    Javscript and PHP?

    Hey,

    I need help big time as my site has just completly buggered up lol!

    I just made a JS script which laoads data into a div (ajax style) which means page refreshes are not required... but currently it loads a $pagename.php "contents" in to the div - but i cannot have this method.

    What i need it to do - is generate a string with the $pagename.php and inject that to a variable into the div... heres what i got:


    This works as its meant to - but needs to be changed to suit my new method:
    Code:
    var bustcachevar=1 //bust potential caching of external pages after initial request? (1=yes, 0=no)
    var loadedobjects=""
    var rootdomain="http://"+window.location.hostname
    var bustcacheparameter=""
    
    function ajaxpage(url, containerid){
    var page_request = false
    if (window.XMLHttpRequest) // if Mozilla, Safari etc
    page_request = new XMLHttpRequest()
    else if (window.ActiveXObject){ // if IE
    try {
    page_request = new ActiveXObject("Msxml2.XMLHTTP")
    }
    catch (e){
    try{
    page_request = new ActiveXObject("Microsoft.XMLHTTP")
    }
    catch (e){}
    }
    }
    else
    return false
    page_request.onreadystatechange=function(){
    loadpage(page_request, containerid)
    }
    if (bustcachevar) //if bust caching of external page
    bustcacheparameter=(url.indexOf("?")!=-1)? "&"+new Date().getTime() : "?"+new Date().getTime()
    page_request.open('GET', url+bustcacheparameter, true)
    page_request.send(null)
    }
    
    function loadpage(page_request, containerid){
    if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
    document.getElementById(containerid).innerHTML=page_request.responseText
    }
    
    function loadobjs(){
    if (!document.getElementById)
    return
    for (i=0; i<arguments.length; i++){
    var file=arguments[i]
    var fileref=""
    if (loadedobjects.indexOf(file)==-1){ //Check to see if this object has not already been added to page before proceeding
    if (file.indexOf(".js")!=-1){ //If object is a js file
    fileref=document.createElement('script')
    fileref.setAttribute("type","text/javascript");
    fileref.setAttribute("src", file);
    }
    else if (file.indexOf(".css")!=-1){ //If object is a css file
    fileref=document.createElement("link")
    fileref.setAttribute("rel", "stylesheet");
    fileref.setAttribute("type", "text/css");
    fileref.setAttribute("href", file);
    }
    }
    if (fileref!=""){
    document.getElementsByTagName("head").item(0).appendChild(fileref)
    loadedobjects+=file+" " //Remember this object as being already added to page
    }
    }
    }

    With that and this below is how it all works on the site so far:
    Code:
    <a href="javascript:ajaxpage(login.php','contentarea');">Link to login</a>
    <div id="contentarea"></div>

    How ever i need to change this so instead of it just "loading the page contents" into the div i want the JS to do similiar idea of loading into the div but merely pass php into it so i can do this:

    Code:
    <a href="javascript:ajaxpage(login.php','contentarea');">Link to login</a>
    <div id="contentarea">
    <?php
    include($name); 
    //$name being "login.php" due to above href
    //$name value needs to be made from the JS from getting the
    //url in the HREF whilst not refreshing the page to do so.
    ?>
    </div>
    Can some one help me edit my JS to do what im trying to do ? I'm stuck at this point at trying to get it to do this final part.

    Code:
    <a href="javascript:ajaxpage('page.php?p=login','contentarea');">Link to login</a>
    page.php:

    Code:
    <?php
    $name=$_GET['p'];
    
    include "$name.php";
    ?>
    Would that do it?
