控制器（图库）

public function gallery()
{

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

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

        $this->upload->initialize($this->set_upload_options());
        // $this->upload->do_upload('files[]');
        if (!$this->upload->do_upload('files[]'))
        {  
            $error =['error' => $this->upload->display_errors()];
            $this->load->view('admin/addGallery', $error);
        }
    }
}
public function set_upload_options()
{
    $config['upload_path'] = getcwd().'/upload/';
    $config['allowed_types'] = 'gif|jpg|jpeg|png';
    $config['remove_spaces'] = true;
    return $config;
}

Answer 1

我认为你需要更改这一行：

if (!$this->upload->do_upload('files[]'))

至

if (!$this->upload->do_upload('files'))

Answer 2

试试这个：

      $files = $_FILES;
        $cpt = count($_FILES['files']['name']);
         for($i=0; $i<$cpt; $i++)
        {
        $_FILES['files']['name']= $files['files']['name'][$i];
        $_FILES['files']['type']= $files['files']['type'][$i];
        $_FILES['files']['tmp_name']= $files['files']['tmp_name'][$i];
         $_FILES['files']['error']= $files['files']['error'][$i];
         $_FILES['files']['size']= $files['files']['size'][$i];
        $this->upload->initialize($this->set_upload_options());
        $this->upload->do_upload();
        $fileName = $_FILES['files']['name'];
         $images[] = $fileName;

并创建函数 set_upload_options()

$config = array();
         $config['upload_path'] = './upload/'; //give the path to upload the image in folder
         $config['allowed_types'] = 'gif|jpg|png';
          $config['max_size'] = '0';
         $config['overwrite'] = FALSE;
  return $config;

Answer 3

默认情况下，codeIgniter 不支持多文件上传。所以你可以使用这个图书馆 CodeIgniter Multiple Upload Library

Answer 4

你没有通过文件名上传function.Try这个。

if (!$this->upload->do_upload($_FILES['files']['name']))
        {  
            $error =['error' => $this->upload->display_errors()];
            $this->load->view('admin/addGallery', $error);
}

Answer 5

请尝试以下

for($i=0; $i<$cpt; $i++)
{           
    $_FILES['files'] =  $files[$i];
    $this->upload->initialize($this->set_upload_options());
    if (!$this->upload->do_upload('files'))
    {  
        $error =['error' => $this->upload->display_errors()];
        $this->load->view('admin/addGallery', $error);
    }
}

Answer 6

您可以在单个请求中使用 CodeIgniter 上传多个文件。您只需要为每个文件执行 do_upload()。这是一个实现。如果需要，您可以将其放入循环中。

    // Image upload Config
    $config['upload_path']   = './uploads/';
    $config['allowed_types'] = 'gif|jpg|jpeg|png';
    $config['max_size']      = '1000000';
    $config['encrypt_name']  = TRUE;
    $this->load->library('upload', $config);

    // Upload Files
    if ( $_FILES['first_file']['name'] && $this->upload->do_upload('first_file') ) {
        $first_file = $this->upload->data();
    }
    if ( $_FILES['second_file']['name'] && $this->upload->do_upload('second_file') ) {
        $second_file= $this->upload->data();
    }

Answer 7

只是我从图书馆了解到 $this->upload->do_upload('inputelementname') 不必输入元素名称。应该是files数组的key。

所以在这种情况下这应该有效

if($_FILES){
              $filecount=count($_FILES['addmediaelement']['name']);
              for($i=0; $i<$filecount; $i++){
                  $_FILES['mediaelement']['name']=$_FILES['addmediaelement']['name'][$i];
                  $_FILES['mediaelement']['type']=$_FILES['addmediaelement']['type'][$i];
                  $_FILES['mediaelement']['tmp_name']=$_FILES['addmediaelement']['tmp_name'][$i];
                  $_FILES['mediaelement']['error']=$_FILES['addmediaelement']['error'][$i];
                  $_FILES['mediaelement']['size']=$_FILES['addmediaelement']['size'][$i];

                  $config['upload_path']=path/to/save/file;
                  $config['file_name']=filealternatename.extension;
                  $config['max_size']=MAXSIZE; //max size constant
                  $config['max_width']=MAXWIDTH; //max width constant
                  $config['max_height']=CMPMAXHEIGHT; //max height constant
                  $config['allowed_types']='jpg|png';

                  if(!is_dir($config['upload_path'])){
                      mkdir($config['upload_path'], 0775);
                  }
                  $this->upload->initialize($config);
                  $imageuploaderres[]=$this->upload->do_upload('mediaelement');
              }
          }
