undefined variable in codeigniter view which is already defined in the controller - codeigniter

Question

This is my controller. here i declared current_company.
public function index($id='')
{
$this->load->model('Company_model');
($id!='') ? $data["company_details"]=$this->Company_model->get_company($id) :'';
($id!='') ? $data ["current_company"]=$this->Company_model->get_currentcomp($id) :'';
$this->load->view('includes/header');
$this->load->view('includes/left_menu');
$this->load->view('company/manage',($id!='') ? $data : '');
$this->load->view('includes/footer');
}
This is my model. Here i declared the function
class Company_model extends CI_Model{
protected $strTableName = 'suc_company';
function __construct(){
parent::__construct ();
$this->db->from($this->strTableName);
}
function get_currentcomp($intPkId){
$this->db->where('pk_bint_company_id',$intPkId);
$q1 = $this->db->get($this->strTableName);
return $q1->result_array()[0];
}
This is the view part. here i called the $current_company !== FALSE then
<div class="form-group">
<label for="company_package" class="col-sm-3 control-label"> Package</label>
<div class="col-sm-9 col-xs-12">
<?php if ($current_company !== FALSE ) {?>
<select name="company_package" class="form-control select2" disabled="">
<option value="<?php echo $company_package;?>" selected=""><?php echo $packagename;?></option>
</select>
<?php } else { ?>
<?php } ?>
Error
an error is occurring... undefined data current_company

Answer 1

Change your controller code like this.
public function index($id='')
{
$this->load->model('Company_model');
$data["company_details"] = false;
$data["current_company"] = false;
if($id != ''){
$data["company_details"] = $this->Company_model->get_company($id);
$data["current_company"] = $this->Company_model->get_currentcomp($id);
}
$this->load->view('includes/header');
$this->load->view('includes/left_menu');
$this->load->view('company/manage',$data);
$this->load->view('includes/footer');
}

As said in comment, you are leaving possibility that maybe $data wouldn't be passed to view file. You have to restrict this kind of oscillations.
Try this way:
public function index($id='')
{
if ((int)$id < 1) {
redirect('some/generic/place', 'refresh');
}
// we have integer in parameter
// so we will check if data by that parameter exists
$data = [];// initialization of array so we are sure $data is set
$this->load->model('Company_model');
$data['company_details'] = $this->Company_model->get_company($id);
if ($data['company_details']) {
$data['current_company'] = $this->Company_model->get_currentcomp($id) :'';
} else {
// in this point $data is an empty array
}
// $this way variable will be available in all view files
$this->load->var($data);
$this->load->view('includes/header');
$this->load->view('includes/left_menu');
$this->load->view('company/manage');
$this->load->view('includes/footer');
// so now, in your view you would have wether company with details wether an empty array
// *first line of code assumes parameter would be an integer
// **also assumed that $this->Company_model->get_company($id) would return false/null/anEmptyArray if data doesn't exist
}
