Question

I have a post system in place

    <?php
/**
Display the results from the database
**/
$q = ("SELECT * FROM threads ORDER BY posted");
$r = mysql_query($q);

if(mysql_num_rows($r)>0): //table is non-empty
    while($row = mysql_fetch_assoc($r)):
        $net_vote = $row['votes_up'] - $row['votes_down']; //this is the net result of voting up and voting down
?>
<div class='entry'>
    <span class='link'>
        <?php echo $row['author']; ?>&nbsp;&nbsp;&nbsp;
        <?php $row['posted'] = date("jS M Y h:i",$row['posted']); echo $row['posted']; ?>
        &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<a href="http://twitter.com/share" class="twitter-share-button" data-count="horizontal" data-text="<?php echo $row['message']; ?>">
        Tweet</a><script type="text/javascript" src="http://platform.twitter.com/widgets.js"></script>
        <br/> 
        <div class='message'><?php echo $row['message']; ?><br/></div> 
            <?php echo "<a href='msg.php?id=$row[id]'/> Comments/Add comments $row[replies]</a>" ?> &nbsp;
        <?php echo "Likes: " . $row['votes_up'] . "&nbsp "; echo "Dislikes: " . $row['votes_down'] . "&nbsp"; ?>    
    </span>

    <span class='votes_count' id='votes_count<?php echo $row['id']; ?>'></span> 
    <span class='vote_buttons' id='vote_buttons<?php echo $row['id']; ?>'>
        <a href='javascript:;' class='vote_up' id='<?php echo $row['id']; ?>'></a>
        <a href='javascript:;' class='vote_down' id='<?php echo $row['id']; ?>'></a>

    <br/>
    </span>

</div>

<br/>
<?php
    endwhile;
endif;
?>

I want to add text that says ‘order by : Most recent | Most liked | least liked ‘
As you can see i think ive got it already posting most recent by defualt which is what i want.

But what i want also is when you click ‘Most liked’ & ‘least liked’ it sorts by ‘Vote_up’ ( likes) & ‘vote_down’ (dislikes) all on the same page and shows posts with most likes on them (most liked) and most dislike (least liked)

EDIT***

sorry my question is how can i add 2 functions that when on click sorts by ‘most liked’ and ‘least liked’

Answer 1

in html:

<a href='script.php?order=recent'>Recent</a>
<a href='script.php?order=liked'>Liked</a>
...

in php:

if ($_GET['order'] == 'recent') $order = "posted";
elseif ($_GET['order'] == 'liked') $order = "smth";
...
$q = "SELECT * FROM threads ORDER BY ".$order."";

but actually it’s better to use some js framework (i prefer extjs for that) to sort the output on client side
