My search code is not outputting any result on codeigniter - php

Question

Please help!!
I am trying to search database to produce results for my search query but it does not output any result even when the searched term exist in the database
Here is my controller
<?php
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Search extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model("profile_model");
$this->load->model("model_home");
}
public function index(){
$data = array();
$search_term = $this->input->post('search');
if($query = $this->model_home->car_search())
{
$data['car'] = $query;
}
$this->load->view('search_results', $data);
}
}
Here is my model
public function car_search($search_term='default')
{
$this->db->select('*');
$this->db->like('car_make',$search_term);
$this->db->or_like('car_model',$search_term);
$this->db->or_like('car_year',$search_term);
$this->db->or_like('registration_number',$search_term);
$this->db->or_like('engine_number',$search_term);
$this->db->or_like('chasis_number',$search_term);
$query = $this->db->get('cars');
return $query->result_array();
}
My search form
<?php
echo form_open('search');
echo form_input(array('name'=>'search'));
echo form_submit('search_submit','submit');
?>
My search result page
<?php
if(isset($car)) :
foreach($car as $row) {
echo $row['car_make'];
} //<-- moved this line
else :
echo '<h1> Not working </h1>';
endif; ?>
Its always outputting "Not Working"

This code is a bit of a mess, if you tidy it up you will see the error
Your code without all the <?php and ?>
<?php
$count = 1;
if(isset($car)) :
foreach($car as $row) {
$count++;
}
echo $row['car_make']
else :
echo '<h1> Not working </h1>';
endif;
?>
So you should see the } in the wrong place ending the foreach loop, quite easily now, so change it to
<?php
$count = 1;
if(isset($car)) :
foreach($car as $row) {
$count++;
echo $row['car_make'];
} //<-- moved this line
else :
echo '<h1> Not working </h1>';
endif;
?>
As you are getting the Not Working message I have to assume there is a problem with your querying of the database.
Probably as you are not passing the search term into the car_search method call. So try passing the paramter you get from the POSTed data.
public function index(){
$data = array();
if($query = $this->model_home->car_search($this->input->post('search'))) {
$data['car'] = $query;
}
$this->load->view('search_results', $data);
}
You should also look at the default value used in the car_search method as the string 'default' will almost definitely cause the query to return no results.
