**Controller File**

Answer 1

这个问题已经回答here

$这个 - >输入 - >后（ 'IMG'）的模式将无法正常工作，以获取图像信息。因为图像存储在$ _FILES而不是$ _POST中。因此，您需要像下面一样使用codeignitor中的上传库。

此外，请确保您的形式包含ENCTYPE = “的multipart/form-data的” ATTR和字段类型是BLOB在数据库中。

Answer 2

我会给你一个例子。这是控制器部分。

public function add() 
{  

     if (empty($_FILES['image']['name'])) 
      {$this->session->set_flashdata('yes', 'Please Upload an image'); 
       redirect($_SERVER['HTTP_REFERER']); 
      } 
     else 
      { 
       $target_dir = "images/products/"; 
       $target_file = $target_dir . time().basename($_FILES["image"]["name"]); 
       $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); 
       $imgName = time().basename($_FILES["image"]["name"]); 
    move_uploaded_file($_FILES["image"]["tmp_name"],$target_file); 
$this->adminmodel->addproducts($imgName); 
} 
} 

Model部分

public function addproducts($imgName) 
    { 
     $data = array(
       'name'    => $this->input->post('name'), 
       'category'  => $this->input->post('category'), 

       'image'    => $imgName 

        ); 
     $this->db->insert('products', $data); 
     $this->session->set_flashdata('yes', 'Product added successfully'); 
     redirect('admin/products/productlist'); 
    } 

视图部分（表格）

形式的作用= “形式” 行动= “管理/产品/添加” 方法= “邮报” ENCTYPE =” multipart/form-data“id =”contact-form“>

您的表格应包含enctype =”multipart/form-data“
