计算上传的文件数

本文介绍了计算上传的文件数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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.
