Question

所以我正在使用plupload / codeigniter开发一个项目。我在一个名为upload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上尝试了几种变体而没有成功。

脚本无法打开临时目录。我试图在目录上使用CHMOD 755但没有成功。它仍然在我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");
    header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
    header("Cache-Control: no-store, no-cache, must-revalidate");
    header("Cache-Control: post-check=0, pre-check=0", false);
    header("Pragma: no-cache");

    //$targetDir = SITE_WEB_DIR . 'nfsopslag/klachten/';
    //$targetDir = '..'. SITE_WEB_DIR . 'nfsopslag/klachten/';
    $targetDir = "../../../nfsopslag/klachten";

    $cleanupTargetDir = false; // Remove old files
    $maxFileAge = 5 * 3600; // Temp file age in seconds

    // 5 minutes execution time
    @set_time_limit(5 * 60);

    // Uncomment this one to fake upload time
    // usleep(5000);

    // Get parameters
    $chunk = isset($_REQUEST["chunk"]) ? intval($_REQUEST["chunk"]) : 0;
    $chunks = isset($_REQUEST["chunks"]) ? intval($_REQUEST["chunks"]) : 0;
    $fileName = isset($_REQUEST["name"]) ? $_REQUEST["name"] : '';

    // Clean the fileName for security reasons
    $fileName = preg_replace('/[^\w\._]+/', '_', $fileName);

    // Make sure the fileName is unique but only if chunking is disabled
    if ($chunks < 2 && file_exists($targetDir . DIRECTORY_SEPARATOR . $fileName)) {
        $ext = strrpos($fileName, '.');
        $fileName_a = substr($fileName, 0, $ext);
        $fileName_b = substr($fileName, $ext);

        $count = 1;
        while (file_exists($targetDir . DIRECTORY_SEPARATOR . $fileName_a . '_' . $count . $fileName_b))
            $count++;

        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"}');


    // 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"];

    // Handle non multipart uploads older WebKit versions didn't support multipart in HTML5
    if (strpos($contentType, "multipart") !== false) {
        if (isset($_FILES['file']['tmp_name']) && is_uploaded_file($_FILES['file']['tmp_name'])) {
            // Open temp file
            $out = fopen("{$filePath}.part", $chunk == 0 ? "wb" : "ab");
            if ($out) {
                // Read binary input stream and append it to temp file
                $in = fopen($_FILES['file']['tmp_name'], "rb");

                if ($in) {
                    while ($buff = fread($in, 4096))
                        fwrite($out, $buff);
                } else
                    die('{"jsonrpc" : "2.0", "error" : {"code": 101, "message": "Failed to open input stream."}, "id" : "id"}');

    } else {
        // Open temp file
        $out = fopen("{$filePath}.part", $chunk == 0 ? "wb" : "ab");
        if ($out) {
            // Read binary input stream and append it to temp file
            $in = fopen("php://input", "rb");

            if ($in) {
                while ($buff = fread($in, 4096))
                    fwrite($out, $buff);
            } else
                die('{"jsonrpc" : "2.0", "error" : {"code": 101, "message": "Failed to open input stream."}, "id" : "id"}');

            fclose($in);
            fclose($out);
        } else
            die('{"jsonrpc" : "2.0", "error" : {"code": 102, "message": "Failed to open output stream."}, "id" : "id"}');
    }

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

}

主要是Plupload自定义上传的标准代码。它曾经使用$ targetDir =“../../../nfsopslag/klachten”;当我将代码放在控制器外部但将其迁移到不再起作用的开发环境之后。

我尝试在线搜索，但没有找到溶剂。所以我坚持这个。有人有想法或建议吗？

好吧，弄清楚代码首先是不完整的。其次，我们不想删除旧文件，所以我们通过删除它来编辑代码：

// 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"}');

正如你所看到的，它错过了一些标签。变量$ cleanupTargetDir为false。谢谢你的支持。
