<p>Don't have an elegant solution at this point but wanted to share my findings for the future reference of others who encounter this problem. The source of the problem was 2 overriden php values in an .htaccess file. I had simply added these 2 values to increase the filesize limit for file uploads from the default 8MB to something larger -- I observed that simply having these 2 values in the htaccess file at all, whether larger or smaller than the default, caused the issue.</p>

<pre><code>php_value post_max_size xxMB
php_value upload_max_filesize xxMB
</code></pre>

<p>I added additional variables to hopefully raise the limits for all the suhosin.post.xxx/suhosin.upload.xxx vars but these didn't have any effect with this problem unfortunately. </p>

<p>In summary, I can't really explain the "why" here, but have identified the root cause. My feeling is that this is ultimately a suhosin/htaccess issue, but unfortunately one that I wasn't able to resolve other than to remove the 2 php overridden values above. </p>

<p>Hope this helps someone in the future as I killed a handful of hours figuring this out. Thanks to all who took the time to help me with this (MrMage, Andrew)</p>


blocks|key|1261717|text|这是另一个可能的原因--我的表单在没有WWW的情况下提交到domain.com。我设置了一个自动重定向来添加“WWW”。在此过程中，$_POST数组被清空。所以要修复它，我需要做的就是提交给www.domain.com|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1261718|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

<p>Here's another possible cause -- my form was submitting to domain.com without the WWW. and I had set up an automatic redirect to add the "WWW." The $_POST array was getting emptied in the process.  So to fix it all I had to do was submit to www.domain.com</p>

<h2>POST method</h2>

<p>We are going to make some modifications so POST method will be used when sending the request...</p>

<pre><code>var url = "get_data.php";
var params = "lorem=ipsum&amp;name=binny";
http.open("POST", url, true);

//Send the proper header information along with the request
http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http.setRequestHeader("Content-length", params.length);
http.setRequestHeader("Connection", "close");

http.onreadystatechange = function() {//Call a function when the state changes.
  if(http.readyState == 4 &amp;&amp; http.status == 200) {
    alert(http.responseText);
  }
}
http.send(params);
</code></pre>

<p>Some http headers must be set along with any POST request. So we set them in these lines...</p>

<pre><code>http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http.setRequestHeader("Content-length", params.length);
http.setRequestHeader("Connection", "close");
</code></pre>

<p>With the above lines we are basically saying that the data send is in the format of a form submission. We also give the length of the parameters we are sending.</p>

<pre><code>http.onreadystatechange = function() {//Call a function when the state changes.
  if(http.readyState == 4 &amp;&amp; http.status == 200) {
    alert(http.responseText);
  }
}
</code></pre>

<p>We set a handler for the 'ready state' change event. This is the same handler we used for the GET method. You can use the http.responseText here - insert into a div using innerHTML(AHAH), eval it(JSON) or anything else.</p>

<pre><code>http.send(params);
</code></pre>

<p>Finally, we send the parameters with the request. The given url is loaded only after this line is called. In the GET method, the parameter will be a null value. But in the POST method, the data to be send will be send as the argument of the send function. The params variable was declared in the second line as <code>lorem=ipsum&amp;name=binny</code> - so we send two parameters - 'lorem' and 'name' with the values 'ipsum' and 'binny' respectively.</p>


blocks|key|1261829|text|我可以使用enctype=“应用程序/x-www-form-urlencoded”来解决这个问题，因为缺省值是“文本/纯文本”。当您签入$DATA时，分隔符是一个表示“文本/纯文本”的空格和一个表示"urlencoded“的特殊字符。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1261830|亲切地问候弗兰克|1261831|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

blocks|key|1476601|text|在我的例子中，这是因为在使用jQuery提交表单之前，我使用jQuery禁用了页面上的所有输入。所以我改变了我的“禁用所有输入，甚至是‘隐藏’类型”：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1476602|$(":input").attr("disabled","disabled");+|code-block|syntax|javascript|1476603|要“仅禁用'button‘类型输入”：|1476604|$('input[type=button]').attr('disabled',true);|1476605|这样用户就不会不小心按下“go”按钮两次，从而进入我们的数据库！看起来，如果你在一个“隐藏”类型的表单输入上设置了“disabled”属性，那么如果表单被提交了，它们的值就不会被发送过来！|1476606|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

<p>In my case it was because I was using jQuery to disable all inputs on the page just before using jQuery to submit the form.
So I changed my "disable every input even the 'hidden' types":</p>

<pre><code>$(":input").attr("disabled","disabled"); 
</code></pre>

<p>to "disable only the 'button' type inputs":</p>

<pre><code>$('input[type=button]').attr('disabled',true);
</code></pre>

<p>This was so the user couldn't accidentally hit the 'go' button twice and hose up our DB!
It seems that if you put the 'disabled' attribute on a 'hidden' type form input their values won't be sent over if the form is submitted!</p>

blocks|key|1262481|text|好吧，我想我应该把我的箱子放在这里……在特定情况下，我将post数组设为空。表单运行良好，但有时用户抱怨他们点击了提交按钮，但什么也没有发生……经过一段时间的挖掘，我发现我的托管公司有一个安全模块，它可以检查用户的输入，并在发现时清除整个帖子数组(不仅仅是恶意数据)。在我的示例中，一位数学老师试图输入等式:+dy+%2B+dx+%2B0=+0；数据被完全擦除。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1262482|为了解决这个问题，我现在建议他在文本区输入数据，格式为dy+%2B+dx+%2B0=0，现在它可以工作了……这可以节省一些人的时间。|1262483|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

