Question about query results.

[nathanrich]

I have a plugin that queries the 7 most replied-to threads in the last 24 hours and displays it in a separate section of my forum. The query shown below works exactly as I want it to, grabbing all the threads in the last 24 hours, ordering them by replycount and grabbing the top 7.

PHP Code:

$twentyfourago= time() - (3600 * 24);

$popularquery="SELECT * FROM `thread` where `dateline` >= $twentyfourago ORDER BY `replycount` DESC LIMIT 7";
    $merge=mysql_query($popularquery);
        echo mysql_error();

    while($popularrow=mysql_fetch_array($merge)){

$populardisplay .= "<b><a href='showthread.php?t=$popularrow[threadid]'>$popularrow[title]</a></b> <br />
<span class='smallfont'>&nbsp;     &nbsp;by 
<a href='http://www.nwfans.com/member.php?u=$popularrow[postuserid]'>$popularrow[postusername] </a></span><br/>";

} 


The threads are displayed with the most replied-to threads at the top and the 7th most replied-to at the bottom. What I'm wondering is how I can rearrange this so that it displays the threads by dateline with the oldest threads on top and the newest threads on the bottom. I would need to rearrange my query results after the query runs but before I display the results on the page.

SELECT * FROM thread WHERE dateline >= $twentyfourago ORDER BY dateline ASC LIMIT 0,7

Thanks, but that's not what I was asking. I want the top 7 most replied-to posts, and my current query grabs those. What I want to know is how I can take those 7 posts after I've grabbed them and reorder them by dateline. Sorry if that wasn't clear.

Try using a sub-query like this,

PHP Code:

$twentyfourago= TIMENOW - 86400;

$result = $db->query_read("
    SELECT *
    FROM (
        SELECT *
        FROM " . TABLE_PREFIX . "thread
        WHERE dateline >= $twentyfourago
        ORDER BY replycount DESC
        LIMIT 7
    ) as sub_results
    ORDER BY dateline DESC
");

$populardisplay = '';
while ($thread = $db->fetch_array($result))
{
    $populardisplay .= "<b><a href=\"showthread.php?t=$thread[threadid]\">$thread[title]</a></b>
        <br /><span class='smallfont'>&nbsp;     &nbsp;by
        <a href=\"http://www.nwfans.com/member.php?u=$thread[postuserid]\">$thread[postusername]</a> </span><br />";
} 


Another idea is to do it in PHP using array sorting.

Perfect, thanks.
