Form data not available after submission:

[gamesmstr]

I have the following code:  The AJAX call seems to be working just fine. but the form data is not available:  Can anyone help me?

 

      <table align="center" border="1" cellpadding="5" cellspacing="0" width="500">
        <tr><td colspan="3" align="center"><b>Warp to Trading Post Location (Costs 30 Energy)</b></td></tr>
        <tr>
          <form action="tradingpost.php" onsubmit="javascript:buytrap('warp'); return false;" method="post">
          <td>X value :
            <select name="warpx">
              <option value="0">0</option>
              <option value="100">100</option>
              <option value="200">200</option>
              <option value="300">300</option>
              <option value="400">400</option>
              <option value="500">500</option>
              <option value="600">600</option>
              <option value="700">700</option>
              <option value="800">800</option>
              <option value="900">900</option>
              <option value="1000">1000</option>
            </select>
          </td>
          <td>Y value :
            <select name="warpy" >
              <option value="0">0</option>
              <option value="100">100</option>
              <option value="200">200</option>
              <option value="300">300</option>
              <option value="400">400</option>
              <option value="500">500</option>
              <option value="600">600</option>
              <option value="700">700</option>
              <option value="800">800</option>
              <option value="900">900</option>
              <option value="1000">1000</option>
            </select>
          </td>
          <td>
            <input type="submit" value="Warp For 30 Energy" />
          </td>
          </form>
        </tr>
      </table>

 

And the Ajax:

 

   function createXMLHttpRequest() {
      if (typeof XMLHttpRequest != 'undefined') {
         return new XMLHttpRequest();
      }
      try {
         return new ActiveXObject("Msxml2.XMLHTTP");
      } catch (e) {
            try {
               return new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e) {}
      }
      return false;
   }

   function buytrap(type) {
      var xmlHttp11 = createXMLHttpRequest();
      
      params = "type=" + type;
      
      xmlHttp11.open("POST","ajax/ajax-tradingpost.php", true);
      xmlHttp11.setRequestHeader("Content-Type","application/x-www-form-urlencoded");

      xmlHttp11.onreadystatechange = function() {
         if(xmlHttp11.readyState == 4 && xmlHttp11.status == 200) {
            document.getElementById("tpost-window").innerHTML = xmlHttp11.responseText;
         }
      }
      xmlHttp11.send(params);
   }

 

And finally the function to retrieve the data:

 

//warp function
if ($type== "warp"){
	$warpx=$_POST["warpx"];
	$warpy=$_POST["warpy"];
	if ($questrecord[qstatus] != '0'){
		echo"<font color=red><center>You are not allowed to warp while you are on a quest!</center></font>";
	}
	elseif ($playerinfo[energy] < 30){
		echo"<font color=red><center>You do not have enough Energy to warp!</center></font>";
	}
	else{
		echo"<font color=red><center>You have now warped to the trating post located at $warpx,$warpy!</center></font>";
		mysql_query("UPDATE outland_user_data set ux='$warpx', uy='$warpy' where id = '$playerinfo[id]'");
//			mysql_query("UPDATE userdb set energy=energy-30 where id = '$playerinfo[id]'"); 
	}
	echo"<br><br>";
	?>
	<script>refresh_stats();</script>
    <?php
}

but the form data is not available:

 

What exactly do you mean?  Does it give you an error?  Does anything display?

[gamesmstr]

yes.  I get the following:

 

You have now warped to the trading post located at ,!

Have you tried to set the content-length and connection headers?

 

xmlHttp11.onreadystatechange = function() {
         if(xmlHttp11.readyState == 4 && xmlHttp11.status == 200) {
            document.getElementById("tpost-window").innerHTML = xmlHttp11.responseText;
         }
}
xmlHttp11.open("POST", "ajax/ajax-tradingpost.php", true);
xmlHttp11.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlHttp11.setRequestHeader("Content-length", params.length);
xmlHttp11t.setRequestHeader("Connection", "close");
xmlHttp11.send(params);

 

I could be wrong, considering I haven't used POST in ajax as much as GET, but I've always needed them.
