计算上传的文件数 [英] Counting the number of uploaded files

问题描述

但是，我需要一些方法来计算上传文件的数量，因为我想限制在某些情况下（但不是全部）。

我该怎么做？我尝试了 count（$ _ FILES）但是这给我没什么用。

，但都没有提供我需要的信息。

上传表单是一个多文件上传，我使用此媒体库可处理多次上传。

无计数功能的上传功能像这样：

  function do_upload（）
 {
 $ setid = $ this-& > post（'imageset'）; 
 $ this-> load-> library（'upload'）; 
 $ this-> load-> library（'image_lib'）; 
 $ this-> upload-> initialize（array（
upload_path=>./photos/，
allowed_types=>jpg | jpeg | png | gif，
encrypt_name=> TRUE 
））; 
 try {
 $ this-> upload-> do_multi_upload（files）; 
 $ images = $ this-> upload-> get_multi_upload_data（）; 
 $ config = array（
'image_library'=>'gd2'，
'create_thumb'=> TRUE，
'maintain_ratio'=> TRUE，
'width'=>'145'，
'height'=>'145'
）; 
 foreach（$ images as $ image）
 {
 $ config ['source_image'] = $ image ['full_path']; 
 $ this-> image_lib-> initialize（$ config）; 
 $ this-> image_lib-> resize（）; 
 $ this-> manage_model-> insertimage（$ image ['file_name']，$ image ['orig_name']，$ image ['file_size']，$ image ['file_type']，$ setid） ; 
} 
 $ this-> session-> set_flashdata（'success'，'Billederne er nu blevet uploadet。'）; 
} catch（Exception $ e）{
 $ this-> session-> set_flashdata（'error'，$ e）; 
} 
 redirect（'manage / images'，'refresh'）; 
} 
  

任何帮助是非常感激。

$ _ FILES 变量中的项目数：

  $ total = count（$ _ FILES ['your_variable_array_in_html'] ['tmp_name']）; 
  

您需要在：

  $ this-> upload-> do_multi_upload（files）; 
  

行。

注意， $ _ FILES 只包含一个变量 - 一个数组，包含不同部分的数组， tmp_name ， name ，错误等。请检查手动了解详情。

I am working on my CodeIgniter project, and it is so far working very well.

However, I need some way to count the number of uploaded files, since I want to limit it in some cases (but not all).

How can I do that? I tried count($_FILES) but that gave me nothing usable.

I also tried a bunch of other things, but neither gave me the information I need.

The upload form is a multiple file upload, and I am using this library to handle multiple uploads.

The upload function without the counting looks like this:

function do_upload()
{
    $setid = $this->input->post('imageset');
        $this->load->library('upload');
        $this->load->library('image_lib');
        $this->upload->initialize(array(
                "upload_path"   => "./photos/",
                "allowed_types" => "jpg|jpeg|png|gif",
                "encrypt_name" => TRUE
        ));
        try {
            $this->upload->do_multi_upload("files");
            $images = $this->upload->get_multi_upload_data();
            $config = array(
                    'image_library'  => 'gd2',
                    'create_thumb'   => TRUE,
                    'maintain_ratio' => TRUE,
                    'width'          => '145',
                    'height'         => '145'
            );
            foreach ($images as $image)
            {
                $config['source_image'] = $image['full_path'];
                $this->image_lib->initialize($config);
                $this->image_lib->resize();
                $this->manage_model->insertimage($image['file_name'],$image['orig_name'],$image['file_size'],$image['file_type'],$setid);
            }
            $this->session->set_flashdata('success','Billederne er nu blevet uploadet.');
        } catch (Exception $e) {
            $this->session->set_flashdata('error', $e);
        }
        redirect('manage/images','refresh');
}

Any help is very appreciated.

解决方案

You can check the number of items in your $_FILES variable using for example:

$total = count($_FILES['your_variable_array_in_html']['tmp_name']);

You need to do that before the:

$this->upload->do_multi_upload("files");

line.

As you have already noticed, $_FILES only contains one variable - an array - containing arrays of the different sections, tmp_name, name, error, etc. Check the manual for more details.
