Codeigniter Insert funktioniert nicht Datenbankfehler

Question

Ich habe folgenden Code ausprobiert.

class Vendor extends CI_Controller{ 

    function __construct(){ 
     parent::__construct(); 
    } 

    public function vendor_add(){ 
      $this->load->helper('url'); 
      $this->load->view('header'); 
      $this->load->view('sidebar'); 
      $this->load->view('add_vendor'); 
      $this->load->view('footer'); 
    } 
     public function save(){ 
      $this->load->helper(array('form','url')); 
      $this->load->model('Save_vendor'); 
      $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'] 
        ); 

      $this->Save_vendor->vendor_insertdata($vendor_data); 

      redirect(base_url().'/vendor/vendor_add'); 
     } 
    } 

/* Model File */ 

    class Save_vendor extends CI_Model{ 
     public function vendor_insertdata($vendor_data){ 
     $this->db->insert('tbl_vendor',$vendor_data); 
    }

Über dem Code, aber es wird einen Fehler geben Datenbankfehler aufgetreten. Spaltenname ist nicht null. Ich bin Anfänger in Codeigniter bitte irgendwelche Vorschläge dafür.

Ich möchte Daten in meiner Datenbank hinzufügen, aber es funktioniert nicht.

Answer 1

Überprüfen Sie Ihre Tabelle "tbl_vendor" in der Sie Werte einfügen. Ein oder mehrere Felder sind definiert als NOT NULL bedeutet, dass kein leerer Wert akzeptiert wird. Sie müssen einen Wert an das Feld übergeben, das als NOT NULL markiert ist.

Answer 2

Bitte zuerst Codeigniter Query Builder reference lesen. Du machst große Fehler. Ihr Code sollte wie folgt sein:
