PHP variables and anchors in URL

This should work better

<a href="http://www.mypage.com/myfile.php?l=1&d=1&c=1#anchor1">Some link</a>
<div>
    <a name="anchor1"></a>
</div>

Note that the right way of doing it depends on what doctype you are using. You can read more about this for html5 here and for html 4.01 here

I guess the problem is that the id is added dynamically.

Then, you can refresh the hash AFTER adding the id and appending your element to the document

var h = location.hash;
location.hash = '';
location.hash = h;

Alternatively, you can use scrollIntoView:

document.getElementById(location.hash.substring(1)).scrollIntoView(true);

But to avoid errors you need some ifs:

var hash = location.hash.substring(1);
if(hash){
    var el = document.getElementById(hash);
    if(el && el.scrollIntoView){
        el.scrollIntoView(true);
    }
}

Some Browsers, will not automatically target your id, based on the URL hash. You may consider using JavaScript.

var doc = document;
function E(e){
  return doc.getElementById(e);
}
function offset(element){
  var x = 0, y = 0, e = element;
  while(e && !isNaN(e.offsetLeft) && !isNaN(e.offsetTop)){
    x += e.offsetLeft - e.scrollLeft;
    y += e.offsetTop - e.scrollTop;
    e = e.offsetParent;
  }
  return {left: x, top: y};
}
function YourSolution(listId){
  var parentId = E(listId), pcn = parentId.childNodes;
  for(var i=0,l=pcn.length; i<l; i++){
    if(pcn[i].nodeType === 1){
      var ac = pcn[i].childNodes;
      for(var n=0,m=ac.length; n<m; n++){
        var an = ac[n];
        if(an.nodeType === 1){
          an.onclick = function(){
            var el = offset(this);
            scrollTo(el.left, el.top);
          }
        }
      }
    }
  }
}

Put the above on an external JavaScript page called scroll.js. Now put the following code at the bottom of your body:

  <script type='text/javascript' src='scroll.js'></script>
  <script type='text/javascript'>
    YourSolution('listId');
  </script>
</body>
</html>
