I often have similar boilerplate code in Twig:
{% if (somelongcond) %}
<div>
{% endif %}
<p>Some long content</p>
{% if (somelongcond) %}
</div>
{% endif %}
The problem with the above is if the condition is changed, it can be a maintenance nightmare, I also have to go look all the way down to find the matching if statement and see if the condition is the same.
An alternative is something like this:
{% if (somelongcond) %}
<div>
{% include 'content' %}
</div>
{% endif %}
{% include 'content' %}
But that requires creating a new file, which can become a mess if I need to do this many times.
Is there a better way to do the above.
There is a good example here: https://gist.github.com/jakedohm/39190ec533e69e83b9cee4bdf3898a60
Result:
{% set content %}
<p>Some long content</p>
{% endset %}
{% if somelongcond %}
<div>
{{ content }}
</div>
{% else %}
{{ content }}
{% endif %}
This is a bit shorter
{{ if somelongcond ? '<div>'|raw }}
<p>Some long content</p>
{{ if somelongcond ? '</div>'|raw }}
Then, if the same condition is repeated, you can maybe set it at the top of your file, then if you need to change it you only have to do it once.
{% if somelongcond %}
{% set cond = true %}
{% else %}
{% set cond = false %}
{% endif %}
{{ if cond ? '<div>'|raw }}
<p>Some long content</p>
{{ if cond ? '</div>'|raw }}

I'm using Twig in Views to rewrite output with condition.
{{ field_illus_lycee }}
{% if field_titre_pour_views is defined %}
{% if field_titre_pour_views is not empty %}
{{ field_titre_pour_views }}
{% endif %}
{% else %}
{{ title }}
{% endif %}
<span class="accroche-admin">{{ body }}</span>
I want to display field_titre_pour_views only if it exists and isn't empty, otherwise the regular title should be displayed. But at this point the regular title isn't displayed.Inspired by this
I don't understand which mistake I've made.
EDIT: correct code
{{ field_illus_lycee }}
{% if field_titre_pour_views is defined %}
{% if field_titre_pour_views is not empty %}
{{ field_titre_pour_views }}
{% else %}
{{ title }}
{% endif %}
{% else %}
{{ title }}
{% endif %}
<span class="accroche-admin">{{ body }}</span>
Sometimes, to ask is to find...this code do the trick:
{% if field_titre_pour_views |default %}
{{ field_titre_pour_views }}
{% else %}
{{ title }}
{% endif %}
Auto fixed :)
Hope it would help someone else.
I have an if/else condition in a twig template which switches the out tag of a block of code, however the inner block is the same. Is there a way to reduce the duplication without creating a separate file?
This is what I have at the moment:
{% if condition %}
<a href="">
{{ content }}
</a>
{% else %}
<span>
{{ content }}
</span>
{% endif %}
I was hoping to do something such as:
{% if condition %}
<a href="">
{% include mycontent %}
</a>
{% else %}
<span>
{% include mycontent %}
</span>
{% endif %}
{% mycontent %}
{{ content }}
{% endmycontent %}
Is such a thing possible?
If you don't want to use extra files you could use macro's :
{% import _self as macro %}
{% macro foo(content) %}
{{ content }}
{% endmacro %}
{% for condition in [0, 1, 0, 1, ] %}
{% if condition %}
{{ macro.foo('Bar') }}
{% else %}
<span>{{ macro.foo('Bar') }}</span>
{% endif %}
{% endfor %}

What you want to do has to be done using the normal syntax. an extra file. and include this file.
But if u want to do this without extra file. use the {% set variablecontent = "put content here" %} and then in your "{% mycontent %}" part u put {{ variablecontent }}
hope this helps
I need to place a twig template into my page and place another twig template inside it.
In page.twig:
{% embed "parent.twig" %}
{% block something %}
{% include "child.twig" %}
{% endblock %}
{% endembed %}
In parent.twig:
{% set array = ['', '', '']
%}
<div class="parent">
{% for i in array %}
<div class="parent__item">
{% block cardBoard %}
{% endblock %}
</div>
{% endfor %}
</div>
The problem is that the block doesn't work when its within a loop. I can edit page.twig all I like but I would rather not change parent.twig if possible as its consumed by other applications.
