Plupload上传的文件名问题

问题描述

我已经成功地在移植了plupload为codeigniter ，但是当用户上传一个文件，文件名出来是这样的：_1，_2，_3等

I have been successful in porting over plupload into Codeigniter, but when a user uploads a file, the filename comes out like this: _1, _2, _3, etc.

什么引起此错误？

下面是我的codeIgniter控制器：

Here is my CodeIgniter Controller:

function do_upload($fileName) {
        // Settings
            $targetDir = getcwd() . "/uploads/";
            $cleanupTargetDir = false; // Remove old files
            $maxFileAge = 60 * 60; // Temp file age in seconds
            // 5 minutes execution time
            @set_time_limit(5 * 60);
            // usleep(5000);
            // Get parameters
            $chunk = isset($_REQUEST["chunk"]) ? $_REQUEST["chunk"] : 0;
            $chunks = isset($_REQUEST["chunks"]) ? $_REQUEST["chunks"] : 0;
            // Clean the fileName for security reasons
            $fileName = preg_replace('/[^\w\._]+/', '', $fileName);
            // Create target dir
            if (!file_exists($targetDir))
                @mkdir($targetDir);
            // Remove old temp files
            if (is_dir($targetDir) && ($dir = opendir($targetDir))) {
                while (($file = readdir($dir)) !== false) {
                    $filePath = $targetDir . DIRECTORY_SEPARATOR . $file;
                    // Remove temp files if they are older than the max age
                    if (preg_match('/\\.tmp$/', $file) && (filemtime($filePath) < time() - $maxFileAge))
                        @unlink($filePath);
                }
                closedir($dir);
            } else
                die('{"jsonrpc" : "2.0", "error" : {"code": 100, "message": "Failed to open temp directory."}, "id" : "id"}');
            // Look for the content type header
            if (isset($_SERVER["HTTP_CONTENT_TYPE"]))
                $contentType = $_SERVER["HTTP_CONTENT_TYPE"];
            if (isset($_SERVER["CONTENT_TYPE"]))
                $contentType = $_SERVER["CONTENT_TYPE"];
            if (strpos($contentType, "multipart") !== false) {
                if (isset($_FILES['file']['tmp_name']) && is_uploaded_file($_FILES['file']['tmp_name'])) {
                    // Open temp file
                    $out = fopen($targetDir . DIRECTORY_SEPARATOR . $fileName, $chunk == 0 ? "wb" : "ab");
                    if ($out) {
                        // Read binary input stream and append it to temp file
                        $in = fopen($_FILES['file']['tmp_name'], "rb");

                                fwrite($out, $buff);
                        } else
                            die('{"jsonrpc" : "2.0", "error" : {"code": 101, "message": "Failed to open input stream."}, "id" : "id"}');
                        fclose($out);
                        unlink($_FILES['file']['tmp_name']);
                    } else
                        die('{"jsonrpc" : "2.0", "error" : {"code": 102, "message": "Failed to open output stream."}, "id" : "id"}');

推荐答案

我知道这是一个老问题，你可能想通了 - 但对于其他人谁遇到像我：在的configs，或绑定，任何plupload功能，你的JavaScript函数 - 你在上和文件PARAMS传递？例如：flashuploader.bind（BeforeUpload'，功能（上，文件）{// TODO}）;

I know this is an old question, and you probably figured it out - but for anyone else who comes across it like me:In your javascript function that configs, or binds, any of the plupload functions - are you passing in 'up' and 'file' params?e.g.: flashuploader.bind('BeforeUpload', function(up,file){//TODO});

向上和文件的成员以及pluploads线的地方 - 只是不知道究竟是哪里来的。

'up' and 'file' are members somewhere along the line of pluploads - just not sure exactly where they come from.

起初，我只是路过的'文件'阵列和名字是不确定的，但'身份证'存在的 - 不可思议。但是，增加上固定我的问题的参数列表。

Initially I was only passing in the 'file' array and the name was undefined, but the 'id' existed - weird. But, adding 'up' to the param list fixed my issues.
