I want to show the featured image of the product if it has no variants attributed to it, but if it does, I want to show the selected variant image via the product.selected_or_first_available_variant.image object.
However despite numerous attempts, on product pages with no variants I get the no image thumbnail which looks like this: http://cdn.shopify.com/s/assets/no-image-2048-5e88c1b20e087fb7bbe9a3771824e743c244f437e4f8ba93bbf7b11b53f7824c.gif
These are the three approaches I have attempted below:
{% if product.variants.price < 1 %}
{% assign featured_image = product.featured_image | img_url: 'master' %}
{% else %}
{% assign featured_image = product.selected_or_first_available_variant.image | img_url: 'master' %}
{% endif %}
{% if product.variants.price == 0 %}
{% assign featured_image = product.featured_image | img_url: 'master' %}
{% else %}
{% assign featured_image = product.selected_or_first_available_variant.image | img_url: 'master' %}
{% endif %}
{% if product.variants.price == 'null' %}
{% assign featured_image = product.featured_image | img_url: 'master' %}
{% else %}
{% assign featured_image = product.selected_or_first_available_variant.image | img_url: 'master' %}
{% endif %}
None of them work. Why? What do I need to do to get value of no variants?
ALSO: I just tried "undefined" - didn't work either.
{% if product.variants.price == 'undefined' %}...
You can simply use .
{% if product.has_only_default_variant %}
You can see it in action here: product-has_only_default_variant

I read about nunjucks set filter. I'm just not sure what would be the equivalent?
I got this piece of YAML and i want jinja2 to assign and create item.menu, if it is not previously defined.
data:
- name: bar
menu: blah
- name: foo
This is my code, the error-output ist "template error while templating string: expected token 'end of statement block'"
{% for item in data %}
{% if item.menu is not defined %}
{% set item.menu=item.name %}
{% endif %}
{% endfor %}
Any Help about what I did wrong would be much apretiated :)
Greetings, Hendrik
You're question is not clear but here is my answer. I'll make everything explicit :
{% for item in data %}
{% if item.menu is not defined %}
{{ item.name }}
{% else %}
{{ item.menu }}
{% endif %}
{% endfor %}
I'm working on custom solution for Shopify store and my problem is that I can't manage how to avoid adding ' / ' after the last matched tag in the case statement.
I've tried to use some if statements with a forloop filters with no result.
The last thing on my mind was finding the last matched tag in the loop that will help us avoiding ' / ' after the last element, but unfortunately I can't manage how to do that.
Expected result: Wool/Nylon/Viscose
Here is the part of the code that compares all tags assigned to the product with the list of tags(clothing materials) required for the output.
Considering that product has such tags as Wool, Nylon and Viscose and others, non material.
Example 1
Actual & Expected Result: WoolNylonViscose
{% for tag in product.tags %}
{% case tag %}
{% when 'Viscose' %}
Viscose
{% when 'Wool' %}
Wool
{% when 'Polyamide' %}
Polyamide
{% when 'Nylon' %}
Nylon
{% else %}
{% endcase %}
{% endfor %}
Example 2
Filter forloop.last was used to define the last element of the loop, but the problem is that material tags(Wool, Nylon, Viscose) can be in the middle of the product tag array. Considering product has 10 tags and material tags are spread among the array we will see next result.
Result: ///Wool/Nylon////Viscose//
{% for tag in product.tags %}
{% if forloop.last == true %}
{% case tag %}
{% when 'Viscose' %}
Viscose
{% when 'Wool' %}
Wool
{% when 'Nylon' %}
Nylon
{% else %}
{% endcase %}
{% else %}
{% case tag %}
{% when 'Viscose' %}
Viscose
{% when 'Wool' %}
Wool
{% when 'Nylon' %}
Nylon
{% else %}
{% endcase %}
/
{% endif %}
{% endfor %}
I would appreciate if you could please point on my mistakes and suggest me how can i achieve solution.
