Parse BBCode

Hello,

I am currently trying to syndicate news from a certain forum. Take a look at my script (yes, I do have my own db class):

PHP Code:


		
			
include './functions.php';

            // start connection
            $db_host = "localhost";
            $db_user = "haha";
            $db_pass = "haha";
            $db_name = "haha";
            
            $db = new db;
            
            $db->connect($db_host, $db_user, $db_pass, $db_name);

            // which forum id should news be displayed from?
            define("FORUMID", "2");
            // enter prefix of your tables here (blank by default)
            define("PREFIX", "", true);
            // define how many number of articles you wish to display
            define("AMOUNT", "10");

            // run the query
            $query_sel_news = $db->query("select t.*,p.pagetext from ".PREFIX."thread t left join ".PREFIX."post p on(p.postid=t.firstpostid) where t.forumid = ".FORUMID." order by dateline desc limit 0,".AMOUNT."");

            // display the results and replace a few things... err.
            while($r = $db->fetch_array($query_sel_news)) {
    
                // our (simple) bbcode
                $bbcode = array("[B]", "[/B]", "[b]", "[/b]", "[I]", "[/I]", "[i]", "[/i]", "[U]", "[/U]", "[u]", "[/u]", "[img]https://vborg.vbsupport.ru/[/img]", "[img]https://vborg.vbsupport.ru/[/img]", "[center]", "[/center]", "[CENTER]", "[/CENTER]");
                // our html code :D
                $htmlcode = array("<B>", "</B>", "<b>", "</b>", "<I>", "</I>", "<i>", "</i>", "<U>", "</U>", "<U>", "</U>", "<img src=\"", "\">", "<img src=\"", "\">", "</p><p align=center>", "</p><p>", "</p><p align=center>", "</p><p>");
                // do the replacing
                $pagetext = str_replace($bbcode, $htmlcode, $r[pagetext]);
                // make it so there are LINE BREAKS ;o
                $pagetext = nl2br($pagetext);
                
                echo "<h2>".$r[title]."</h2><h3>".date("F jS, g:i A, Y", $r[dateline])."</h3><p>".$pagetext."</p><div id=\"content_left_news\">posted by ".$r[postusername]." | <a href=/forums/showthread.php?t=".$r[threadid].">comments (".$r[replycount].")</a> | <a href=/forums/showthread.php?t=".$r[threadid].">permalink</a></div>";
            }

            $db->close();

Ergh, but it's absolutely insane working with the freakin' bbcode. I've looked at this tutorial, but you see, I am selecting news from an "out-of-vbulletin" page (my main site index page). So, how can I get vB's bbcode parser on my index page to parse this text ($row[pagetext]).

You basically need to make a vB page out of your non-vB page. Here is an outline. Hope it helps. :)

Code:

<?php



error_reporting(E_ALL & ~E_NOTICE);



define('THIS_SCRIPT', 'whatever'); // SET ME

define('FWD', '/full/server/path/to/forum'); // SET ME

define('BWD', (($getcwd = getcwd()) ? $getcwd : '.'));



$phrasegroups = array();

$specialtemplates = array();

$globaltemplates = array();

$actiontemplates = array();



chdir(FWD);

require_once('./global.php');

chdir(BWD);



require_once(DIR . '/includes/class_bbcode.php');

$parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list());



$do_html = false; $do_smilies = true; $do_bbcode = true;

$do_imgcode = true; $do_nl2br = true; $cachable = false;



$query_sel_news = $db->query_read("QUERY HERE"); // SET ME



while ($r = $db->fetch_array($query_sel_news))

{

        $pagetext = $parser->do_parse(

                $r['pagetext'],

                $do_html, $do_smilies, $do_bbcode,

                $do_imgcode, $do_nl2br, $cachable

        );



        echo $pagetext . '<br /><br />'; // SET ME

}



$db->free_result($query_sel_news);

$db->close();



?>

Thanks so much!

However, the vBulletin template is pulled up and the 'pagetext' still isn't outputted. How do I get it so it just... a page, with the news pulled up (without the vB template).

I defined THIS_SCRIPT as 'news_index' so, do I need to set up a template or file for news_index somewhere? Sorry, never done anything like this with vB!

Thanks so much, I truly do appreciate it.

