我正在使用codeigniter上载类上载文档文件。我需要重命名该文件。这是我的代码

$doc_id=0;
    if(isset($_FILES['doc_file']['name'])){ 



 $config['file_name'] = date('Y/m/d H:i:s').pathinfo($_FILES["doc_file"]
 ['name'], PATHINFO_EXTENSION); 
 $config['upload_path'] = './uploads/';
 $config['overwrite'] = 'FALSE';
 $config['max_filename'] = '300';
 $config['encrypt_name'] = 'TRUE';
 $config['remove_spaces'] = 'TRUE';
 $config['allowed_types'] = '*';
 $config['max_size'] = $this->settings->info->file_size;


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


        if ( ! $this->upload->do_upload('doc_file'))
        {
                $error = array('error' => $this->upload->display_errors());

                $this->template->jsonError(lang("error_152") . "<br /><br />" .
                     $this->upload->display_errors() . "<br />" . mime_content_type($_FILES['doc_file']['tmp_name']));
        }

                                $data = array('upload_data' => $this->upload->data());


        $doc_id = $this->feed_model->add_doc(array(


            "file_name" => $data['file_name'],
            "file_type" => $data['file_type'],
            "extension" => $data['file_ext'],
            "file_size" => $data['file_size'],

            "userid" => $this->user->info->ID,
            "timestamp" => time()
            )
        );
    }
$doc\u id=0;
如果(isset($_FILES['doc_file']['name']){
$config['file_name']=日期('Y/m/d H:i:s')。路径信息($_FILES[“doc_file”]
['name'],路径信息_扩展名);
$config['upload_path']='./uploads/';
$config['overwrite']='FALSE';
$config['max_filename']='300';
$config['encrypt_name']='TRUE';
$config['remove_spaces']='TRUE';
$config['allowed_types']='*';
$config['max\u size']=$this->settings->info->file\u size;
$this->load->library('upload',$config);
如果(!$this->upload->do_upload('doc_file'))
{
$error=array('error'=>$this->upload->display_errors());
$this->template->jsonError(lang(“error_152”)。“

”。 $this->upload->display_errors()。“
”。mime_内容类型($_FILES['doc_file']['tmp_name']); } $data=array('upload_data'=>$this->upload->data()); $doc\u id=$this->feed\u model->add\u doc(数组)( “文件名”=>$data[“文件名”], “文件类型”=>$data[“文件类型”], “扩展名”=>$data['file\u ext'], “文件大小”=>$data[“文件大小”], “userid”=>this->user->info->ID, “时间戳”=>time() ) ); }

现在我想要文件名作为上载的日期。我如何才能做到这一点?

将所有
upload->initialize()
code移到这将使您更好地了解配置

$newName = "my-file".date('Y/m/d H:i:s')".".pathinfo($_FILES["fileName"]['name'], PATHINFO_EXTENSION);

$config['upload_path'] = './uploads/';
$config['overwrite'] = '';
$config['max_filename'] = '';
$config['encrypt_name'] = '';
$config['remove_spaces'] = '';
$config['allowed_types'] = '';
$config['max_size'] = '';
$config['file_name'] = $newName; # add this

$this->load->library('upload', $config); # or $this->upload->initialize($config)
或者你可以使用

$config['encrypt_name']=TRUE


在你的代码中。它会将文件重命名为一些随机字符串

看看:
$this->upload->initialize(数组(“upload\u path”=>。/uploads/”,“file\u name”=>“time()。$\u FILES['doc\u file']['name'],“overwrite”=>FALSE,“max\u filename”=>300,“encrypt\u name”=>TRUE,“remove\u spaces”=>TRUE,“allowed\u type”=>“*”,“最大大小”=>$this->settings->info->file\u size,)
此选项正确吗?给出错误


尝试将上载的文件移动到最终目标时遇到问题。


application/
在上载之前从未获得上载目录的权限。如果移动到上载目录,则会显示错误,如
尝试时遇到问题要将上传的文件移动到最终目的地
是否指定了上传文件的目的地,如$config['upload_path']='./uploads/';使用上面的代码可以很好地工作,只需检查您犯的错误。请在代码中添加一些解释,以便其他人可以从中学习。添加了解释。@Tassadaq Hussain给出的答案也是正确的
you can use this 

    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png|pdf';
    $config['max_size'] = 100;
    $config['max_width'] = 1024;
    $config['max_height'] = 768;
    $config['file_name'] =time().'-'.date("Y-m-d").'-'.$_FILES['userfile']['name'];
    $this->load->library('upload', $config);

    if (!$this->upload->do_upload()) {
        $error = array('error' => $this->upload->display_errors());

        $this->load->view('welcome_message', $error);
    } else {



        $data = array('upload_data' => $this->upload->data());

        $this->load->view('upload_success', $data);
    }
$config['file_name'] = date("Y-m-d_His") . '-' . $_FILES['userfile']['name'];
