    copied!<p>I am trying to send two pieces of info to a php. 1-) tent = zuzu 2-) zart = gagi</p> <p>target php simply echoes what I send so that I can check if it's working. This is the javascript:</p> <pre><code> function boka () { var mesparam = "tent=zuzu&amp;zart=gagi"; if (window.XMLHttpRequest){xmlhttp=new XMLHttpRequest();} else {xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");} xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 &amp;&amp; xmlhttp.status==200) {document.getElementById("response").innerHTML=xmlhttp.responseText;} } xmlhttp.open("POST","/mysite/oxifa/oxifat.php?tent=zuzu&amp;zart=gagi",true); //xmlHttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); //xmlhttp.setRequestHeader("Content-length", mesparam.length); //xmlHttp.setRequestHeader("Connection", "close"); xmlhttp.send(mesparam); } </code></pre> <p>This is oxifat.php that recieves the request:</p> <pre><code> &lt;?php echo " sign1 &lt;br&gt;"; echo next($_POST); echo next($_POST); echo next($_POST); echo next($_POST); echo next($_POST); echo $_POST['tent']; echo $_POST['zart']; echo $_REQUEST['tent']; echo $_REQUEST['zart']; echo "&lt;br&gt; sign2"; ?&gt; </code></pre> <p>As you can see I've included all sorts of things to echo out whatever is in $_POST but apparently there is nothing there and this is the response I get:</p> <p>sign1</p> <p>Notice: Undefined index: tent in C:\wamp\www\mysite\oxifa/oxifat.php on line 16</p> <p>Notice: Undefined index: zart in C:\wamp\www\mysite\oxifa/oxifat.php on line 17</p> <p>Notice: Undefined index: tent in C:\wamp\www\mysite\oxifa/oxifat.php on line 18</p> <p>Notice: Undefined index: zart in C:\wamp\www\mysite\oxifa/oxifat.php on line 19</p> <p>sign2 </p> <p>three lines about the "setRequestHeader" are in comment status. If I include them, I don't even get sign1. No response. What I figure out from this is everything is OK but I don't seem to understand how to use the post method to pass data to php. How do I do this? I have read everything on the net. I only do not know what "setRequestHeader" is for. One more thing: If I put ?tent=zuzu&amp;zart=gagi at the end of target URL, $_REQUEST thing works. But that's GET and not what I'm trying to do. What is the $_POST's deal? </p>
