Above code but it will give an error Database error occured. Column name not be null. I am beginner in codeigniter please any suggestions for it.
I want to add data in my database.but it is not working.

Answer 1

Check your table "tbl_vendor" in which you are inserting values. One or more field is defined as NOT NULL means it will not accept empty value. You have to pass value to that field which is marked as NOT NULL.

Answer 2

Please read Codeigniter Query Builder reference first. You're making big mistakes. Your code should be like below:
$vendor_data = array(
'ven_name'=> $this->input->post['firstName'],
'ven_shop'=>$this->input->post['companyName'],
'ven_email_id'=>$this->input->post['email'],
'ven_contactno'=>$this->input->post['contactno'],
'ven_othercontactno'=>$this->input->post['contactno2'],
'ven_commission'=>$this->input->post['assigncommission'],
'ven_accname'=>$this->input->post['bankaccname'],
'ven_accountno'=>$this->input->post['bankaccno'],
'ven_ifsccode'=>$this->input->post['ifsccode'],
'ven_type'=>$this->input->post['optionsRadios']
);
$this->db->insert('your_table_name', $vendor_data);
