Hi all am in need of your help am wanting to join two sql tables so that i show name of topic but username and date of the last post.

Am really finding this abit hard to do if any would please help thank you.

 

I know my query is not correct but really do need the help.

<?php$query = yasDB_select("SELECT * FROM forumposts");if ($query->num_rows == 0) {echo '<center><h3>We have no posts yet!</h3></center>';}else {$query = yasDB_select("SELECT forumposts.id,forumposts.date,forumposts.name,forumtopics.id,forumtopics,subject FROM forumposts, forumtopics WHERE forumtopics.subject ORDER by id asc limit 5");while($row = $query->fetch_array(MYSQLI_ASSOC)) {$subject = $row['subject'];$date = $row['date'];$name = $row['name'];if ($setting['seo'] == 'yes') {$topiclink = $setting['siteurl'].'forumtopics/'.$row['id'].'/1.html';} else {$topiclink = $setting['siteurl'] . 'index.php?act=forumtopics&id='.$row['id'];}?><a href="<?php echo $topiclink;?>"><?php echo $subject;?></a><br /><?php echo $name;?> - <?php echo $date;?><br><?php }}$query->close();?>

 

Tables for sql.

 

forumtopics = id,subject,cat,name,date

forumposts = id,text,date,name,topic

 

name = username

topic = topic id

 

from forumtopics cat is the catid from forum sql which we don't need to worry about forum sql i mean.

and topic is the topic id from forumtopics

I need to join forumtopics = subject with forumposts = id username and date.

I thought i had it working with this query but no.I am getting closer to fixing it but if any one knows a fix for this please post back.

$query = yasDB_select("SELECT forumposts.id, forumposts.name,forumposts.date,forumtopics.subject FROM forumposts INNER JOIN forumtopics ON forumposts.id=forumtopics.id ORDER by id desc limit 5");

So what error are getting? Or is it just not the data you expect?

 

(Note the proper usage of punctuation and capitalization in my sentences. Makes it easy to read, no?)

Here is error.

Error number: 0 - MySQL error Syntax error near '.Subject ON '.subject ON maxforumtopics.subject, forumposts.id=forumtopics.id ORDER by forump' on line 1 

Query: "SELECT forumposts.id, forumposts.name,forumposts.date,forumtopics.subject FROM forumposts INNER JOIN (SELECT forumposts.id, MAX(id) AS lastid FROM forumtopics GROUP BY forumposts.id) maxforumtopics.subject ON maxforumtopics.subject, forumposts.id=forumtopics.id ORDER by forumposts.id asc limit 5"

What is 'maxforumtopics.subject'. that is your problem.

Hi am not that good mysql i am still learning.

this is what am aiming for

 

We have more than 5 topics so....

Only the last five topics that had a post made would show.
The username and date is pulled from forumposts and then we pull the subject of that topic that had the post to look like this.....
--------------------------------------------------------------------------------
Latest topics - mostviewe username - date
topic  name  date
"My known issues for minix" username - date

"low quality thumbnails" username - date

"What would you like in ne" username - date

"PurpleBot is back" username - date

So say i made a post on "What would you like in ne"

It will then look like this.....
-------------------------------------------------------------------------------
What would you like in ne username - date

Latest topics - mostviewe username - date

My known issues for minix username - date

low quality thumbnails username - date

PurpleBot is back username - date

Guys i got it working and thank you for your reply's.

Here is what my query looks like if anyone comes to the same problem i had.

 

 "SELECT forumtopics.id, forumtopics.subject, forumposts.text, forumposts.date, forumposts.name FROM forumtopics INNER JOIN forumposts ON forumposts.topic = forumtopics.id ORDER BY forumposts.id DESC LIMIT 5"

This query works as its on my site.
