I'm trying to loop through categories that have been added to collection posts. For the default 'posts' section it's as easy as:
{% for category in site.categories %}
{{ category }}
{% endfor %}
But I can't seem to get this working for my collection. I thought it would be something along the lines of:
{% for category in my_collection.categories %}
{{ category }}
{% endfor %}
But that doesn't seem to work. Any help would be appreciated.
for anyone needing the answer to this...I've managed to solve this by adding all unique 'my_collection' categories to an array then looping through that. Here's the code:
<!-- create categories array-->
{% assign categories_array = "" | split:"|" %}
<!--Add each unique 'my_collection' category to the array-->
{% for post in site.my_collection %}
{% for category in post.categories %}
{% assign categories_array = categories_array | push: category | uniq %}
{% endfor %}
{% endfor %}
<!--Output the categories-->
{% for category in categories_array %}
{{ category }}
{% endfor %}
you can grab the name of each category like so:
{% for category in site.categories %}
{{ category | first | strip_html }}
{% endfor %}
You first have to declare the collection
{%a assign col = site.COLLECTIONNAME %}
Then you can loop inside the collection
{% for cat in col %}
{{ col.name }}
{% endfor %}

I am trying to display a list of all articles using liquid markup. I've got this code which displays them properly, however I want to be able to sort by the modified date descending (most recent article on top). How can this be accomplished?
I was thinking that perhaps I need to create a new array with all articles in it and then sort that, but I am not sure how to do that. Also note that I want to sort ALL of my articles by date, not just within each folder.
{% for category in portal.solution_categories %}
{% if category.folders_count > 0 %}
{% for folder in category.folders %}
{% for article in folder.articles %}
{{ article.title }} - {{ article.modified_on | short_day_with_time }} <br>
{% endfor %}
{% endfor %}
{% endif %}
{% endfor %}
Thanks!
You can use a variable to sort the list of articles and then iterate that variable.
{% for category in portal.solution_categories %}
{% if category.folders_count > 0 %}
{% for folder in category.folders %}
{% assign sorted = (folder.articles | sort:date) %}
{% for article in sorted %}
{{ article.title }} - {{ article.modified_on | short_day_with_time }} <br>
{% endfor %}
{% endfor %}
{% endif %}
{% endfor %}
I am trying to output a list of post titles with the 5 latest posts in ALL categories BUT one. It works fine with the filtering, unfortunately it takes the posts that are being excluded in consideration for the limit. Is there any easy way to not count the excluded posts?
{% for post in site.posts limit: 5 %}
{% if post.category == "news" %}
//Do nothing
{% else if %}
{{ post.title }}
{% endif %}
{% endfor %}
To limit filtered posts you need to filter them first.
We create an array of posts that do not include the news category:
{% assign no_news = "" | split: "" %}
{% for post in site.posts %}
{% unless post.categories contains 'news' %}
{% assign no_news = no_news | push: post %}
{% endunless %}
{% endfor %}
Now we traverse this new array limiting iterations by 5:
{% for post in no_news limit: 5 %}
{{ post.title }} - {{post.categories}}
{% endfor %}
It will output 5 posts not containing the news category.
You should be able to assign the posts first, then call them:
{% assign relevant = site.posts | except:"category","news" %}
{% for posts in relevant limit:5 %}
{{ post.title }}
{% endfor %}

I am attempting to rebuild a sidebar widget which shows my categories used in Jekyll. It works fine as it is now. I want to change the liquid templating to exclude one specific category link from being shown in this widget.
{% assign cat_list = site.categories %}
{% if cat_list.first[0] == null %}
{% for category in cat_list %}
<li>{{ category }} <span class="cat-count">{{ cat_list[category].size }}</span></li>
{% endfor %}
{% else %}
{% for category in cat_list %}
<li>{{ category[0] }} <span class="cat-count">{{ category[1].size }}</span></li>
{% endfor %}
{% endif %}
{% assign cat_list = nil %}
I think what I want is something like
{% for category in cat_list **UNLESS category = 'CATEGORY'** %}
But that did not work. I'm kinda stuck, is this possible?
Thank You.
Not displayed categories array :
{% assign noDisplay = "one,two,three" | split: "," %} => ["one", "two", "three"]
The test :
{% unless noDisplay contains category[0] %}
{{ category[0] }}...
{% endunless %}
Thank you, #David Jacquel
{% assign noDisplay = "CATEGORY" | split: "," %}
{% assign cat_list = site.categories %}
{% if cat_list.first[0] == null %}
{% for category in cat_list %}
<li>{{ category }} <span class="cat-count">{{ cat_list[category].size }}</span></li>
{% endfor %}
{% else %}
{% for category in cat_list %}
{% unless noDisplay contains category[0] %}
<li>{{ category[0] }} <span class="cat-count">{{ category[1].size }}</span></li>
{% endunless %}
{% endfor %}
{% endif %}
{% assign cat_list = nil %}
I want to loop through posts on a site except ones with the category unlisted. I'm able to do this by nesting an if statement inside the for loop, but this breaks down when I want to also specify a limit – the loop will run for 5 times only regardless of whether the post passes the check.
{% for post in site.posts limit: 5 %}
{% unless post.categories contains 'unlisted' %}
<!-- display post -->
{% endunless %}
{% endfor %}
I need to pass an already filtered list to the for loop, but I'm unable to do this mainly because I can't find a way to combine the where filter with contains and negation:
{% for post in site.posts | WHERE CATEGORIES NOT CONTAINS 'UNLISTED' | limit: 5 %}
<!-- display post -->
{% endfor %}
You can use a counter :
<ul>
{% assign postCounter = 0 %}
{% assign maxPost = 5 %}
{% for post in site.posts %}
{% unless post.categories contains 'unlisted' %}
<li>{{ post.title }}</li>
{% assign postCounter = postCounter | plus: 1 %}
{% if postCounter >= maxPost %}
{% break %}
{% endif %}
{% endunless %}
{% endfor %}
</ul>
I want to display keywords and description automatically according to the category of the current post. I've used the following code, but it doesn't worked.
{% if page.categories = "category" %}
{% else %}
{% endif %}
But while using {% page.categories %} it is echoing out the category name correctly. Here are my two doubts:
How can I compare the current post's category?
Are {{ }} and {% %} are same here?
It should look like the following:
{% if page.categories == 'some-name' %}
Hei I am in some-name category
{% else %}
No I am not in some-name category
{% endif %}
2.
No, {{ }} and {% %} are not the same. {{ }} is used for echoing stuff, while {% %} is used for logic expressions and arguments.
