Question

I’m surprised I haven’t run into this before, or at least I forgot how I got it working.

I have a standard EE relationship field. In this case, I have a “Products” channel, and each product belongs to an entry in the “Designers” channel.

I quite obviously want a page to list all products for a single designer. My first attempt looked like this:

{exp:channel:entries channel="designers" url_title="{segment_3}" limit="1"}

    {reverse_related_entries channel="products" limit="15"}
        {snippet_product_grid}
        {snippet_paginate}
    {/reverse_related_entries}

{/exp:channel:entries}

According to anecdotal evidence in the EE documentation, you can’t paginate reverse related entries. So what’s the solution? Is there a way to easily grab all the product entry IDs, given the url_title of a designer? Or do I have to resort to using SQL?

Is there any way I could solve this using the Stash add-on?

What janvl said with playa. Using stash, you want to use the dev branch to which Mark Croxton has added a pagination feature for {exp:stash:get_list}

https://github.com/croxton/Stash/tree/dev#expstashget_list-tag-pair

Haven’t tested this code on a local sandbox but the code below should get you started

{exp:channel:entries channel="designers" url_title="{segment_3}" limit="1"}
    {exp:stash:set_list name="related_products" parse_tags="yes"}
        {reverse_related_entries channel="products"}
            {stash:st_item_title}{title}{/stash:st_item_title}
        {/reverse_related_entries}
    {/exp:stash:set_list}
{/exp:channel:entries}


{exp:stash:get_list name="related_products" parse_tags="yes" parse_conditionals="yes" prefix="my_prefix" paginate="bottom"}

    {if my_prefix:count == 1}<ul>{/if}
        <li>{st_item_title}</li>
    {if my_prefix:count == my_prefix:total_results}</ul>{/if}

    {if my_prefix:no_results}
        <p>No related products</a></p>
    {/if}

    {my_prefix:paginate}
        {pagination_links}
            <ul>
                {first_page}
                        <li><a href="{pagination_url}" class="page-first">First Page</a></li>
                {/first_page}

                {previous_page}
                        <li><a href="{pagination_url}" class="page-previous">Previous Page</a></li>
                {/previous_page}

                {page}
                        <li><a href="{pagination_url}" class="page-{pagination_page_number} {if current_page}active{/if}">{pagination_page_number}</a></li>
                {/page}

                {next_page}
                        <li><a href="{pagination_url}" class="page-next">Next Page</a></li>
                {/next_page}

                {last_page}
                        <li><a href="{pagination_url}" class="page-last">Last Page</a></li>
                {/last_page}
            </ul>
        {/pagination_links}
    {/my_prefix:paginate}

{/exp:stash:get_list}
