I am wanting to call up the first post in a thread using the pagetext information in the post table. What would I use as a database query so that I get the pagetext associated with the first post in a thread?

I am wanting to use this in the forumdisplay.php file right before the call to the forumdisplaybit template.

I have tried using:

$post=$DB_site->query_first("SELECT pagetext FROM post WHERE threadid=$thread[threadid]");
$page=post[pagetext];

But I get varied results and it is is not the first post associated with the threadid.

Any ideas?

Thanks,
Parker

Code:

$post=$DB_site->query_first("SELECT pagetext FROM post WHERE threadid=$thread[threadid] ORDER BY postid");

Chen:

Thanks. That worked like a champ.

Now what would I use to keep the pagetext information limted to the first 30 characters followed by a ....? Is there a code to strip the vbcode and HTML code in the pagetext information? I would prefer to keep the vB code and HTML out of the information that is displayed.

Thanks,
Parker

Replace:

Code:

$page=$post[pagetext];

With:

Code:

$page=iif(strlen($url)>30,substr($post[pagetext],0,30)."..."),$post[pagetext]);

to only show first 30 chars followed by '...'.

Don't know about the vB code stripping though.

Instead of striping the vBcode would you use the bbcodeparse2 or bbcodeparse?

So you could have:

Code:

$page=iif(strlen($url)>30,substr($post[pagetext],0,30)."..."),$post[pagetext]);

followed by

$page2=bbcodeparse[$page];

or

$page2=bbcodeparse2[$page];

Do you think that would work ok?

What would you have to use if you wanted to parse the html in the pagetext then?

If you parse vB code, the output will simply have the equal HTML code.
For example, [color=red]text[/color] will be converted to <font color="red">text</font>.

Up to you.
To convert the text, use this:

Code:

$page=bbcodeparse2($page,1,1,1,1);

The 1 numbers are in this order:

Code:

$page=bbcodeparse2($codetoparse, $html, $imgcode, $smilies, $vbcode);

Chen:

Ok, bare with me a little more.

I put in:

Code:

$post=$DB_site->query_first("SELECT pagetext FROM post WHERE threadid=$thread[threadid] ORDER BY postid");

$page=iif(strlen($url)>30,substr($post[pagetext],0,30)."..."),$post[pagetext]);

$page=bbcodeparse2($page,1,1,1,1);

and got a parse error:

Then I put in just:

Code:

$post=$DB_site->query_first("SELECT pagetext FROM post WHERE threadid=$thread[threadid] ORDER BY postid");

$page=iif(strlen($url)>30,substr($post[pagetext],0,30)."..."),$post[pagetext]);

and also got a parse error.

So is $url supposed to be that or something else like $thread[threadid]. I mean where do the $url come from?

Also, is the bbcodeparse2 suppsed to have the numbers or
the $html, $vbcode, etc.?

Thanks again,
Parker

Sorry, my bad, use this code:

Code:

$post=$DB_site->query_first("SELECT pagetext FROM post WHERE threadid=$thread[threadid] ORDER BY postid");

$page=iif(strlen($post[pagetext])>30,substr($post[pagetext],0,30)."...",$post[pagetext]);

$page=bbcodeparse2($page,1,1,1,1);

(misplaced a parenthesis)

And in the bbcodeparse2() call you use 1 or 0 - 1 means it's parsed and 0 means it's not. :)

Sorry Chen it is still giving me a parse code error.

In forumdisplay.php I am putting:

Code:

$post=$DB_site->query_first("SELECT pagetext FROM post WHERE threadid=$thread[threadid] ORDER BY postid");

$page=iif(strlen($post[pagetext])>30,substr($post[pagetext],0,30)."...",$post[pagetext]);

$page=bbcodeparse2($page,1,1,1,1);

right above:

Code:

eval("\$forumdisplaybits .= \"".gettemplate('forumdisplaybit')."\";");



}

and getting a parse code error at line 527.

Also should that be

Code:

,30),"...", instead of ,30)."...", ?

Parker

If I put a right bracket before the eval line I get a parce code error at line 520.

Thanks,
Parker

This code in forumdisplay.php is working great for me, no errors or anything:

Code:

    } else {

             $backcolor = '{firstaltcolor}';

                 $bgclass = "alt1";

    }

    $post=$DB_site->query_first("SELECT pagetext FROM post WHERE threadid=$thread[threadid] ORDER BY postid");

    $page=iif(strlen($post[pagetext])>30,substr($post[pagetext],0,30)."...",$post[pagetext]);

    $page=bbcodeparse2($page,1,1,1,1);

    eval("\$forumdisplaybits .= \"".gettemplate('forumdisplaybit')."\";");



  }

  $DB_site->free_result($threads);
