i'm trying to display the last threads in forumhome.
does anyone knows how can I set time/date limit in the query so it will get the latest threads in X Days \ Hours. If i dont do that it will look in the entire table that will cause an overload in the server.

PHP Code:


			
$forumperms = array();
foreach($forumcache AS $forum) {
 $forumperms["$forum[forumid]"] = fetch_permissions($forum['forumid']);
 // ## HIDE FORUMS WITHOUT THE CANVIEW OR CANVIEWOTHERS PERMISSION ##
 if (!($forumperms["$forum[forumid]"] & CANVIEW) || !($forumperms["$forum[forumid]"] & CANVIEWOTHERS)) {
  $limitfids .= ','.$forum['forumid'];
 }
}
unset($forum);
if ($vboptions['threadpreview'] > 0) {
 $previewfield = ', post.pagetext AS preview';
 $previewjoin = 'LEFT JOIN '.TABLE_PREFIX.'post AS post ON(post.postid = thread.firstpostid)';
}
$getthreads = $DB_site->query("
 ## GET LATEST THREADS ##
 SELECT pagetext, thread.*,thread.iconid AS threadiconid $previewfield
 FROM ".TABLE_PREFIX."thread AS thread
 LEFT JOIN ".TABLE_PREFIX."deletionlog AS deletionlog ON(thread.threadid = deletionlog.primaryid AND type = 'thread')
 $previewjoin
 WHERE open = '1'
 AND forumid NOT IN (0$limitfids)
 AND thread.visible = '1'
 AND deletionlog.primaryid IS NULL
 ORDER BY lastpost DESC LIMIT 5");
 while($thread = $DB_site->fetch_array($getthreads)) {
 $threads = true;
 $thread['message'] = parse_bbcode2($thread['pagetext'], 0, 0, 1, 1);
 if (strlen($thread['message']) > 500)
 {
 $tobecontinued = '... <a href="' . $vboptions[bburl] . '/showthread.php?t=' . $thread[threadid] . '">???? ?????</a>';
 $thread['message'] = substr($thread['message'], 0, 500).$tobecontinued;}
 $thread['title'] = fetch_censored_text(fetch_trimmed_title(unhtmlspecialchars($thread['title']), 68));
 $thread['date'] = vbdate($vboptions['dateformat'], $thread['lastpost'], 1);
 $thread['time'] = vbdate($vboptions['timeformat'], $thread['lastpost']);
 $thread['replycount'] = vb_number_format($thread['replycount']);
 // show goto new post
 $show['firstnew'] = false;
 $bbforumview = fetch_bbarray_cookie('forum_view', $thread['forumid']);
 if ($bbforumview > $bbuserinfo['lastvisit']) {
  $lastread = $bbforumview;
 } else {
  $lastread = $bbuserinfo['lastvisit'];
 }
 if ($thread['lastpost'] > $lastread) {
  $threadview = fetch_bbarray_cookie('thread_lastview', $thread['threadid']);
  if ($thread['lastpost'] > $threadview) {
   $show['firstnew'] = true;
   $show['icon'] = false;
  }
 }
 exec_switch_bg();
 eval("\$threadbits .= \"".fetch_template('forumhome_latestthreadbit')."\";");
}
if ($threads) {
 $show['latestthreads'] = true;
}
// memory saving
unset($thread, $threads);
$DB_site->free_result($getthreads);

thanks in advance

$cut = time() - 60*60*X*Y;
where X is the number of hours and Y is the number of days.. You're basically counting the number of seconds (60 seconds * 60 minutes * X hours * Y days) and subsctracting from the current time so you get a date in the past..

then you'd add a condition to your query: AND thread.dateline > $cut

zurih · #3 01-12-2005, 07:29 PM

can u please write down where I have to add this?

