I am trying to show only upcoming events from a list of events. Below is how I have tried to display.
<div class="row">
{% for item in items %}
{% if item.content['#node'].field_event_type.getValue()|first.value == 'upcoming' %}
<div class="col">{{item.content}}</div>
{% endif %}
{% endfor %}
</div>
But the output rendering is, the second event is displaying after the row div like below. I don't understand how this is happening as the for loop is inside the row div
<div class="row">
<div class="col"> content </div>
</div><div class="col"> content </div>
Expected output
<div class="row">
<div class="col"> content </div>
<div class="col"> content </div>
</div>
Twig does lots of things:
loading (open your Twig content)
parsing (create a parse tree from your Twig content)
compiling (browse that tree to create a php file)
caching (store the php file somewhere to avoid recompile it next time)
executing (execute the generated php file)
When a {% for %} is detected during parsing, Twig calls the token parser recursively until it finds {% endfor %} and builds a token tree. In your case, it would look like:
root
|
--- string
|
--- for
| |
| --- if
| |
| --- string
|
--- string
Then, Twig compiler crosses over that tree recursively and generates the corresponding php code. In that way, the following Twig loop:
{% for i in 1..5 %}
Value = {{ i }}
{% endfor %}
Compiles to this in PHP:
// line 1
$context['_parent'] = $context;
$context['_seq'] = twig_ensure_traversable(range(1, 5));
foreach ($context['_seq'] as $context["_key"] => $context["i"]) {
// line 2
echo "Value = ";
echo twig_escape_filter($this->env, $context["i"], "html", null, true);
}
$_parent = $context['_parent'];
unset($context['_seq'], $context['_iterated'], $context['_key'], $context['i'], $context['_parent'], $context['loop']);
$context = array_intersect_key($context, $_parent) + $_parent;
As you can see, a {% for %} is no more than a simple foreach and as Twig tokens are stored into a tree, it is by design not possible to display contents located below a pair of open/close tags.
The only possibility I can see is that one of the tag you're using in Twig is playing with output buffering, and one of the methods you're using in your loop breaks the ob stack (like a ob_get_clean() without any ob_start() for example, that have been open previously).
My advice is to grep your twig file name into your cache directory (eg: grep -Ri 'test.twig' cache/) in order to see that file compiled to PHP, to understand exactly what it does, and debug it.
Instead of filtering your content in twig, filter the results in your Drupal view.
In the "filter criteria" on your view, select the field_event_type field and set it "is equal to" and select/add 'upcoming' as the option.
If you filter in the view, you don't have to mess with the twig template.

I want to display S1 only instead of season 1. Thus I need to truncate season and put only 1 and add "S" at the front.
<a href="{% url 'season_detail' slug=all_episode.season.slug %}">
{{ all_episode.season}}
</a>
How do I truncate the word "season"?
Edit:
Here's what I did again
I created templatetag folder inside my app
then added init.py and seasonify.py
and inside seasonify.py I added
from django import template
register = template.Library()
#register.filter
def seasonify(value):
return value.replace('season', 'S')
then inside my template
I added
{% load seasonify %}
and {% episode.season|seasonify %}
Your best bet is to write a custom template filter. The logic is simple:
#register.filter
def seasonify(value):
return value.replace('season', 'S')
then simply use it in your templates:
{{ all_episode.season | seasonify }}
See Django docs for details on where to put this code.
I have a content type with a field field_gallery that has multiple images.
I would like to get all these images printed in my twig file: page--front.html.twig. So i want to get these images in my frontpage and not only in their nodes. So far i could get them in their nodes with
{{ file_url(node.field_image.entity.fileuri) }}
but not somewhere else (of course since its using node). Is this possible?
Should i create a preprocessor function for page? Any guidance for this?
Yes, This is possible. This question is have two sub tasks :
1) Creating page--front.html.twig file
For creation of this twig file, you'll have to clone file i.e. page.html.twig and rename it with page--front.html.twig
2) Fetch Raw values of Image fields
You need to update code in my .theme file:
function THEMENAME_preprocess_node(&$variables) {
if ($variables['node']->field_image->entity) {
$variables['image_url'] = $url = entity_load('image_style', 'medium')->buildUrl($variables['node']->field_image->entity->getFileUri());
}
}
Then in page--front.html.twig file I have this:
{% for item in image_url %}
<div class="featured-thumb">
<img src="{{ item }}"/>
</div>
{% endfor %}
New user of D8 : my problem is to access to fields in a view or even in general with Drupal 8.
As we could do with ACF in Wordpress.
a {{ kint() }} crash my chrome but works with Firefox to explore the content var.
Unfortunately I do not managed to find and use fields' variables in my view.
I create a new view, which actually display the last three articles. These are well displayed in ugly list but I want to extract fields to put them in a custom html integration.
