Twig newbie here :) And I'm using WordPress.
In a .twig file, I can display the category.slug this way:
{% for category in post.terms('category') %}
{{ category.slug }}
{% endfor %}
But how do I use an if construct with the category.slug?
I.e., I want to display the category if the post is in the category in-the-news. This obviously doesn't work:
{% for category in post.terms('category') %}
{% if category.slug == in-the-news %}
In The News
{% else %}
Other Category
{% endif %}
{% endfor %}
This is twig version is 1.34. Fiddle here from Matteo: https://twigfiddle.com/89t9gr
This works. I think the issue in my localhost and Twig v1.34 was having no quotes around the category slugs. And, for me, {% for category in categories %} does not work and does not throw an error.
{% for category in post.terms('category') %}
{% if category.slug == "in-the-news" %}
In The News
{% elseif category.slug == "videos" %}
Video
{% else %}
All Else
{% endif %}
{% endfor %}

This code does not work.
{% if url == 'example.com/categoty' %}
some text
{% endif %}
How to do this?
I assume you don't have url variable assigned. There is a global parameter for that:
{% if app.request.requestUri == '/categoty' %}
some text
{% endif %}
{% if 'mysite/news' in url %}
some text
{% endif %}
So I have Twig running on top of Symfony 2.7. In the output html I'd like to have a few modules of text and in the last module I want some summary from all the previous ones (some data from all the previous modules' Entities) and I figured I'd append these summaries to a global variable while generating modules themselves to avoid a second loop. The code I'm using:
{% extends 'base.html.twig' %}
{% set list = '' %} {# HERE I SET A GLOBAL VAR #}
{% block body %}
<section>
<h2>{% trans %}MODULES{% endtrans %}</h2>
{% for m in plan.Modules %}
{{- block('module') -}}
{{ list }} {# HERE JUST FOR TESTING - IT'S EMPTY #}
{% endfor %}
</section>
{{ list }} {# HERE I WANT IT DISPLAYED, YET IT'S EMPTY :( #}
{% endblock %}
{% block module %}
<h3>{{ m.Module.title }}</h3>
{# HERE SOME MODULE TEXT I GET FROM COMPLICATED RELATIONS #}
{% if m.Module.list %}
{% set temp %}
{{ m.Module.shortTitle }}<br/>
{% endset %}
{% set list = list~temp %}
{% for l in m.Module.list %}
{% set temp %}
{{ l }}
{% endset %}
{% set list = list~temp %}
{% endif %}
{% endfor %}
{% endif %}
{{ list }} {# HERE IT'S WORKING #}
{% endblock %}
Any ideas?
On a clients homepage they want 'all the products' listed with a load more button at the bottom.
There are four categories and each has a different color associated. I want to pull in all the products by date listed order and apply a class to the product depending on the category.
Currently I have
{% assign collection = collections.all %}
{% for product in collection.products %}
{% if collection.handle == 'clothing' %}
<div class="theme-red overview-item">
{% elsif collection.handle == 'pictures' %}
<div class="theme-green overview-item">
{% elsif collection.handle == 'posters' %}
<div class="theme-blue overview-item">
{% elsif collection.handle == 'other' %}
<div class="theme-beige overview-item">
{% else %}
<div class="theme-none overview-item">
{% endif %}
...
</div>
{% endfor %}
This is currently picking up as theme-none and that's because I'm calling collections.all?
How do I get all the products shown regardless of a collection and then apply do something as per the if/else statements like above.
Any ideas, I've tried to see if product.collections, collection.all_types with no happiness.
The reason you're getting theme-none is because your if statement checks if the collection's handle is 'clothing', 'pictures', etc. but you've set the collection to collections.all so it's never going to match any of those conditions.
What you want to do instead is check if the current product is within one of those collections. For example:
{% assign collection = collections.all %}
{% for product in collection.products %}
{% for c in product.collections %}
{% if c.handle == 'clothing' %}
{% assign theme = "red" %}
{% elsif c.handle == 'pictures' %}
{% assign theme = "green" %}
{% elsif c.handle == 'posters' %}
{% assign theme = "blue" %}
{% elsif c.handle == 'other' %}
{% assign theme = "beige" %}
{% else %}
{% assign theme = "none" %}
{% endif %}
{% endfor %}
<div class="theme-{{ theme }} overview-item">
...
</div>
{% endfor %}
First of all I'm learning Twig.
I was wondering if it is possible wit Twig to compare two different values from different arrays/lists?!
I have two list of items I call them like so:
{% if page.cart %}
{% for product in page.cart.products %}
{{ product.id }}
{% endfor %}
{% endif %}
And:
{% if products %}
{% for product in products %}
{{ product.id }}
{% endfor %}
{% endif %}
I want to compare both product.id's so I can create a new statement. Is there any way to compare both values? The idea is to check if an id is present in page.cart.products and if so then do something.
I want to create a new statement to display some info. Something like so:
{% if page.cart %}
{% for product in page.cart.products %}
{% set cartId %}{{ product.id }}{% endset %}
{% endfor %}
{% endif %}
{% if products %}
{% for product in products %}
{% set listId %}{{ product.id }}{% endset %}
{% endfor %}
{% endif %}
{% if cartId == listId %}
.... do this ....
{% endif %}
Any help greatly appreciated!
You can loop over one array and check if the id is present in the second one. If it's there, you can do something.
{# In case you want to store them, you can do so in an array #}
{% set repeatedIds = [] %}
{% for productCart in page.cart.products if page.cart %}
{% for product in products if products %}
{% if productCart.id == product.id %}
<p>This id -> {{ product.id }} is already in page.cart.products</p>
{% set repeatedIds = repeatedIds|merge([product.id]) %}
{% endif %}
{% endfor %}
{% endfor %}
{{ dump(repeatedIds) }}
It's a very basic search algorithm and the cost is quadratic. Obviously, there are more efficient ways to look for an element in an array (though more complicated to implement).
If the amount of products you have to deal with is not very big, you could use this solution. However, if you have, let's say, more than one hundred products in each array (or you feel that the algorithm is slowing down your loading time), you could do this process in the controller using more sophisticated methods and PHP and just pass the result to the template.
Hope it helps.
I'am using following code to set selectedGallery to a defaultValue. The default Value should be galleryData's first Element.
Sadly it doesn't work. selectedGallery does not exist after the snipped run through...
Thanks for help
{% if selectedGallery is not defined %}
{% for gallery in galleryData|keys|slice(0, 1) %}
{% set selectedGallery = gallery %}
//if i access galleryData here, it exists ?!
{% endfor %}
{% endif %}
later the same file:
<div id="{{idPref}}PictureBox" class="backA">
{% block pictureBox %}
{% for picture in galleryData[selectedGallery] %}
{{selectedGallery}}
{% endfor %}
{% endblock %}
Symfony says that the variable doesn't exists.
Try:
First:
{% if selectedGallery is not defined %}
{% set selectedGallery = galleryData|keys|first %}
{# ... #}

Later:
<div id="{{idPref}}PictureBox" class="backA">
{% block pictureBox %}
{% for picture in attribute(galleryData, selectedGallery) %}
{{picture}}
{% endfor %}
{% endblock %}
