codeigniter multiple search function - php

Question

I am trying to develop a search function in php using codeigniter framework. It should be able to search using the time and the hall too. it works when i use only the time.But it gets very wrong when i use hall.following i have attached all the codes i am using.
I have divided Model into two sections like model and service. in the model there are getters and setters.In the service class only i am writing querys.if anyone can give me a positive answer that would be very helpful. Thanks in advance.
Model(reservation_service.php)
function search_reservations($time,$hall) {
$this->db->select('reservations.*');
$this->db->from('reservations');
$this->db->like('time', $time);
$this->db->or_like('hall',$hall);
$this->db->where('is_deleted', '0');
$query = $this->db->get();
return $query->result();
}
Controller(dashboard.php)
function search_results() {
$reservation_service = new Reservation_service();
$time_booking = trim($this->input->post('time', TRUE));
$hall_booking = trim($this->input->post('hall', TRUE));
$data['search_results'] = $reservation_service->search_reservations($time_booking,$hall_booking);
$partials = array('content' => 'dashboard/search_results');
$this->template->load('template/main_template', $partials, $data);
}
function search_reservations() {
$reservation_service = new Reservation_service();
$data['search_results'] = $reservation_service->search_reservations(trim($this->input->post('time', TRUE)));
$partials = array('content' => 'dashboard/reservation_report');
$this->template->load('template/main_template', $partials, $data);
}
view
reservation_report.php
<div class="form-group"><br>
<input id="time" name="time" type="text" placeholder="Time Slot">
<input id="hall" name="hall" type="text" placeholder="Hall">
<button class="btn btn-primary" onclick="search()" >Search</button>
</div>
<div id="search_results">

</div>
<script type="text/javascript">
function search() {
var time = $('#time').val();
$.ajax({
type: "POST",
url: '<?php echo site_url(); ?>/dashboard/search_results',
data: "time=" + time,
success: function(msg) {
$('#search_results').html(msg);
}
});
}
</script>
search_results.php
<div class="adv-table">

<tbody>
<?php
$i = 0;
foreach ($search_results as $result) {
?>
<tr id="bookings_<?php echo $result->id; ?>">
<td><?php echo ++$i; ?></td>
<td><?php echo $result->date; ?></td>

<?php } ?>

</div>

Answer 1

Problem is with ajax function here you are not sending the value of hall variable in post
<script type="text/javascript">
function search() {
var time = $('#time').val();
var hall = $('#hall').val();// add this to your code
$.ajax({
type: "POST",
url: '<?php echo site_url(); ?>/dashboard/search_results',
data: {time:time,hall:hall},//pass parameter
success: function(msg) {
$('#search_results').html(msg);
}
});
}
</script>

Answer 2

Your code seems to be wrong when loading model in dashboard.php:
$reservation_service = new Reservation_service();
Try to load your model object as described in CodeIgniter Documentations:
$this->load->model('reservation_service');
therefore your dashboard.php should be like this:
function search_results() {
$this->load->model('reservation_service');
$time_booking = trim($this->input->post('time', TRUE));
$hall_booking = trim($this->input->post('hall', TRUE));
$data['search_results'] = $this->reservation_service->search_reservations($time_booking,$hall_booking);
$partials = array('content' => 'dashboard/search_results');
$this->template->load('template/main_template', $partials, $data);
}
function search_reservations() {
$this->load->model('reservation_service');
$data['search_results'] = $this->reservation_service->search_reservations(trim($this->input->post('time', TRUE)));
$partials = array('content' => 'dashboard/reservation_report');
$this->template->load('template/main_template', $partials, $data);
}