PHP Code:


			
SELECT pagetext, thread.*,thread.iconid AS threadiconid $previewfield
FROM ".TABLE_PREFIX."thread AS thread
LEFT JOIN ".TABLE_PREFIX."deletionlog AS deletionlog ON(thread.threadid = deletionlog.primaryid AND type = 'thread')
$previewjoin
WHERE open = '1'
AND forumid NOT IN (0$limitfids)
AND thread.visible = '1'
AND deletionlog.primaryid IS NULL
ORDER BY lastpost DESC LIMIT 5");

zurih · #4 01-12-2005, 07:52 PM

ok I figured it out...
but one thing though

$cut = 60*60*24*3;
does this mean it will show the last threads in the last 3 days OR in the last 3 days+24 hours+60 min+60 sec
because if i write 0*0*0*3 its not working.

and also, do u know how can I get the forum name which the thread exist?
what should I add..

thanks for your help!

* is multiplication. It needs to be in seconds, so 60 is a minute, 60*60 is an hour, etc.

rake · #6 01-13-2005, 06:20 AM

to get the forum name you'll need to join the forum table USING(forumid) which is equal to ON(thread.forumid=forum.forumid)

zurih · #7 01-13-2005, 07:26 AM

Link14716 thanks for the explanation

rake,
I'm getting database error when adding those lines
I added

PHP Code:


			
LEFT JOIN ".TABLE_PREFIX."forum ON (thread.forumid = forum.forumid)

I've done it wrong?

here is the code, just tell where to add the thing u wrote

PHP Code:


			
SELECT pagetext, thread.*,thread.iconid AS threadiconid $previewfield
FROM ".TABLE_PREFIX."thread AS thread
LEFT JOIN ".TABLE_PREFIX."deletionlog AS deletionlog ON(thread.threadid = deletionlog.primaryid AND type = 'thread')
$previewjoin
WHERE open = '1'
AND thread.dateline > $cut
AND forumid NOT IN (0$limitfids)
AND thread.visible = '1'
AND deletionlog.primaryid IS NULL
ORDER BY lastpost
DESC LIMIT 5");

plus, what should I add to display it in the template?

like this is the thread title:

PHP Code:


			
$thread['title'] = fetch_censored_text(fetch_trimmed_title(unhtmlspecialchars($thread['title']), 68));

thanks

Zurih, did you manage to get his working.. If so, would you be kind enough to post what changes you made to the original mod?

TECK · #9 01-28-2005, 02:45 AM

Hi zurih,

Please note that operators like "||" and "&" are grandpa segments of code... toss them really fast and replace them with the regular used ones.

About the time cut, this is really easy.

All you have to do in your query is set a timecut, in this way you don't do a full table scan... for example:

Code:

$threadbits = '';

$threadmaxtime = 2 // <-- no. of days here
$threadcut = time() - (86400 * $threadmaxtime);

if ($activethread) // <-- condition here
{
	// twisted condition to show the max number of threads, after the tables were partially scanned
	// just in case you have to many results...
	$threadmaxnumber = iif ($threadmax != 0 , 'LIMIT ' . $threadmax , '');

	// notice the partial table scan based on "lastpost" time limit,
	// that will ease the server quite a lot...
	$threads = $DB_site->query("
		SELECT threadid, forumid, title, replycount, postusername, postuserid, lastpost, views
		FROM thread
		WHERE $iforumperms AND lastpost >= $threadcut	AND visible = 1 AND open <> 10
		ORDER BY lastpost DESC $threadmaxnumber
	");

	// it's time to roll out the results...
	while ($thread = $DB_site->fetch_array($threads))
	{
		$thread['title'] = unhtmlspecialchars($thread['title']);
		$thread['title'] = xhtml_clean($thread['title']);
		if ($threadmaxchars != 0 and strlen( $thread['title']) > $threadmaxchars)
		{
			$thread['title'] = substr($thread['title'] , 0 , $threadmaxchars - 2) . '...';
		}
		$thread['time'] = vbdate($timeformat , $thread['lastpost']);
		$thread['date'] = vbdate($dateformat , $thread['lastpost']);

		eval('$threadbits .= "' . gettemplate('home_threadbit') . '";');
	}
	$DB_site->free_result($threads);
	unset($thread);
}

This was simply a basic example, just to make you understand the coding process for a partial table scan.
With my example, it should take you only few minutes to adapt it to the VB3 code, as Stefan used to say in the good old days.

