So I got this to sort my posts and it works great:

<div class="sort">
   Sort by  
     <select onclick="if (this.value) { document.location = this.value; }">  
        <option value="" selected="selected">Latest first</option>  
        <option value="<?php echo $short_page_url; ?>?orderby=date">Oldest first</option>  
        <option value="<?php echo $short_page_url; ?>?orderby=title">Titles A-Z</option>  

But how can I have the order as separate dropdown/links to change between ASC and DESC? So it adds "&order=desc/asc" to the link when there's "?orderby=title/date" present?

I would do something like this:

<script type="text/javascript">
    function gup( name, default_value )
      name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
      var regexS = "[\\?&]"+name+"=([^&#]*)";
      var regex = new RegExp( regexS );
      var results = regex.exec( window.location.href );
      if( results == null )
        return default_value;
        return results[1];
    //here you can output default values for sortby and order by your php script
    var orderby = gup("orderby","");
    var order = gup("order","");
    function change_url() {
        var url = "<?php echo $short_page_url; ?>?orderby="+orderby+"&order="+order;
        document.location = url;

    //you still have to let javascript or php select the correct options
<div class="sort">
   Sort by  
     <select onclick="if (this.value) { orderby = this.value; change_url(); }">  
        <option value="" selected="selected">Latest first</option>  
        <option value="date">Oldest first</option>  
        <option value="title">Titles A-Z</option>  
     <select onclick="if (this.value) { order = this.value; change_url(); }">  
        <option value="asc">asc</option>  
        <option value="desc">desc</option>  
  • Thank you, this seems to be very close, but when the orderby is title the url goes to default ?orderby=date&order=asc when I try to select either asc or desc.

  • I edited the code, so that it will take orderby and order from url parameters.

  • notice : you still have to let javascript or php select the correct options.
