Question

我正在尝试在我的本地服务器上使用php上传文件，并且在运行脚本（这是一个非常简单的脚本）后，应该回显信息的页面只是空白。有人可以帮我弄清楚问题是什么吗？我曾尝试阅读许多不同的帖子，但我似乎无法找到解决方案。感谢

HTML

<form enctype="multipart/form-data" action="upload.php" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
Choose a file to upload: <input name="uploadedfile" type="file" /><br />
<input type="submit" value="Upload File" />
</form>

PHP

<?php 
// Where the file is going to be placed 
$target_path = "tmp/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
$target_path = "tmp/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']); 
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name']). 
    " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again!";
}
?>

我从中得不到任何东西。只是一个空白页...当我检查tmp DIR时，没有任何东西在那里......有什么建议吗？我正在使用XAMP

编辑：

原来这是两部分。＃1 DIR权限，＃2我必须通过服务器的DNS浏览到我的xampp目录。这很奇怪，因为我通常可以通过localhost，它会工作正常。我想问题出在XAMPP本身。

感谢大家的帮助！

临时目录将为空，除非在上传过程中。除非您自己处理，否则PHP会自动删除所有上传的文件。我建议检查你的服务器和php日志以查找错误消息，并且肯定会在你的脚本中添加一些错误处理。你假设上传成功，这不好：

if ($_FILES['uploadedfile']['error'] === UPLOAD_ERR_OK) {
    ... your code here ...
} else {
    die("Upload failed with error code " . $_FILES['uploadedfile']['error']);
}

代码定义为here。

我实际上只是运行了你的代码，它运行得非常好。您可能遇到的唯一问题是权限，请确保/ tmp目录具有0777权限以允许移动文件。这是我运行的代码：

<?php 
// Where the file is going to be placed 
if(isset($_FILES['uploadedfile'])){

$target_path = "img/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
$target_path = "img/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']); 
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name']). 
    " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again!";
}
}
?>


<form enctype="multipart/form-data" action="" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
Choose a file to upload: <input name="uploadedfile" type="file" /><br />
<input type="submit" value="Upload File" />
</form>

php文件上传无效 - 空白页面
