filter data between dates along with multiple search queries in laravel

Question

I want to filter the data between dates. I have so many columns from the front end.

Screenshot of front end columns

I have the following code that works fine unless the date filter comes. How can I add the date filter in this code and that will work.

I have provided the blade file code and the controller's function code below.

Answer 1

I found the answer. I solved this problem using Pipeline Design Pattern

 $query = tbl_company::query();

        if ($req->has('state')) {
            $query->whereIn('state', $req->input('state'));
        }

        if ($req->has('district')) {
            $query->whereIn('district', $req->input('district'));
        }
        if ($req['date_of_registration']['start'] && $req['date_of_registration']['end']) {
            $from = Carbon::parse($req['date_of_registration']['start']);
            $to = Carbon::parse($req['date_of_registration']['end']);
            $query->whereBetween(
                DB::Raw("STR_TO_DATE(date_of_registration,'%d-%m-%Y')"),
                [$from, $to]
            );
        }
        if ($req['authorized_capital']['start'] && $req['authorized_capital']['end']) {
            $query->whereBetween(
                "authorized_capital",
                [$req['authorized_capital']['start'], $req['authorized_capital']['end']]
            );
        }

// filtered data.
$data = $query->paginate(100);
