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 'node--unpublished',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 change the color of a button depending which home country the user is from. But my rendering does not work/ does not override the current css. Is this line of code correct?
{% if {{custom_attribute.${home_country}}} == 'DE'%}
<div class="button-right btn btn-next" style="background:#992B82 !important;">
<a><p> NEXT</p></a>
</div>
{% else %}
<div class="button-right btn btn-next" style="background: #F1287E !important;">
<a><p> NEXT</p></a>
</div>
{% endif %}
If anyone is familiar with Braze, liquid conditional rendering, and if it is possible. Im grateful for any answers!
Before creating this question, I've read all the question existing, and none of the answers has fixed my issue.
Well, I'm fetching a data from API, {{ album.image["3"]["#text"] }} - is the link to the .png file which I would like to set as background-image of the . Here is the example of my code:
<div class="album-grid">
<div *ngFor="let album of albums">
<div class="album"> <--! I want here to set a backgroundImage for each album-->
<h4>{{ album.name }},</h4>
<h5>by {{ album.artist.name }}</h5>
<p>{{ album.image["3"]["#text"] }}</p> <--! this is the link to .png file I'm getting from server -->
</div>
</div>
</div>
here is the solutions I've tried, but none of them helped me:
[style.backgroundImage]="album.image['3']['#text']"
[style]="backgroundImage: {{album.image['3']['#text']}"
[ngStyle]="{ 'backgroundImage': album.image['3']['#text'] }"
Link to my repo -> https://github.com/paslavskyi9roman/Spotilar
On a picture, you can see a grid of albums, with the album name, artist name, and link to album cover file which need to be a background image
click here
You are missing the url() part.
Try the following (as seen in your repository)
<div class="album" [ngStyle]="{ 'backgroundImage': 'url('+ album.image['3']['#text'] + ')'}">
<h4>{{ album.name }},</h4>
</div>
<h5>by {{ album.artist.name }}</h5>
</div>
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 have this piece of code inside Twig loops that will render beautiful color to every first letter of key=>value
<i class="avatar avatar-color-95 avatar-letter-c">{{ firstletter(message.firstname)}}</i>
But I want this to display color in dynamic way, different colors depending the length of the value
{% for message in pagination %}
{% set namecount = message.firstname | length %}
{#{ dump(namecount)}#}//outputs number(length)
<div class="container avatar">
<i class="avatar avatar-color-12 avatar-letter-c">{{ firstletter(message.firstname)}}</i>
{% endfor %}
I want to do it like this
<i class="avatar avatar-color-{{ namecount }} avatar-letter-{{firstletter(message.firstname)}}">
How do you do it? I tried to put qoutes between
"{{namecount}}"
and
"{{firstletter(message.firstname)}}
But it doesnt work. I cant find any docs for this in Twig docs,.How do you do it?
From the comments section...
You could just use <i class="avatar avatar-color-{{ message.firstname|length }} avatar-letter-{{ message.firstname|slice(0, 2) }}">.
Unless you are going to be using the variable again there's not much point in setting a variable rather than calling the filter/function inline.
Does anyone know how to render a dynamically generated block name using the Sonata Block Bundle? An example of what I am trying to achieve is:
page.html.twig:
<div class="content">
{{ sonata_block_render({
'name': '/content/blocks/{{ suffix }}'
}) }}
</div>
where suffix is a variable passed to the twig template, e.g. about-us. This allows me to use a single template for rendering all my CMS content. I have tried doing the above, but that doesn't seem to work.
You're already in twig context, that's why {{ }} didn't work. You'll need the string concatenation operator (~) like this:
<div class="content">
{{ sonata_block_render({
'name': '/content/blocks/' ~ suffix
}) }}
</div>
