retrieving multiple variables in php from ajax using $_POST

[tinks]

I cannot seem to retrieve using $_POST in php the variables that I passed using ajax.

i have something like:

{
        temp1 = "root";
        temp2 = "false";
    var url = "sample.php";
        var arg1 = "arg1="+ temp1;
        var arg2 = "arg2="+ temp2;
    var paramPost = arg1+"&"+arg2;
 
        ...        
         ajax.postIt(paramPost,temp2); 
}
 
 
function postIT(param, temp2) {
        // make a HTTP GET request to the URL asynchronously
                ...
        request.open("POST",url, true);
            request.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
            request.setRequestHeader("Content-length",param.length);
            request.setRequestHeader("Connection", "close");
        request.send("param="+param);
 
}
 

in my file.php, i have:

        ...
 
        if (isset($_POST['param']))
    {
        $args1 = $_POST['arg1'];   //gives out blank 
        $args2 = $_POST['arg2'];   //gives out false value (just right)
 
         }

i also tried:

        if (isset($_POST['param']))
    {
        $args1 = $_POST['param'];   //gives out "arg1=root" 
        $args2 = $_POST['arg2'];   //gives out false value (just right)
 
         }

am i doing it right? how can i retrieve just the value of $arg1 insteas of the
'name-value' pair?

help! thanks a lot!

use print_r function to print the $_POST Array

on line 21 of your ajax code

request.send("param="+param);

skip the variable inside the bracket.

you are actually sending
param=arg1=root&arg2=data(i guess false) so finally what are you sending
value of param is arg1=root and value of arg2 is data, and you are not sending arg1 at all
