How to adjust slider window on custom Content Query pagination?

[sarahessex]

Hi, I have a custom Content Query that I am using the ->paginate() method on..

    $paginator =  Entry::query()
            // ...custom query here...
            ->paginate(15);

I'm then generating the pagination data (which I copied from Statamic\Tags\Concerns\OutputsItems->getPaginationData())

    $pagination = [
                'total_items'    => $paginator->total(),
                'items_per_page' => $paginator->perPage(),
                'total_pages'    => $paginator->lastPage(),
                'current_page'   => $paginator->currentPage(),
                'prev_page'      => $paginator->previousPageUrl(),
                'next_page'      => $paginator->nextPageUrl(),
                'auto_links'     => $paginator->render('pagination::default'),
                'links'          => $paginator->renderArray()
            ];

    $view->with( 'pagination', $pagination);

And in my Antlers template...

{{ partial:pagination :paginate='pagination'}}

This gives me the paginate so that I can use it in the same way as in your Collection Example...

    {{ paginate }}
    <ul class="pagination">
        {{ if prev_page }}
            <li><a href="{{ prev_page }}">&laquo;</a></li>
        {{ else }}
            <li class="disabled"><span>&laquo;</span></li>
        {{ /if }}
 
        {{ links:segments }}
 
            {{ first }}
                {{ if page == current_page }}
                    <li class="active"><span>{{ page }}</span></li>
                {{ else }}
                    <li><a href="{{ url }}">{{ page }}</a></li>
                {{ /if }}
            {{ /first }}
 
            {{ if slider }}
                <li class="disabled"><span>...</span></li>
            {{ /if }}
 
            {{ slider }}
                {{ if page == current_page }}
                    <li class="active"><span>{{ page }}</span></li>
                {{ else }}
                    <li><a href="{{ url }}">{{ page }}</a></li>
                {{ /if }}
            {{ /slider }}
 
            {{ if slider || (!slider && last) }}
                <li class="disabled"><span>...</span></li>
            {{ /if }}
 
            {{ last }}
                {{ if page == current_page }}
                    <li class="active"><span>{{ page }}</span></li>
                {{ else }}
                    <li><a href="{{ url }}">{{ page }}</a></li>
                {{ /if }}
            {{ /last }}
 
        {{ /links:segments }}
 
        {{ if next_page }}
            <li><a href="{{ next_page }}">&raquo;</a></li>
        {{ else }}
            <li class="disabled"><span>&raquo;</span></li>
        {{ /if }}
    </ul>
    {{ /paginate }}

All working fine, I can either do {{ auto_links }} or include the above partial for custom pagination.

My question is that the default slider window is 10, is there any way I can adjust it down? I found this discussion #5001 but I think that on_each_side usage is for the core collection pagination only? Can I insert it somewhere as a parameter to have the same effect or would it be a case of having to write something custom?

I've tried setting $paginator->onEachSide = 3 before calling $paginator->renderArray() on the links part of my $pagination array, but it hasn't had an effect.

Thanks.

Instead of doing $paginator->onEachSide = 3, you should use the method:

$paginator->onEachSide(3);

            $paginator = $query->paginate($max);

            $paginator->onEachSide(3);

            $pagination = [
                'total_items'    => $paginator->total(),
                'items_per_page' => $paginator->perPage(),
                'total_pages'    => $paginator->lastPage(),
                'current_page'   => $paginator->currentPage(),
                'prev_page'      => $paginator->previousPageUrl(),
                'next_page'      => $paginator->nextPageUrl(),
                'auto_links'     => $paginator->render('pagination::default'),
                'links'          => $paginator->renderArray(),
            ];

Is still getting me 10 on each side. (When I'm using {{ links:segments }} ... {{ /links:segments }} in the partial example )

Honestly the pagination window thing is a bit of a black box to me.

If you go to page 11, what does it look like?

[sarahessex]

I know the feeling..!

Ok, I think I've realised the onEachSide parameter is not quite what I thought it was... seems to be 'on each side of the current page number' rather than the size of the first/last link ranges (though, it does adjust that too, just not in a way I can work out)...

When I do $paginator->onEachSide(1);...

When on page 1:

1 2 3 4 5 6 ... 28 29

When on page 11:

1 2 ... 10 11 12 ... 28 29 // 1 link on each side of current

When I do $paginator->onEachSide(3);...

When on page 1:

1 2 3 4 5 6 7 8 9 10 ... 28 29

When on page 11:

1 2 ... 8 9 10 11 12 13 14 ... 28 29 // 3 links on each side of current

I don't really get how it's working out how many to show before the separator when on page 1, but putting it right down to $paginator->onEachSide(1) kind of gets me what I needed so I can work with that! Thanks.
