php - 如何删除数据库中的图像和codeigniter中的路径

Question

我有一个图像上传表单，我已成功上传图像并尝试删除图像，但它只删除数据库，我不知道如何删除路径。(如何使用取消链接)这是我的代码

     function deleteconf($data){
         $update_id=$this->uri->segment(3);
         $query= $this->_delete($update_id);
         redirect('banner/manage');
     }

    function upload(){ 
     if($this->input->post('upload')){
       $data['banner_name']    =$this->input->post('banner_name',TRUE);
       $data['banner_img1']    =$_FILES['files']['name'][0];
       $config=array(
        'allowed_types' => 'jpg|jpeg|png|gif',
        'upload_path' => $this->gallery_path,
        'max_size' => '2000'
        );

        $this->load->library('upload');
        $this->upload->initialize($config); 
        if($this->upload->do_upload()){
              $data['images']=$this->save_gallery($data);
            }else{
            echo $this->upload->display_errors();
        }
        $image_data=$this->upload->data();
    }
        $data['images']=$this->get_images();
        $data['view_file']='banner_form';
        $this->load->module('template');
        $this->template->one_col_temp($data);
}

您可以使用 unlink 并将其传递给您的图像路径例如

@unlink('MY_UPLOAD/file1.jpg');
