Question

I’m using Ajax to post contents, and I’m using http.send(encodeURIComponent(params)); for encoding … but I’m unable to decode them in PHP. I’m using POST so I didn’t think it required encode? I’m confused as to how I’m supposed to decode the values in PHP…

params = "guid="+szguid+"&username="+szusername+"&password="+szpassword+"&ip="+ip+"&name="+name+"&os="+os;
        //alert(params);
        document.body.style.cursor = 'wait';//change cursor to wait

        if(!http)
            http = CreateObject();  

        nocache = Math.random();

        http.open('post', 'addvm.php');
        http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        http.setRequestHeader("Content-length", params.length);
        http.setRequestHeader("Connection", "close");
        http.onreadystatechange = SaveReply;
       http.send(encodeURIComponent(params));

encodeURIComponent will encode all the &s and =s that delimit your key/value pairs. You need to use it on each part individually. Like so:

 params = 
 "guid="      + encodeURIComponent(szguid)     + 
 "&username=" + encodeURIComponent(szusername) +
 "&password=" + encodeURIComponent(szpassword) +
 "&ip="       + encodeURIComponent(ip)         +
 "&name="     + encodeURIComponent(name)       +
 "&os="       + encodeURIComponent(os);
    //alert(params);
    document.body.style.cursor = 'wait';//change cursor to wait

    if(!http)
        http = CreateObject();  

    nocache = Math.random();

    http.open('post', 'addvm.php');
    http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    http.setRequestHeader("Content-length", params.length);
    http.setRequestHeader("Connection", "close");
    http.onreadystatechange = SaveReply;
    http.send(params);
