How to save multiple inputs in laravel in mysql database?

I have a ticketing system in laravel and my problem is I have multiple input fields in my site which are title fname lasname and that came from the inputs of how many passengers are included. Now I have two tables which are booking and booking_details. I want to save the Contact Details and Mobile Number (which are shown below) to bookings table, and the other input fields like the Title First Name… in the booking_details table referencing the booking_id. I already finished setting the database and the relations of the two tables and now my problem is to save multiple names of the passengers in my booking_details table? That is my only problem. I tried different ways like using the array but I can’t solve it. Maybe the syntax or logic is wrong. Can someone tell me what to do? Thanks in advance.

My Form.

 <form method="POST" action="{{url("/saveBooking")}}">
                        <div class="form-row">
                            <div class="col-sm-6 form-group">
                                <input name="email" class="form-control" id="email" required="" placeholder="Enter Email" type="text">
                            </div>
                            <div class="col-sm-6 form-group">
                                <input name="mobile_no" class="form-control" data-bv-field="number" id="mobileNumber" required="" placeholder="Enter Mobile Number" type="text">
                            </div>
                        </div>
                        <p class="text-info">Your booking details will be sent to this email address and mobile number.</p>

                            @for ($i = 0 ; $i<$split1 ; $i++)
                            <button style="margin: 5px;" type="button" class="btn btn-sm btn-info collapsible" >Passenger <?php echo $i + 1 ?></button>
                            <div class="form-row content"  style=" display: none;margin-top:7px;" >

                                <div class="col-sm-2 form-group" >
                                    <select class="custom-select" id="title" name="title[]" required="">

Answer

Your data is coming as array from the form. So loop over the array and insert values in each iteration. Sample Approach:

public function addBooking(Request $request)
{
    $booking = Booking::create([
        'mobile_no' => $request->mobile_no,
        'email' => $request->email,
        //add if you want you add any more column
    ]);

    foreach ($request->title as $key => $value) {
        BookingDetails::create([
            'booking_id' => $booking_id,
            'title' => $request->title[$key],
            'fname' => $request->fname[$key],
            'lname' => $request->lname[$key],
            //other columns
        ]);
    }

    return->back();
}
