how can send multiple value by checkbox

Question

i have write code by ajax to sent name and roles by ajax, the name send success, but checkbox not send when choose more than 2 roles.

ajax code

   var HttPRequest = false;

   function doCallAjax(Mode,Page,ID) {
      HttPRequest = false;
      if (window.XMLHttpRequest) { // Mozilla, Safari,...
         HttPRequest = new XMLHttpRequest();
         if (HttPRequest.overrideMimeType) {
            HttPRequest.overrideMimeType('text/html');
         }
      } else if (window.ActiveXObject) { // IE
         try {
            HttPRequest = new ActiveXObject("Msxml2.XMLHTTP");
         } catch (e) {
            try {
               HttPRequest = new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e) {}
         }
      } 

      if (!HttPRequest) {
         alert('Cannot create XMLHTTP instance');
         return false;
      }

      var url = 'AjaxRolesPermRecord.php';
      var pmeters = "troles_Name=" + encodeURI( document.getElementById("roles_Name").value) +
                    "&tper=" + encodeURI( document.getElementById("per").value) +
                    '&myPage='+Page +
                    "&tID=" + ID +
                    "&tMode=" + Mode;

        HttPRequest.open('POST',url,true);

        HttPRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        HttPRequest.setRequestHeader("Content-length", pmeters.length);
        HttPRequest.setRequestHeader("Connection", "close");
        HttPRequest.send(pmeters);


        HttPRequest.onreadystatechange = function()
        {

             if(HttPRequest.readyState == 3)  // Loading Request
              {
               document.getElementById("mySpan").innerHTML = "load ...";
              }

             if(HttPRequest.readyState == 4) // Return Request
              {
               document.getElementById("mySpan").innerHTML = HttPRequest.responseText;
              }

        }

   }

and i get it on other page like this

foreach($selected as $key=>$val) 
{  
    $SqlInsertIntotable = mysql_query("INSERT INTO permissions_roles (id,permission_id,role_id) 
                                       value ('','".$val."','".$RoleID."')"); 
}

the problem is

Invalid argument supplied for foreach()

$selected is missing or empty..can't find it anywhere else in your code? — Oli

add an alert(pmeters) after the 'var pmeters' and check if all data is filled in — Oli

Pass all checkboxes values as an array in Javascript

This deals with your problem of selecting values and passing them to 'tper'

Are the checkboxs defined like an array? For example:

 <input type="checkbox" name="selected[]">

If you do it without ajax, but with a classic form, it works?
