Codeigniter 文件上传并保存到数据库的路径以及其他表单内容

Question

这是我的控制器文件，它接收来自视图文件的输入。发布数据将提交给 Add 函数，该函数操作 do upload 函数，该函数从 set_configuration_function 接收配置参数。

public function __construct()
{
    parent::__construct();
    $this->load->model('App/AppModel');//load app model
    $this->load->helper('url');
    $this->load->helper('form');
    $this->load->library('session');
}

public function index()
{
    $this->data['blogs'] = $this->AppModel->get_all(BLOGS_TABLE);
    parent::LOADER('App/Blog/All');
}

public function Add()
{


    if ($_POST && empty($_FILES['blog_file']['name'])) {
        $new_blog = $_POST;
        $this->AppModel->insert(BLOGS_TABLE, $new_blog);
        $this->session->set_flashdata('flashSuccess', 'Blog Created Successfully.');
        $this->index();
    }

    if ($_POST && !empty($_FILES['blog_file']['name'])) {
        $file_name =$this->do_upload();
        $file_name = array($file_name);

        $blog = $_POST;
        $new_blog = array_merge($blog, $file_name);
        $this->AppModel->insert(BLOGS_TABLE, $new_blog);
        $this->session->set_flashdata('flashSuccess', 'Blog Created Successfully.');
        $this->index();
    }
    parent::LOADER('App/Blog/New');
}


function do_upload()
{
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size'] = '100';
    $config['max_width']  = '1024';
    $config['max_height']  = '768';

    $this->load->library('upload', $config);

    if ( ! $this->upload->do_upload())
    {
        $error = array('error' => $this->upload->display_errors());

        $this->load->view('upload_form', $error);
    }
    else
    {
        $data = array('upload_data' => $this->upload->data());

        $this->load->view('upload_success', $data);
    }
}


public function set_upload_options (){

    $config = array();
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png|jpeg';
    $config['max_size'] = '10000000000';
    $config['max_width']  = '1024';
    $config['max_height']  = '768';
    return $config;
}

这是我的查看文件

问题是我收到“您没有选择要上传的文件”的错误消息。

Answer 1

1. 您没有使用set_upload_options() 方法。

2. 您的控制器中缺少输入名称 blog_file。

$this->upload->do_upload('blog_file');
