Php 插入件在编码点火器中工作不正常

我正在尝试将数据插入数据库，我的代码确实添加了一个新行，但是所有的值都是空的。我不知道是什么引起的。该视图位于html模式中。这是我的密码：谢谢你的帮助

控制器：

public function addItem(){
    $save = array(
        'inventoryID' => $this->input->post('rfid'),
        'masterCode' => $this->input->post('masterCode'),
        'itemName' => $this->input->post('itemName'),
        'colorName' => $this->input->post('colorName'),
        'location' => $this->input->post('location'),
        'itemCategory' => $this->input->post('itemCategory'),
        'materialDescription' => $this->input->post('materialDescription'),
        'supplier' => $this->input->post('supplier'),
        'itemDescription' => $this->input->post('itemDescription'),
        'comments' => $this->input->post('comments'),
        'itemCode' => $this->input->post('itemCode'),
        'colorCode' => $this->input->post('colorCode')
    );
    $this->searchModel->form_insert($save);

    //load the header
    $this->load->view('base.php',$save);
    //load the page
    redirect('Search');
    //load the footer
    $this->load->view('footer.php',$save);
}

型号：

函数表单插入（$data）{

视图：

问题是您实际上没有“提交”表单数据。您的按钮链接到正确的控制器/方法，但在使用链接时不会向控制器发送任何数据，即
hi，首先您不需要添加标记
public function addItem（）{print\u r（$this->input->post（））；die（）；然后检查表中的列名是什么？您的SQL表列可能具有错误的数据类型和默认值。显示了您的架构
    // Inserting in Table(inventory) of Database(library)
    $this->load->database();
    $this->db->insert('inventory', $data);
    $inventoryID = $this->db->insert_id();
}
