not displaying result in codeigniter - php

Question

i tried to use print_r($list) but the result array().There is no element in the array.I want to show data form my table.there is user table, job table and industry table.Can anybody suggest me where is mistake.
This is my model function get_data_by_query used in controller
public function get_data_by_query($qry)
{
$query = $this->db->query($qry);
return $query->result();
}
This is my controller where i am verifying email, phone number.
public function Dashboard()
{
if ($this->Common_model->Is_User_Logged())
{
$condition='';
$data['email_verified']=self::IsEmailVerified();
$data['phone_verified']=self::IsPhoneVerified();
$userdata=$this->session->userdata('user_logged_in');
$data['user_email']=$userdata['email'];
//print_r($data);
$res=$this->Common_model->get_data_by_query("SELECT * FROM user WHERE user_id={$userdata['id']} limit 1");
//print_r($res);
$data['user_skills'] = $res[0]->user_skills;
//print_r($data);
$arr = array($res[0]->user_skills);
//print_r($arr[0]);
//exit;
$condition.=" and FIND_IN_SET(job_title,'$arr[0]')";
print_r($condition);
$sql_get="SELECT j.*,j.job_industry,i.industry_title
FROM job j
LEFT JOIN industry i on i.industry_id=j.job_industry
WHERE job_status=1 ".$condition." ";
//print_r($sql_get);
$data['list']=$this->Common_model->get_data_by_query($sql_get);
//print_r($data['list']);
$data['user_phone']=$res[0]->user_mobile;
$this->load->view('user/header');
$this->load->view('user/home', $data);
$this->load->view('user/footer');
}
else
{
redirect('user');
}
}
This is my view
<?php
if(!empty($list)>0)
{
foreach ($list as $row)
{
?>
<tr>
<td><?php echo $row->job_role;?></td>
<td><?php echo $row->industry_title;?></td>
<td><?php echo $row->job_vacancy;?></td>
<td><?php echo $row->job_keyword;?></td>
<!--<td><?php echo $row->job_type;?></td>-->
</tr>
<?php
} }
?>
what is the reason that $list is empty array although i have data in my table. I will be thankful for you.

After a lot of effort, i found that there is no problem in above code. The problem is in tje SQL query. I am trying to resolve that query.
