Laravel Pagination links not including other GET parameters

Title: Addressing Laravel Pagination Issues with GET Parameters in URLs A common issue faced when working with pagination in Laravel is that when there are existing GET parameters present in the URL, such as gender=female&body=hot, the generated pagination links only contain the page parameter and disregard other vital data. In this comprehensive blog post, we will explore ways to maintain all relevant GET parameters in our paginated links without the use of if/else statements or messy code. To begin with, let's understand why Laravel's pagination links seem to ignore other GET parameters. The default pagination generation method works on the assumption that we want only a single parameter - "page" - in our URL for paginated results. This is to ensure that any user can visit the first page of the result, and then incrementally navigate to subsequent pages if the total records are extensive. However, it does not consider other data users might need along with their search query or filtering options. Now let's discuss some approaches that enable us to include other GET parameters in Laravel pagination links: 1. **Using the append() Function** Laravel provides a handy append() function which can be used to add additional parameters to our URL while generating pagination links. Let's assume we want to maintain both gender and body parameters in the paginated link. We could do so by incorporating them with the append() function in the following manner:

{{ $users->link('page', null, $prev_page_url, true) }}

{{ $users->append(['gender' => 'female'], 'body' => 'hot')->links() }}

In this example, we first append the gender parameter with a value of "female" and then add the body parameter with a value of "hot". By wrapping these appended parameters in another links() call, we generate pagination links that retain all the original query string parameters and include the current page as well. 2. **Building Custom Pagination Links** In cases where you don't know how many GET parameters there are or if they change dynamically, building custom pagination links becomes a better option. This can be done by manually creating a URL with the desired parameters and then using Laravel's URL helper function to generate links for that URL:

$url = 'http://site.example/users?' . http_build_query(request()->except('page'));

Here, we use the request() helper function to extract all GET parameters except the current page parameter. The URL is then constructed by concatenating it with the original URL and using the http_build_query() function to reassemble the newly built query string. Finally, our pagination links will look like:

{{ $users->links($url) }}

3. **Using Query Strings with Laravel** Another approach is to use query strings in conjunction with the existing paginated URLs instead of generating new ones. This method works best when you don't want your users to notice any difference in their search results, and a seamless transition is desired. To do so, you can append the current page parameter as a new GET parameter to our URL:

{{ $users->link('page', null, true) }}

In this example, we use the link() method with an additional boolean argument set to true, indicating that both the current page and any existing query parameters should be included in the generated URL. This results in a paginated link that considers all the existing GET parameters alongside the page parameter. By following one of these methods, you can ensure that your Laravel pagination links include all relevant GET parameters without compromising on functionality or usability. As always, it's essential to keep your code clean and maintainable for future maintenance and updates.
