How to handle BBCode - Eval or Parse out

[royli57]

Hello

I want to take some of the posts from one of my vbulletin threads and output it onto one of my webpages. The problem if I do this is that the BBCode tags are outputted with the rest of the tags.

I would like to either get rid of the bbcode all together or somehow evaluate it so that it is presentable on my page.

Does anyone know any functions that can help me deal with the bbcode in either way?

Thanks

Roy

strip_bbcode() or parse_bbcode() depends on if you want to parse it or strip it

Hmm, are these functions built into PHP? I tried strip_bbcode but it is undefined.

(haha, I did mean 'strip' by the way, thanks for the correction)

No, they are built into vBulletin

Hmm I see what you mean.

I wanted to do a database query and output the information directly. Vbulletin functions aside, can someone suggest a function or a way to strip or evaluate the bbcode?

Or is there a way I can integrate the vbulletin function into my page?

Ok this may be dumb but try including your vbulletin global.php or functions_bbcode.php then adding the strip_bbcode(); function

That would be the easiest way. Don't try to reinvent the wheel use what you have. If you don't have a vbulletin then you are going to have to use regulare expressions and write your own functions for strip and phrase bbcode.

colicab, I like your idea. If I can find the strip_bbcode function, I will gladly copy and paste it over to my page.

I checked globals.php and functions_bbcode.php but could not find that function though. Any idea where it might be?

[royli57]

Ah ha, I found it in functions.php.

PHP Code:

function strip_bbcode($message, $stripquotes = false, $fast_and_dirty = false)
{
    $find = array();
    $replace = array();
 
    if ($stripquotes)
    {
        // [quote=username] and [quote]
        $message = strip_quotes($message);
    }
 
    // a really quick and rather nasty way of removing vbcode
    if ($fast_and_dirty)
    {
        // any old thing in square brackets
        $find[] = '#\[.*/?\]#siU';
        $replace[] = '';
 
        $message = preg_replace($find, $replace, $message);
    }
    // the preferable way to remove vbcode
    else
    {
        // simple links
        $find[] = '#\[(email|url)=("??)(.+)\\2\]\\3\[/\\1\]#siU';
        $replace[] = '\3';
 
        // named links
        $find[] = '#\[(email|url)=("??)(.+)\\2\](.+)\[/\\1\]#siU';
        $replace[] = '\4 (\3)';
 
        // replace links (and quotes if specified) from message
        $message = preg_replace($find, $replace, $message);
 
        // strip out all other instances of [x]...[/x]
        while(preg_match_all('#\[([\w]+?)[^\]]*\](.*)(\[/\1\])#siU', $message, $regs))
        {
            foreach($regs[0] AS $key => $val)
            {
                $message = str_replace($val, $regs[2]["$key"], $message);
            }
        }
        $message = str_replace('[*]', ' ', $message);
    }
 
    return trim($message);
} 


Seems to work fine. Thanks everyone!

I would like to be able to parse instead of strip the bbcode, could someone help me with this?

When I try to include global.php I get:
Fatal error: Call to a member function on a non-object in /www/forums/includes/functions_bbcodeparse.php on line 384
