Resolved: Laravel previous and next page into controller

Question:

I’m using this Laravel SEO package artesaos/seotools.
Is there a way for get prev and next page for pagination in controller?

function seoMetaDetail($detail)
{
    SEOMeta::setCanonical(request()->fullUrl());         
    SEOMeta::setPrev(''); <-- previous page
    SEOMeta::setNext(''); <-- next page
}

Answer:

You can get the current page from the query string.

function seoMetaDetail($detail)
{
    $current = request()->query('page');

    SEOMeta::setCanonical(request()->fullUrl());
    // If there's no current, then we're on page 1. return null. Otherwise current - 1
    SEOMeta::setPrev($current ? ($current - 1) : null);
    // If there's no current, then we're on page 1, return 2. Otherwise current + 1
    SEOMeta::setNext($current ? ($current + 1) : 2);

}

You can also use the paginator methods.

public function seoMetaDetail($detail)
{
    $paginator = YourModel::query()->....->paginate();

    SEOMeta::setCanonical(request()->fullUrl());
    SEOMeta::setPrev($paginator->previousPageUrl());
    SEOMeta::setNext($paginator->nextPageUrl());
}
