Plupload：错误“代码”：100，“消息”：“无法打开临时目录

Question

所以我正在与 plupload/codeigniter 合作一个项目。我在名为上传的函数下的控制器中有自定义 upload.php 的代码。 plupload 的 javascript 嵌入在视图中。但是我在 $targetDir 上尝试了几种变体，但都没有成功。

脚本无法打开临时目录。我尝试在目录上使用 CHMOD 755 但没有成功。它仍然在我的 Mac.

上的本地环境中

function upload() {

    // HTTP headers for no cache etc
    header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");

    }

    // Check if file has been uploaded
    if (!$chunks || $chunk == $chunks - 1) {
        // Strip the temp .part suffix off 
        rename("{$filePath}.part", $filePath);

    }

    // Return JSON-RPC response

    die('{"jsonrpc" : "2.0", "result" : null, "id" : "id", "cleanFileName" : "'.$fileName.'"}');

}

主要是Plupload自定义上传的标准代码。它曾经与 $targetDir = "../../../nfsopslag/klachten" 一起工作；当我的代码在控制器之外，但在将它迁移到不再工作的开发环境之后。

我尝试在网上搜索但没有找到解决方案。所以我坚持这一点。有人有想法或建议吗？

嗯，发现代码首先是不完整的。其次，我们不想删除旧文件，所以我们通过删除这个来编辑代码：

// Remove old temp files    
if ($cleanupTargetDir && is_dir($targetDir) && ($dir = opendir($targetDir))) {
    while (($file = readdir($dir)) !== false) {
        $tmpfilePath = $targetDir . DIRECTORY_SEPARATOR . $file;

        // Remove temp file if it is older than the max age and is not the current file
        if (preg_match('/\.part$/', $file) && (filemtime($tmpfilePath) < time() - $maxFileAge) && ($tmpfilePath != "{$filePath}.part")) {
            @unlink($tmpfilePath);
        }
    }

    closedir($dir);
} else
    die('{"jsonrpc" : "2.0", "error" : {"code": 100, "message": "Failed to open temp directory."}, "id" : "id"}');

如您所见，它遗漏了一些标签。变量 $cleanupTargetDir 为假。谢谢你的包容
