Search is not working in codeigniter - codeigniter

Question

i did search like this but it is not taking passed value in text box,can any one help me to solve this issue..thanks in advances........my model query is correct or any error is there......
if i enter in search term it is redirecting to search results page but it is showing blank results.......and it is saying invalid argument supplied for foreach()
if i print last_query() in that it is showing Like below.....
SELECT * FROM (`clients`) WHERE `clientName` LIKE '%%'
This is My Controller:
class Client extends CI_Controller{
public function __construct(){
parent::__construct();
$this->load->model("client_model");
$this->load->model("interview_model");
$this->load->model("candidate_model");
$this->load->model("requirement_model");
}
function search()
{
$search_term = $this->input->post('search');
$data['query'] = $this->client_model->search_client($search_term);
echo "<pre>"; print_R($this->db->last_query()); exit;
$data['page_title'] = "Search Results";
$this->layout->view("client/search",$data);
}
}
Model:
function search_client($search_term)
{
$this->db->select('*');
$this->db->from('clients');
$this->db->like('clientName',$search_term);
// Execute the query.
$query = $this->db->get();
// Return the results.
return $query->result_array();
}
This is form in index.php(View):
<form action="<?php base_url();?>client/search">
<input type="text" name="search" id="search" style="width:180px" placeholder="Search here..." />
<input type="submit" value="Search" name="submit" class="btn btn-primary btn-sm" /></form>
This is search.php(view):
<?php foreach($query as $client){ ?>
<tr>
<td><?php echo $client->clientName;?></td>
<td><?php echo $client->clientSName; ?></td></td>
<td>
<?php } ?>

change this line:
<form method="POST" action="<?php base_url();?>client/search">
to this:
<form action="<?php echo base_url();?>client/search">
and try the following approch:
function search_client($search_term){
$this->db->select('*');
$this->db->from('clients');
$this->db->like('clientName',$search_term);
// Execute the query.
$query = $this->db->get();
if($query->num_rows()>0)
return $query->result();
else
return false;
}
