Additional Insights on Pagination and Query String Parameters

Keeping Query Parameters Persistent

When you paginate your results, all required parameters such as page and offset will automatically append to the pagination function. However, if you have specific filtering parameters in the query string that you want to maintain across requests (when users click on the next page or previous page), you should provide an additional method:

This ensures that any filtering parameters returned in $_GET are kept intact while you navigate through the pages.

Conclusion

In summary, addressing the issue with withQueryString() in a Laravel pagination setup requires a simple reordering of method calls. Remember to apply withQueryString() before you paginate your results. Keeping your query parameters persistent across pagination requests enhances user experience and ensures that your application functions smoothly.

By following the suggestions outlined above, you should no longer encounter the error regarding the withQueryString method. Happy coding with Laravel!
