i got this message in my console when i tried to add details in my detail grid and when i refresh it. it doesn't showing the data i added. my console message was this:

POST http://localhost/comunion/sec_users/detailpost

{"item":null}<br />
<b>Fatal error</b>: ob_start() [&lt;a href='ref.outcontrol'&gt;ref.outcontrol&lt;/a&gt;]: Cannot use output buffering in output buffering display handlers in <b>C:\xampp\htdocs\comunion\system\libraries\Exceptions.php</b> on line <b>162</b><br />

{"item":null}<br />
<b>Fatal error</b>: ob_start() [&lt;a href='ref.outcontrol'&gt;ref.outcontrol&lt;/a&gt;]: Cannot use output buffering in output buffering display handlers in <b>C:\xampp\htdocs\comunion\system\libraries\Exceptions.php</b> on line <b>162</b><br />

POST http://localhost/comunion/sec_users/detaillistview
{
page: 0,
total: 0,
records: 0,
rows: []
}

and i also changed again my code:

CONTROLLER:

Code:

case $crudConfig['create']:
                $c = "";
                $id['company_code'] = $this->input->post('company_code');
                $sec_exist = $this->User->getCompanyDetails($id);
                
                if ($sec_exist)
                {
                    $c .= 'Company ID already exists.';
                    $data['action'] = 'exist';
                }
                else
                {
                $fields = array(
                        "company_code"
                        ,"company_name"
                        );
                
                foreach ($fields as $field)
                {if (isset($_POST[$field])) $id[$field] = $this->input->post($field);}

                $id = $this->input->post("ids");        
                $data['item'] = $this->User->savecompany_details($id);
                }
                break;

MODEL:

Code:

function savecompany_details($id)
    {
        $this->db->where('company_id', $id);
        //$this->db->delete('maint_company');
    
    
        $data['company_id'] = $id;
        $this->db->insert('maint_company', $data);
    
    }

thanks in advance,
