在IE6中上传大于10Mb的文件时出现问题

Hey. This code works in most browsers, and even partially in IE6. It uploads files less 10Mb (approximately), but not anything larger. The code specifies that those files are permitted.

嘿。此代码适用于大多数浏览器,甚至部分在IE6中。它上传的文件少于10Mb(大约),但不是更大的文件。该代码指定允许这些文件。

Also, note that it seems like the entire file seems to be transferred to the servers before disregarded.

另外,请注意,似乎整个文件似乎在被忽视之前传输到服务器。

The website is at: www.mgxvideo.com/mgxcopy-alpha-3/ and can be reached by adding an item in the cart, and then clicking the upload function. Ideas?

该网站位于:www.mgxvideo.com/mgxcopy-alpha-3/,可以通过在购物车中添加项目,然后单击上传功能来访问。想法?

Here is the form:

这是表格:

<form enctype="multipart/form-data" action="upload_files.php?order_id=<?php echo $_GET['order_id'] ?>" method="POST">
    <table style="width:100%">
        <tr>
            <td valign="top">
                <span class="style1">Choose a file to upload: </span> 
            </td>
            <td valign="top">
                <input name="uploadedfile" type="file" />
            </td>
        </tr>
    </table>
    <input type="submit" value="Upload File" />
    <input type="hidden" name="action" value="add"/>
    <input type="hidden" name="MAX_FILE_SIZE" value="100000000" />
</form>

Here is a line at the top of upload_files.php:

这是upload_files.php顶部的一行:

$upload_output = upload_file($customer_id, $_REQUEST['action'], $_GET['order_id'], $_FILES);

And here is the upload_file() code:

这是upload_file()代码:

function upload_file($customer_id, $action, $upload_id, $FILES)
{
    $target_path = "uploads/";

    $target_path = $target_path . $customer_id . '_' . $upload_id . '_' . basename( $FILES['uploadedfile']['name']); 
    $str_output = '';

    if ($action == 'del' and file_exists($_POST['filepath']))
    {
        delete_file($customer_id, $_POST['filepath']);
        $str_output = '<span class="style1">File successfully deleted. If you are done uploading files, ' .
                '<a href="#" onclick="self.close();">click here</a> to close this window.</span>';
        setcookie("upload_out_txt", $str_output, time() + 300);
        setcookie("upload_out_b", "1", time() + 300);
    } else if ($action == 'add')
    {
        if (count_uploads($customer_id, $upload_id) >= 2)
        {
            $str_output = '<span class="style1">Problem: You have reached the maximum allowed uploads for this particular order. Please delete a file before continuing.</span>';
            setcookie("upload_out_txt", $str_output, time() + 300);
            setcookie("upload_out_b", "1", time() + 300);
        } else if (file_exists($target_path))
        {
            $str_output = '<span class="style1">Problem: A version of the file you are trying to upload already exists. Please delete the file from out servers before uploading again.</span>';
            setcookie("upload_out_txt", $str_output, time() + 300);
            setcookie("upload_out_b", "1", time() + 300);
        } else if (move_uploaded_file($FILES['uploadedfile']['tmp_name'], $target_path)) 
        {
            insert_to_database('uploaded_files', array($customer_id, $upload_id, 'now()', $target_path));
            $str_output = '<span class="style1">Success. The file was successfully uploaded. If you are done, <a href="" onclick="window.close();">click here to close the window</a></span>';
            setcookie("upload_out_txt", $str_output, time() + 300);
            setcookie("upload_out_b", "1", time() + 300);
        } else
        {
            $str_output = '<span class="style1">There was an error uploading the file, please try again!</span>';
            setcookie("upload_out_txt", $str_output, time() + 300);
            setcookie("upload_out_b", "1", time() + 300);
        }
    }



    return $str_output;
}

Here is my php.ini file, after I tried to implement a fix:

在我尝试实现修复之后,这是我的php.ini文件:

extension_dir="/kunden/homepages/30/d93769495/htdocs/extensions";
extension=uploadprogress.so;
upload_max_filesize=150M;
post_max_size=210M;
max_input_time=1800;
file_uploads=1;
memory_limit=240M;
max_execution_time=1800;

2 个解决方案

#1

Check the following settings in php.ini:

检查php.ini中的以下设置:

upload_max_filesize needs to be greater than 10 MiB (10M).

upload_max_filesize需要大于10 MiB(10M)。
post_max_size needs to be at least 40% greater than upload_max_filesize.

post_max_size需要比upload_max_filesize至少大40%。

The reason why this is required is that some old user-agents will upload using base64 encoding, which adds a 37% overhead to the data. Add mime headers, other post parameters, there are plenty of reasons to have it higher than upload_max_filesize.

需要这样做的原因是一些旧的用户代理将使用base64编码上传,这会增加37%的数据开销。添加mime标头,其他帖子参数,有很多理由让它高于upload_max_filesize。

max_input_time needs to be at least 900 (15 minutes).

max_input_time需要至少900(15分钟)。

You want to give enough time for the user to upload its file.

您希望为用户提供足够的时间来上传其文件。

This may not fix it but on one thread i was reading it said that IE6 needs to process the MAX_FILE_SIZE line before the filename input. So try moving the following line to the top of the form:

这可能无法修复它,但在我读它的一个线程上说IE6需要在文件名输入之前处理MAX_FILE_SIZE行。因此,请尝试将以下行移至表单顶部:

<input type="hidden" name="MAX_FILE_SIZE" value="100000000" />

I have no idea if it works and IE6 requires it to be parsed in that order, but that is what the thread I was reading said the solution was.

我不知道它是否有效,IE6要求按顺序解析它,但这就是我正在阅读的线程所说的解决方案。

Also check your php.ini max file size and timeout.

还要检查你的php.ini最大文件大小和超时。