I create and use a new template for the view :
x node--view--liste-des-actualites--page-2.html.twig
In a custom parent :
x node--page-accueil.html.twig
But when I try to kint() content in my node--view--liste-des-actualites--page-2.html.twig, I have the custom field of the page (Page accueil) and can't find the article's one.
I managed to do it in my custom page but not in this view.
{%
set classes = [
'node',
'node--type-' ~ node.bundle|clean_class,
node.isPromoted() ? 'node--promoted',
node.isSticky() ? 'node--sticky',
not node.isPublished() ? 'node--unpublished',
view_mode ? 'node--view-mode-' ~ view_mode|clean_class,
'clearfix',
]
%}
{{ attach_library('classy/node') }}
<article{{ attributes.addClass(classes) }}>
<div{{ content_attributes.addClass('node__content', 'clearfix') }}>
{{ content }}
<div class="col-lg-4 col-md-4 col-sm-4 col-xs-4">
<a href="{{ LINK_VAR }}" class="bloc-type">
<div class="categ categ_projet">{{ CATEGORY_VAR }}</div>
<div class="img"> <img src="{{ IMAGESRC_VAR }}" alt=""> </div>
<span class="wrapper">
<p class="date">{{ DATE_VAR }}</p>
<h3>{{ TITLE_VAR }}</h3>
</span>
</a>
</div>
</div>
</article>
EDIT
I managed to guess some fields but this is definitely not a good way to find variables..
{{ node.label }} + {{ content.field_tags }} (But I do not want a rendered one, I just want the text/value)
if you use kint(); to debug large arrays can crash your browser.
I would suggest to use the devel module https://www.drupal.org/project/devel. With devel you can debug your arrays inside of the Drupal8 UI for each content type, block or view.
In my case i use the UI of devel (additional tab on each content). in the module settings, you can chose how devel debugs, the error handling and the output.
As the OP commented it is possible to use a preprocess to display the array on your site:
function <themename>_preprocess_page(&$variables) {
dpm($variables);
}
I'm trying to show some object properties stored on the database. I've got the controller, the Entity, and the view. I'get no excepctions but I can't see the object properties.
Controller:
/**
* #Route ("/ov", name="ov")
*/
public function select(){
$a=$this->getDoctrine()->getRepository('AppBundle:PC')->find(2);
if(!$a){
throw $this->createNotFoundExcepction('No PC');
}
return $this->render('PcDetailed.html.twig', array('pcs' => $a));
}
View:
{% extends 'master.html.twig' %}
{% block divCentral %}
<div class="row">
<p>Nom del pc</p>
<div class="small-6 small-centered columns">
{% for pc in pcs %}
<p>{{ pc.nom }}</p>
{% endfor %}
</div>
</div>
{% endblock %}
Edit:
Finally, like Chris says, the problem is 'cause on the View I'm using I'm trying to iterate is an object, not an array. That's why doesn't work.
That's the way I must do it:
return $this->render('PcDetailed.html.twig', array('pcs' => array($a)));
In your controller you get the PC with id 2 and pass it to the view.
In the view you are now trying to iterate over this object. I have no idea what TWIG does when you try to iterate over something that is not an array or a collection but maybe it just fails silently.
To fix it, change your controller code to send an array to the view:
return $this->render('PcDetailed.html.twig', array('pcs' => array($a)));
Hie I am trying to get the synopsis and other items like author and published date printed. But I am Able to achieve this only with certain search terms, an error occurs with other words or terms
Key "description" for array with keys "title, subtitle, authors, publishedDate, industryIdentifiers, readingModes, pageCount, printType, categories, maturityRating, allowAnonLogging, contentVersion, imageLinks, language, previewLink, infoLink, canonicalVolumeLink" does not exist.
I am using symfony and twig. this is what the twig file looks like :
{% for item in items %}
<article>
<img src="{{ item.volumeInfo.imageLinks.thumbnail}}"/>
<h4>{{ item.volumeInfo.title}}</h4>
{{ item.volumeInfo.description }}
<strong> {{ item.volumeInfo.publishedDate }}</strong><br/>
<b>{{ item.volumeInfo.authors | join }}</b>
</article>
What am I doing wrong? why does this work only sometimes ? how can I make it work correctly all the time?
class GoogleBooksController extends Controller
{
public function getVolumeAction($title)
{
$client =new client();
$response = $client- >get("https://www.googleapis.com/books/v1/volumes?q=$title");
$data=$response->json();
$items=$data['items'];
return $this->render('BookReviewBundle:GoogleBooks:volume.html.twig', array('items'=>$items
// ...
)); }
Thanks
I belive the description field is not mandatory, so you can do follow
{% if item.volumeInfo.description is defined %}
{{ item.volumeInfo.description }}
{% endif %}