<p>OK, I thought that I should put my case here .... I was getting the post array empty in specific cases .. The form works well, but some times users complain that they hit submit button, and nothing happens .....
  After digging for a while, I discovered that my hosting company has a security module that checks users inputs and clears the whole post array (not only the malicious data) if it discovers so.  In my example, a math teacher was trying to enter the equation: dy + dx + 0 = 0; and data was wiped completely.</p>

<p>To fix this, I just advise him now to enter the data in the text area as dy + dx + 0 = zero, and now it works ....  This can save someone some time .. </p>


blocks|key|1477133|text|我刚刚花了几个小时来解决类似的问题。在我的例子中，问题是|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1477134|max_input_vars+=+"1000"|code-block|syntax|javascript|1477135|默认情况下，在php.ini中。我有一个非常大的表单，没有上传。php.ini设置为upload_max_filesize+=+"100M“和post_max_size+=+"108M”，这肯定不是我的问题所在。当表单中的变量超过1000个时，max_input_vars的行为是相同的。它返回一个空的_POST数组。我真希望我能在一小时前找到它。|1477136|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

<p>I just spent hours to fix a similar issue. The problem in my case, was the the</p>

<pre><code>max_input_vars = "1000"
</code></pre>

<p>by default, in the php.ini. I had a really huge form without uploads. php.ini is set to upload_max_filesize = "100M" and post_max_size = "108M" and it was surely not the issue in my case. PHP behavior is the same for max_input_vars when it exceeds 1000 variables in the form. It returns and empty _POST array. I wish I could have found that one hours, and hours ago.</p>

<p>same issue here!</p>

<p>i was trying to connect to my local server code via post request in postman, and this problem wasted my time alot!</p>

<p>for anyone who uses local project (e.g. postman):
use your IPv4 address (type ipconfig in cmd) instead of the "localhost" keyword.
in my case:</p>

<p>before:</p>

<pre><code>localhost/app/login

<p>after:</p>

<pre><code>192.168.1.101/app/login

blocks|key|1477207|text|我知道这很古老，但我想分享我的解决方案。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1477208|在我的例子中，问题出在我的.htaccess中，因为我添加了变量来提高我的PHP的最大上传限制。我的代码是这样的：|1477209|php_value+post_max_size+50MB
php_value+upload_max_filesize+50MB|code-block|syntax|javascript|1477210|后来，我注意到这些值应该类似于xxM而不是xxMB，当我将其更改为：|1477211|php_value+post_max_size+50M
php_value+upload_max_filesize+50M|1477212|现在，我的$_POST像以前一样返回了数据。希望这对将来的人有所帮助。|1477213|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|T|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|U|8|@]|9|@]|A|$G|H]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

<p>I know this is old, but wanted to share my solution.</p>

<p>In my case the issue was in my .htaccess as I added variables to raise my PHP's max upload limit. My code was like this:</p>

<pre><code>php_value post_max_size 50MB
php_value upload_max_filesize 50MB
</code></pre>

<p>Later I notice that the values should like xxM not xxMB and when I changed it to:</p>

<pre><code>php_value post_max_size 50M
php_value upload_max_filesize 50M
</code></pre>

<p>now my $_POST returned the data as normal before.
Hope this helps someone in the future.</p>


blocks|key|1262626|text|在我的例子中，当从超文本传输协议发送到超文本传输协议时，$_POST为空。问题是，当我将url固定为https://example.com时，表单有一个类似于//example.com的操作，问题就消失了。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1262627|entityMap|0|LINK|mutability|MUTABLE|url|https://example.com/^0|1E|J|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

<p>In my case, when posting from HTTP to HTTPS, the $_POST comes empty. The problem was, that the form had an action like this //example.com When I fixed the url to <a href="https://example.com" rel="nofollow noreferrer">https://example.com</a>, the problem disappeared.</p>


blocks|key|1262653|text|确保定义了每个字段的name属性。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1262654|这将在PHP上创建一个空帖子|1262655|<input+type="text"+id="Phone">|code-block|syntax|javascript|1262656|但是，这是可行的|1262657|<input+type="text"+name="Phone"+id="Phone">|1262658|entityMap^0|A|4|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@$9|T|A|U|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|V|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|W|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|X|8|@]|D|@]|E|$]]|$1|O|3|P|5|J|7|Y|8|@]|D|@]|E|$K|L]]|$1|Q|3|-4|5|6|7|Z|8|@]|D|@]|E|$]]]|R|$]]

<p>Make sure that the <code>name</code> property of each field is defined.</p>

<p>This create you an empty POST on PHP</p>

<pre><code>&lt;input type="text" id="Phone"&gt;

<p>But, this will work</p>

<pre><code>&lt;input type="text" name="Phone" id="Phone"&gt;

blocks|key|1477347|text|空的POST数组的另一个简单原因可能是没有使用关闭表单，然后添加第二个...当提交第二个表单时，POST数组将为空。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1477348|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

<p>I just moved it up to the production box for my client and now all form submissions are showing up as empty $_POST arrays.</p>
<p>I found a trick to verify the data is actually being passed using <code>file_get_contents('php://input');</code> and the data is showing up fine there -- the <code>$_POST</code>/<code>$_REQUEST</code> arrays are always empty.</p>
<p>I've also verified the content-type headers are correct as well via firebug (<code>application/x-www-form-urlencoded; charset=utf-8</code>).</p>
<p>This issue is happening regardless of whether a form is submitting via AJAX or a regular form submit.</p>