Why do you put a block inside a for loop ? You can't have 2 blocks defined with the same name.
In your case it will try to put this in your template 3 times :
<div class="parent__item">
{% block cardBoard %}
{% endblock %}
</div>
This will create a 500 server error :
The block 'cardBoard' has already been defined line '' in :parent.twig at line ''.
If you really want to have content depending on the values in your array, put the block opening and closing outside the for loop.
Like this for example :
{% set array = ['', '', '']%}
<div class="parent__item">
{% block cardBoards %}
{% for i in array %}
<div class="cardBoard{{ i }}>
</div>
{% endfor %}
{% endblock %}
</div>
i have this website http://sds-test.nowcommu.myhostpoint.ch/de (please use the "de" at the end) and the last link of the navigation "RECHENZENTRUM" does not works on desktop but works on mobile. How can i solve it? This is the twig code:
{% extends 'partials/base.html.twig' %}
{% set show_onpage_menu = header.onpage_menu == true or header.onpage_menu is null %}
{% macro pageLinkName(text) %}{{ text|lower|replace({' ':'_'}) }}{% endmacro %}
{% block javascripts %}
{% if show_onpage_menu %}
{% do assets.add('theme://js/singlePageNav.min.js') %}
{% endif %}
{{ parent() }}
{% endblock %}
{% block bottom %}
{{ parent() }}
{% if show_onpage_menu %}
<script>
// singlePageNav initialization & configuration
$('#navbar').singlePageNav({
offset: $('#header').outerHeight(),
filter: ':not(.external)',
updateHash: true,
currentClass: 'active'
});
</script>
{% endif %}
{% endblock %}
{% block header_navigation %}
{% if show_onpage_menu %}
<ul class="navigation">
{% for module in page.collection() %}
{% set current_module = (module.active or module.activeChild) ? 'active' : '' %}
<li class="{{ current_module }}">{{ module.menu }}</li>
{% endfor %}
{% set datacenter_page = page.find('/services/datacenter') %}
<li>{{ datacenter_page.menu() }}</li>
</ul>
{% else %}
{{ parent() }}
{% endif %}
{% endblock %}
{% block content %}
{{ page.content }}
{% for module in page.collection() %}
<div id="{{ _self.pageLinkName(module.menu) }}"></div>
{{ module.content }}
{% endfor %}
{% endblock %}
The 'rechenzentrum' link is rendered correctly, and copying the link location via right click gives a correct URL that opens a seemingly correct page. So the template rendering is fine.
The link has two onclick handlers attached to it, though. Probably one of them fails and thus prevents navigation. (The JS is minified so I did not try to debug it.)
I have
<div class="{{element.type == 'cover' ? 'cover-full' : 'fixed-width'}}">
<div class="element
{% if element.type == 'text' %}
element-text
{% elseif element.type =='image' %}
element-image
{% endif %}">
{% if element.type == 'text' %}
...
{% elseif element.type == 'image' %}
...
{% endif %}
</div>
As you can see I have to make the same if condition multiple times.
How can avoid to repeat every time the condition? I'm pretty new to Twig templating.
You will often have abit redundancy. But IMO it is a better practice to repeat HTML blocks instead of twig.
{% if element.type == 'text' %}
<div class="element element-text">
content
</div>
{% elseif element.type =='image' %}
<div class="element element-image">
content
</div>
{% else %}
{% include 'snippet.html' %}
{% endif %}
You have more valid and more readable HTML
If you change a condition you only have to change it one time
You could use {% include 'snippet.html' %} to reduce redundancy in HTML blocks
You can simplify your code:
{% if element.type in ['text','image'] %}element-{{element.type}}{% endif %}
You can use twig macro. On the top of that template add
{% macro element_class(type) -%}
{% if type in ['text','image'] %}element-{{type}}{% endif %}
{%- endmacro %}
{% from _self import element_class %}
And later:
<div class="{{element.type == 'cover' ? 'cover-full' : 'fixed-width'}}">
<div class="element {{ element_class(element.type) }}">
You can learn more about macros in Twig documentation.
