insert_batch not insert data

Hi all,
I'm new to code igniter but I love it
I have issue with insert_batch, when I try to save multiple row the script no save data

The array:

Code:

Array ( [0] => Array ( [company_name] => thename0 ) [1] => Array ( [company_name] => thename1 ) [2] => Array ( [company_name] => thename2 ) [3] => Array ( [company_name] => thename3 ) )

The controller:

PHP Code:

       public function index()
        {
                $this->load->helper('file');
                $json = read_file('./myfile.json');
                $obj = json_decode($json);
                $data['json'] = $obj;
                foreach ($data['json']->res as $val) 
                {
                        $batch[] = array(
                                        'company_name' => $val->res->company_name
                                        
                                );
                }
                $this->my_model->get_json_file($batch);

        } 


The model:

PHP Code:

   public function __construct()
    {
            $this->load->database();
    }
    public function get_json_file($data)
    {   
        $this->db->insert_batch('my_table', $data);
    } 


I have not error message in the page but data not present in the DB.

Does just insert work?

Do you have a Primary Key in your table and if it set to Auto Increment?

@ven0m,

Have you looked at the log file to see if any errors are there?
