Is it possible to assign a variable and use that variable in the for loop statement?
I'm trying to place a collection of products in a blog without having to create a new for loop for each article that needs a collection.
What I've done is using the article's tags and splitting just before the collection handle so I can inject it in the for loop, but it's not quite working dynamically yet...
Here's what I've done.. I added in the article tags
collection_some-page-handle
Then in the article.liquid
{% for tag in article.tags %}
{% assign tagMap = tag | split: '_' %}
{% if tagMap.first == 'collection' %}
{% assign collectionName = tagMap.last %}
{% endif %}
{% endfor %}
{{collectionName}} <!-- this shows the handle of the collection -->
{% for product in collections.collectionName.products limit: 8%}
<div class="productWrap">
<img src="{{ product.featured_image | product_img_url: 'medium' }}" alt="">
<p class="product_title" style="border-top:1px solid #efefef;">{{ product.title | split: ' - ' | first }}</p>
</div>
{%endfor%}
Now if i try to put the variable in the for loop it doesnt work, but of course if i put the actual handle it works. Is there a way to do it dynamically?
Instead of using collections.collectionName use collections[collectionName].
This should fix your issue if your variable has the proper handle indeed.
To clarify when you use collections.collectionName you say - "Get me a collection that have handle collectionName`.
When you use collections[collectionName] you say - "Get me a collection using the variable collectionName as a handle."

I have create many collections like All Products, New Releases, T-Shirts, Pants etc. And I have two categories of products like Men's and Women's. Some collections specifically for Men's and some collections specifically for Women's. I create two tags Men's and Women's. I create menu by collections query by tags. My my products collection url is like this:
/collections/all-products/mens
/collections/all-products/womens
/collections/new-releases/mens
/collections/new-releases/womens
/collections/bras/womens
I want to show some text and menu list when collection.url show /mens or /womens.
{% if collection.url contains mens %}
do something
{% endif %
Above condition not working. I know why not working because {{ collection.url }} provide /collections/all-products. {{ page.url }} will not work for collection object. I haven't find any suggestion or liquid code reference where show men's or women's products in collections page it will show specific text.
If use in loop it will work.
{% for product in collection.products %}
{% for tag in product.tags %}
{% if tag contains 'mens' %}
<h3>Mens Products</h3>
{% endif %}
{% endfor %}
{% endfor %}
Above code will not work for me because it's inside loop. I need to show outside of loop. I don't understand how to achieve it. here is the reference site. Below have image how I want.
Need help!
You have access to the current_tags, refer to docs: https://shopify.dev/docs/themes/liquid/reference/objects/current-tags
This will return an array of all the tags you are viewing at the moment (in case you are viewing more than one tag).
So your check will be:
{% if current_tags contains 'mens' %}
do something
{% endif %}
That's pretty much the just of it.
I really like how the menu is coming along! Here are some ideas you could consider for your category specific menu, if you've not gotten where you want yet.
For your url strategy, what you're looking for is handle. Handles are specific to liquid. https://shopify.dev/docs/themes/liquid/reference/basics/handle
You could make a custom collection template if those 2 categories need to be fairly different: https://shopify.dev/tutorials/customize-theme-create-alternate-templates. If you do that, then you can use template_prefix from the collection object.
Assign a variable outside your loop and then set it inside the loop like:
{% assign is_mens = false %}
{% for tag in product.tags %}
{% if tag contains 'mens' %}
{% assign is_mens = true %}
{% endif %}
{% endfor %}
then {% if is_mens %} or {% unless is_mens %} for your dynamic content, or a case statement to define content specific to categories in your menu.
Hope this helps!
I'm trying to set up a page which displays a list of collections, like the general 'list-collections.liquid', but only display collections that contain products with a certain product tag.
I've tried doing it like this:
{% assign var = 'test' %}
{% assign tagtrue = false %}
{% for collection in collections %}
{% unless collection.handle == 'frontpage' %}
{% for product in collection.products %}
{% for tag in product.tags %}
{% if tag contains var %}
{% assign tagtrue = true %}
{% endif %}
{% endfor %}
{% endfor %}
{% if tagtrue == true %}
<a href="{{ collection.url }}" title="{{ 'collections.general.link_title' | t: title: title }}">
{% if collection.image != blank %}
{{ collection | img_url: '480x480' | img_tag: collection.title }}
{% elsif collection.products.first != blank %}
{{ collection.products.first | img_url: '480x480' | img_tag: collection.title }}
{% else %}
{% capture current %}{% cycle 1, 2, 3, 4, 5, 6 %}{% endcapture %}
{{ 'collection-' | append: current | placeholder_svg_tag: 'placeholder-svg placeholder-svg--small' }}
{% endif %}
</a>
<p>
{{ collection.title }}
</p>
{% endif %}
{% endunless %}
{% endfor %}
But when I go to the collection list page this still returns all collections. Any ideas how to do this?
If you look at the documentation, you'll find that a product has a special method on it labelled collections. In other words, that gives you a list of all the collections the product belongs to.
So now on to your question. You ask how you can display a list of collections, but only the ones that contain products with a specific tag. OK... fair enough. You will blow speed out the window, but a simple algorithm might be:
create a collection of products with tag foomanchu
iterate the products in that collection, and use the product.collections
for each collection listed, add it to a list if it has not already been added
Once done that loop, you have the answer. A list of collections for products with a specific tag.
Good luck with performance on that, and remember to keep it simple. That looping is fast for a small shop with limited inventory, but if you have many thousands of skus with a tag spread out across many collections, you'll be challenged for instant rendering.
You can get a speed improvement over David Lazar's answer by using Shopify's map filter.
As with his answer, step 1 is to create a collection with the rule "Product contains tag" and enter the tag that you are using.
Now assuming that you have that collection object in a Liquid variable named collection, you would get the handles of all the collections through a simple map command, followed by a uniq command to strip out all the duplicates:
{% assign all_collection_handles = collection.products | map: 'collections' | map: 'handle | uniq %}
The map filter gets very specific information from the wad of objects, so it's quite a bit faster than iterating through a lot of big objects with a slew of fields you don't care about.
(Note that uniq only works on strings, numbers, or other simple data types, which is why we map all the way to the collections' handles)
Now you can iterate through all_collection_handles to do what you need to do:
{% for handle in all_collection_handles %}
{% assign collection = collections[handle] %}
<!-- Cool stuff here -->
{% endfor %}
Since you should have a much shorter list of collections than you do of products, this should be reasonably performant. Be aware as always that the more heavy-lifting that you're doing in the Liquid code the more likely you'll get page-load delays, so keeping your loops short and using focused filters such as map whenever possible will help keep things running as fast as possible.
Note: If your page starts to suffer from extreme page-load lag, you may want to skip doing this as part of the page-load and just leave a placeholder element, then use Javascript to fetch the information you need and create the display you want.
on shopify, i want a line of code of code from theme.liquid to show only on collection pages regardless the template used (i have a few custom collection templates). how do i write the code to do this?
currently i'm using.
{% if template == 'collection.home' %}
<div class="filter_btn">
loremipsum
</div>
{% endif %}
{% if template == 'collection.featured' %}
<div class="filter_btn">
loremipsum
</div>
{% endif %}
similar duplicate of code above for other collection template
i will be adding new collections with new custom templates in the future, but that means i have to duplicate more of the same to cover new collection templates..
how can i have a line of code that covers all collection templates / collection pages
Use the contains operator instead:
{% if template contains 'collection' %}
I am likely a collection template
{% endif %}
See more about contains here:

I'm trying to retrieve all Shopify collections for our store which have products matching tag dog.
{% for collection in collections %}
{% assign gato = 'false' %}
{% assign perro = 'false' %}
{% for tag in collection.tags %}
{% if tag == 'Cat' %}
{% assign cat = 'true' %}
{% elsif tag == 'Dog' %}
{% assign dog = 'true' %}
{% endif %}
{% endfor %}
{% if dog == 'true' and cat == 'false' %}
<li>{{ collection.title | link_to: collection.url }}</li>
{% endif %}
{% endfor %}
I successfully get this list when I'm at homepage (telepienso.com). (See footer screenshot: A). I have the same exact code in collection.liquid and I get some of the collections but NOT all of them. (telepienso.com/collections/all). (See list on the right screenshot: B). Is there any restriction inside collection.liquid which can affect?

This was the cause of the problem. The collections variable was being paginated.
By moving the code in the question outside of the paginate liquid tag, all collections are displayed in the sidebar (the same as the footer).
EDIT: The above link is broken because the question was deleted due to low traffic. I've copied the content from the question below for reference.
Shopify - issue accessing the collections global variable inside paginate
I would like to be able to access the collections global variable from within a paginated group of products, but the collections variable is also paginated if it is accessed within a paginate liquid tag.
For example (in collection.liquid):
{% for collection in collections %}
{{ collection.title }}
{% endfor %}
<br />
{% paginate collection.products by 4 %}
{% for collection in collections %}
{{ collection.title }}
{% endfor %}
...
{% endpaginate %}
Output:
All Collection1 Collection2 Collection3 Collection4 Collection5 Collection6 Frontpage
All Collection1 Collection2 Collection3
The for loop before the paginate tag lists all collections as you would expect, but doing the same thing within the paginate tag causes collections to be paginated as well as the products I am actually wanting to paginate.
Is there a way to access the collections global variable within a paginated group of products without it also being affected by the pagination?
Why would I want to do this? It was causing this problem, and was not immediately obvious because the code using the collections variable was in a separate snippet to the code with the pagination.
EDIT 2: I can no longer reproduce this issue, it appears to have been fixed.
This seems like an easy one, but after researching and banging around for a couple of hours I still can't figure it out. My goal is to insert a non-product HTML block in the Shopify collection grid, like the "Enjoy Free Ground Shipping" block in row 1, col 3 here:
http://www.katespade.com/designer-handbags/handbags,default,sc.html
My collection grid is set to 3 columns by 4 rows per page, and I'm looking to replace the block at row 2, column 1 for all collection pages with 3 or more products.
The Liquid loop I need to modify is:
<ul class="product-grid clearfix">
{% for product in collection.products %}
<li{% cycle '', '', ' class="last-in-row"' %}>
{% include 'product-grid-item' %}
</li>
{% endfor %}
</ul>
Does anyone have any insights?
Welcome to Stack Overflow! :-)
First, let me pseudocode this to make sure we're on the same page, and that I've got the logic right.
for each product in collection
{
is this the 4th iteration of the loop?
(in other words, is it the first item in the second row)
{
Add an <li> for the custom non-product block.
}
Add an <li> for the standard product block
}
If that logic fits what you're looking for, here's the real thing in Liquid.
<ul class="product-grid clearfix">
{% for product in collection.products %}
{% if forloop.index == 4 %}
<li{% cycle '', '', ' class="last-in-row"' %}>
{% include 'your-custom-block-element' %}
</li>
{% endif %}
<li{% cycle '', '', ' class="last-in-row"' %}>
{% include 'product-grid-item' %}
</li>
{% endfor %}
</ul>
You may have noticed that Shopify deals with 1-based indices by default. That's why we're looking for forloop.index == 4. In almost every other language we'd be dealing with a zero-based index and checking if forloop.index == 3.
If this convention bugs you, you can always use forloop.index0 to check for the loop's index with a base of zero instead. ;-)
Please let me know if this does the trick for you. Good luck!