Cheers.

Thanks for the reply teck

I have couple of questions...

Right now, this is my LATEST THREADES code in index.php:

PHP Code:


			
// START HACK 'Latest Threads On Forum Home'
// #################### PROCESS LATEST THREADS #######################
// fetch the permissions for each forum
$forumperms = array();
foreach($forumcache AS $forum) {
$forumperms["$forum[forumid]"] = fetch_permissions($forum['forumid']);
// ## HIDE FORUMS WITHOUT THE CANVIEW OR CANVIEWOTHERS PERMISSION ##
if (!($forumperms["$forum[forumid]"] & CANVIEW) || !($forumperms["$forum[forumid]"] & CANVIEWOTHERS)) {
$limitfids .= ','.$forum['forumid'];
}
}
unset($forum);
if ($vboptions['threadpreview'] > 0) {
$previewfield = ', post.pagetext AS preview';
$previewjoin = 'LEFT JOIN '.TABLE_PREFIX.'post AS post ON(post.postid = thread.firstpostid)';
}
$cut = 60*60*24*1;
$cut = time() - $cut;
$getthreads = $DB_site->query("
## GET LATEST THREADS ##
SELECT pagetext, thread.*,thread.iconid AS threadiconid $previewfield
FROM ".TABLE_PREFIX."thread AS thread
LEFT JOIN ".TABLE_PREFIX."deletionlog AS deletionlog ON(thread.threadid = deletionlog.primaryid AND type = 'thread')
$previewjoin
WHERE open = '1'
AND thread.dateline > $cut
AND forumid NOT IN (0$limitfids)
AND thread.visible = '1'
AND deletionlog.primaryid IS NULL
ORDER BY lastpost
DESC LIMIT 5");
 
while($thread = $DB_site->fetch_array($getthreads)) {
$threads = true;
$thread['message'] = parse_bbcode2($thread['pagetext'], 0, 0, 1, 1);
if (strlen($thread['message']) > 500)
{
$tobecontinued = '... <a href="' . $vboptions[bburl] . '/showthread.php?t=' . $thread[threadid] . '">???? ?????</a>';
$thread['message'] = substr($thread['message'], 0, 500).$tobecontinued;}
$thread['title'] = fetch_censored_text(fetch_trimmed_title(unhtmlspecialchars($thread['title']), 68));
$thread['date'] = vbdate($vboptions['dateformat'], $thread['lastpost'], 1);
$thread['time'] = vbdate($vboptions['timeformat'], $thread['lastpost']);
$thread['replycount'] = vb_number_format($thread['replycount']);
// show goto new post
$show['firstnew'] = false;
$bbforumview = fetch_bbarray_cookie('forum_view', $thread['forumid']);
if ($bbforumview > $bbuserinfo['lastvisit']) {
$lastread = $bbforumview;
} else {
$lastread = $bbuserinfo['lastvisit'];
}
if ($thread['lastpost'] > $lastread) {
$threadview = fetch_bbarray_cookie('thread_lastview', $thread['threadid']);
if ($thread['lastpost'] > $threadview) {
$show['firstnew'] = true;
$show['icon'] = false;
}
}
exec_switch_bg();
eval("\$threadbits .= \"".fetch_template('forumhome_latestthreadbit')."\";");
}
if ($threads) {
$show['latestthreads'] = true;
}
// memory saving
unset($thread, $threads);
$DB_site->free_result($getthreads);
// END HACK 'Latest Threads On Forum Home'

Now as you can see there, I added there

PHP Code:


			
$cut = 60*60*24*1;
$cut = time() - $cut;

This is not good?

what I have to replace with your code?

Thanks !
