php – Codeigniter无法上传图片

我一直在谷歌上搜索2-3个小时,查看与此相关的每个stackoverflow线程.据我所见,很多人都有同感.像许多其他人一样,我无法上传图像,即使它没有显示任何错误.

我真的尝试过任何我在网上找到的东西,但似乎没有什么工作……

我只能用var_dump($_ FILES)看到图像的属性.我想将图像存储到文件夹中,并将其名称存储到数据库中.

调节器

function upload_sl()
{ 
    $config['upload_path'] = 'sliki/samurajsliki/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size'] = '10000';

$this->load->library('upload',$config);
/*$this->upload->initialize($config);*/
/*var_dump($_FILES);*/
if ( ! $this->upload->do_upload())
{
  $error = array('error' => $this->upload->display_errors());

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

  $this->load->view('header_samurajmain');
  $this->load->view('samuraj/admin_samuraj');
  $this->load->view('footer_subpage');
}
}

视图

<?PHP echo $error;?>
                   <div class="center-block" style="width: 30%; height: 50%; clear:both;">
                   <?PHP echo form_open_multipart('admin_page/upload_sl');?>
                    <input type="file" name="userfile" size="20" />

                    <br />

                    <input type="submit" value="Стави нова слика" />
                    </form>
                     </div>

我在档案中找到了这个.我不知道它的工作原理.
也许你想尝试一下.

<form action="admin/#/add_content/do_upload" enctype="multipart/form-data" method="post" accept-charset="utf-8">
      <input type="file" class="mb5" name="userfiles[]" multiple>
</form>

这是控制器.

<?PHP
defined('BASEPATH') OR exit('No direct script access allowed');
class Upload extends CI_Controller {

public function __construct(){
    parent::__construct();
}

public function do_upload()
{
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png';

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

    $files = $_FILES;
    $cpt = count($_FILES['userfile']['name']);
    for($i=0; $i<$cpt; $i++)
    {           
        $_FILES['userfile']['name']= $files['userfile']['name'][$i];
        $_FILES['userfile']['type']= $files['userfile']['type'][$i];
        $_FILES['userfile']['tmp_name']= $files['userfile']['tmp_name'][$i];
        $_FILES['userfile']['error']= $files['userfile']['error'][$i];
        $_FILES['userfile']['size']= $files['userfile']['size'][$i];    

        if($this->upload->do_upload()){
            echo "File ".$_FILES["userfile"]["name"]. " has been uploaded.\n";
        }
        else{
            //Error. this->upload->display_errors();
        }
    }
    header("Location: http://localhost:82/MyCRM/admin/#/add_content");
 }
 }