EDIT: Wait, the "vB template" that I am referring to is the "board offline" page. Whenever I login as admin (so I can view the forums and don't get the nasty offline error), I can view the page, but it spits an error out:

Fatal error: Call to undefined function: query_read() in /home/virtual/site13/fst/var/www/html/forums/includes/class_bbcode.php on line 472

Any ideas?

Try the following:

Code:

replace: $db->

with: $vbulletin->db->

Didn't do anything... I suspected that I shouldn't because I have my own DB class. ;)

Agreed, try replacing the vB query_read with your class equivalent.

mrTip

06-04-2006 11:59 PM

In class_bbcode.php? Where?

calorie

If your DB class is for the same database where vB is located, it might just be easier to be rid of your class. Otherwise you can try a class_bbcode.php file edit, replacing query_read with just query, but if you are going to file edit, then maybe set a constant in your script, and then file edit the vB script, so that for your script $db->query is used and for vB, it uses what it uses.

Okay, I edit line 472... it READ (past tense):

PHP Code:


		
			
            $smilies = $this->registry->db->query_read("
                SELECT *, LENGTH(smilietext) AS smilielen
                FROM " . TABLE_PREFIX . "smilie
                ORDER BY smilielen DESC
            ");

Now it says as follows...

PHP Code:


		
			
            $smilies = $this->registry->db->query("
                SELECT *, LENGTH(smilietext) AS smilielen
                FROM " . TABLE_PREFIX . "smilie
                ORDER BY smilielen DESC
            ");

The my news script works now. But will editing the class_bbcode.php file screw up my forums? Topics and bbcode still display properly as far as I can see. What concerns should I take?

If that's the only file edit you made, then it should be fine as vB also can do a $db->query that acts like a $db->query_read when SELECT is in the query.

EXCELLENT! Thank you SOOO much for your help. ;) I cannot tell you how much I want to syndicate news -- and now we've done it!

Thanks again. For your paitence too.

Hello,

I have yet another question. Is there a way to display a custom message if the board is offline? Because if the board is offline, it replaces the WHOLE page with the "vBulletin Message - Board Offline" page, which is not good.

Smilies also seem to have some trouble displaying themselves. They try and pull the images from images/smilies, but because my page is in the '/beta/' directory, it pulls it from /beta/images/smilies, which is an invalid URL. How can I correct the image path for the smilies on my syndicated news page?

Custom Message:

Code:

// plugin at global_start hook



if (THIS_SCRIPT == 'news_index' AND !$vbulletin->options['bbactive'])

{

        // either turn board on or set custom message

        // $vbulletin->options['bbactive'] = 1;

        // $vbulletin->options['bbclosedreason'] = 'msg';

}

Smilie Image Path:

Code:

// set a replacement variable



images/smilies/ => http://www.domain.com/forum/images/smilies/

mrTip

06-05-2006 10:29 PM

Err, where should I put that 'custom message' piece of coding? I have it right under the require_once(global.php), but it doesn't seem to be turning the board on.

EDIT: I'm a complete n00b to modding vB, so I have no idea what do to with that smilie image path piece of coding. Again, thank you for your paitence!

1) Go to vB ACP -> Plugin System -> Add New Plugin:

Code:

Product: vBulletin

Hook Location: global_start

Title: news_index active

Plugin PHP Code: code is below

Plugin is Active: Yes



if (THIS_SCRIPT == 'news_index' AND !$vbulletin->options['bbactive'])

{

        // either turn board on or set custom message

        $vbulletin->options['bbactive'] = 1;

        // $vbulletin->options['bbclosedreason'] = 'msg';

}

2) Go to vB ACP -> Styles & Templates -> Replacement Variable Manager -> Add New Replacement Variable:

Code:

Style: your choice

Search for Text: images/smilies/

Replace with Text: http://www.domain.com/forum/images/smilies/

Tip: also check out the vB online manual :)

Plugin works and I think the replacement variable manager works too, but it doesn't seem to be replacing the URL of the smilies on that news script.

calorie

06-06-2006 02:23 PM

If you are going to use a replacement variable, try the following:

Code:

/* do one of the following */



$pagetext = process_replacement_vars($pagetext); // and then you echo



/* or */



eval('print_output($pagetext);'); // does process_replacement_vars and echoes for you



/* or */



eval('print_output("' . fetch_template('your_template') . '");'); // where your_template has $pagetext in it

Otherwise be rid of the replacement variable and do something like:

Code:

$pagetext = str_replace('images/smilies/', 'http://www.domain.com/forum/images/smilies/', $pagetext); // and then you echo
