Livewire 3 Pagination Displays Incomplete Data and Missing Buttons on Certain Pages

I'm experiencing an issue with Livewire 3 pagination when combining union queries. When I navigate to the 2nd page, everything displays correctly. However, going to either the 3rd page or returning to the 1st page shows only 1 to 4 records and the pagination buttons disappear.

Below is my Livewire ProfileFeed.php component:

PHP
<?php
namespace App\Livewire;

use App\Models\LawPost;
use App\Models\QBankPost;
use Livewire\Component;
use Livewire\WithPagination;
use Illuminate\Support\Facades\DB;

class ProfileFeed extends Component
{
    use WithPagination;

    protected $paginationTheme = 'tailwind';

    public function getPostsProperty()
    {
        $qbankQuery = QBankPost::query()
            ->where('is_published', true)
            ->select('id', 'question as title', 'slug', 'answer as content', 'published_at', 'seo_image', 'label');

        $lawPosts = LawPost::query()
            ->where('is_published', true)
            ->select('id', 'title', 'slug', 'content', 'published_at', 'seo_image', 'label');

        $combinedQuery = $lawPosts->unionAll($qbankQuery);

        return DB::table(DB::raw("({$combinedQuery->toSql()}) as combined"))
            ->mergeBindings($combinedQuery->getQuery())
            ->orderBy('published_at', 'desc')
            ->paginate(10);
    }

    public function render()
    {
        return view('livewire.profile-feed', [
            'posts' => $this->posts,
        ]);
    }
}

And here is the profile-feed.blade.php view:

BLADE
<div>
    @forelse ($posts as $post)
        <div wire:key="{{ $post->id }}">
            <article class="group grid rounded-sm grid-cols-1 md:grid-cols-8 overflow-hidden border border-neutral-300 bg-neutral-50 text-neutral-600 dark:border-neutral-700 dark:bg-neutral-900 dark:text-neutral-300 mb-5">
                <div class="flex items-center justify-center overflow-hidden mx-5 my-5">
                    <img src="{{ $post->seo_image ? asset($post->seo_image) : asset('images/' . $post->label . '/' . $post->slug . '.jpg') }}" class="h-52 md:h-full w-full object-cover transition duration-700 ease-out group-hover:scale-105" alt="{{  $post->title }}" />
                </div>
                <div class="flex flex-col justify-center p-6 col-span-5">

                    <a href="{{ route("{$post->label}.show", $post->slug) }}">
                        <h3 class="text-balance text-xl font-bold text-neutral-900 lg:text-2xl dark:text-white">{{ $post->title }}</h3>
                        <p class="my-4 max-w-lg text-pretty text-sm">
                            {!! Str::limit($post->content, 150) !!}
                        </p>
                        <span class="w-fit font-medium text-black underline-offset-2 hover:underline focus:underline focus:outline-hidden dark:text-white">
                            Published on: {{ \Carbon\Carbon::parse($post->published_at)->diffForHumans() }}
                        </span>
                    </a>
                </div>
            </article>
        </div>
            @empty
             No Post Found
        @endforelse

    <!-- Livewire pagination links -->
    <div class="mt-6">
        {{ $posts->links() }}
    </div>
</div>

Finally, my profile.blade.php view includes the Livewire component as follows:

BLADE
<livewire:profile-post-tab />

I would like to have the pagination display the correct number of items and show all the pagination buttons consistently across all pages. Any suggestions or fixes for this behavior would be appreciated.

This behavior is usually caused by the way Laravel’s paginator computes the total number of records when you’re using a union (especially wrapped inside a raw subquery). In other words, the count query that Laravel performs behind the scenes may not be returning the “true” total for your union query. That’s why on some pages you see “fewer” items and no pagination links.

Below are a few approaches to resolve the issue:

1. Use Simple Pagination

Since simplePaginate() does not perform an extra count query (it only checks for a “has more” condition), you can change your call from paginate(10) to simplePaginate(10):

PHP
return DB::table(DB::raw("({$combinedQuery->toSql()}) as combined"))
    ->mergeBindings($combinedQuery->getQuery())
    ->orderBy('published_at', 'desc')
    ->simplePaginate(10);

This will remove the issue with total count, although note that you lose the total page count and “jump-to-page” links.

2. Manually Build a Length-Aware Paginator

If you need full pagination features (with proper total count) you can manually compute the total count and build the paginator yourself. For example:

PHP
use Illuminate\Pagination\LengthAwarePaginator;
use Illuminate\Pagination\Paginator;

public function getPostsProperty()
{
    // Build your union query as before
    $qbankQuery = QBankPost::query()
        ->where('is_published', true)
        ->select('id', 'question as title', 'slug', 'answer as content', 'published_at', 'seo_image', 'label');

    $lawPosts = LawPost::query()
        ->where('is_published', true)
        ->select('id', 'title', 'slug', 'content', 'published_at', 'seo_image', 'label');

    $combinedQuery = $lawPosts->unionAll($qbankQuery);

    // Raw SQL and bindings
    $rawSql = "({$combinedQuery->toSql()}) as combined";

    $baseQuery = DB::table(DB::raw($rawSql))
        ->mergeBindings($combinedQuery->getQuery())
        ->orderBy('published_at', 'desc');

    // Manually get the total count
    $total = DB::table(DB::raw("({$combinedQuery->toSql()}) as sub"))
        ->mergeBindings($combinedQuery->getQuery())
        ->count();

    $perPage = 10;
    $currentPage = Paginator::resolveCurrentPage() ?: 1;
    $results = $baseQuery->forPage($currentPage, $perPage)->get();

    return new LengthAwarePaginator(
        $results,
        $total,
        $perPage,
        $currentPage,
        ['path' => request()->url(), 'query' => request()->query()]
    );
}

This approach gives you full control over the total count and the current page.

3. Consider Avoiding the Raw Union Query

If possible, avoid placing the union inside a raw expression. For example, if you can combine the queries in PHP (or use a direct raw query) and then manually paginate the merged collection, that might simplify things. Often using a collection’s paginate method (or a third-party package) can help when dealing with union data.

Summary

The root cause is that the union query confuses the standard count query that paginate() uses. Switching to simplePaginate() or manually constructing the LengthAwarePaginator are typical fixes. Choose the approach that best suits your application’s needs.

Let me know if you have further questions or need more details on any of the approaches!
