将文件上传到 Web 服务器错误 6 php

[英]upload file to web server error 6 php

我正在尝试从 php 表单上传文件。它在 linux 服务器上不起作用。 我希望它从文件所在的位置将它移动到子目录“/uploads”。

通过echo $_FILES["file_upload"]['error'];执行页面时出现以下错误$_FILES["file_upload"]['error']; 获取错误编号。

它返回:

Upload failed with error code 6

有谁知道这个错误代表什么?

表格代码:

<!DOCTYPE html>
<html>
<body>

<form action="upload.php" method="post" enctype="multipart/form-data">
    Select File to upload:
    <input type="file" name="file_upload" id="file_upload">
    <input type="submit" value="Upload File" name="submit">
</form>

</body>
</html>

上传.php:

<?php

    if(isset($_POST['submit']))
    {
        if($_FILES['file_upload']['name'] != "" )
    {
            $target_dir = "uploads/";
            $target_file = $target_dir . basename($_FILES["file_upload"]["name"]);
            $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
            $uploadOk = 1;
    }
    else
    {
        die("No file specified!");
    }

    // Check if file already exists
    if (file_exists($target_file)) {
        echo "Sorry, file already exists.";
        $uploadOk = 0;
    }

    // Check file size
    if ($_FILES["file_upload"]["size"] > 500000) {
        echo "Sorry, your file is too large.";
        $uploadOk = 0;
    }

    // Allow certain file formats
    if($imageFileType != "txt" && $imageFileType != "xls" && $imageFileType != "xlsx")
     {
        echo "Sorry, only TXT, XLS, XLSX files are allowed.";
        $uploadOk = 0;
    }

    if ($_FILES["file_upload"]['error'] !== UPLOAD_ERR_OK) {
       die("Upload failed with error code " . $_FILES['file_upload']['error']);
    }
    // Check if $uploadOk is set to 0 by an error
    if ($uploadOk == 0) {
        echo "Sorry, your file was not uploaded.";
    // if everything is ok, try to upload file
    } else {
        if (move_uploaded_file($_FILES["file_upload"]["tmp_name"], $target_file)) {
            echo "The file ". basename( $_FILES["file_upload"]["name"]). " has been uploaded.";
        } else {
            echo "Sorry, there was an error uploading your file.";
        }
    }
    }
    ?>

我已经搜索了这个问题并在这里找到了解决方案。 但不能正确理解。

我还授予了/uploads文件夹的完全权限777 任何帮助将不胜感激。 谢谢

UPLOAD_ERR_NO_TMP_DIR

Value: 6; Missing a temporary folder. Introduced in PHP 5.0.3.

修复您的设置..

http://php.net/manual/en/ini.core.php#ini.upload-tmp-dir

我通过在SELinux上使用“setenforce 0”进入permissive模式解决了这个问题;

[root@localhost tequila]# setenforce 0

如果之前文件上传工作正常并且 /tmp 文件夹用于上传文件,则只需重新启动 apache 服务即可解决此问题:

在 ubuntu 中,您可以使用以下命令重新启动 apache 服务:

sudo /etc/init.d/apache2 restart
