在我的CodeIgniter项目中，我在项目创建期间上传文件。这是上传功能：
function uploadFiles(){
$this->load->library('upload');
$error = 0;
$projectName = $_POST['projectname'];
mkdir('./uploads/'.$projectName);
for($i=0; $i<count($_FILES); $i++)
{
$_FILES['userfile']['name'] = $_FILES['files']['name'][$i];
$_FILES['userfile']['type'] = $_FILES['files']['type'][$i];
$_FILES['userfile']['tmp_name'] = $_FILES['files']['tmp_name'][$i];
$_FILES['userfile']['error'] = $_FILES['files']['error'][$i];
$_FILES['userfile']['size'] = $_FILES['files']['size'][$i];
$config['upload_path'] = './uploads/'.$projectName;
$config['allowed_types'] = 'xml|etl';
$config['max_size'] = '0';
$config['overwrite'] = TRUE;
$this->upload->initialize($config);
if($this->upload->do_upload())
{
$error += 0;
}else{
$error += 1;
}
}
if($error > 0){ return FALSE; }else{ return TRUE; }
}
我在create_project函数中调用此函数，如下所示：
public function create_project() {
$this->load->library('form_validation');
$this->form_validation->set_rules('projectname', 'Project name', 'required');
$this->form_validation->set_message('required', 'This is an obligatory field');
if($this->form_validation->run() == FALSE) {
$this->load->view('project_creation_view');
} else {
$this->load->model('Project_management_model');
$this->Project_management_model->create_project();
$this->uploadFiles();
}
}
然而，这没有任何作用。文件未上传。甚至没有创建空目录。有人能帮我找到错误吗？
感谢。

您可以上传任意数量的文件..
$config['upload_path'] = 'upload/Main_category_product/';
$path=$config['upload_path'];
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = '1024';
$config['max_width'] = '1920';
$config['max_height'] = '1280';
$this->load->library('upload', $config);
foreach ($_FILES as $fieldname => $fileObject) //fieldname is the form field name
{
if (!empty($fileObject['name']))
{
$this->upload->initialize($config);
if (!$this->upload->do_upload($fieldname))
{
$errors = $this->upload->display_errors();
flashMsg($errors);
}
else
{
// Code After Files Upload Success GOES HERE
}
}
}

这是我修改为上传多个文件的CI_Upload类的扩展，只需将其复制到MY_Upload.php文件即可。它也会创建目录。
然后，您需要在控制器功能中执行的操作是将文件排列到一个数组中，其中字段的名称和键是数组键，配置是数据。在你的情况下像这样：
$project_files['files'][0] = array(
'upload_path' => './uploads/'.$projectName.'/',
'max_size' => 0,
'allowed_types' => 'xml|etl',
'overwrite' => TRUE,
'remove_spaces' => TRUE,
);
$project_files['files'][1] = array(
'upload_path' => './uploads/'.$projectName.'/',
'max_size' => 0,
'allowed_types' => 'xml|etl',
'overwrite' => TRUE,
'remove_spaces' => TRUE,
);
如果所有文件配置相同，只需进行一个for循环来设置它，它也将采用'命名键'，即。 $project_files['files']['file_key']。
然后打电话：
if($this->upload->upload_files($project_files)){/*all files uploaded successfully*/}

由于我的声誉级别，我无法发表评论，但Zoom根据接受的答案对$ fieldname变量进行了评论，该变量是导致错误的数组。我在回答中遇到了同样的问题，发现这是因为我在表单上添加了所有文件输入名称[]，这使得php将这些输入作为数组变量。要解决该问题，只需为每个文件输入一个唯一的名称，而不是使其成为PHP数组。在我这样做之后，问题就消失了，接受的答案就像一个魅力。我只是想把这些信息传递给其他任何偶然发现这个问题的人。

我想你错过了这个：
$config['file_name'] = 'somename_'.$i; $config['upload_path'] = './uploads/'.$projectName; ...

以为我之前在这里看过同样的问题;）
尝试输出$ this-＆gt; upload-＆gt; display_errors（），其中您正在递增$ error变量。那会告诉你究竟出了什么问题。我的钱是关于权限......

我修改了Cubed Eye的MY_upload以返回上传的所有文件的文件信息。实际上，在调用数据方法时只能访问最后一个文件的信息。我还将上传者的IP地址添加到该列表中。
可以通过以下方式使用：
$upload_files = $this->upload->upload_files($project_files);
if ($upload_files->status == true)
{
$fileInfo = $uploaded_files->file_info;
}
我意识到这对于Cubed Eye的编辑会更好，但这是我的第一篇文章，我没有声誉。

为简单起见，我已经创建了这个CI帮助文件。您可以从配置文件＆amp;在项目的任何地方使用。只需要3个参数
@fileobject = HTML文件对象的名称
@fileopath =您要上传的文件路径
@filetypes = default *，ex-＆＃39; jpg | png | mp4 | pdf＆＃39;
function fileUploader($fileobject, $filepath = "uploads/", $filetypes = "*"){
// retrieve the number of images uploaded;
$number_of_files = sizeof($_FILES[$fileobject]['tmp_name']);
// considering that do_upload() accepts single files, we will have to do a small hack so that we can upload multiple files. For this we will have to keep the data of uploaded files in a variable, and redo the $_FILE.
$files = $_FILES[$fileobject];
$errors = array();
$file_arr = array();
$result = array();
// first make sure that there is no error in uploading the files
for ($k = 0; $k < $number_of_files; $k++) {
if ($_FILES[$fileobject]['error'][$k] != 0) $errors[$k][] = 'Couldn\'t upload file ' . $_FILES[$fileobject]['name'][$k];
}
if (sizeof($errors) == 0) {
// now, taking into account that there can be more than one file, for each file we will have to do the upload
// we first load the upload library
$CI =& get_instance();
$CI->load->library('upload'); // load library
// next we pass the upload path for the images
$config['upload_path'] = FCPATH . $filepath;
// also, we make sure we allow only certain type of images
$config['allowed_types'] = $filetypes;
//$config['max_size'] = (int)(ini_get('upload_max_filesize'));
$config['max_size'] = '10000';
$config['overwrite'] = FALSE;
for ($i = 0; $i < $number_of_files; $i++) {
$_FILES['uploadedimage']['name'] = $files['name'][$i];
$_FILES['uploadedimage']['type'] = $files['type'][$i];
$_FILES['uploadedimage']['tmp_name'] = $files['tmp_name'][$i];
$_FILES['uploadedimage']['error'] = $files['error'][$i];
$_FILES['uploadedimage']['size'] = $files['size'][$i];
//now we initialize the upload library
$CI->upload->initialize($config);
// we retrieve the number of files that were uploaded
if ($CI->upload->do_upload('uploadedimage')) {
$imageup = $CI->upload->data();
// print_r($imageup["orig_name"]);die;
array_push($file_arr, $imageup["orig_name"]);
$result["response"] = "true";
$result["message"] = "Files uploaded successfully.";
$result["files"] = $file_arr;
} else {
$result["response"] = "false";
$result["message"][$i] = $CI->upload->display_errors();
}
}
} else {
$result["response"] = "false";
$result["message"] = $errors;
}
return $result;}
经测试＆amp;证实。
