上传文件到指定的目录命名，比如我需要上传一个文件到/cache/my.txt，固定的位置，固定的命名。

1、创建控制器：/dayrui/App/Demo/Controllers/Upload.php

<?php namespace Phpcmf\Controllers\Admin;class Upload extends \Phpcmf\Common{    // 上传界面    public function index() {        \Phpcmf\Service::V()->assign('upload_url', dr_url('demo/upload/add'));        \Phpcmf\Service::V()->display('upload.html');    }    // 上传处理    function add() {        $file = WRITEPATH.'my.txt';        $rt = \Phpcmf\Service::L('upload')->upload_file([            'save_file' => $file, // 上传的固定文件路径            'form_name' => 'file_data', // 固定格式            'file_exts' => ['txt'], // 上传的扩展名            'file_size' => 10 * 1024 * 1024, // 上传的大小限制            'attachment' => \Phpcmf\Service::M('Attachment')->get_attach_info('null'), // 固定文件时必须这样写        ]);        if (!$rt['code']) {            // 失败了            exit(dr_array2string($rt));        }        // 上传成功了        exit(dr_array2string($rt));    }}

2、创建模板文件：/dayrui/App/Demo/Views/upload.html

{template "header.html"}<link href="{ROOT_THEME_PATH}assets/global/plugins/jquery-fileupload/css/jquery.fileupload.css" rel="stylesheet" type="text/css" /><script src="{ROOT_THEME_PATH}assets/global/plugins/jquery-fileupload/js/jquery.fileupload.js" type="text/javascript"></script><div class="dev" id="fileupload">    <a href="___JavaScript:;" class="fileinput-button btn read"> <i class="fa fa-upload"></i> {dr_lang('上传文件')}<input type="file" name="file_data"> </a></div><script type="text/javascript">    $(function() {        $("#fileupload").fileupload({            disableImageResize: false,            autoUpload: true,            maxFileSize: "10000000000",            url: "{$upload_url}",            dataType: "json",            acceptFileTypes: "*",            maxChunkSize: 0,            progressall: function (e, data) {                // 上传进度条 all            },            add: function (e, data) {                $(".fileupload-progress").hide();                data.submit();            },            done: function (e, data) {                if (data.result.code > 0) {                    dr_tips(data.result.code, data.result.msg);                } else {                    dr_tips(data.result.code, data.result.msg, -1);                }            },            fail: function (e, data) {                //console.log(data.errorThrown);                dr_tips(0, "系统故障："+data.errorThrown, -1);                layer.closeAll('tips');            },        });    });</script>{template "footer.html"}

3、访问上传界面：

/admin.php?s=demo&c=upload&m=index
