我正在使用WAMP服务器,我想使用CI在数据库中上传图像.数据库中的图像变量是blob数据类型.我的问题如下:
1)如何存储图像而不是文件名以及我应该使用哪些数据类型?
2)如何从数据库中检索图像?
我的控制器代码:
<?php class Image_control extends CI_Controller{
function index()
{
//$this->load->view('image_view');
//$this->Image_model->do_upload();
$data['images']=$this->Image_model->get_images();
$this->load->view('image_view',$data);
}
function do_upload()
{
$config = array(
'allowed_types' => 'jpg|png|bmp',
'upload_path'=>'./images1/',
'max_size'=>2000
);
$this->load->library('upload',$config);
if (!$this->upload->do_upload()) {
$errors[]=array('error'=>$this->upload->display_errors());
$this->load->view('image_view',$errors);
}
$image_path=$this->upload->data();
$file_name=$image_path['file_name'];
$config = array(
'a_name' => $this->input->post('a_name'),
'a_details'=>$this->input->post('a_info'),
'a_photo'=>$file_name
);
$insert=$this->db->insert('animalstore',$config);
return $insert;
}
}
?>
