                    data: $("#meetingform").serialize(),
                    success: function () {
               $('#msg').html('<span style="color:green;align:center;">Data 
                  Posted.</span>');
                        $('#date').val('');
                        $('#subjectt').val('');
                        $('#venuee').val('');
                        $('#desc').val('');
                        $('#momm').val('');
                        $('#photo').val('');
                        $("#msg").delay(3000).fadeOut();
                    },
                    error: function () {
                $('#msg').html('<span style="color:red;">Data didnot post .

                    }
                });
            });
        });

    </script>

my controller

public function meeting_form() {
    $session_data = $this->session->userdata('admin_logged_in');
    $id = $session_data['id'];
    if ($session_data) {
        $this->form_validation->set_rules('meetingdate', 'Meeting Date', 
                 'required');
        $this->form_validation->set_rules('subject', 'Subject', 'required');
        $this->form_validation->set_rules('venue', 'Venue', 'required');
        $this->form_validation->set_rules('description', 'Description','required');
        $this->form_validation->set_rules('mom', 'MOM', 'required');
        if ($this->form_validation->run() == false) 
        {
            $this->load->view('project_monnetering');
        }
        else 
        {
            $data = array('event_date' => date('y-m-d', strtotime($this-
            >input->post('meetingdate'))), 'event_type' => $this->input-
            >post('meetingevent'), 'user_id' => $id,
                'post_description' => $this->input->post('description'));
            $last_id = $this->admin_model->insert_event_master($data);
            $data1 = array('meeting_date' => date('y-m-d', strtotime($this-
           >input->post('meetingdate'))), 'event_id' => $last_id, 'subject' 
               => $this->input->post('subject'),
                'venue' => $this->input->post('venue'), 'brief_desc' => 
             $this->input->post('description'), 'mom' => $this->input-
             >post('mom'));
            $this->admin_model->insert_meeting_details($data1);

Please check below mentioned solution, This will help you to send file with input data.

var myFormData = new FormData();

$(document).on("click", "button", function(e) {
  e.preventDefault();
  var inputs = $('#my_form input[type="file"]');
  $.each(inputs, function(obj, v) {
    var file = v.files[0];
    var filename = $(v).attr("data-filename");
    var name = $(v).attr("id");
    myFormData.append(name, file, filename);
  });
  var inputs = $('#my_form input[type="text"]');
  $.each(inputs, function(obj, v) {
    var name = $(v).attr("id");
    var value = $(v).val();
    myFormData.append(name, value);
  });
  var xhr = new XMLHttpRequest;
  xhr.open('POST', '/echo/html/', true);
  xhr.send(myFormData);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="my_form" enctype="multipart/form-data">
    <input type="file" name="file_1" id="file_1" data-filename="image.jpg">
    <input type="text" name="check1" id="check1"/>
    <input type="text" name="check2" id="check2"/>
    <input type="text" name="check3" id="check3"/>
    <button>click</button>
</form>

Let me know if it not works.
