Question

只是玩上传文件，因为它实际上是我以前从未做过的事情。我从here复制了一些所谓的工作代码。

我正在使用Namecheap的cPanel托管，绝对没有更改默认配置。

我认为最可能的问题是我没有激活的非常基本的问题。我的HTML看起来像这样

<html>
<body>
<form action="upload_file.php" method="post" enctype="multipart/form-data">
    Your Photo: <input type="file" name="photo" size="25" />
    <input type="submit" name="submit" value="Submit" />
</form>
</body>
</html>

我的PHP看起来像这样

<?php
//if they DID upload a file...
if($_FILES['photo']['name'])
{
    //if no errors...
    if(!$_FILES['photo']['error'])
    {
        //now is the time to modify the future file name and validate the file
        $new_file_name = strtolower($_FILES['photo']['tmp_name']); //rename file
        if($_FILES['photo']['size'] > (1024000)) //can't be larger than 1 MB
        {
            $valid_file = false;
            $message = 'Oops!  Your file\'s size is to large.';
        }

        //if the file has passed the test
        if($valid_file)
        {
            //move it to where we want it to be
            move_uploaded_file($_FILES['photo']['tmp_name'], 'uploads/'.$new_file_name);
            $message = 'Congratulations!  Your file was accepted.';
        }
    }
    //if there is an error...
    else
    {
        //set that to be the returned message
        $message = 'Ooops!  Your upload triggered the following error:  '.$_FILES['photo']['error'];
    }
}

//you get the following information for each file:
$_FILES['field_name']['name']
$_FILES['field_name']['size']
$_FILES['field_name']['type']
$_FILES['field_name']['tmp_name']
}

当我尝试上传图片时，点击提交时出现500内部服务器错误。

我错过了什么？

摆脱底部的东西：

<?php
//if they DID upload a file...
if($_FILES['photo']['name'])
{
    //if no errors...
    if(!$_FILES['photo']['error'])
    {
        //now is the time to modify the future file name and validate the file
        $new_file_name = strtolower($_FILES['photo']['tmp_name']); //rename file
        if($_FILES['photo']['size'] > (1024000)) //can't be larger than 1 MB
        {
            $valid_file = false;
            $message = 'Oops!  Your file\'s size is to large.';
        }

        //if the file has passed the test
        if($valid_file)
        {
            //move it to where we want it to be
            move_uploaded_file($_FILES['photo']['tmp_name'], 'uploads/'.$new_file_name);
            $message = 'Congratulations!  Your file was accepted.';
        }
    }
    //if there is an error...
    else
    {
        //set that to be the returned message
        $message = 'Ooops!  Your upload triggered the following error:  '.$_FILES['photo']['error'];
    }

}

不确定是什么...另外，尝试检查CPanel中的Namecheap php.ini以查看最大上传大小是什么，以便用户得到错误，而不是PHP错误或500。

基本文件上传 - 500内部服务器错误
