在控制器的方法中调用一次 mkdir()

Question

我有一个上传多个文件的表单。上传一次的文件不会上传到唯一的目录中。我现在面临的问题是对于一个用户我想运行一次mkdir()。不知道具体该怎么做。

控制器.php

class Upload_file extends CI_Controller
{
    function __construct()
    {
        parent::__construct();
        $this->load->helper(array('form', 'url'));
    }
    function upload_it()
    {
        $this->load->helper('form');
        $uniqueID = uniqid(); 
        mkdir("application/uploads/".$uniqueID);

        $config['upload_path'] = 'application/uploads/'.$uniqueID;
        $config['allowed_types'] = '*';
        $this->load->library('upload', $config);
        $this->upload->initialize($config);
        $this->upload->set_allowed_types('*');

        $data['upload_data'] = '';
        if (!$this->upload->do_multi_upload('files')) {
            $data = array('msg' => $this->upload->display_errors());

        } 
        else
        {
              $data['upload_data'] = $this->upload->get_multi_upload_data();
        }
        $this->load->vars($data);

        $this->load->view('upload');
    }
}

<form target="upload_target" id="fileupload" method="post" action="<?php echo site_url('upload_file/upload_it'); ?>" enctype="multipart/form-data">

<div class="fileUpload btn btn-warning">
    <span>Browse</span>
    <input id="uploadBtn" type="file" multiple="multiple" name="files[]" class="upload" />
</div>
    <input id="uploadFile" style="width: 160px; margin-top: 30px;float: left;height: 35px;" placeholder="Choose File" disabled="disabled" />
    <button id="btnupload" style="padding: 4.5px; float:left;margin-top: 30px;border-radius: 0px;" disabled="disabled" type="submit" class="btn btn-primary btn-lg"><span class="glyphicon glyphicon-upload"></span></button>

</form>

我不知道我是否理解你的问题，但我想你应该先检查该文件夹是否存在，然后创建它：

if (!file_exists("application/uploads/".$uniqueID)) {
    mkdir("application/uploads/".$uniqueID);
}
