metatags_quick (an interrim module until the full http://drupal.org/project/metatags is finished).