This should work:
{% capture tag_string %}{% endcapture %}
{% for tag in product.tags %}
{% if tag == 'Viscose' %}{% capture tag_string %}{{ tag_string }}Viscose/{% endcapture %}
{% elsif tag == 'Wool' %}{% capture tag_string %}{{ tag_string }}Wool/{% endcapture %}
{% elsif tag == 'Polyamide' %}{% capture tag_string %}{{ tag_string }}Polyamide/{% endcapture %}
{% elsif tag == 'Nylon' %}{% capture tag_string %}{{ tag_string }}Nylon/{% endcapture %}
{% endif %}
{% endfor %}
{{ tag_string | split: "" | reverse | join: "" | remove_first: "/" | split: "" | reverse }}
More on string filters: https://help.shopify.com/themes/liquid/filters/string-filters
You can try the following:-
{% for tag in product.tags %}
{% case tag %}
{% when 'Viscose' %}
{{ 'Viscose' | append: '/' }}
{% when 'Wool' %}
{{ 'Wool' | append: '/' }}
{% when 'Polyamide' %}
{{ 'Polyamide' | append: '/' }}
{% when 'Nylon' %}
{{ 'Nylon' }}
{% else %}
{% endcase %}
{% endfor %}
I want use bellow code to display custom date in my Jekyll site
{% assign m = page.date | date: "%-m" %}
{% case m %}
{% when '1' %}Januar
{% when '2' %}Februar
{% when '3' %}März
{% when '4' %}April
{% when '5' %}Mai
{% when '6' %}Juni
{% when '7' %}Juli
{% when '8' %}August
{% when '9' %}September
{% when '10' %}Oktober
{% when '11' %}November
{% when '12' %}Dezember
{% endcase %}
But I don't now where to put it (I tried in post.html but does not work)
I've made a template for this.
This template translate a date in a specific language. Here it's french but feel free to change month and day arrays.
This template can be used in an enumeration of post/page (eg: the index page) or in a post/page template.
When used in an enumeration, you need to pass the date to process
{% for post in site.posts %}
<li>
<span class="post-date">{% include custom_date_full_fr.html date = post.date %}</span>
<a class="post-link" href="{{ post.url | prepend: site.baseurl }}">{{ post.title }}</a>
</li>
{% endfor %}
Where used in a page/post template, you just have to include the template, as the page.date will already be available.
{% include custom_date_full_fr.html %}
custom_date_full_fr.html
{% if include.date %}
{% assign processed_date = include.date %}
{% else if page.date %}
{% assign processed_date = page.date %}
{% endif %}
{% comment %}-------- Test if we have a date to process --------{% endcomment %}
{% if processed_date %}
{% assign month = "janvier,février,mars,avril,mai,juin,juillet,août,septembre,octobre,novembre,décembre" | split: "," %}
{% comment %}------ Note : sunday is the first day in this array -------{% endcomment %}
{% assign day = "dimanche,lundi,mardi,mercredi,jeudi,vendredi,samedi" | split: "," %}
{% assign month_index = processed_date | date: "%m" | minus: 1 %}
{%comment%}----------------------------------------------
Here **minus: 0** is a trick to convert day_index from string to integer and then use it as an array index.
----------------------------------------------{%endcomment%}
{% assign day_index = processed_date | date: "%w" | minus: 0 %}
{%comment%}-------- Output the date ----------{%endcomment%}
{{ day[day_index] }} {{ processed_date | date: "%d" }} {{ month[month_index] }} {{ processed_date | date: "%Y" }}
{% endif %}

Liquid documentation - date filters
I'm trying to figure out how to display the total number of posts in a category (or all together). I envision something like below, but can't quite figure it out. Did I miss something from the docs?
{% for post in site.categories.CAT %}
...do some counting
{% endfor %}
posts: {% number_of_posts %}
{% for post in site.categories.CAT %}
{{ post.title }}
{% endfor %}
# all posts
{{ site.posts | size }}
# posts in one category
{{ site.categories.CAT | size }}
{% for post in site.categories.CAT %}
{% capture post_count %} {{ post_count | plus: 1 }} {% endcapture %}
{% endfor %}
{{ post_count }}
