Basic BB Code

[SDP2006]

Could someone show me some basic examples to turn [b] into bold text and then [php] to highlighted code?

I only need the [php] and the [b] for now and I think I could use those examples to do the rest.

Thanks a million guys!

Thanks, after browsing some tutorials as well, I have came up with this.

function parse_bb($str){
        
        $this->string = $str;
    
        $search = array
        (
            '#\[B\](.+?)\[\/B]#is',
            '#\[I\](.+?)\[\/I]#is',
            '#\[U\](.+?)\[\/U]#is',
            '#\[COLOR=([a-z0-9\#+?)\](+.?)\[\/COLOR\]#mis',
        );
        
        $replace = array
        (
            '<strong>$1</strong>',
            '<em>$1</em>',
            '<span style="border-bottom: 1px solid;">$1</span>',
            '<span style="color: $1">$2</span>',
        );
        
        $this->parsed = preg_replace($search,$replace,$this->string); /*LINE 474*/
    } 

This is inside my class. Now, the [b] [i] and [u] works perfectly, but the [COLOR] does not work correctly. The error with it is

Warning: Compilation failed: missing terminating ] for character class at offset 39 in c:\server\htdocs\blog\blog.php on line 476

Could anyone see this error? Thanks.

Looks like vB parsed it, lol. I'll upload the code in a minute.

EDIT

Link in sig contains code. Very last function in class.

Without getting too deeply involved with the BB code, I think that

 '#\[COLOR=([a-z0-9\#+?)\](+.?)\[\/COLOR\]#mis',

should rather be

 '#\[COLOR=([a-z0-9\#]+?)\](+.?)\[\/COLOR\]#mis',

Note the additional square bracket after the hash sign in the middle.

[SDP2006]

Thanks for your help, but that still gives me an error

Warning: Compilation failed: nothing to repeat at offset 25 in c:\server\htdocs\blog\blog.php on line 476

Thanks a ton, mordred.

Yeah, I see it now too. The repetition in the middle makes no sense, since nothing's before the + sign. Give this repaired code a shot:

'#\[COLOR=([a-z0-9\#]+?)\](.+?)\[\/COLOR\]#mis',

[SDP2006]

All right! Now we're getting somewhere!

Thanks, I have a feeling I'll be back for more help. lol.

Thanks

You're welcome, and I have the same feeling as you.
But don't let this sarcastic comment of me restrain you from asking further questions. If the code above is what you made after reading the tutorials you requested recently, that's quite impressive, honestly.

[SDP2006]

Okay, I lied.

I modified some of it. Anyways, im in trouble again.

I'm wanting to PHP to be highlighted, can you elaborate?

Thanks

It's not one of the easiest tasks to perform, but you can try this quick hack and see if you can use it in your code. As to how it works, look up the "e" regex modifier in the manual, that's the main trick behind it. Another alternative would be to use preg_replace_callback(), but I'm tired right now to rewrite the code.

$str = 'foo [ php]
echo $str;
mysql_query($bla, $urgh);
[/ php] adsfa';

//	use the highlight_string() function combined with the "e" modifiere
$str = preg_replace(
	'#\[PHP\](.+?)\[\/PHP]#ise', 
	"highlight_string('<?php /*foo*/ ' . '\\1' . '//foo?>', true)", 
	$str
);

//	clean up redundant <?php PIs
$str = preg_replace('~(.+?foo\*/)|(//foo.+?$)~im', '', $str);

echo $str;

Hopefully the slashes stay as they are meant to stay... vBulletin, behave this time!

Edit: There ares paces before the php in brackets to prevent vB code parsing...

[SDP2006]

That uber lost me. Sorry could you edit this code to make it work? I'm kinda lost as to where to put things. Thanks a ton.

Thanks so much.

[SDP2006]

Mordred, my friend, wherfore art thou?

[mordred]

Don't worry, I'm still alive. You might take a look at the attached file.

EDIT: Argh, forgot the HTML code you wanted to surround the highlighted code with. Do you have to use font tags *shudder*?

[SDP2006]

Thanks a ton. I'll have to test it when I get home
