As a Laravel developer, you'll often find yourself working on search functions that include date filters. A common scenario is to filter results based on a date range. However, ensuring that your end date includes the entire day can be a bit tricky. Let's break down the process and make sure your filters work perfectly.

Understanding the Problem

When we filter results by dates, it's easy to assume that specifying a start and end date will include all records within those dates. But there's a catch. Databases often store dates with time components, so if you don't handle this correctly, you might miss some records. For example, filtering from 01/06/2024 to 12/06/2024 might not include records on 12/06/2024 after 00:00:00.

The Goal

We want to make sure that our date range filters include all records from the start date's beginning 00:00:00 to the end date's end 23:59:59. This way, we won't miss any records that fall on the end date.

Step-by-Step Solution

Parsing and Formatting Dates

First, we need to convert the dates from the request into a format that our database understands. Laravel's Carbon library makes this easy. We'll parse the dates from the dd/mm/yyyy format and convert them to the yyyy-mm-dd format.

Note:

This conversion is necessary only when the date format from the client side is different from the format stored in the database. In our case, the client sends the date as dd/mm/yyyy, but the database stores it as yyyy-mm-dd.

Setting the Time Range

To ensure we include the entire end date, we'll set the start date to the beginning of the day and the end date to the end of the day using Carbon's startOfDay() and endOfDay() methods.

Applying the Date Filter

Finally, we'll apply this date range filter to our query.

Implementation in Code

Here's how you can implement this in your Laravel controller:

public function ticketsSearch(Request $request)
{
    $query = PaymentTransaction::query();


    // Adding date filter
    if ($request->has('date_filter_start') && $request->has('date_filter_end')) {
        $start_date = Carbon::createFromFormat('d/m/Y', $request->input('date_filter_start'))->startOfDay()->format('Y-m-d H:i:s');
        $end_date = Carbon::createFromFormat('d/m/Y', $request->input('date_filter_end'))->endOfDay()->format('Y-m-d H:i:s');


        $query->whereBetween('purchase_date', [$start_date, $end_date]);
    }


    $resultsPerPage = $request->input('results_per_page', 10);


    $tickets = $query->orderBy('purchase_date', 'desc')
                        ->paginate($resultsPerPage);


    return view('backend.events.tickets.index')
        ->with('tickets', $tickets);
}

Key Points

• Parsing the Date: We use Carbon::createFromFormat('d/m/Y', $date) to parse the date from the dd/mm/yyyy format.
• Setting Start and End of Day: We use startOfDay() and endOfDay() to ensure the entire day is included in the filter.
• Applying the Filter: The whereBetween method is used to filter the results within the specified date range.

Why This Matters

By including the entire end date in your filter, you ensure that no records are missed. This is particularly important in applications where accuracy and completeness of data are crucial, such as financial transactions, event logs, or any system that relies on precise date-based queries.

Conclusion

Adding a date filter that captures the entire date range in Laravel is straightforward with the help of Carbon. By parsing the date correctly and using startOfDay() and endOfDay(), you can ensure that your filters work as expected and include all relevant records.

Happy coding!
