{%- liquid
assign previous_product = collection.previous_product
assign next_product = collection.next_product
if previous_product or next_product
else
assign collectionList = product.collections[0].handle
assign previous_product = nil
assign next_product = nil
assign last = collections[collectionList].products_count
for p in collections[collectionList].products
if p.handle == product.handle
assign prev = forloop.index | minus: 2
assign next = forloop.index
if prev >= 0
assign previous_product = collections[collectionList].products[prev].handle
endif
if last >= next
assign next_product = collections[collectionList].products[next].handle

Hi @minhsien,

I have checked and the products are not working well. Can you send me the product link that works well? I will check it.

You can also refer to my previous tutorial: https://community.shopify.com/c/shopify-design/add-previous-and-next-buttons-to-dawn-theme/td-p/1461...

Hope it helps!

Thank you for the reply. my is theme dawn 4.0 therefore i could not find

product-card.liquid file, find 'card-information__text h5

as mentioned in your post. And i am sorry that i have deleted the old
liquid, and i can't find the original source right now. Perhaps i could
provide my shopify line for you to check?

Hi @minhsien,

Please find 'card_product.url', change 

card_product.url

=>

card_product.url | within: collection | default: '#'

Hope it helps!

https://mzakkaya.com/products/summer-childrens-short-sleeved-boy-t-shirt-cotton-bottoming-top

https://mzakkaya.com/products/t-shirt-slub-cotton-casual-top

Please check above. These products are in the same collection, howewver some products did not show the previous and next link as well.  And i might need to move the link to the right side of the page.

Hi @minhsien,

The next and previous button is only displayed when you visit the collection page and have a product link: https://mzakkaya.com/collections/trendy/products/kids-sunscreen-lace-lace-breathable-bucket-hat

So you need to change the product link in step 1 as per my previous instructions.

Hope it is clear to you.

Hi @minhsien put this line in your collection page 

{% assign url = card_product.url | within: collection %}

and your collection link should look something like this: - 

 <a href="{{ url }}" class="full-unstyled-link">

                {{ item.title | escape }}

              </a>

i hope this helps
