Access collection tree via id?

[stephenmeehanuk]

Hi,

I'm using products_entries_field to cherry pick entires from collection:products. collection:products is being used as a navigation.

In collection:divisions l'd like to pick a page from from collection:products and display any child pages.

I've got this so far.

{{ products_entries_field }}
    {{ nav:collection:products as="entries" id:contains="{id}"}}
        <ul> 
            {{ entries }}              
                <li><a href="{{ url }}">{{ title }}</a></li>
                    {{ if children }}              
                        {{ children }}
                            <li><a href="{{ url }}">{{ title }}</a></li>
                        {{ /children }}
                    {{ /if }}
            {{ /entries }}
        </ul>                
    {{ /nav:collection:products }}
{{ /products_entries_field }}

This will show the parent, but not the children?

Products is an ordered collection?

[stephenmeehanuk]

Yes, products_entries_field is in collection:divisions, I'm using it to associate entries from collection:products

collection:products is an ordered collection, I'm using two blueprints to create parent and child pages.

On divisions/show I can display products_entries_field like this:

{{ products_entries_field as="items"}}
    <ul>
        {{ items }}
            <li><a href="{{ url }}">{{ title }}</a></li>
        {{ /items }}
    </ul>
{{ /products_entries_field }

Some of the entires from products_entries_field have child pages.

I'm was hoping to be able to display them within that loop.

Essentially, I'm trying to do this, but this doesn't work...

{{ products_entries_field as="items"}}
    <ul>
        {{ items }}
            <li><a href="{{ url }}">{{ title }}</a>
                {{ if children }}
                    <ul>
                        {{ children }}
                        <li><a href="{{ url }}">{{ title }}</a></li>
                        {{ /children }}
                    </ul>  
                {{ /if }}
            </li>   
        {{ /items }}
    </ul>
{{ /products_entries_field }}

If the products collection has routes, the following is one way that it could be done (someone else may know a cleaner way):

<ul>
{{ products_entries_field }}
    <li>
    {{ title }}

    {{#
            Get the nav structure starting at the current product.
            Note: I chose 5 for max_depth arbitrarily
     #}}
    {{ nav:collection:products :from="url" as="entries" max_depth="5" }}
        {{#
            The start of our inner loop.
            This will only show the inner ul if there are any items.
        #}}
        {{ if entries | count > 0 }}
        <ul>
            {{# Loop through the entries like normal. #}}
            {{ entries }}
            <li>{{ title }}</li>

            {{#
                We can now do our children array (with recursion if we want).
            #}}
            {{ if children }}
                <ul>
                    {{ children }}
                        <li>
                            {{ title }}
                        
                            {{ if children }}
                                <ul>{{ *recursive children* }}</ul>
                            {{ /if }}
                        </li>
                    {{ /children }}
                </ul>
            {{ /if }}
            {{ /entries }}
        </ul>
        {{ /if }}
    {{ /nav:collection:products }}
    </li>
{{ /products_entries_field }}
</ul>

I set up a local test like so:

And the above template produces the following result:

I think in the original example, the id:contains="{id}" part of the query is being applied to all of the children, causing them to be excluded.

That's great, thanks so much for taking a look at this. It works!

I added {{ if products_entries_field }} ... {{ /if }} around the entire loop, as the page threw an error if products_entries_field didn't exist.
