问题描述

我遇到了一个奇怪的问题，我的$ _POST数据没有通过.首先，这在我的本地主机上工作正常，但在我在网络上的共享主机上不起作用.形式如下:

I'm having an odd issue with my $_POST data not coming through. First, this works fine on my local host, but doesn't work on my shared host on the web. Here's the form:

<form action="/add" method="POST" enctype="multipart/form-data">

<div>
    Name : <input type='text' name='form[name]' class='form-text ' value="" style='width: 350px' placeholder="I.E. Boulder Vote Bus" maxlength="30"/>
</div>
<div>
    Description : <textarea name='form[description]' class='form-bigbox '/></textarea>
</div>
<div class='clearfix pull-left'>
    Logo: <input type="file" name='form[image_name]' class='' value="" accept="image/jpeg, image/jpg, image/png"/>
</div>
<div class='clearfix'></div>
<div>
    <span id='date' class='change'>
        Date : <input type='text' name='form[date]' id='datepicker' class='form-text ' placeholder="mm/dd/yyyy" value="" style='width: 160px;'/> 
    </span>
    Time : <input type='text' name='form[hr]' class='form-text ' style='width: 40px;' placeholder="01" value=""/> : <input type='text' style='width: 40px;' name='form[min]' class='form-text ' placeholder="00" value=""/> <select name='form[ampm]' class='form-text form-select' style='width: 60px;'><option value='am' >AM</option><option value='pm' >PM</option></select>
</div>
<div>
    Your Email : <input type='text' name='form[email]' class='form-text '  value="" style='width: 350px' placeholder="hero@voterides.com"/>
</div>
<div>
    Zip code : <input type='text' name='form[zipcode]' class='form-text '  value="" placeholder="80304"/> Radius : <input type='text' name='form[radius]' class='form-text '  value="" placeholder="25" style='width:50px;'/> mi
</div>
                    <div>
                            <input type='submit' class='form-submit btn-warning' value='Create a Ride' />
</div>
</form>

问题是，提交表单后，我没有$ _POST数据.如果我执行echo serialize($_POST);，我会得到a:0:{}.但是，如果这样做，echo file_get_contents('php://input');我得到以下信息:

Problem is, after I submit the form, I have no $_POST data. If I do echo serialize($_POST); I get a:0:{}. However, if I do, echo file_get_contents('php://input'); I get the following:

------WebKitFormBoundaryLCabCxfMMHCvWsAO

Content-Disposition: form-data; name="form[name]"



Some Name

------WebKitFormBoundaryLCabCxfMMHCvWsAO

Content-Disposition: form-data; name="form[description]"



Some Description

------WebKitFormBoundaryLCabCxfMMHCvWsAO

Content-Disposition: form-data; name="form[image_name]"; filename=""

Content-Type: application/octet-stream





------WebKitFormBoundaryLCabCxfMMHCvWsAO

Content-Disposition: form-data; name="form[date]"





------WebKitFormBoundaryLCabCxfMMHCvWsAO

Content-Disposition: form-data; name="form[hr]"





------WebKitFormBoundaryLCabCxfMMHCvWsAO

Content-Disposition: form-data; name="form[min]"





------WebKitFormBoundaryLCabCxfMMHCvWsAO

Content-Disposition: form-data; name="form[ampm]"



am

------WebKitFormBoundaryLCabCxfMMHCvWsAO

Content-Disposition: form-data; name="form[email]"





------WebKitFormBoundaryLCabCxfMMHCvWsAO

Content-Disposition: form-data; name="form[zipcode]"





------WebKitFormBoundaryLCabCxfMMHCvWsAO

Content-Disposition: form-data; name="form[radius]"





------WebKitFormBoundaryLCabCxfMMHCvWsAO--

此外，更奇怪的是，如果我将表格简化为仅3个元素，则它可以正常工作.任何3个元素都可以，但是4个元素却无效.此外，网站上的其他表单(包含3个以上元素)也可以正常工作.就是这个.

Furthermore, and odder, if I take the form down to just 3 elements, it works. Any 3 elements are fine, but 4 and it doesn't work. Additionally, other forms on the site (with more than 3 elements) work just fine. It's just this one.

以下是我的共享主机上的一些相关的PHP设置:

Here are some relevant PHP settings from my shared host:

PHP Version 5.3.16
max_execution_time  300 
max_file_uploads    20  
max_input_time  -1  -1
max_input_vars  1000    1000
memory_limit    128M    128M
post_max_size   500M    500M

如果是服务器设置，您知道它可能是什么吗?似乎是一个大小问题，但是传递的数据很少(所有这些都是很小的值).

If it's a server setting, any idea what it could be? Seems like a size issue, but there just isn't that much data being passed (all of these are small values).

我有一个htaccess，但是我不认为这是相关的(我使用的是codeigniter，这是标准的CI htaccess，我的其他表单也可以提交):

I have an htaccess, but I don't think it's related (I'm using codeigniter, and it's the standard CI htaccess, and my other forms submit a-ok):

AddDefaultCharset UTF-8
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /

    #Removes access to the system folder by users.
    #Additionally this will allow you to create a System.php controller,
    #previously this would not have been possible.
    #'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #When your application folder isn't in the system folder
    #This snippet prevents user access to the application folder
    #Submitted by: Fabdrol
    #Rename 'application' to your applications folder name.
    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

这是print_r($ _ SERVER)生成的内容(出于安全考虑，略作编辑):

Here's what print_r($_SERVER) produces (slightly redacted for security sake):
