Question

我正在尝试将文件上传到文件夹但无法上传。它给了我错误信息。文件结构为：c:/xampp/htdocs/uploadfile/uploadfile.php，文件夹为c:/xampp/htdocs/uploadfile/abc/

这是我的代码：

uploadfile.php

<form method="post" enctype="multipart/form-data" action="upload.php">
    <input name="userfile" type="file" id="file" /><br />
    <input type="submit" value="Upload Selected File" class="submit" />
</form>

upload.php的

<?php

$allowed =  array('pdf','doc' ,'docx');
$filename = $_FILES['userfile']['name'];
$ext = pathinfo($filename, PATHINFO_EXTENSION);

if(!in_array($ext,$allowed) ) {
    echo 'There is an Error Occured while Uploading. <br><br>Please select right file type and try again.';
}
else {
    $uploaddir = '/abc/';
    $uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
    echo $uploadfile;

    if (move_uploaded_file($_FILES['userfile']['name'], $uploaddir)) {
        echo "<br><br>File is valid, and was successfully uploaded.\n";
    } else {
        echo "Error Occured while uploading file. <br><br>Please try later.";
    }
}

?>

Answer 1

move_uploaded_file（）函数不正确。

move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)

Answer 2

尝试$_FILES['userfile']['tmp_name']

move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile);

还尝试更改

$uploaddir = '/abc/';
到

$uploaddir = 'abc/';或$uploaddir ='./uploadfile/abc/';

Answer 3

Check the folder name is exist and check the permission of that particular folder 

if(!in_array($ext,$allowed) ) {
    echo 'There is an Error Occured while Uploading. <br><br>Please select right file type and try again.';
}
else {
    $uploaddir = 'abc/';
   // $uploadfile =  basename($_FILES['userfile']['name']);
   // echo $uploadfile;

    if (move_uploaded_file($_FILES['userfile']['name'], $uploaddir)) {
        echo "<br><br>File is valid, and was successfully uploaded.\n";
    } else {
        echo "Error Occured while uploading file. <br><br>Please try later.";
    }
}

Answer 4

请检查：

move_uploaded_file($_FILES['userfile']['tmp_name'], $uploaddir)

Answer 5

你应该使用

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploaddir)) {..}

因为PHP首先检查以确保filename指定的文件是有效上传文件（意味着它是通过PHP's HTTP POST上传机制上传并存储在临时文件中地点）。

如果文件有效，它将被移动到目的地给出的文件名。

注意：但是，仅限于目标路径上的限制，以允许移动文件名可能与此类限制冲突的上载文件。 move_uploaded_file()只允许通过PHP上传的文件移动，从而确保此操作的安全性。

如果目标文件已存在，则会被覆盖。

此外，您还可以通过HTTP POST功能is_uploaded_file()检查文件是否已上传。
