有时是空的 post 对象 - Joomla JRequest::get( 'post' );

Question

我正在使用表单传输在线游戏的数据。但很奇怪，有时 post 对象是空的？？？表单由 javascript 提交并设置值。

每点击 3-5 次后，传输的表单在“post”对象中为空。我在自定义 joomla 组件的 MVC 中使用此代码。

 <form method="post" action="/index.php?option=com_findme&amp;view=pair&amp;Itemid=40&    amp;lang=de" id="pair" name="pair">
<div class="ImagesSecondRow">
<div class="ImagePaneSmall">
<input type="image" onclick="mysubmit('clickeditem','1382378814')" value=""     src="http://www.dualda.com/media/com_findme/userimages/2356/thumbs/2356.jpg" onmouseout="outUserimage()" ;="" onmouseover="overUserimage('http://www.dualda.com/media/com_findme/userimages/2356/thumbs/2356.jpg')" class="ImagesInputPair" id="thumbimages" name="thumbimages">

<input type="hidden" value="com_findme" name="option">
<input type="hidden" value="pair" name="view">

</form>

<script type="text/javascript">


    function overUserimage(userimg){

    if (document.images)

      document.images["emptyuser"].src = userimg
     }

function outUserimage(){
   if (document.images)
      document.images["emptyuser"].src = "images/findme/empty_user.png"
}


        function mysubmit(elementname,value)
        {
            //�ndern des formular elements
            document.getElementById(elementname).value = value;
            //alert(elementname + ': ' +      document.getElementById(elementname).value);

            document.pair.submit();
        }


 </script>

传输后，我使用 JRequest::getVar 检查变量。但有时它们是正确的，有时却是空的

这是硬件限制。

我也遇到同样的问题这里

如果您检查错误日志，您应该会看到

PHP Warning:  Unknown: Unable to create temporary file, Check permissions in temporary files directory. in Unknown on line 0 
PHP Warning:  Unknown: POST data can't be buffered; all data discarded in Unknown on line 0

抱歉这个答案来晚了十年。我在尝试自己解决问题时发现了这篇文章。
